It depends on your wheel offset. I have 8" Lift and 37s and they will sometimes rub

Not sure what the offset or backspacing is, I will have to get back and pop one of them off to check. Also, if I crank up the torsion bars in the front, wont it ride like hell?

I see you have 8", I assume the rubbing is due primarily to width?

Also what trimming did you do?

What brand of rim are they?? you should be able to find backspace on there website.

On a NNBS truck its much ahrder to fit 37s, so dont take SmoknLBZ's post into account as he has a nbs which is way easier to stuff.

Ur backsapce will probably be the same if not more than mine on 22x12's, so they will work, but you will need to do the NorCal Fender Mod, and tie the front of the plastic liner back

If you crank to 8" you will suffer a bit in ride, but not that much as long as you have some good shocks ie bilstein, fox, king

im gonna be installing 37x12.50x17 coopers on a 6in zone lift. backspacing is everything. im going with a 17x9 with a -12mm offset. it should work nice. i dont plan to beat my truck offroad, so there will be some trimming needed, but it'll stay onroad 99.9% of the time.

like everyone said, i think it depends on the wheel width and offset/backspacing.

Check my math.... 17x9 -12 is 4.5" of backspace right?
((9+1)/2)-.5 = 4.5"


Also what is a nnbs truck vs nbs?

Also I found the norcal fender mod sticky but it looks like the pics are not there anymore.... bummer. Is there another site with the pics?
