Jeep sahara 8 inch Canyon wheels fit and look great on a cherokee,
I have had two different cherokees and used canyon wheels on both
you can fit 30/9:50/15 A/T tires under a stock height cherokee using these wheels.
A 235 and a 30/9:50/15 is very close to same height.
if you use a stock 8 inch jeep wheel it keeps the back spacing where it should be. if you use a aftermarket wheel with alot of offset , moldings will rub when the body rolls and dips.
I made that mistake on one cherokee, using black steel slotted wheels with alot of back spacing and it stuck the wheel further out to the edge of the fender and looked good but the rear rubbed when hitting bumps or when body rolled.
8 inch jeep wrangler sahara canyon wheels are about the best looking wheel from the factory.
I dont know about most of the newer jeeps but any tj wrangler up to 2006 will have 5 on 4.5 pattern and any grand cherokee up to 1998. The newer jk wranglers i believe are 5 on 5 or 5 on 5.5 and i dont know about the newer grand cherokees.
The Grand's bolt pattern changed in 99 so only up to 98 for wheels to fit a Cherokee. Wrangler till the new style came out I think in 07. A lot of parts are very similar from the ZJ to the XJ, brake rotors, calipers, etc.
