15x8 vs 15x10...?

Just got my 06 TJ 3 weeks ago and while it's nice in stock form, I know it's not going to stay that way. As I'm planning my mods, of course the thought goes to wheels and tires. It will serve as my daily driver for a while, so I'll probably hold out on a lift for now. From what I've been reading on the forum, that would make 31" tires the largest I'd be able to run on the stock suspension.

My question is for the wheels, concerning 15x8 vs 15x10... I love the look of a wide stance and I don't really believe tires can stick out too far on a jeep. I'm also planning on getting some wider fender flares, 6"-7", maybe the Bushwhackers, haven't decided just yet.

For the purposes of being a DD, driving through the Chicago snow, and perhaps some LIGHT off roading for now, what differences could I expect from the different widths of wheels? I get that the wider wheels will be heavier which will affect gas mileage, and there's the back spacing issue. What else should I know before deciding on them?

10" wide rims really are too wide for a 10.50" tire. It'd be easy to pop the bead. An 8" rim is ideal for up to a 12.5" wide tire.

Agreed...as said above, 8" rim up to 12.5" tire then 10" wide with 13.5+

Ok, and what can I expect from those differences? Pro's and cons if you will...

Any kind of rubbing issues, back spacing causing any problems with additional stress to other components, gearing issues due to additional weight of the wider wheels & tires, etc...

Thanks

Pros of 8": Can air down farther without blowing the bead, balloons the tire for a softer ride (at least I think so), and lighter weight.

Cons: None I can think of.

Pros of 10": can run a 13"+ wide tire later

Cons: heavier, can't air down as far

As far as backspacing goes, you can choose that. On a TJ, I'd go with a 15x8 with 3.75"-4" backspacing. You wouldn't have any rubbing problems

Just run your stock rims. 31s will fit nicely even on 7" rims

I want to upgrade to some black wheels (tj is yellow)

How would a set of 31" tires be able to handle a switch from a 15x7 to a 15x8 wheel if I got the tires first? I assume I'd be restricted on the width of tire I could fit on the stock rim. Any other issues to potentially deal with?

The switch would be fine, but if you can handle the wait, I'd wait to put the tires on till you get the rims you want. Then you don't have to pay for mounting and balancing twice.

Yeah, that's what I'm leaning towards. I'm a patient man. I was just curious since using the stock rims was mentioned earlier.

The stock rims will work until you get your new rims.

Very well said. 15x8 with that back-spacing is what most of the experienced Forum members would recommend.
