Thank you for the additional clarification, I was getting mixed information between here and elsewhere but you certainly are more convincing and you are right, that photo should have answered my question. Sounds like I'll be sticking with the stock wheels, now I just have to pick out my tires.
[quote name="EagleYou have already been shown that 31x10.50s will fit the stock suspension. They will ... with stock 15x7 Jeep rims. They WILL rub the lower control arms at full steering lock ... so will 30x9.50s. You either adjust the steering stops' date=' or live with it.
Backspacing on the Jeep rims is 5-1/4". There are NO aftermarket 15x8 rims that offer that backspacing. If you use aftermarket rims, the tires WILL extend farther out from the vehicle centerline. This is a problem. On the stock rims, 31x10.50s will tuck up (just barely) inside the stock flares when the front suspension is compressed. If you use rims with less backspacing (even 15x7), the tires will hit the flares and rip them apart in short order. This will continue to be the case even after lifting, BTW, unless you extend the bump stops. That solves the problem of hitting the flares -- but you lose suspension travel, so what's the point?
In the rear, 31x10.50s will fit on Jeep rims and will tuck inside the flares. They ride VERY close to the frame, and when the suspension gets twisted up you see marks where the top of the tire rubs the inside of the wheelwell. A bit less backspacing would help that, but then you're back to hitting the flares. Running 30x9.50s gains an extra half inch of clearance there. I just ran the 31s and accepted the occasional rubbing. It didn't seem to hurt anything.[/quote]
