Could anyone can tell me what the result would be of putting on wheels with a -12mm offset??

All other dimensions should work fine :

17x9
6 / 5.5 BP
4 1/2" backspacing


Thanks in advance

Offset is the opposite measurement from backspacing - they'll be fine but stick out more than the stockers.

15x8", 6 on 5.5 Bolt Pattern;BackSpacing = 4 in.;Offset = -12 mm - she is running 31x12.3 Pro Comp ATs and had to cut the back of the front wheel wells a bit....

A 9" wide rim is going to be tricky especially with tire widths above 31x10.50 - and even those will require twisting of the T-Bars AND some cutting of the rear of the front wheel well.

Tone-

Thank you very much sir;
Are you saying then that the/any 9" wide wheel (with tire) will require a lift and/or trimming?

I have had 20X9's on mine without any lift. Forget the bs and offset but there is no rubbing.

20x9's and no rubbing? I am kinda floored by that considering I have 18x8.5's and trimmed everything but my tonsils. It's all in tire size though. If you are running on rubber bands, that can make all the difference in the world. My 285/60's were hell on the cladding. I think my VX lost 5lbs from Clad-O-Suction.

They have Yoko AVS's 265/50. Not too rubber bandish. Look at my gallery. I HATE rubber bands on big rims, I really cant stand it.

Backspacing is the culprit - almost ALL aftermarket rims will sit farther out from the wheel hub. Add wider rubber and it gets worse. 20x9 certainly has rubber bands and the tbars turned up at least a little.

No T-Bar crank at all. I just have perfect BS on this wheel.
Stockers are only 29.57 while my 265-50-20 are 30.43. I lost a half inch in sidewall but gained almost a full inch in both overall diameter and width.
