Question About Wheel and Tires Fitment

Ok so I have a 1998 Wrangler with the 2.5l. I have stock Grizzly wheels and 31x10.50 tires. They rub a little bit on the frame when I make a sharp turn. I was wondering, if I got a new set of wheels with different backspacing would that cure the rubbing issue? If so, what backspacing would I need?

I would go with a 15x8 rim with 3.75 back spacing. This will also allow you to run a 12.50 wide tire down the road if you want.

Ok awesome. With 3.75 back spacing the tire will be stuck out farther. Correct?

It takes two five cent washers and ten minutes to fix that. Go to Jeep Steer Stop Adjustment

Wheel backspacing is the distance between the rear-most edge of the wheel and the wheel's mounting surface. The yellow tape measure in the below photo is measuring how much backspacing the wheel has. The more backspacing a wheel has, the further into the wheel well the wheel is positioned.

Thanks!! I'll do that soon (and probably still get new wheels)

You won't need those washers with new aftermarket wheels.

Your wheels will stick out unnecessarily far with only 3.5" of BS. The minimum I'd run is 3.75" with 4" being even better.

I have them with 33 12.50 15 DuraTracs Rating C and they fit OK. I wish they were 3.75 or 4.0 BS instead of 3.5 BS, but they are fine !! Pricing on this wheel has been substantially lowered since Ion came out with new designs..........tough to beat.

So, is the above photo "Ion Alloy 174 Black Beadlock Wheel (15x8"/5x114.3mm)" is that you have? Is that the correct size for a TJ (5 x 4.5") I find them on Amazon for only $110 and that includes shipping. I see it is only a 3.5" backspacing - but a 1" spacer would resolve that.

Adding a 1" spacer would give that wheel with 3.5" of backspacing the equivilent of 2.5" of backspacing. A spacer positions the wheel further out of the wheel well, not further in.

Would 4 inch back spacing be enough to not rub. Because I would rather them not stick out as much as possible if that makes sense.

4" of backspacing would be fine, anything between that and 5" would work fine for your 31x10.50 tires.

Nice jeep man. Those wheels look really good. I might just pull the trigger. They're only like 89.99 a piece from quadratec.

helmsy,
you can get free shipping by going to google and type in "174-5865B quadtratec", then click on the "shopping" option, then click the link that pops up and you will see free shipping when you add it to your cart......

Other than the tires sticking out farther than really necessary are there any ill effects to having 3.5 inch backspacing?

It is only 1/2" difference; Mostly unnoticed in the scheme of things. Some say it is harder on the bearings, whereas harder is an ambiguous term. In doing the B10 bearing life calculations, which I have actually done, the extra load of increasing the moment-arm by 1/2" is truly insignificant. The biggest negative to me is throwing mud all over the side of the Jeep !!

Awesome explanation and I actually understood it (thank you college physics).I was mostly concerned about it being harder on the bearings and that is exactly what I wanted to hear.
I don't think I can wait till spring like I was planning to...I'm ordering them next week...

Just a little caveat...........It works for any online shipping vendor. The trick is to use the OEM part number then the vendor you wish to purchase from. You cannot use the vendor number, it has to be the manufactures number. The flaw in the program is after you choose just one item and put it in your cart, you can add anything else from the vendors website and the shipping will remain free for all items..........if you buy a light bulb from QT for $1.99, then add a $1000.00, 500 pound bumper, the shipping is still free.....
