We know that everybody wants a good warranty for pretty much anything they buy, but unfortunately, tire warranties can be a tricky subject. Most tires come with some combination of a treadlife and uniformity warranty. The treadlife warranty is determined by how many miles your tire should reasonably be able to travel without giving out. This is normally between 30,000 and 90,000 miles depending on what type of tires you have. Summer tires will almost always have a lower mileage warranty since they wear out quicker. That’s the price you pay for a softer, grippier rubber compound. The uniformity warranty is for when your tire excessively vibrates or causes a noticeable disturbance with the smoothness of your ride. These normally must be reported before you wear out the first 2/32” of your tire tread. While this might all sound nice and straightforward, we promise you it isn’t. When buying tires, it is always important to carefully read the fine print of the warranties, as it is very common for them to have time constraints. Many of the treadlife warranties are fractional, meaning that you only get credit for the difference between whatever mileage the tire reached and the assigned warranty mileage.
