More Details on Our Top Picks
Gladiator X COMP A/T LT295/70R18
A large all-terrain on an 18-inch rim, about 2 inches taller than the 255/70R18 Overland size. It can suit a Gladiator with 18-inch wheels, usually with a lift or trimming, so confirm clearance. The listing says it blends X-COMP M/T and A/T traits with a reinforced shoulder.- Tire Size:LT295/70R18
- Load Index:129/126 (per listing)
- Speed Rating:S
- Type:All-terrain
- Rim Size:18 inches
Pros
- Fits 18-inch Gladiator wheels
- Heavy-duty light-truck construction
- All-terrain tread for mixed use
Limitations
- Much taller than the stock Overland tire
- May need a lift and re-gearing
- Brand details are limited
Gladiator X COMP A/T P275/55R20 117T XL
275/55R20 is the factory size on the High Altitude, so this is the one listing in the 20-inch range that fits a stock Gladiator. It is a passenger-metric tire, so check the load rating against your needs. Other trims use 17- or 18-inch wheels and cannot use it.- Tire Size:P275/55R20
- Load Index:117 (2,756 lb)
- Speed Rating:T
- Type:All-terrain
- Rim Size:20 inches
Pros
- Factory High Altitude size
- Non-directional tread per listing
- XL load range
Limitations
- Only fits 20-inch wheels
- Passenger-metric rather than light truck
- Limited off-road capability
Gladiator X-COMP A/T LT33/12.50R20 (Also Consider)
A 33-inch tire on a 20-inch rim. It is about 3 percent taller than the High Altitude 275/55R20 and is much wider, so it is not a bolt-on for a stock Gladiator. Treat it as an option for owners who already run suitable 20-inch wheels. Listed as 10-ply with a 114Q rating.- Tire Size:LT33/12.50R20
- Load Index:114 (2,601 lb)
- Speed Rating:Q
- Type:All-terrain
- Rim Size:20 inches
Pros
- Heavy-duty 10-ply construction per listing
- Tall tire for 20-inch wheels
Limitations
- Not a stock fit on any trim
- Wide, so wheel width and clearance matter
- Few 20-inch off-road wheels
Gladiator X-COMP M/T LT35/12.50R18
A 35-inch mud-terrain on an 18-inch rim. That is far taller than any factory Gladiator tire, so expect to need a lift, and often re-gearing. The listing’s load figure looks wrong for a tire this size, so check the sidewall load index before buying.- Tire Size:LT35/12.50R18
- Type:Mud-terrain
- Rim Size:18 inches
- Casing:Three-ply per listing
- Load Index:Verify on the listing
Pros
- Aggressive mud-terrain tread
- Fits 18-inch wheels
- Large footprint for soft ground
Limitations
- Needs a lift
- Loud and slower to stop on pavement
- Load figure in the listing is unclear
Gladiator X COMP M/T LT33/12.50R24 (Not a Gladiator Fit)
This is a 24-inch size. No factory Gladiator wheel is that large, so it fits only a build with custom 24-inch wheels. The link is kept for reference; it is not a pick for a stock or lightly modified Gladiator.- Tire Size:LT33/12.50R24
- Type:Mud-terrain
- Load Range:F (per listing)
- Speed Rating:Q
- Rim Size:24 inches
Pros
- Mud-terrain tread
- Load Range F per listing
Limitations
- Needs 24-inch wheels
- Not a bolt-on Gladiator size
- Few wheel options
GladiatorTires X-COMP M/T LT265/75R16 (Not a Gladiator Fit)
A 16-inch tire. Gladiator wheels start at 17 inches, so this does not fit a stock Gladiator. It suits older 16-inch Jeeps and trucks instead. Listed as 12-ply with a 123 load index (3,415 lb).- Tire Size:LT265/75R16
- Load Index:123 (3,415 lb)
- Speed Rating:Q
- Type:Mud-terrain
- Rim Size:16 inches
Pros
- Heavy-duty Load Range E
- Mud-terrain tread
Limitations
- Wrong rim size for a Gladiator
- Not a pick for this vehicle
- Mud-terrain road manners
GladiatorTires X-COMP M/T (Listing Conflict, Not a Fit)
The listing details conflict. The page text mentions LT265/75R16 while the product data points to LT33/12.50R22 114Q. Neither size is a Gladiator factory size, so we do not recommend it. If you are interested, read the size on the listing before buying.- Tire Size:LT33/12.50R22 or LT265/75R16
- Type:Mud-terrain
- Rim Size:Verify (22 or 16 inches)
- Load Index:114 (2,601 lb) if 33/12.50R22
- Speed Rating:Q
Pros
- Mud-terrain tread
- Heavy-duty construction
Limitations
- Size unclear
- Wrong rim for a stock Gladiator
- Not recommended
GladiatorTires X-COMP M/T 285/75R16 (Not a Gladiator Fit)
A 16-inch mud-terrain, even though the table link text said LT35/12.50R18. The product data points to 285/75R16 126Q (3,750 lb), which a stock Gladiator cannot use because its wheels start at 17 inches. It is not a Gladiator pick.- Tire Size:285/75R16
- Load Index:126 (3,748 lb)
- Speed Rating:Q
- Type:Mud-terrain
- Rim Size:16 inches
Pros
- High load index
- Mud-terrain tread
Limitations
- Wrong rim size for a Gladiator
- Listing and link text disagree
- Not a pick for this vehicle
Prinx HiCountry A/T2 245/75R17 112T
245/75R17 is the factory size on Gladiator Sport, Sport S and Freedom trims, so this is a direct replacement for them. The listing mentions three-peak mountain snowflake and M+S markings, a reinforced sidewall and a 50,000-mile tread warranty. Verify the markings on the tire you receive.- Tire Size:245/75R17
- Load Index:112 (2,469 lb)
- Speed Rating:T
- Type:All-terrain
- Winter marking:3PMSF per listing
Pros
- Factory Gladiator Sport size
- Winter marking per the listing
- Listed mileage warranty
Limitations

- Lesser-known brand
- Warranty conditions apply
Falken Wildpeak M/T01 LT285/70R17 116/113Q
285/70R17 is the factory size on the Rubicon and Mojave. This is a mud-terrain with Falken’s DURASPEC sidewall, per the listing. It is about 32.8 inches tall. A mud-terrain gives up quiet and efficiency on pavement.- Tire Size:LT285/70R17
- Load Index:116/113 (2,756/2,535 lb)
- Speed Rating:Q
- Type:Mud-terrain
- Sidewall:DURASPEC per listing
Pros
- Factory Rubicon and Mojave size
- Established brand
- Sidewall protection per listing
Limitations
- Louder than all-terrains on pavement

- Mud-terrain wear and mileage
Jeep Gladiator tires: factory sizes and fit rules
Factory sizes by trim (2020-2023, per tiresizescalculator.com; confirm on your placard):
- Sport, Sport S, Freedom: 245/75R17
- Willys: 255/75R17
- Rubicon, Mojave: 285/70R17
- Overland: 255/70R18
- High Altitude: 275/55R20
Fit checklist
- The rim diameter must match exactly. A 285/70R17 needs a 17-inch wheel.
- Staying within about 3 percent of stock diameter keeps the speedometer close. Bigger tires change it.
- Tires around 35 inches tall generally need a lift, and many owners also re-gear. Talk to a shop before buying.
- Check load index and Load Range if you tow or carry weight. See tires for towing.
- Compare Wrangler all-terrain tires and mud-terrain light-truck tires if you want more options in your size.
FAQ
What size tires does a Jeep Gladiator take?
Factory sizes are 245/75R17 (Sport), 255/75R17 (Willys), 285/70R17 (Rubicon, Mojave), 255/70R18 (Overland) and 275/55R20 (High Altitude). Check your placard to be sure.
Can I put 35-inch tires on a Gladiator?
Usually only with a lift, and many owners also re-gear. Ask a shop about clearance, speedometer calibration and load rating first.
Do 16-inch tires fit a Gladiator?
No. Factory wheels are 17-, 18- or 20-inch. Tires for 16-, 22- or 24-inch rims need different wheels.
Do bigger tires change the speedometer?
Yes. A taller tire makes the speedometer read lower than your true speed, and recalibration may be needed.
Which tire type suits daily driving?
All-terrain tires such as the Prinx HiCountry A/T2 balance road manners and trail traction. Mud-terrains are louder and wear faster on pavement.
What tire pressure should a Gladiator use?
Use the pressure on the door-jamb placard as a starting point, and see off-road tire pressure guidance for trail adjustments.
Which one to choose
For a Sport, Sport S or Freedom, the Prinx HiCountry A/T2 is the stock-size match. For a Rubicon or Mojave, the Falken Wildpeak M/T01 is the factory size. Overland owners can look at the LT295/70R18 with clearance in mind, and High Altitude owners at the P275/55R20. Skip the 16-, 22- and 24-inch listings unless you are changing wheels.
