RebekahsZ Posted May 9, 2013 Share Posted May 9, 2013 (edited) Car has coilover and camber plates set at -3 camber in front, -2.5 camber in rear, 5 caster. Measured tread width is 9.5". The sidewalls seem to want 9" wide rims instead of 8s, but the clearance between the "rim saver" portion of the sidewall is super close to the spring seat. I jacked the car up on the diagonal opposite side to compress the suspension to ensure clearance with a bump. Closest clearance is to rear spring seat. I think this is pretty close to the max tire I can fit on this car. Edited May 9, 2013 by RebekahsZ Quote Link to comment Share on other sites More sharing options...
74_5.0L_Z Posted May 9, 2013 Share Posted May 9, 2013 I ran 245/45/16 when I had the stock bodywork. Check your front tire clearance at full steering lock in both directions. Mine would rub on the frame rails near the sway bar mount. I had to limit the rack motion to prevent contact. Quote Link to comment Share on other sites More sharing options...
BluDestiny Posted May 9, 2013 Share Posted May 9, 2013 (edited) It does look like it will contact in turns on the front lip. Is this without a spacer? or do you need a spacer? Edited May 9, 2013 by BluDestiny Quote Link to comment Share on other sites More sharing options...
RebekahsZ Posted May 9, 2013 Author Share Posted May 9, 2013 Thanks fellas. I have installed shaft collars on the steering rack to limit steering travel. I checked for TC rod rub but I did not check the front portion of the sway bar. Will do. Quote Link to comment Share on other sites More sharing options...
madkaw Posted May 10, 2013 Share Posted May 10, 2013 I'm running 245/45/17's all around with 8.5" rims +4 offset. Fronts clear everything- only rears rub. If I could get 2.5 camber- the rears might clear Quote Link to comment Share on other sites More sharing options...
RebekahsZ Posted May 10, 2013 Author Share Posted May 10, 2013 Wish these wheel sellers would just use the term: BACK SPACING instead of offset. It sure muddies the water. Thanks madkaw. Quote Link to comment Share on other sites More sharing options...
74_5.0L_Z Posted May 10, 2013 Share Posted May 10, 2013 I agree! Offset is a relative term that is specific to the centerline of whatever width wheel you have. Backspace however is an absolute value that is independent of wheel width. Once I find a backspace that clears my struts, I can then vary the width to clear the fenders.

RebekahsZ Posted May 10, 2013 Author Share Posted May 10, 2013 An additional variable that frustrates things is the sidewall/bead design and "shoulder" of the tire. These variables make it almost impossible to answer the question often posted: "Will such-and-such tire fit my car?" For example, my cheap Khumos come straight up from the rim and roll gradually toward the center of the tread. On the same size tire, the Hoosiers project laterally from the lip of the rim a good 3/8" before going almost straight up to a very square shoulder. My tire guy calls that lateral thickness a "rim saver." Basically it is just a super thick sidewall starting from the mounting bead. Whether it is 100% true, I'm gonna personally operate as though the 245/45/16 or 17 is the widest thing I can fit on my car (understand that my car is lowered and the tire must fit INSIDE the fender) using 8" rims. I now have 9.5" of sticky tread on the ground-that's just gonna have to be enough. I just scored a used set of Hoosier A6s on ebay for $380 delivered. Project done-now I can move onto the next project. Quote Link to comment Share on other sites More sharing options...
