33s are coming, will they fit?

The jeep is coming together, I got the lift on, the drive line vibrations figured out, the engine running like a champ, now it is tire time.

I love the new BFG mud terrain KMs, so I ordered up a set of 33X12.50. I need to know if they will rub because of my rims.

The rims I have a off an RV, they look exactly like the black "rock crawler" steel wheels everyone sells. They are 15x8s and I dont know the back spacing?

I only have 9.50s on the jeep now, so the jump to 12.50s is fairly major. Will the 12.50s fit on a cj with most rims. I am talking about the direction towards the jeep, nnot the fenders, I have that covered(I hope!).

What back spacing would I need to fit these tires?

How do I measure the backspacing of my current wheels?

If wont work, what about spacers, who sells them, how much do they cost? DO I need new lug nut studs? What are the disadvantages besides wider stance, if you consider that much of a disadvantage?
Any advice is good.

thanks,
tony

Re: 33s are coming, will they fit?

(Taken form JeepTech.com)
"Backspacing is the distance from the inside rim surface to the backside of the wheel mounting surface. It determines how far a wheel (& tire) sticks into or out of the wheel well of the vehicle. Wheels with a lot of backspacing will stick further in. Wheels with little back spacing will stick further out."

Re: 33s are coming, will they fit?

Since you have narrow track axles, you'll probably rub the sway bar, possible the springs. Easily fixed with different rims. Stay away from wheel spacers!

I'm boycotting sigs. If ya wanna see what I have, check my profile.

Re: 33s are coming, will they fit?

You need to run a wheel with approximately 3 1/2" backspace or they will rub your springs. Some wheel spacers are fine to use. I wouldn't use the cheap ones from Pep Boys but you can order some from Stage West that are machined and really nice. They bolt to your existing lugs then you bolt your wheel to the spacers lugs. They are about $160 per set of 2. I forget the URL for Stage West, but I'm sure you can find it. But they didn't have them listed on their site the last time I was their, so you have to e-mail them and ask. Spidertrax has them too, but I think Stage West has more widths available. Hope this helps. Later, Casey

Re: 33s are coming, will they fit?

thanks for all the info,

I wil measure my wheels to see if they are 3.5"

I dont have sway bars so that wont be a promblem, maybe the springs?

Spacers seem high priced, I could get a new set of wheels for slightly more?

thanks
tony
