Any one happen to know the speed rating for this tire?

No idea, but had them on my Mustang for a few years, and they had seen 130-150 mph several times

I ask because I'm still on 2.73 gears and to tune the car would have to get to around 175 to get to the top of 3rd. Looks like I may have to switch the front tires with the rears again in order to get the tune done.

On a side note, found out the Nitto NT05R are a W speed rated tire (168 mph).
Hopefully these Toyos are Z or Y rated...... Anyone know?

from what i am aware of, a Z rated tire means that it will be able to run 149+ mph. the Z will be in the tire description like this:

275/40ZR17

then this tire will be assigned a separate tire dedicated speed ratings above 149 separate such as a speed rating of Y which is 186+mph. so if there is not even a Z on them, then they should capable of over 149 on the street.

Thanks for that info, hopefully they will be ok to go with to get the tune done.
