Tire lifespan depends on several critical structural and operational factors that should be evaluated before purchase. Sidewall durability, tread depth, size compatibility, manufacturing date (DOT code), and load capacity must all be checked. Additionally, the correct tire type—whether for road use, off-road applications, forklifts, or other purposes—should be selected based on the intended usage, and the appropriate size should always be chosen in line with the manufacturer’s recommendations.
