The life of a tire can vary based on many aspects like the tire type, vehicle, driving conditions, etc. A treadwear rating is present on most tires as part of the UTQG codes that tell you how wear-resistant a tire is. The larger this number, the more wear-resistant the tire will be and hence will last longer. Most manufacturers also showcase treadwear warranties that can provide some light on the subject. Although these warranties only provide an estimate and claiming such warranties is an involved task.
