Buying a new set of tires for your car is a significant investment. The main factor in a tire’s lifespan is the quality of the tires as indicated by the UTQG (Uniform Tire Quality Grade) treadwear rating. The higher the UTQG treadwear rating, the longer you can expect the tire life. A tire with a “600” treadwear rating is estimated to last twice as long as a tire with a “300” rating, and should go three times the distance of a “200” rated tire.
After the tire’s treadwear rating, the most important factor in the lifespan of a tire is how well they are maintained. Performing simple tire maintenance can make a big difference in the performance and lifespan of your tires. With good maintenance you’ll enjoy better traction along with optimal fuel economy and handling. Here are some tire tips to help your tires last longer.
1. Keep your tires properly inflated. The recommended inflation level in PSI (pounds per square inch) can found on the driver’s side inside door jam, or in your owner’s manual. It’s a good idea to check your tire pressure at least twice a month.
2. Rotate your tires regularly. Because tires wear at different rates, you can extend the lifespan and improve performance of your tires by rotating them once every 7,500 miles or 6 months.
3. Get a wheel alignment when needed. Wheels that are out of alignment from potholes and rutted roads can cause uneven tread wear as well as poor handling. If you notice your car is pulling to one side, or you see eccessive wear on one of more tires, schedule a wheel alignment to have the problem corrected.
4. Visually inspect your tires. Inspect your tires at least once a month for uneven wear and to ensure there are no cracks, bulges, or anything stuck in the tire tread.
5. Don’t mix tires. While it cost less to purchase one or two tires at a time, having mismatched tires can lead to uneven and faster wear and tear. Mismatched tires can also cause the car to handle unpredictably. Even if only one of your tires has worn out, don’t wait to replace all four tires.
