What is the difference between R18 and R19 wheels?
1 Answers
The main difference between R18 and R19 wheels is the size of the tires. R19 tires are larger. The 'R' in R18 and R19 stands for diameter (in inches). The functions of car tires are as follows: 1. Support the entire weight of the vehicle, bear the load of the car, and transmit forces and moments in other directions. 2. Transmit traction and braking torque, ensure good adhesion between the wheels and the road surface to improve the car's power, braking, and passability. Together with the car suspension, they mitigate the impact during driving and dampen the resulting vibrations. 3. Prevent severe vibrations and early damage to car components, adapt to the vehicle's high-speed performance and reduce driving noise, ensuring safety, handling stability, comfort, and energy efficiency.
