255/75R17 on an 05 Grand Cherokee?

Time for new tires on my wifes Silver 05 Grand Cherokee Limited. We're keeping the stock wheels and don't want it to be too big, but I was thinking about upgrading to a 255/75R17. Does anybody have any pics of this setup? I'd like to skip a lift if possible.

Here's mine with a 2.5" lift:






I recommend a lift with these tires, they would be stuffed in there without one and I'd imagine they would rub every time you'd hit a bump. Hope these help!

Sounds a bit too much without a basic lift.

Also your ESP, Traction and Speedo would not work properly. I am not sure if you can get the system re-calibrated with the new size tyres.....

ESP and traction work fine, until all fours come off the ground over some train tracks

How bad is your rubbing? And do you know the wheel backspacing and offset?

There was a little rubbing on the inside of the fender well... nothing a little hammer couldn't handle . I didn't use any spacers, I upgraded wheels that are slightly offset.

I just put a set of 265/70/17 Cooper Stt's on my 05 cherokee with Rough Country 1 1/2 Wheel spacers. They rub in the front so I guess I will have to lift it eventually. I like the way it looks right now but I dont know how to fix the rubbing on the inside front fender. Any ideas?

I have seen some picture of a WK with Jeep Moab wheels running 255/75/17 bfg mud terrains, 1/4" spacers, no lift and he had very minor rubbing at full lock, not enough rubbing to do the pinch weld.

I guess it isn't not rubbing to bad, but today I took the inner liner out of the front fender well and took a sawzall and cut inch gashes and bent the pinch weld back just to make sure I dont cut a tire. How much of a difference is there between the 265/70/17 Stt I have on my car now compared to the 255/75/17 BFG mud terrains?

255/75 are a tad taller than your 265/70

265/70's are a tad wider than the 255/75

most rubbing is a result of wider tires though.. not taller. Although I specifically installed 255/75's to avoid wheel spacers and pinchweld mod's... the tires rubbed anyway, lol... I STILL ended up having to get spacers, lol.

That aint true...lol. ESP and Traction would work fine. Speedo would be off by about 5 MPH.

I have the 2.25" lift with the same tires...no issues with ESP or Traction.

Stick with 265/65-17's.. They ride much better and are only 1/2 inch shorter. I've had 265/65's and now 255/70's and I can honestly say that I cannot SEE the size difference but I FEEL the difference and I prefer the feel of the 265's.
