Anyone know what the Revs per mile on these are?

I just picked up a set off a friend with the stock pirrellis still on them.

 

They are 742 revs per mile if memory serves.

 

742 revs per mile with a 235/55/17 tire

 

sorry got beat, thats what I get for answering the phone

 

742 RPMile

 

Hopefully you're taking the Pirellis off of them.
If not, check them for flat spots first.
The best balance in the world nor time can fix a POS pirelli with flat spots.

Thanks guys...Now I know how fast I'm going haha

 

Tirerack.com has the stock Piellis at 768 revs per mile.

Bigcustomwheels.com says 742 with a 27.2 inch diameter.

And if math serves me correctly 63360 inches in a mile, 27.2 inch diameter = 85.54 inches per rev, so the answer is pretty close to 742.

Conclusion, tirerack.com is wrong.
