Your car’s tires are its only point of contact with the road, making them one of the most critical safety components of your vehicle. While you might know to check your tire pressure, another equally important factor often gets overlooked: tire tread depth. A simple penny can tell you everything you need to know about the condition of your tires and whether it’s time for a replacement. This guide will walk you through what tire tread is, why it matters, and how to perform the simple but effective “penny test” to ensure your vehicle is safe.

What is Tire Tread and Why Does It Matter?
Tire tread refers to the grooves and patterns on the surface of your tires. These designs are not just for looks; they are engineered to provide grip and stability. The primary function of tire tread is to channel water, slush, and snow away from the tire’s contact patch with the road. This helps maintain traction and prevent your vehicle from hydroplaning, which is when a layer of water builds up between the tires and the road surface, causing a dangerous loss of control.
As you drive, the friction between your tires and the road gradually wears down the tread. When the tread depth becomes too shallow, your tires can no longer effectively disperse water. This leads to several serious safety concerns:
Increased stopping distances: Worn tires take longer to stop, especially on wet or snowy roads.
Higher risk of hydroplaning: Even a small amount of water can cause a vehicle with bald tires to lose traction.
Reduced handling and grip: Your car may not respond as quickly during turns or emergency maneuvers.
Greater chance of punctures and blowouts: A worn-out tire has less structural integrity, making it more susceptible to damage from road debris.
Maintaining adequate tire tread depth is essential for your safety, the safety of your passengers, and others on the road.
Legal Requirements for Tire Tread Depth
To ensure road safety, most US states have established legal minimums for tire tread depth. The standard legal requirement is 2/32 of an inch. If your tires have less than this amount of tread, they are considered legally bald and unsafe for driving. Driving with worn-out tires can result in fines, failed vehicle inspections, and, most importantly, an increased risk of accidents.
It’s important to note that while 2/32 of an inch is the legal minimum, safety experts recommend replacing your tires well before they reach this point. Tire performance, particularly in wet conditions, starts to decline significantly once the tread depth wears down to 4/32 of an inch.
The Penny Test: A Step-by-Step Guide
You don’t need fancy equipment to check your tire tread. The penny test is a quick, easy, and reliable method that anyone can perform. All you need is a standard US penny.
Here’s how to do it:
1. Position the Penny: Take a penny and hold it so that Abraham Lincoln’s head is pointing down into one of the tire’s tread grooves.
2. Observe Lincoln’s Head: Look at how much of Lincoln’s head is visible.
If the top of Lincoln’s head is covered by the tread, your tires have more than 2/32 of an inch of tread depth remaining. They are legally safe, but you should continue to monitor them regularly.
If you can see the top of Lincoln’s head, your tread is worn down to 2/32 of an inch or less. This means your tires are legally bald and need to be replaced immediately.
3. Check Multiple Spots: Tires can wear unevenly. Repeat the penny tire test in several locations around each tire—on the inner, outer, and central parts of the tread—to get an accurate assessment of its condition. Uneven wear could also indicate issues with tire alignment or balancing.
While the penny test is a great rule of thumb, here are a few other methods you can use:
The Quarter Test
This works the same way as the penny test but provides a more conservative measure. Insert a quarter with Washington’s head facing down. If the tread covers the top of his head, you have at least 4/32 of an inch of tread left. This is the depth at which many experts recommend replacing tires for optimal wet-weather performance.
Tread Wear Indicator Bars
Most modern tires have small, raised bars built into the tread grooves. These bars are typically 2/32 of an inch high. As your tires wear down, these bars will become flush with the tread surface. If you see them, it’s a clear sign that you need new tires.
Tread Depth Gauge
For the most precise measurement, you can use a tire tread depth gauge. These are inexpensive tools available at any auto parts store and provide an exact reading of your tread depth. Best of all, they are easy to use.
When to Consider Replacing Your Tires
Besides failing the penny test, other signs indicate it’s time for a new set of tires. Regularly inspecting your tires for these issues is a key part of routine tire maintenance.
Age: Tires degrade over time, even if they aren’t used frequently. Most manufacturers recommend replacing tires every six to ten years, regardless of tread depth. You can find your tire’s manufacturing date on the sidewall as a four-digit code (e.g., “3219” means the 32nd week of 2019).
Visible Cracks or Bulges: Cracks in the sidewall or bulges on the surface are signs of structural damage. A tire with these issues could fail at any moment and should be replaced immediately.
Uneven Wear: If you notice that your tire tread is wearing down unevenly, it could be a sign of improper inflation, alignment issues, or a need for tire balancing. Addressing these problems early can extend the life of your tires. Regular tire rotation also helps ensure even wear.
Vibration: If you feel a vibration in the steering wheel or through the seat, it might be due to an internal tire problem or improper balancing. Have a professional inspect your vehicle.
Stay Safe on the Road
Your tires are your first line of defense against road hazards. Regular tire care, including monthly tread depth checks and pressure monitoring, is a small investment of time that pays huge dividends in safety. The penny test is a simple, effective tool that empowers you to take control of your vehicle’s safety.
If you’ve performed the penny test and found your tread is low, or if you’ve noticed any other signs of wear and tear, don’t wait. Protect yourself and your passengers by taking action.
Schedule a maintenance checkup with our certified technicians today. We can assess your car’s condition, check for alignment and balancing issues, and help you choose the right replacement tires for your vehicle.

Preparing Your Luxury Vehicle for Storage
Before placing your luxury car into storage, thorough preparation sets the foundation for successful long-term care.
Complete Cleaning Inside and Out
Start with a comprehensive wash and detail. Clean your vehicle’s exterior thoroughly, removing all dirt, salt, and contaminants that could cause corrosion over time. Don’t forget the undercarriage, where road salt and debris commonly accumulate.
Inside, vacuum all surfaces and clean leather upholstery with appropriate conditioners. Remove all food items, papers, and personal belongings that could attract pests or create unpleasant odors.
Essential Service and Fluid Checks
Schedule a pre-storage service appointment to address any maintenance needs. Check and change the oil if it’s nearing its service interval—fresh oil prevents contaminants from sitting in your engine. Inspect coolant levels and ensure the mixture ratio is appropriate for your climate zone. In colder regions, verify your coolant can handle freezing temperatures.
Top off brake fluid, power steering fluid, and windshield washer fluid. These steps prevent corrosion and ensure all systems remain properly lubricated during the storage period.
Fuel Stabilization and Tank Treatment
Fill your fuel tank completely to prevent condensation buildup, then add a high-quality fuel stabilizer designed for your specific engine type. This prevents fuel degradation and gum formation that can clog fuel injectors and damage your fuel system. Run the engine for a few minutes after adding the stabilizer to circulate it throughout the fuel system.
Protecting the Exterior
Your luxury vehicle’s exterior requires careful consideration during storage, starting with choosing the right location.
Indoor vs. Outdoor Storage Options
Indoor storage offers superior protection from weather elements, providing stable temperature and humidity levels while reducing theft and vandalism risks. However, it comes with higher costs and limited availability, particularly in urban areas. Indoor facilities may also pose pest infestation risks if not properly maintained.
Outdoor storage presents a more affordable option with greater availability, making it suitable for short-term needs. However, exposure to weather elements accelerates rust, paint damage, and interior fading while increasing security risks and requiring more extensive preparation.
For coastal regions, indoor storage becomes even more critical due to salt air exposure. Desert climates benefit from indoor storage to protect against extreme UV damage.
High-Quality Car Cover Selection
Invest in a breathable car cover specifically designed for your vehicle model. Breathable materials prevent moisture buildup while protecting against dust, scratches, and UV damage. Avoid plastic covers that trap moisture and can cause more harm than good.
If storing outdoors, choose a location with natural shade when possible. Even with a quality cover, minimizing direct sun exposure helps preserve your vehicle’s paint and interior components.
Tire Preservation Techniques
Proper tire care prevents flat spots and degradation during storage. Inflate tires to the recommended pressure, as they naturally lose air over time. For extended storage periods, consider placing your vehicle on jack stands to remove weight from the tires entirely, though this requires more preparation and storage space.
Luxury vehicle interiors require special attention to prevent deterioration and maintain their premium feel.
Leather and Upholstery Protection
Clean and condition all leather surfaces before storage. Apply a high-quality leather conditioner to prevent cracking and drying. For fabric upholstery, ensure all surfaces are clean and completely dry to prevent mold growth.
Mold and Mildew Prevention
Place moisture absorbers throughout the interior to control humidity levels. Silica gel packets or commercial moisture absorbers work effectively in enclosed spaces. Leave windows slightly cracked if storing in a secure indoor facility to promote air circulation, but avoid this practice with outdoor storage due to security and weather concerns.
Pest Control Measures
Remove all food items and crumbs that might attract rodents. Consider placing mothballs or dryer sheets in the interior and engine bay to deter pests, but use these sparingly and remove them before driving the vehicle again.
Battery Care
Your luxury vehicle’s battery requires special attention during extended storage periods.
Disconnecting the Battery
Disconnect the negative battery terminal to prevent drain from electronic systems that continue operating even when the car is off. Modern luxury vehicles have numerous electronic components that draw power continuously.
Battery Maintainers and Trickle Chargers
Consider investing in a quality battery maintainer or trickle charger designed for your vehicle type. These devices provide a slow, steady charge that keeps your battery at optimal levels without overcharging. This approach is particularly important for vehicles with complex electronic systems that require consistent power to maintain their memory settings.
Regular Maintenance During Storage
Even stored vehicles benefit from periodic attention.
Periodic Inspections
Check on your stored vehicle monthly if possible. Look for signs of pest intrusion, fluid leaks, or any developing issues that require attention.
Engine Startup Considerations
Starting your engine briefly every few weeks can help circulate fluids and prevent seals from drying out. However, only do this if you can drive the vehicle long enough to reach operating temperature—short startups that don’t fully warm the engine can cause more harm than good by introducing moisture into the system.
Preparing to Take Your Vehicle Out of Storage
When it’s time to reunite with your luxury vehicle, proper preparation ensures a smooth transition back to regular use.
Comprehensive Inspection Checklist
Begin with a thorough visual inspection. Check for any signs of damage, leaks, or pest intrusion. Examine tires for proper inflation and any signs of deterioration.
Fluid Top-Ups and System Checks
Inspect and top off all fluids including oil, coolant, brake fluid, power steering fluid, and windshield washer fluid. Reconnect the battery and verify it holds a proper charge.
Test the brake system thoroughly before driving. Stored vehicles often develop slight brake system issues that require attention before safe operation.
Test Drive and Professional Service
Conduct a brief test drive in a safe area to identify any unusual noises or handling issues. Pay attention to how the vehicle feels and sounds compared to your memory of its pre-storage condition.
Schedule a comprehensive service appointment for a detailed inspection and maintenance check. Professional technicians can identify issues that might not be apparent during your initial inspection.
Additional Regional Considerations
Your geographic location influences storage requirements. Colder climates require attention to coolant mixtures and potential freezing issues. Coastal areas demand extra protection against salt air corrosion—consider additional washing and protective coatings before storage.
Desert regions benefit from UV-protective measures and careful attention to rubber components that degrade quickly in extreme heat.
Always verify local regulations and HOA rules regarding long-term vehicle storage to avoid compliance issues.
Conclusion
Proper luxury car storage protects both your financial investment and your driving enjoyment. The time and effort invested in correct storage procedures pale in comparison to the cost of repairing damage from neglect.

Understanding Your Factory Warranty
A factory warranty is a manufacturer’s promise to repair or replace defective parts and systems in your vehicle for a specified period or mileage limit. Most new vehicles come with two primary types of coverage: bumper-to-bumper warranties and powertrain warranties.
Bumper-to-bumper warranties, also called comprehensive warranties, typically cover most components of your vehicle for three to five years or 36,000 to 60,000 miles, whichever comes first. This coverage includes electrical systems, air conditioning, infotainment systems, and most mechanical components, excluding routine maintenance items like brake pads and oil filters.
Powertrain warranties focus specifically on the engine, transmission, and drivetrain components. These warranties often extend longer than bumper-to-bumper coverage, sometimes lasting up to 10 years or 100,000 miles. Understanding these distinctions helps you know what’s covered and for how long, allowing you to make informed decisions about repairs and maintenance.
Following the Recommended Maintenance Schedule
Adhering to your manufacturer’s recommended maintenance schedule represents the most critical factor in maintaining warranty coverage. Car manufacturers design these schedules based on extensive testing and engineering data, specifying exactly when services like oil changes, filter replacements, and fluid checks should occur.
Common maintenance tasks include oil changes every 5,000 to 10,000 miles depending on your vehicle, tire rotations every 5,000 to 7,500 miles, brake fluid checks, coolant system maintenance, and air filter replacements. Each of these services plays a vital role in preventing larger mechanical issues that could compromise your warranty.
Neglecting scheduled car maintenance doesn’t just risk mechanical problems—it can void your warranty entirely. If your engine fails due to lack of oil changes, or your transmission breaks down because you skipped fluid services, the manufacturer can rightfully deny warranty coverage. The cost of these routine services pales in comparison to major repairs that warranty denial could force you to pay.
Keeping Accurate Car Records
Detailed record-keeping serves as your primary defense against warranty disputes and claim denials. Every service, repair, and maintenance activity should be documented with dates, mileage, parts used, and the service provider’s information.
Organize your records using digital files, cloud storage, or physical folders—whatever system works best for your lifestyle. Many vehicle owners find success with smartphone apps designed for car maintenance tracking, while others prefer traditional paper records kept in their glove compartment. The key lies in consistency and completeness.
These records become crucial evidence when filing warranty claims. Service advisors and warranty administrators use this documentation to verify that you’ve met your maintenance obligations. Without proper records, even legitimate warranty claims can face denial, leaving you responsible for expensive repairs that should have been covered.
Original Equipment Manufacturer (OEM) parts represent the gold standard for warranty compliance. These components meet the exact specifications your vehicle manufacturer designed, ensuring optimal performance, reliability, and continued warranty coverage.
Using non-OEM parts creates significant risks for your car warranties. Consider this scenario: a vehicle owner saves money by installing aftermarket brake pads instead of OEM parts. Later, when the brake system experiences premature failure, the manufacturer investigates and discovers the non-approved parts. The warranty claim gets denied because the aftermarket parts didn’t meet specifications, potentially causing the system failure.
When having your vehicle serviced, insist on OEM parts for critical components like engine parts, transmission components, brake systems, and electrical components. While aftermarket parts might cost less initially, they can void your warranty and lead to far greater expenses down the road.
Having Repairs Done by Qualified Technicians
The expertise of your service technician directly impacts your warranty coverage. Certified technicians like Autohaus Dierolf in Carmel, Indiana understand manufacturer specifications, proper procedures, and warranty requirements, reducing the risk of errors that could void your coverage.
Unauthorized or unqualified mechanics pose significant risks to factory warranty coverage. Consider this example: a vehicle owner attempts a DIY oil change but accidentally uses the wrong filter and doesn’t properly tighten the drain plug. The resulting oil leak damages the engine, but when the owner files a warranty claim, the manufacturer discovers the improper installation and denies coverage.
For warranty-related repairs and routine maintenance, choose authorized service centers whenever possible. These facilities maintain direct relationships with manufacturers, use approved procedures, and provide documentation that warranty administrators readily accept. While independent shops can perform quality work, authorized centers eliminate potential warranty complications.
Avoiding Modifications That Void the Warranty
Vehicle modifications present one of the fastest ways to compromise warranty coverage. Performance upgrades like turbochargers, engine tuning, suspension modifications, and exhaust system changes can all void car warranties by altering how your vehicle operates beyond manufacturer specifications.
These modifications affect your vehicle’s performance and reliability in ways that manufacturers haven’t tested or approved. Racing activities or competitive driving also void most warranties, as these uses exceed normal operating conditions that warranty coverage contemplates.
Before making any modifications, consult with your manufacturer or authorized dealer about potential warranty implications. Some modifications might only void coverage for related systems, while others could eliminate warranty protection entirely. Understanding these consequences helps you make informed decisions about customizing your vehicle.
Knowing Your Rights and Responsibilities
Understanding warranty laws protects you from unfair claim denials and helps you navigate disputes effectively. Federal regulations require manufacturers to honor valid warranty claims and prohibit them from voiding coverage without proper justification.
Your responsibilities include following maintenance schedules, using approved parts, maintaining proper records, and operating your vehicle within normal parameters. However, you also have rights, including the right to have warranty work performed at any authorized facility, the right to use aftermarket parts for non-warranty repairs without affecting coverage, and the right to dispute claim denials.
When warranty disputes arise, start by reviewing your warranty documentation and maintenance records. Contact the manufacturer’s customer service department to discuss the issue. Many disputes resolve through direct communication, but persistent problems might require assistance from consumer protection agencies or legal counsel.
Common Warranty Violations to Avoid
Several situations can inadvertently void your factory warranty coverage. Accident damage, vehicle misuse, and neglect all fall outside warranty protection since these result from external factors rather than manufacturing defects.
Environmental damage from floods, hail, or extreme weather conditions typically voids coverage, as does racing or competitive driving that exceeds normal use parameters. Using your vehicle for commercial purposes beyond manufacturer recommendations can also affect warranty coverage.
Understanding these exclusions helps you avoid car warranty violation and maintain protection for legitimate manufacturing defects and component failures.
Frequently Asked Questions
Can I take my car to any mechanic without voiding the warranty?
While you can use independent mechanics for routine maintenance, warranty-related repairs should be performed at authorized facilities to ensure proper procedures and documentation.
What happens if my warranty claim is denied?
Review the denial reason, gather supporting documentation, and contact the manufacturer’s customer service department. Many denials result from misunderstandings or incomplete information that can be resolved.
Do extended warranties work the same as factory warranties?
Extended warranties are separate products with different terms, conditions, and coverage areas. Read the fine print carefully to understand what’s included and excluded.
How important is keeping maintenance receipts?
Maintenance receipts provide crucial evidence of warranty compliance. Without proper documentation, legitimate claims may face denial due to inability to prove required maintenance was performed.
Key Points
Maintaining your vehicle’s factory warranty requires attention to detail, proper documentation, and adherence to manufacturer guidelines. By following recommended maintenance schedules, using OEM parts, working with qualified technicians, and keeping accurate records, you protect both your vehicle’s reliability and your financial investment.
The small effort required to maintain warranty compliance pays significant dividends when unexpected repairs arise. A single major warranty claim can save thousands of dollars, making these preventive measures incredibly valuable.
