Tyre basics
  • What is the difference between ZR and R ?

    Before 1990, ZR was used for high-performance tyres. Some manufacturers, however, still use this old designation ZR to indicate the speed rating of the Tyres. This is especially true for High Performance Tyres as it has somewhat become a tradition.

    ZR is now categorized into V, W, Y, or Z speed ratings.

    ZR simply means that your tyres are safe to operate till speed of 240 Kmph, - of course, where such speeds are even legal!

    Comparable speed ranges where R is used instead of ZR are:

    • V - 240 kmph
    • W - 270 kmph
    • Y - 300 kmph
    • (Y) - 300+ kmph
