Jeep Gladiator Tires — Fitment by Year

The Jeep Gladiator occupies a unique position in the market as a midsize pickup truck built on a Wrangler-derived platform, purpose-built for off-road capability. That heritage shapes almost every tire decision you'll make. Unlike a typical truck or crossover, the Gladiator is frequently lifted, fitted with aftermarket bumpers, and driven on terrain that demands serious tread and sidewall durability. Tire selection here is rarely just about commuting — it's about matching rubber to the conditions you actually drive.

Factory tire sizes on the 2020–2027 Gladiator vary by trim. Sport and Sport S trims have historically shipped on smaller-diameter tires, while Rubicon trims have come with larger all-terrain tires from the factory. Across the lineup, common OEM sizes fall in the 31- to 33-inch range, though you should always confirm the exact size printed on your door jamb sticker before ordering replacement tires. Rim diameter, section width, and aspect ratio all need to match or be carefully adjusted when sizing up.

All-terrain (A/T) tires are the most popular fitment for Gladiator owners because they balance on-road manners with genuine off-road traction. If you plan to spend significant time on rock, mud, or loose dirt, a mud-terrain (M/T) tire offers more aggressive siping and larger void ratios — but expect more road noise and slightly reduced wet-pavement grip. For owners who use the Gladiator primarily as a daily driver and only occasionally venture off-road, an all-season highway tire will reduce noise and extend tread life, though it sacrifices the sidewall protection that off-road driving demands.

Sidewall strength deserves attention on any body-on-frame, off-road-capable truck. When airing down on trails — a common practice to increase the tire's footprint and improve traction — a tire with a higher ply rating or reinforced sidewall construction resists punctures and pinch flats against rocks more reliably than a standard passenger-car sidewall. Look for load range C, D, or E ratings depending on how aggressively you wheel and how much weight you carry in the bed. Load range also affects ride quality on pavement, so factor that tradeoff into your choice. If you're running a lifted Gladiator, confirm that your chosen tire diameter clears the fenders, control arms, and front sway bar under full articulation before finalizing a size.

Sizing up is one of the most common modifications Gladiator owners pursue. Many stock Rubicon owners move to 35-inch tires with a mild lift (typically 2–3.5 inches), while more committed builds run 37-inch tires with a more substantial suspension lift. Larger tires affect speedometer calibration, fuel economy, braking distances, and differential gearing — a regear is often recommended when stepping up to 37s or larger to restore acceleration and towing capacity. TPMS sensors from the factory will carry over to new wheels and tires of the same rim diameter, but a sensor relearn procedure is typically required after any tire change.

Because the Gladiator spans several model years and multiple trim levels — Sport, Sport S, Overland, Rubicon, Mojave, and Sport Altitude among them — exact OEM specs differ. Always verify your year, trim, and current rim size before ordering. If you've purchased the vehicle used or it already has a lift installed, measure the existing tire rather than relying on assumed factory specs. Getting the fitment right the first time saves time and return shipping.
