Audi a4 uses Dunlop tires. Deng Lupu, a famous British brand, is good at applying high-tech achievements to the design of sporting goods, so that sports stars can reach their personal limits. The tire size is written on the side of the tire, and the rider can see it by himself. For example, 205/55r 16 means that the tire width is 205mm and the flatness rate is 55, R means radial tire, and 16 means that it can be mounted on the rim of 16 inch.
A flat ratio of 55 means that the sidewall height is 55% of the tread width. The greater the flattening ratio, the thicker the side wall, the better the comfort, but the worse the handling. The smaller the flattening ratio, the thinner the tire wall, the better the handling and grip, the worse the comfort and the greater the tire noise. Generally, the flat rate of automobile tires with large rims is small, while the flat rate of automobile tires with small rims is relatively large.

Tire is a round elastic rubber product that is assembled on various vehicles or machinery and rolls on the ground. 1845, R·w· Thomson, a Scottish-born civil engineer, invented pneumatic tires, and obtained a patent from the British government. The patent name was "Wheel Improvement of Carriage and Other Vehicles". The first pneumatic tire was born in February 10 of the same year. Tires are usually installed on metal rims, which can support the car body, buffer external shocks, achieve contact with the road surface and ensure the driving performance of the vehicle.
