35's on stock 15x7's?

[scotts90ranger]

is this a bad idea? I have a chance to get a set of 35x12.50 BFG MT's for $700, I have stock aluminum 15x7 wheels, would finding a set of 15x8's be a huge difference? I kinda like the look of the wheels I have, and finding wheels is harder than I thought...

you can run them a bunch of people do just have to run a little less air pressure so they wear correctly

 

[Fx4wannabe01]

You can but I wouldn't. Rule of thumb is 4" difference max.


New 15x10 steelies run about $60 ea brand new. 15x8's are about $45 ea brand new.

You'll be fine for a bit. It will accelerate the wear on the center of the tire tread.

I would be looking for some 15x8's with 3.75" backspacing tho.

A 7" wheel isn't exactly ideal for a 12.5" tire. I agree that the minimum should be 8", with a backspacing that will push them to the outsides a bit more.

im running a 12.50" on a 7" wide rim and have done so for years without any problems im running 30psi in all 4 and they wear beautifully just make sure to rotate every 3000 miles or so and you will be fine

no you dont, im running 12.50 on a 7" wide rim with no problems, i know several people that also run the same setup and no issues, so NO you do not have to, its personal preference and thats what it comes down to

I've been running 33x12.5's on stock 15x7's for a while now. Works like a champ, but yes air 'em down a little to get better wear. PLUS, I've run them snow wheeling with like 2 psi, and haven't blown a bead even. Awesome.

 

[Original_Ranger84]

Well there is a difference in sidewall height too between 33x12.50's and 35x12.50's with a 35 you have more side wall that can fit on a narrower rim, so with a 33 and an 8 in rim you can run a 35 on a 7 in rim just fine i would think.

I know some shops won't mount up a tire that isn't on the reccommended rim width. I think that's what he's getting at.

Some shops won't mount up tires over 8 years old either. So that means no BFG Radial Mud Terrains.

you can run 12.5's on a 7" rim. ive done it before and hod no problem other than some slight rubbing at full turn. 11.5's however didnt produce the same rub. I currently run 35 12.5 on the front and 35 14.5 on the rear and have no trouble with the front. however the rear do buldge some and i had to make 1.5" spacers to get the rear off my leafs
