How to read the tire size
Using LT285/70R17C from the table above as an example, here is what each part means according to the owner's manual tire sizing chart:
| Part | Example | What it means |
|---|---|---|
| Prefix | LT | P is a passenger tire to US standards, LT is a light truck tire to US standards, and no letter means a passenger tire to European standards |
| Section width | 285 | Width of the tire in millimeters |
| Aspect ratio | 70 | Section height as a percent of section width |
| Construction | R | Radial construction (D means diagonal or bias) |
| Rim diameter | 17 | Wheel diameter in inches |
From the 2026 Jeep Gladiator 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.
What LT and C mean on Gladiator tires
The Willys, Mojave and Rubicon tires start with LT, which the owner's manual defines as a light truck tire sized to US design standards. The C at the end of LT285/70R17C is a load range letter; the manual says C, D, E, F and G are load ranges associated with the maximum load a tire can carry at a specified pressure. If you replace these tires, match the size and load range shown on your tire's sidewall and the tire placard.

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 Gladiator fuel tank size guide and our Gladiator dimensions page.
