Different tire size front and rear = damage??
So my wife had a blowout last night. Only spare is the factory donut. Unable to get just one replacement tire or even a full new set locally intil Monday afternoon. Currently tires are 225-75-15. I have 8 235-75 and was going to put just 2 on the rear for the weekend. Fronts are spec'd at 28.3 inches new. The 235's are 28.9 inches new. The fronts are nearly bald and probably only about 28 currently and the 235 are half worn and likely about 28.5 or less right now. So question is how much damage would I do running tires that are half an inch taller in the rear? Both diffs are open and t-case is the 231. Will not be using 4x4 at all. I could switch all 4 over to the 235 if I really need to but we had plans this morning and the quicker I do this the better off we will be. Thanks everyone for the input.

That's what I was hoping but I've always made sure my tires were correct so I don't have any experience to go off. Also with the Jeep at 210,000 I wasn't sure if that would make chances of breakage greater. The biggest concern is having to get the Jeep towed 40 miles to my house or something. That would just add to what I already can't afford.

I agree... It won't do any damage as long as you don't put it in 4X4. But this is one of those times when having locking front hubs would come in handy. Then you would know for sure the front wheels are completely unhooked from the drive train.

I look at it this way. If you're blowing donuts in mud or snow or just or something like that then the rear wheels are moving a heck of a lot faster that the fronts and that I have some experience with. Never did any damage then. So I don't think it would cause much of an issue under normal circumstances.

You will be fine in 2wd. In 4wd the tires will bind on the concrete, and something will eventually give (axle shaft / gear / transfer case).
I test drove an xj with 4 different sized tires last year. To no surprise the front gears were hamburgered.
