The former is for high-pressure tires, and the latter is for low-pressure tires. There are also many other markings, for example, D is used for light vehicles, F for medium vehicles, G for standard vehicles, and H, L, J for large luxury and high-performance vehicles. If an R is printed on the sidewall, such as 175R13, it indicates that the tire is a radial tire, with a width of 175mm (6.9 inches), mounted on a 13-inch (330mm) diameter rim, and usually the word RADIAL is also engraved. 2.

Following this are: tire type code, rim diameter (in inches), load index (allowable load mass code), and allowable vehicle speed code.
