T 190 km / h Z ZR speeds above 240 km / h
H 210 km / h ZR if instructions marked tyre specifications appear ZR. Such as P275 / 40ZR17 93W, then the maximum speed rating ("93W" in the "W") of 270 km / h.
 
In recent standardized tyre identification made provision, in addition to infinitely variable Z speed rating outside of all grades of operating instructions are included speed symbols and load factor.
