Vehicle tire should support the vehicle weight, deliver its own driving force and the braking force to the road surface, alleviate the impact applied from the vehicle, and switch hemistich progression such as the very important role in the automobile parts. The tire is one of the important parts of the car; a small error can affect the driver and passenger’s safety. There are a number of problems with the tires, but generally we can divide them into two kinds: normal wear and abnormal wear. The normal tire wear occurs by driving, it can be replaced when mileage reaches recommended distance. The abnormal tire wear, unlike the usual wear, wears down tires unevenly or wears out only part of the tires. Until now, the method to check abnormal tire wear is that a mechanic checks tires with naked eyes and hands to confirm uneven tire wear. However, drivers are embarrassed when facing varied and vague rules of uneven wear, even for each tire. In this paper, the researchers have designed a system to check each tire wear by using one or two laser sensors in order to make up for this weakness and overcome the limits of subjective judgment and obtain objective, accurate judgment.
