[MacLila]

235/65R17 indicates that the tire has a section width of 235 millimeters, an aspect ratio of 65, R stands for radial tire, and 17 represents a 17-inch rim diameter. The following are the functions of automotive tires: 1. Force transmission medium: Tires serve as the medium for transmitting forces between the vehicle and the road surface, including driving force, braking force, and steering force, thereby enabling operations such as driving, braking, and steering. 2. Supporting vehicle load: The load of the vehicle causes the tire to compress until the average pressure on the tire's contact area balances with the internal inflation pressure. 3. Damping and absorbing vibrations and impacts during driving: This prevents early damage to vehicle components caused by severe vibrations. At the same time, it adapts to high-speed driving conditions, reduces driving noise, and ensures safety, comfort, handling stability, and fuel economy.
