Howdie guys. Lurking from the 993/964 to see if anyone can give me some info on your stock wheel/tire size. I'd like to know what is the back spacing on the rear 295/30/18's. I'm cornfused about ET, and find it easier to measure back spacing to see If I can fit the rear's on my Turbo 964 Cab. Also, what's back spacing for the front?

thanks a million.

Jaime

7.25" from the hub centerline to the inner tire mounting surface. Add about 1/2" for the width of the inner rim lip. It will be about 7.6" from the inner tire sidewall to the hub centerline with 295's, 8'' with 315's.

 

thanks ebaker! the "hub centerline" same as the hub mounting surface.....right? Also, is this for the rear only or both front and rear??
