Hey Guys lil help.
I am looking to get 35x12.50-16 tires and want to know what rim width I should go with. I want to go with the 10" wide. Is there a reason why I should not as far as airing down goes? With a 5.5" lift would I have any rubbing issues with 4.5" back spacing on either the 8" or 10" wide wheels?
Please throw out any ideas or comments you might have.
Pictures would be nice too.

Thanks for your help.

Personally I would go with 10" wide. I've had both 8" wide and 10" wide on mine and I think it handles a lot better with the 8" wide wheels. Plus as you stated you can safley air down more on the 8" wide.

Some guys would say to go with the 16 X 8 wheel to hold a bead better when aired down, and help protect the rims from rocks. That idea has merit, especially if you're a rock crawler. This can be aired down very much for rock crawling. I think this could be aired down to 10 or 12 psi without a bead lock and still hold a bead (probably). Personally, I seldom air down below 18 psi, and never below 15 psi. I'm not a rockcrawler. So I have no need to air down below 15 psi. Are you a rock crawler?

Other guys would say to go with the 16 X 10 wheel to give a wide tire better support and a flatter footprint at street pressures and better street driving (I assume you want to drive on street too?). That idea has merit, especially if you're not a rock crawler. I'm sure it could be aired down safely to 15 or 18 psi with no fear of losing a bead. I've heard this combo cannot be aired down to single digits because of losing a bead. Well, that's not a concern to me since I seldom air down below 18 psi, and never below 15 psi. I think 16 X 10 would be preferable, if you're not a rock crawler wanting to air down to single digit psi.

Of those two choices, I'd go with the 16 X 10 wheel.

However, I think a 16 X 9 wheel would be the best choice, if you can find one. It's not a common size wheel, but I've seen a couple of them at a couple manufacturers in the past.

Moto Metal makes a couple of nice 16 X 9 wheel with 4.5" backspacing.

That's my opinion.

Here is a link to a Moto Metal SUV/Truck wheel that is 16 X 9, 5 on 4.5 bolt pattern, with 4.5" backspacing.

With the combination of a 9" wide wheel and 4.5" of backspacing, you should have tire moved out 1.5" compared to a stock Wrangler 15 X 8 Rim, or moved out 1" compared to a stock Rubi Moab 16 X 8 rim. That's because the rim widths and the backspacing both affect tire clearance to swaybar and LCA.

By my calculations, that should be a perfect fit for 33 X 12.5 tires and swaybar/LCA clearance when turning hard left or right. i.e. - I think this would fit perfect with no need to adjust steer stops to reduce turning radius.

If it did rub sway bar, then get an aftermarket swaybar that has more tire clearance that stock swaybar. If it did rub LCAs, then get some rounded LCAs (like JKS brand of LCA for example). Once that's done it for sure wouldn't rub swaybar or LCAs.

By my calculations this wheel would be perfect for fitting a 33 X 12.5 R16 tire on an XJ/TJ/LJ.

It'd also be nice for the 33 X 11.5 R16 (285/75R16) tires on my LJ to give me a flat footprint at a higher tire pressure when I'm onroad, and I could still air down to 12 to 15 psi for offroad without losing a bead. Though normally I'd only air down to 18 psi for my offroad needs.

Those are said to be study offroad capable SUV/truck rims, according to my local tire store that has sold many, and also according to some online reviews I read. These are the only 16 X 9 wheels I've ever seen in a 5 on 4.5 bolt pattern.

Axis wheels also makes a nice 16 X 9 wheel, but not in a bolt pattern that fits on a Jeep.

Those are the only 16 X 9 wheels I've ever seen, and only the Moto Metel model 951 has the bolt pattern to fit an XJ/TJ.

So there is a quality 16 X 9 wheel available for you, but only one that I know of. I spent a lot of time looking for 16 X 9 wheels in the past. I'm fairly sure this is the only one made by anyone that fits a Jeep. The good news is that since it has a pseudo (fake) beadlock look. So it's rim lip is probably extra strong because of it. I read in one of the 4x4 magazines that the beadlock look wheels (fake beadlock) have a wheel rim/lip that is thicker, stronger, and more resistant to damage. Also, it's less likely you'd hit the wheel on an obstacle because you'd have a 12.5" tire that's a lot wider than the wheel.

Thanks for the great info and opinions. I actually thought the 10" rim would hold a better bead. Guess I thought wrong on that one.

I am a rock crawler, but also do some street driving. This jeep will mostly see the street going to the trails, and hopefully see it coming back too.

Thanks again for all you help.

Rubber side down guys.

what sort of driving do you do ?
are you fitting bias or radial tires ?
are you going to be using bead locks ?
what tire are you using ?
alloy or steel wheels ?

[WKENDWARIOR69]

Most of the driving will me rock crawling such as Moab, or the Rubicon.
I have not figured out if it will be bias or radial, does that matter much? For Bias I was going with Maxxis Creepy, Radial would be BFG KX Krawlers, or Goodyear MTRs
I was not planning on using bead locks.

I currently have a set of 35x12.5s that I recently picked up lightly used. They came with 10" rims. I picked up 5 Pro Comp 15x8s to change them out. I had a couple of reasons,

1. The 10" rims have the same 3.75" BS that the 8" rims have this sticks the outside of the tires out farther, puts more stress on the unit-bearings and puts (slightly) more stress on the already marginal steering. If you find 4.5" BS this may mitigate this a bit but 8" with 4.5 would still be less stress than 10" with 4.5" BS.

2. Airing down, kind of a mixed bag on this. The 8" will hold a bead better but the wider 10" may let the tire wrap around rocks better with a higher pressure so that may be a wash.

Main reason was the stress on components.

Bottom line is it's your Jeep, do what works for you. We all wheel in different surroundings and conditions what works for me (mountains of CO and Moab) may not work for you.

if using the maxxis creepy crawler use a 10 inch wide wheel other wise
it will crown excessively and wear in the centre these are awsome tyres
for rock and also perform ok in mud .
the goodyear mtr would be 315/75r16 these are ok on either 8 or 10 inch
wide wheel .
as for the kx krawler these are only available in 15 or 17 inch fitment
as far as i know .
