Generally, the crown thickness of car tires is about 13mm (the crown pattern depth is 7mm, the crown thickness is 6mm), and the sidewall thickness is 5mm.
Car tires can be divided into pneumatic tires and solid tires according to different carcass structures. The vast majority of modern cars use pneumatic tires. According to the air pressure inside the tire, pneumatic tires can be divided into three types: high-pressure tires, low-pressure tires and ultra-low-pressure tires.
Low-pressure tires are commonly used in all types of cars. Pneumatic tires are divided into two types: tubeless tires and tubeless tires according to different compositions and structures. Cars generally use tubeless tires.
According to the arrangement of the inner ply and buffer layer of the tire, tires can be divided into radial tires and bias tires. Radial tires are commonly used on cars. There are markings on the sides of the tires.
