There are many possible reasons why tires don’t last as long the manufacturer’s warranty. A common issue is the vehicle’s wheel alignment. Incorrect wheel alignment is the leading reason tires do not last as long as designed. A vehicle that is only 1/8 of an inch misaligned in the toe angle will cause 28 feet of sideways scrub in every mile traveled. This issue will likely not be noticed when driving, only seen after driving some time and when the tires are being inspected and the wear spotted. It is recommended to have wheel alignment angles measured and evaluated every year to ensure your vehicle is rolling as efficiently as possible as well as protecting your investment in tires!
