05 cherokee tire size

Will 2012 wrangler rims with 255 70 18 tires on them fit a 05 cherokee Laredo?

I assume you mean Grand Cherokee. With spacers, you can squeeze them on, BUT, the upper ball joint stud may rub and you will need to do the pinch seam mod or you will wear the inner fender liner at the rear. If you want to wheel it, your better option is 17" rims with 265-70-17 tires, almost the same height but more readily available.

Yup that's what I meant. New t this vehicle. I have 245/70/17 on it. I'm not looking to do any big modifications,not yet anyway. 245 75 17 is what I'm looking at now. Michelin defenders. I don't I'll have any issues with them.

If you go to a wider tire, be aware that the upper ball joint stud could rub the inside tread lugs. My rims are 17"x 9" with 4.75" backspace and 265-70-17 tires fit before I had the front pinch seam mod and the rear fender mod done. I now run 275-70-17 but will go to 285-70-17 next. The 245-75-17 is about the same height as the 265-70-17, but about an inch narrower, so you may be fine.

Thanks Larry. I was told the 245 75 17 was outside the manufacturer recommended 3% increase in size. I had no idea such a small increase from 245 70 17 could be an issue. The increase in diameter isn't that much... thanks for your input.

Stock on mine was 245-65-17 (29.5") so going to 245-75-17 (31.5") is about 6.75% increase which will affect your speedometer/odometer a bit. A Superchips tuner (FlashPaq or FlashCal) can compensate for the difference in tire size and bring your speedo back to normal.

As long as it doesn't mess with suspension and steering I'm good. I don't drive all that fast any way. I'll look into the chips...
