The environment in which you drive your car plays a significant role in how quickly your tires wear out and need to be replaced. Even high quality cooper tires are going to suffer when constantly asked to perform in extremely hot climates. Dry conditions also cause tires to break down faster than humid one. Cold climates, especially those with lots of snow and ice, expose tires to sand, gravel, and deicing chemicals that can be increase the rate of deterioration.
The tread of your tire will be your best indicator that it is time to buy new tires and wheels for your vehicle. You should check the tread weekly, as well as inspect the tires for surface damage or road debris that will negatively impact performance. A good plan is to check the tire pressure, tread, and general condition of the tires at the beginning of the work week. You should also do a closer inspection before and after going on long road trips.
You can use the reliable penny test or check the specs for your given tire brand and measure the tread. If it falls below the standards, then it’s time to buy new tires. You may have tires that have a built in wear indicator that will tell you when the tread is too low. It’s a good feature to look for when buying new tires.
Driving a vehicle with a worn out tread is extremely hazardous. These tires have less traction and maneuverability, making them more prone to skidding and slipping. You are also much more likely to have a blowout which can result in a serious accident. It’s much better to just replace the tires as soon as the tread approaches the danger zone.
