rim back spacing question
 
Hello there every one i have a 03 TJ im currently waiting on the 4inch lift kit and was wanting to know if i will have any tire rub issues with a 4inch back space with a set of 33talls by 12.5 wides?

You might have very slight tire rub on the lower control arm. But I think you might be alright. Anything more than 4 and you would for sure.

You should be good...I had 14"wides on a 3.75 backspace with NO PROBLEMS. I could flex the tires right up to the fender flares and never had any rub except for the flare itself....(forgot the bumpstops) so 12.5 on a 4" should be good....

4" is ideal, I'd run that backspace for my 12.5" wide tires every day any day.

Ok good because when I called to order the tire and rim package they said it SOULD be fine and I said if you can't tell me 100% I'm not going to have rubbing issues I'm not going to spend over a grand on a should be statement

Now how's the turning effected by that wide of a tire?

Didn't realize you were in Illinois. Are you in an area that sees much snow? Be prepared for how your Jeep is going to handle slush and deep snow on the roads. You will be all over the place. Unless you have already been driving on 12.5's. I don't think turning will be affected to much. It might be slightly wider though.

Nope but I love to power slide when it rains and also love parking on big packed mounds of snow from the plows

jeepdude2003 12-16-2011 09:58 AM

Got to love the torque of the inline six on a five speed down the road I want go from 307gears to 410s

Tire width doesn't affect your turning radius.

Rubicon2 12-16-2011 11:55 AM

Jerry's right. The only time turning radius would be affected would be with more backspacing on the wheels.

I'd stick with the 8 inch rim either way. I have my 33x12.5 on 10" wheels and my buddy has the same tires on his stock 8" canyon wheels, and I think his look better. Also if you air down your tires off-road, you can let a lot more air out with the 8" rims and not have to worry about loosing your bead....

If your going to stick with the bf km2's, I'd be careful in the snow on the roads....a friend of mine has them on his ranger, and it's all over the road on wet, and lightly covered snowy roads....But thier BOMB in the mud and trails....

Let's hope that 'one more good smoky burnout' doesn't snap an axleshaft, u-joint, or be the death knell for your clutch.
