Understanding of tire identification
The correct use of the tire first to know the tire, know the first to know the tire to see the signs on the tire.
Such as 195 / 65R15 (91v) tire identification of Guangzhou accord 2.3i. It said tread width 195 mm, width and height than 65R15 refers to the radial tire, tire diameter 15 inches, the load index of 91 said maximum carrying capacity of 615 kg, speed code V, said safe speed is 240 km.
Some tire also marked with M + s, said the application of mud, snow, tubeless said tubeless, TreadWear said tread wear index.
For car tires, one of the important parameters is the high aspect ratio, which is the flat rate, which is derived from the formula (H / W), the H refers to the tire cross-section height, W refers to the maximum width of the tire on both sides.
Smaller numerical formula that the transverse cross section of the tire is flat (see "technology" - "chassis -" tire "" modern car tires ").
Some of the owners in order to make the car better driving stability, like to switch to a low aspect ratio tire, for the exchange of different ratio of height to width of the tire, the best to the same diameter based, if the tire diameter and rim diameter remains unchanged, the width and height than the lower tread will appear to be more broad, contact surface will more, make the car driving and steering is more stable. If is not the same as the tire diameter must be replaced together with the wheel rim, it involves range is larger, such as wheel drum is connected block matching, suspension geometry parameters and turning radius are possible association, must be careful.
