What is the difference between car tyres 55R and 60R?
The flat ratios of the 2 tires differ. 60 and 55 represent the flat ratio of the tire, simply speaking, the aspect ratio of the tire is the percentage of the tire cross section divided by the tire width, and the R represents the radial tire.
The flat ratio shows a large area, and the tire can bear great pressure. The reaction is very sensitive to the road surface, the lateral resistance of the cornering is strong, and the controllability of the vehicle is strong. The vehicle width, diameter, lower than the flat tire, but strong maneuverability, visual effects and give people a strong feeling.
The high ratio of the tire sidewall flat due to long, strong buffering capacity, relatively high comfort, but the feel of the road is poor, the lateral cornering resistance is weak; on the other hand, a low aspect ratio, large diameter of the tire sidewall, because of short, wide tread, and then
