When purchasing new tires, it's important to know about how long you can expect them to last. Although tire manufacturers provide estimates on how many miles the tread is good for, tire longevity can be impacted by factors such as the elevation of the place they're driven, how curvy the roads are and if they're used in cold or hot climates. For all-season tires, the tread-life longevity is typically between 40,000 and 100,000 miles (64,374 and 160,934 kilometers) [source: ConsumerSearch]. High-performance all-season tires will only last from 40,000 to 70,000 miles (64,374 to 112,654 kilometers) and top-performance tires are sold without a guarantee on the tread life and usually don't last more than 25,000 miles (40,234 kilometers) [source: Motor Trend]. When you've determined the types of features you're looking for in a tire, consider how long you'd like the tires to last, and try factoring in if your commute could negatively impact the longevity of the tire tread.
