Proper tread depth is one of the most important safety features on your vehicle. Tread depth helps move moisture from underneath the tires so the rubber can grip the road. But what if you don’t notice changes in your tire treads? One of the great debates in the auto industry is the debate on the lifespan of a tire.
Some auto manufacturers suggest replacing tires after five years regardless of tread depth while others suggest ten years. Tire aging is typically not a problem for cars that are driven regularly because they will generally wear out and be replaced before aging becomes a problem. So what is an old tire? Vehicles that are used occasionally are the most susceptible to tire aging including collector cars and recreational vehicles. Spare tires hidden in the trunk or under the vehicle are also susceptible. Make sure your auto service professional checks your spare during every oil change! Tires may look fine on the outside, but chemical reactions caused by sun, heat and other climate conditions can result in structural and chemical changes.
According to the NHTSA, about 400 deaths per year can be attributed to tire failures. Tire failures could be caused by aging, improper installation, improper inflation, road hazards and other issues. The best way to ensure your tires will keep you safe, refer to your owner’s manual for the recommended maintenance schedules, tire pressures and policies on tire aging.
