275/??/18

Cesar2cool · March 14th, 2008, 01:02 PM

275/40 or 45/18zr
not sure lol

GTsetGO · March 14th, 2008, 01:04 PM

i would say that it is a little off due to having a bigger profile and rim.

Cesar2cool · March 14th, 2008, 01:07 PM

By how much do you think?
not that much though right?

I agree but not enough to worry about.

Cesar2cool · March 14th, 2008, 01:07 PM

oh ok then

Your are prolly rolling on 245/40-18 and the difference between that and the stock 205/65-15 is less then 2 mph difference on the speedo. The stock tire profile is about the same difference as the bigger rim combined with the lower profile tire.

I'm guessing you never calibrated your speedo after the 4.10 install? If so the only thing that sucks about that is all the additional miles your going to be racking up on the odometer.
