| Section width | 265 | Width of the tire in millimeters |
| Aspect ratio | 60 | Section height as a percent of section width |

From the 2026 Jeep Grand Cherokee owner's manual (Tire Safety Information: Tire Markings and Tire Sizing Chart), read November 4, 2026. The load index and speed symbol follow the size on the tire sidewall.
Replacing tires: what the manual says
Your vehicle's exact original-equipment tire size is on the Tire and Loading Information Placard on the driver's side B-pillar or the rear edge of the driver's door, or on the Vehicle Certification Label. The manual strongly recommends replacement tires equivalent to the originals in size, quality and performance, and warns not to use a tire, wheel size, load rating or speed rating other than the one specified for your vehicle.
It also recommends replacing the two front tires or the two rear tires as a pair, says tires and the spare tire should be replaced after six years regardless of remaining tread, and asks you to check the pressure in each tire, including the spare if equipped, at least monthly. See our Jeep Grand Cherokee tire pressure guide and lug nut torque guide.
From the 2026 Jeep Grand Cherokee owner's manual (Tires: Tire Loading and Tire Pressure; Replacement Tires; Life of Tire), read November 4, 2026.
