S - 112mph
T- 115
H- 125
V- 149
Z- 168+
W- 168
Y- 189

Most W and Y rated tires are considerd Z rated tires. Some tire companies do it differently, and that Z has been just a designation for either a W or Y rated tire.
Not many Z rated tires, its usually a big jump from V to W now. Z used to signify very fast, untill W and Y rated tires came out.

Anything else?
