What is the difference between Michelin ZR and R?
1 Answers
Here are the specific differences between Michelin ZR and R: 1. Tire speed rating: R indicates that the tire's maximum speed is 170 km/h; while ZR indicates that the tire's maximum speed exceeds 240 km/h. 2. Meaning: In tire parameters, R stands for radial tire. Radial tires are named because the internal cord ply arrangement is at a 90-degree angle to the centerline of the tread, resembling the meridians on a globe. ZR, on the other hand, is a high-speed tire code, such as P275/40ZR17-93W, where the maximum speed rating ("W" in "93W") is 270 km/h.
