Need Help! 15x8 or 15x10?

Whats up fellas I am looking to place an order on a new set of wheels pretty soon. I have narrowed my choice down to some American Racing AR-23's. I am so undecided on what size I want to order. I have read that 15x8 are better for when you are looking to air down. However I like the wide look on 15x10s. I like how wheels look sticking out passed the flares and isnt an issue in Texas. I am running a 33x12.5x15 tire. My Jeep is my daily driver. And to be quiet honest I do not take my jeep off road much. If I do it would be on sand since we have a beach about an hour away. I have done some research and have found that either size weigh 25lbs. What do you guys think? My Jeep currently sits on Weld Rock Crushers (up for sale) and a 4" sky jacker lift.

If anyone has pics of a 15x10 wheel with 33x12.5x15 post pics!

Thanks for the help in advance!

Here is a pic of the wheel (backspacing would be 3.75 on either size)


Here is my rig

15x8 is the only wheel I'll ever run on a 12.5" tire. A: An 8" wheel is much better for airing down. B: I actually much prefer the look of an 8" wheel.

With that said, if you never go off road, never air down, and prefer the look of a 10" wheel, then that's what you should run.

I've aired down twice now on 10" wheels with no issues...

Twice isn't a lot of times.

I'd go 8" wide as well.

More than never like he said. I agree an 8" is better, but that doesn't mean a 10" won't still work.

You can air down on a 10" wheel, but you can air down further with less chance of loosing a bead on an 8" wheel.

what is aired down to you????? Unless we are talking 12psi and under. I see people aired down to 15-20 they Tinkk its aired down.

a few ways to look at this and what happens. a 33 12.5 is not the same as the 35x12.5 in they way the 8" rim "pinches the rim on a 15. You have less tire to make up the pinch to get a flat wear patter on road so your Highway use will be far less psi than on a 10" rim.

Aired down on 35x12.5x15 on 15"s for me is 9si for rock crawling day runs. On longer wheeling trips, Rubicon, Dusy etc. where we are days on the rail and loaded down like the Oregon trail peoples. about 12 psi for the wieght. 10" rims OFF road on therocks the bead of rim sticks out much to far and is the target of every boulder.

each has a use and each has advantage and less advatage

Was also gonna say that ^ first time was 12, second was 16 because I didn't need to be any lower.

I have had the chance to air down more than a couple, Most likely in over a thousand, And I have ran both in 8" and 10" in both steel and alloys many times.

To me, 5-8 psi is airing down. 8 is minimum for me to gain and advantage. Either way, You said you don't go off much and sand is the only thing. The 10" will give you the wider foot print and you will most likely never have to air down at the beach. I ran 10" in moab and had no problems on the rock or sand there.
On road, It will have a more responsive steering and tighter feel. But it will also make you're tires if m/t's, Louder from the larger gap of the wheel. Little bit more of a rougher ride, But can be fixed with lower DD psi/chalk test.

8" is what I currently run with 3.5" of BS and its perfect IMO. The wider look is there, But still tight enough on trail. No adjustments to the steering stops so I have full turning radius with no rubbing level or flexed. The tire rides a lot smoother down the road along with being a lot quieter with only a 8" gap. Plus you always have the option to drop to 8psi if wanted.

Long run if you go to sell them, 8" will sell faster than a 10", More so with a lighter wheel. Balance a lot better and easier with less weight IMO. But the 10" offers more aggressive DD driving if you drive in that type of traffic.

To each their own, That's the best way I can describe DD both 100+ mile round trip for many years on many tire combo's. It really comes down to what you want, You're money. Good luck either way.

If you want a pic of the current 8" with 3.5" BS, Ill have to take some. But all the 10" wheel does, Is stretch the sidewall, The 12.50 width is still just as wide and sticks out just as far.
