Proper tire specs are important to extending the life of an automobile. Auto tire specifications include specific information relevant to the type of vehicle the tire is designed to fit. According to Car Videos, auto tires almost always include three sets of distinct numbers. Each set of numbers corresponds to separate tire specifications, and minor calculations are often able to help users distinguish whether certain tires are better or worse for their needs. Additional specifications refer to important matters, including air pressure and tread wear.
Auto tire sidewalls include numbers that correspond to size, weight load and speed, according to Car Videos. These numbers are important to ensure that users fit the proper tire to the correct automobile.
