You should consider changing your tires based primarily on tread depth, tire age, and overall condition rather than a fixed time or mileage interval.
Key Guidelines for Changing Tires
- Tread Depth : Tires become unsafe when tread depth reaches 2/32nds of an inch or less, as this reduces traction, increases braking distance, and makes driving hazardous. You can check tread depth using tread wear indicators built into the tire, a tread gauge, or the penny test (if you can see all of Lincoln’s head on a penny inserted into the tread, it’s time to replace the tire)
- Tire Age : Most manufacturers and experts recommend replacing tires at least every six years regardless of mileage due to rubber degradation over time, which can cause cracks, brittleness, and increased risk of blowouts. Tires should never be used beyond 10 years even if they appear to have good tread
- Mileage Range : On average, tires last between 36,000 and 75,000 miles, but this varies greatly depending on driving habits, climate, and maintenance
- Other Signs : Replace tires if you notice performance issues such as loss of traction, frequent air pressure loss, visible sidewall damage, cracks, or color fading
- Vehicle Type Consideration : For all-wheel-drive vehicles, it’s often necessary to replace all four tires at once to avoid drivetrain issues, while other vehicles may allow replacing individual tires if the others are still in good condition
- Regular Checks : It’s advisable to inspect tires monthly and before long trips for tread wear, damage, and proper inflation. Rotating tires every 5,000 to 8,000 miles helps ensure even wear and prolongs tire life
In summary, you should replace your tires when the tread is worn below 2/32nds of an inch, when they are over six years old, or if they show signs of damage or degraded performance. Regular inspections and maintenance can help you determine the right timing for tire replacement, rather than relying solely on a fixed schedule
