You are the man... that is exactly what I was thinking... I wanted to hear it from a 'pro'. Thanks

So what you are saying is that aired down tires are harder to puncture, except when they aren't.






Just busting your chops, I agree with you on this one, you trade durability in one area of the tire for another...

Triple88a There are 2 good things i can think of to air down too. First reason is traction and 2nd reason is punctures. Aired down tire is a lot harder to be punctured by a rock (unless it slices the sidewall)

I am looking for some technical information and experience here. I really want to make an educated choice.

MoA for example.. procomp mts for a 15'' rim are like 30 bucks cheaper PER tire than for a 16'' rim..

16'' tires arent much of a difference.. but when you get into 17-20'' tires.. then your getting into less of a sidewall.. which means the less you can air down.

like some one up above said.. most of us are using our jeeps for offroad purposes.. so a 15x8 tire is what MOST of us run.. who wants bling on a jeep anyways.. dont get me wrong, my next vehicle is going to have 20-22'' rims unless i get a truck.. but why would you put them on a jeep?

sounds like you really want 16'' wheels.. if you like it then buy it.. wo cares what anyone thinks.. they look nice.. but many here are or want to be hardcore crawlers.. I got 15'' wheels because there are more tires available and are cheaper than 16''. plus its also lighter since I cant afford alloy wheels.

I have steelies. 400th post yesss!!!!!

Here are my 35x12.5R15 with the 15x10 outlaw IIs

04-24-2008 12:01 AM
AzTJ A tire for a 15" wheel is cheaper... and I don't want to buy new wheels. Plus I think the same way Jerry does. A 15" wheel with a 35x12.5" tire is perfect.

debruins 15, cause its just easier and cheaper than buying 16's, and u might as well
04-23-2008 11:55 PM
Gilez OK Cool but why??
04-23-2008 11:53 PM
AzTJ When I go to 35's I'm gonna be keeping my 15's.

Ok ... so ... with 35's would you run 15 or 16?? Thanks

A tire requires less air pressure to remain safely seated against an 8" wide wheel than it does a 10" wide wheel.

15x10 is fine for a street Jeep if the tires are no smaller than around 32x11.50, but 15x8 is better for most common tire sizes for an offroad Jeep, at least up to a 35x12.50 size. I air my 35x12.50 tires mounted on 15x8 wheels down to 7 to 8 psi without any problems, but I couldn't air down even close to that much if I were using 15x10 wheels.

One thing to keep in mind that some don't understand... the wheel width is not selected to match a tire width, it is selected to match the tire's natural bead width. A 12.5" wide tire's natural bead width is closer to 8-9" than it is 10" apart. For example, running a 15x10 wheel would be a big mistake for a 31x10.50 size tire, especially since it would have a heck of a time staying seated if aired down even a little.
Thanks for the helpful info. So if you decided on the 8" width what about the rim size. What would be the reason to go with a 15 instead of a 17 with a 35" tire??? Thanks again.

MoA agreed.. look how the bulge out..

Yep, those wheels are simply too wide for that tire size.

he's in germany btw.. talk to nico about how bad the vehicle laws are.. my gma was explaining them to me years ago..


also i agree with jerry.. 15x8s are perfect for a jeep up to 35'' tires.. with a 3.75'' backspacing.. i wrapped mine with 33x12.5 pc mts



my gfs dad runs 15x10s and they are just TOO wide looking

17s are worthless unless you are running 42s or something outrageous like that. If you're running 33s with 17" wheels, your tires will get slashed, especially in Jersey. Thats just lame...you might as well be running 22" chrome spinners.

jbone03 AmericanRacing Outlaw II wheels in 15x10. Thats what I have! I love them but all the salt they put on the roads here in Germany caused the clear coat to peel. The only problem I have is the rims are 15x10.5 and the tires are 31-10.50 15 so if I want to air down the tires to go wheeling they will probably come off the rims. Also the back space is not enough so the tire sick out past the 6" fender flairs. Vehicle inspection didn't like that.
04-23-2008 12:11 PM
Gilez OK cool. Why not 17"??
04-23-2008 12:01 PM
[TheYJGuy] I'd buy the AmericanRacing Outlaw II wheels in 15x10, like Trip has.

They look sweet.

Rim Size

What are the advantages to the different rim sizes available. If you could have any size regardless of price, what size would you go with??
