Before Replacing Tires
- Read the full size, load index, and speed rating on the door placard and current tire. Performance models may specify a ZR-rated tire.
- Follow the owner’s manual for cold inflation pressure and replacement tire requirements; do not use the maximum pressure molded on the tire as the vehicle setting.
- On 4WD/AWD models, follow Jeep’s guidance for matching tires and allowable tread-depth differences; mismatched rolling circumference can affect driveline components.
- Confirm wheel diameter and brake clearance before changing wheel or tire size. A size listed for another trim is not automatically an approved replacement.
See the 2019 Jeep Grand Cherokee specifications for factory applications and the Mopar User Guide for tire placard and maintenance information. Goodyear’s trim lookup can help cross-check a trim, but the vehicle placard remains the final reference.
