Q? on tire fit due to tire width

[BuckHunt]

12.50's are wide - wont seem to fit a troop with stock wheels without rubbing.

Next set of tires i get i want a set of 34x10.50's

Do you all have any idea if a 10.50 would fit with stock wheels? If not, what type of backspacing would i need? I know jack squat about backspacing.

I have seen several troopers running around on 33x10.5's. Granted, most had some sort of lift, but the width was fine.

I think what it is that I'm concerned with is rubbing on turn. i have 285/75/16's on now, like a 32.8" tire. they do not rub any way. I am assuming they are around 10" wide or so, dont actually know.

I plan on trying the 34" tires whenever the time for new tires comes.
Would the extra inch in diameter make it possible for them to rub anywhere? Fenders, swaybars, etc?

If so, imagine the only route i could go would be aftermarket wheels with a little more backspacing to keep from rubbing any parts at full turn.

285s are 285 mm (or 28.5 cm) wide, you do the English unit conversion! Actually that's about 11.3"

AFAIK about the biggest you can go is 33" without trimming or body lift. Not sure if 33x12.5 will fit, but as mentioned about people are definitely running 33x10.5s. Of course you have to get 15" wheels to run those.

The width is the width, fellas.

When you're looking at a floatation tire width measurement, such as 10.50, you're looking at the section width, which is the width of the tire at the widest point, which is roughly halfway between the bead of the wheel and the outside of the tread.

So, a 10.50 is right around 10.5" wide at it's widest point, no matter what the height is.

I would think, especially on stock wheels, that a 34x10.50 should fit just fine, as long as the thing was lifted at least a couple inches.

Those pics of my Trooper with the 33s on it show what a stock height Trooper looks like with 33x12.50x15 mud terrains look like on a 15x8" wheel with 3.75" backspacing. Our stock wheels have a lot more backspacing, so they should tuck underneath more, thereby reducing the rub on the fender well.

That's not to say that it won't rub on your frame or top of your inner fenderwell when you're at full flex.

Cool... the backspacing stuff makes a bit more sense to me now.

I have umm... 3" lift up front... bout 2.5 in the rear... It looks like 34's would fit, i mean its not that big of a step up from 33's. in the case that it did rub, what should i read up on? Anyone have any good links? I've done searches for fender trimming on other boards, but i dont have the guts to sawzall my beloved. i've heard of something like a hairdryer blowing hot air to make the wheelwell more malleable and then beating it with a hammer to move it back a bit, does that sound plausible if i should encounter any wheelwell rubbing?

[IsuzuRS]

sounds like it would have to be one good hair dryer. I refuse to trim my fenders, i have no need since the 32" tires don't rub. I think using a torch, you could heat up the metal and make it more maliable, easier than with a hair dryier. if you do anything, let us know!!

What I'd do to avoid rub on 34s is extend my bumpstops. That way they don't have the option of rubbing, at least upward. A guy could probably also change where the steering reaches "full lock."

[BuckHunt]

Thanks for the suggestions all.

i dont even really want to go up from 33's that bad, but man, just that extra 1/2" of ground clearance and good looking MT tread would be a nice treat =)
I'm set on trying it next time i buy tires!
