will there be any issues like rubbing, etc in putting on a 15x10 rim with 5" backspacing on a 2" lift?

Swirlchaser

I would imagine lots of rubbing. Stock wheels are 7" and I believe 5.25 BS.

i gotcha so would 3" backspacing be better or worse? Im clueless when it comes to wheels lol

Isn't it bad to have 0 or positive offset? Its harder on the bearings right? For some reason I keep thinking that in a bad situation like coming down real hard on one wheel or all 4 would shear the lug studs right off.

Either that or I had a dream like that... kinda like dreaming your teeth are falling out haha

The less the back spacing the further the wheel will stick out. To avoid rubbing the lower control arms and leaf springs with wider rims you want less backspace.

so should i be ok runnin 3" backspacing on a 10" rim?

Well that depends on the wheels width. But no it shouldnt be any rougher than a normal wheel. Offset is the distance measure from the center of the wheel to the wheel mounting surface. Backspacing is the distance measured from the edge of the wheel to the mounting surface. Having a 0 OFFSET would actually be better for your bearings than most any other wheel, as not many have an offset of 0.

Then why do stock wheels have an offset value? I thought the idea was that the centerline of the wheel would be coincident with the centerline of the bearing, theoretically placing the load evenly on the bearing. Having a 0 offset or more would move the centerline further away from the bearing, increasing the leverage of the weight and causing a distorted load on said bearing.

I know this is for a completely different application but I think it still applies.

All wheels have an offset and backspacing value. They're two ways of measuring where the wheels mounting surface is, and both are used because each have a different use. Having a zero offset (or 5" of backspacing on a 15x10 wheel) will place the mounting surface of the wheel directly in the center of the wheel, putting no extra leverage on the bearings. However, with that said, any leverage from having a wheel with an offset will be minimal at best. I have 3 1/2" backspacing on my wheels and yes the bearings are going out, however this will probably be the first time they've been replaced in the vehicles 150k of life and 18 years its been on the road.

Sorry, I meant a value as in greater or less than 0. I'm aware of the usage of backspacing and offset, tomato tomahto to describe the location of the wms in relation to the width of the wheel. I guess I also meant negative offset instead of positive, I did more research and realized a more positive offset will pull the wheels into the fenders more. I was hoping to find people who had issues with a 0 offset rim instead of realizing that a 15x8 wheel is more popular with 3.75" bs over 4" bs, which is what got me curious in the first place. Guess ill do 15x7's anyway

Question about the comanche.

87 MJ with the stock Dana 35, going to swap the 8.25 out of my 99 XJ into it and going to go to SOA setup. How much total lift will that be using a new set of stock size leafs?

I believe its about 4"

Getting ready to pull the trigger on an OME 2" lift install. Was originally going to buy 31x10.5 R15s for it. The guys at the shop said I might need to do a little fender trimming. Question: should I go with a slightly smaller tire if I want to avoid trimming anything? What's the smallest tire I could go with on 2" lift that wouldn't look like a roller skate? On an OME 2" lift with the 31x10.5 R15 will I have rubbing issues as long as I have wheels with proper backspacing?
Thanks in advance,
Cheers
