33's on stock rims, enough backspacing?
 
If i run a 3 inch lift with 33s on stock rims, will they rub with the 5inch deep backspacing? if so how bad, will it rub at full turn? thanks :help:

I've seen 33x9.5's on stock rims. Looked good without any rub. 33x12'...not so much.

33x12.50 tires will rub the inside sidewalls with factory wheels. You'll have to find a 33x9.50 or 33x10.50 if you want to mount them on the stock wheels without installing wheel spacers.

my friend gave me a set of BFG MTR-KM for free but theyre 33x12.50, how much will they rub? how much backspacing would be needed to avoid rubbing?

I just put on 33x12.5 on a 3.25" lift on soft 8s with 4" backspacing and yes, they rub -

I just put 1.5" spacers on and no more rub, looking at wheels you will probably be stuck with 2.5" bs, 3.75" bs wont be enough. With the spacers theres no rubbing at all, but they do still hit the fenders unless you change your bump stops.

yeh i think im gunna get the bushwacker flat style fender flares so thats an extra 2.5 inches of clearence so that should do the trick for the fender rub.

I run 33x12.5 on wheels with 3.75" backspacing and I don't believe I have any rubbing issues at all.

1. fender flares don't increase your tire clearance. do some research on bumpstop extensions.
2. your 2" lift alone isn't enough for 33s. do some research on bumpstop extensions.
3. 33x12.50R15 on stock rims w/o wheel spacers will not only rub the control arms in front, but the sidewalls will rub the rear spring perch and you won't make it far before the tire is cut apart.

X2 on the above and you don't want more backspacing, you want less. Your factory wheels have around 5.25" to 5.5" of backspacing which is too much for a 12.5" wide tire. You need a wheel with between 3.75" and 4.5" of backspacing.

I have 33x10.5x15 BFG All Terrain with my stock steel rims and they don't rub.

LJ, 2 in BDS suspension lift (with appropriate bumpstop extensions), running 33x10.5 BFG All Terrains on stock wheels. Front tires contact the control arms at full turn. In the rear, there is about a fingers width of clearance (.5 in. give or take some) between the tire and the coil perch. For the street, I'm comfortable with this set up, I'm just conscious of the issue when parking (avoiding excessive amounts of tight maneuvers). I'm thinking that I will adding 1.25" spacers to give me a little bit more clearance and peace of mind.

4" lift with 33x10.50's on Canyon wheels. I get some rubbing at full lock, but otherwise they are fine.

'06 LJ, V8 ZJ springs in front(2.25" lift) and 1.75" spacers in back, 33x12.50 on the stock ravine rims with 1.25" wheel spacers. as long as the swaybar is hooked up i get no rubbing at all.

Dont just say "wrong" back it up, tell us why its wrong, give us the benefit of your wisdom instead of your judgement.

I know what I have, and I know what doesnt work because I have done it. If you have had a different experiance, tell us about it, tell us what size tires you had, tell us what backspacing you had, tell us what lift you had, tell us how it worked or didnt.

Just saying "wrong" is a waste of your time and ours boggieman, but it helps your post count, so, I guess it works for you (lazy though).
