An old tire poses a safety hazard. For some people, old tires might never be an issue. If you drive a typical number of miles, somewhere around 12,000-15,000 miles annually, a tire's tread will wear out in three to four years, long before the rubber compound does. But if you only drive 6,000 miles a year, or have a car that you only drive on weekends, aging tires could be an issue.
Hereâs why doing such an expensive, time-consuming test is worth it. Our last test of 20 regular all-season tire models had tread wear warranties ranging from 40,000 to 100,000 miles. You might guess that the longest wearing tires were those with 100,000 mile warrantiesânot so. A pair of these overachieving tread wear warranty tires rated just âaverage,â the same rating as the 40,000-mile tread wear warranty tire.
