Can someone take a sec a list the different speed ratings for tires?

[blackbuick87]

H rated?
S rated?
ZR rated?

WTF are they good for, top end wise? I have ZR rated Comp TA's, so how fast can I go before they disintegrate?

TIA

Keep in mind it is not just speed but speed over a period of time.

I am not sure, but...

The "H" are rated to 130.
The "Z", don't know about the "R", are 150+
The "S" I think are rated at 112.
The "V" were up to 149.
The "T" were 118.
