Wheel fitment specs
The 2007 Jeep Grand Cherokee uses a 5x127 bolt pattern with a 71.5mm hub bore. Safe rim width range for the OEM tire is 8.5J â 9.5J, and offsets in the ET30 â ET40 window will clear suspension and fender without rubbing on most setups.
Staggered setup notes
The 2007 Jeep Grand Cherokee ships staggered: 255/45R20 up front and 285/40R20 on the rear. That is a 285mm vs 255mm width difference â do not rotate front-to-rear, and replace tires in axle pairs to keep ABS and traction control balanced.
Tire pressure guidance
Manufacturer-recommended cold tire pressure for the 2007 Jeep Grand Cherokee is printed on the driver-side door jamb sticker â always defer to that value, not to the maximum pressure printed on the tire sidewall. Check pressure monthly and before long trips; under-inflation by 20% can reduce tread life by 25%.
