I want to put 18 x 9.5s in front and 18 x 10.5s in back...will this cause any problems in terms of the computer...speedo, etc??? Thanks for the help!

 

Not if you use tires that keep the overall diameters close to stock. I think the wheel speed sensors have to see a 9+% difference in front to rear wheel speed for several seconds before they trigger an error code. I have 18x9.5 front w/275/35/18 tires (25.6") and 18x12 rear w345/35/18 rear(27.5")....no problems.
1.9"/25.6" is only a difference of 7.4%...not enough to trigger a code.

 

yeap they fit with no probs. thats what i have

 

I haven't had a single problem with my 18"... check my sig for sizes...

 

:sad: I wish I had 18's all the way around!! Makes the car look really low :eek: Good luck!! :thumbs:

 

:iagree: Yep, the only thing that matters is the overall diameter. Stock the difference front - back is about 1"; as long as you are relatively close, you won't have a problem. I've got 265/35s front, and 295/35s on the back, and have had no trouble at all.

Good luck,
Collin

 

ok, sounds good, thanks for the help

 

so should I run 265/35/18s up front and 295/35/18s out back?? Thanks

 

:yesnod: I like that combination...particularly in the BFG KDs!!

 

ok, sounds good...Ill be goin with the Kuhmos (just graduated college = still poor)

 

I like the 275/35s up front because they approximate the stock 17" diameter and because they provide a little more sidewall to handle the potholes in CA's roads and hiways...

 

:iagree:

 

I emailed you a spreadsheet with tire aspect ratios. It may help you to see the overall dimensions of wheel/tire combinations and wheel widths more clearly. I got it from the forum last year.

 

thanks...that was a big help

 

yeap, same exact set-up i have
