What is the difference between 91w and 91v tires?
1 Answers
The difference between 91w and 91v tires lies in their speed ratings: The 91w tire represents a maximum speed of 270 km/h under load-bearing conditions, while the 91v tire represents a maximum speed of 240 km/h under the same conditions. The number 91 is the load index, indicating the load capacity standard the tire can bear at different air pressures. A 91-rated tire can support 615 kg at 2.5 bar pressure. Tires are circular elastic rubber products mounted on metal rims, designed to support the vehicle body, absorb external shocks, maintain contact with the road surface, and ensure driving performance.
