What’s the difference between a zr tire and r tire?
A: The difference between the R rated and ZR rated tires is that the R rated tires have a maximum speed capability above 240 km/h (149 mph), while for ZR tires the maximum speed capability may be above 300 km/h (186 mph). A “Z” rating can mean different things. While it nearly always means a high performance tire for high-performing sports cars, “Z” may actually appear in the middle of a tire’s size information. When it does, it represents either a maximum speed of more than 149 mph (240 kph) or 186 mph (300 kph).The letters ZR on the sidewall relate to a tyre’s speed rating, which in this case is 150mph. That means it should not be driven at speeds in excess of 150mph (240kmph) – of course, where such speeds are even legal! Before 1990, ZR was used for high-performance tyres.
