What Is Meant by Speed Rating? The speed rating of a tire indicates the speed category (or range of speeds) at which the tire can carry a load under specified service conditions. The speed rating system used today was developed in Europe in response to the need to control the safe performance of tires at standardized speeds.
A Z tire means that the top speed rating of the tire is not designated, and you must consult the manufacturer to obtain the rating. A W (ZR) tire's top speed rating is 270 km/ â¦ h or 168MPH. A Y (ZR) tire's top speed rating is 300 km/h or 186 MPH. A ZR tire is rated at top speed of 300 km/h or 186 MPH, AND ABOVE. No, Z tires, and ZR tires are not the same.
