The 2023 Jeep Trucks Gladiator blends Wrangler-derived trail character with the added utility of a midsize pickup, which makes tire fitment especially dependent on the exact trim and wheel package. Across the Gladiator range, tire choices span five primary radial sizes: 245/75R17, 255/75R17, 285/70R17, 255/70R18, and 275/55R20. That means the first step is not simply picking a tread, but confirming the sub-model and wheel diameter already on the truck. Current product coverage here centers on all-terrain radial options with raised white letter styling in the supported sizes, making the decision as much about intended use and wheel match as appearance.
Which Tire Size Is Right for The 2023 Jeep Trucks Gladiator
The 2023 Jeep Trucks Gladiator uses five primary tire sizes, and they vary by sub-model and wheel diameter. Before choosing a tire, identify the exact trim and confirm whether the truck is running a 17-inch, 18-inch, or 20-inch wheel, since that determines which of the Gladiator’s radial fitments applies.
245/75R17 is a metric radial size that uses a 245-millimeter nominal section width, a 75-series profile, and a 17-inch rim. On the 2023 Jeep Trucks Gladiator, this size serves trims that use a practical 17-inch wheel and a taller sidewall than lower-profile alternatives. Available product coverage in this size includes a BFGoodrich All-Terrain T/A KO2 with raised white letter styling. This size is the right starting point when the truck is a Freedom, Sport, or Sport S and the goal is to stay with the original wheel diameter while choosing an all-terrain tire that suits real road and trail use.
275/55R20 is a metric radial size with a 275-millimeter nominal section width, a 55-series aspect ratio, and a 20-inch rim diameter. On the 2023 Jeep Trucks Gladiator, this size belongs to a trim that uses a larger wheel and a noticeably lower-profile sidewall than the 17-inch and 18-inch fitments. Its role in the Gladiator lineup is tied closely to that wheel package rather than general interchangeability across trims. This size should be evaluated only after confirming the truck’s existing 20-inch wheels, because moving between Gladiator sizes also changes sidewall profile and wheel requirements.
285/70R17 is a metric radial size with a 285-millimeter nominal section width, a 70-series profile, and a 17-inch rim. On the 2023 Jeep Trucks Gladiator, it serves the Mojave and Rubicon trims and represents one of the broader, taller factory-type fitments in the range. Available products in this size include BFGoodrich All-Terrain T/A KO2 options with raised white letter sidewalls, with choices that differ in load specification and other product details. This is the size to compare when the truck already uses the 17-inch wheel setup associated with those trims and tire selection needs to match that more substantial fitment.
255/70R18 is a metric radial size that pairs a 255-millimeter nominal section width with a 70-series profile on an 18-inch rim. On the 2023 Jeep Trucks Gladiator, this fitment is tied to a specific trim rather than shared broadly across the lineup, so it should be treated as a trim-specific wheel-and-tire combination. Its balance of width, sidewall height, and rim diameter places it between the 17-inch and 20-inch Gladiator fitments. This size makes sense only after confirming the truck is equipped with the matching 18-inch wheels and has not been changed to another Gladiator wheel package.
255/75R17 is a metric radial size with a 255-millimeter nominal section width, a 75-series profile, and a 17-inch rim diameter. On the 2023 Jeep Trucks Gladiator, this size is used on trims that combine a 17-inch wheel with a slightly taller sidewall than the 255/70R18 alternative. Its fitment role is trim-specific, so it should not be selected simply because it shares the same rim diameter as other 17-inch Gladiator tires. This size is the appropriate place to start when the truck is a Texas Trail, Willys, or Willys Sport and the goal is to match the existing wheel setup before comparing tread and use-case priorities.
Tire fitment for the 2023 Jeep Trucks Gladiator depends heavily on the exact sub-model, and several trims use different sizes even when they share the same basic vehicle platform. Checking the trim first helps avoid mixing 17-inch, 18-inch, and 20-inch wheel packages or choosing the wrong overall tire profile.

2023 Jeep Trucks Gladiator Freedom
The 2023 Jeep Trucks Gladiator Freedom uses the 245/75R17 radial size. Tire selection here is mainly about staying with the correct 17-inch wheel fitment and then comparing available all-terrain product details and sidewall presentation.
The 2023 Jeep Trucks Gladiator High Altitude uses 275/55R20 radials. That makes wheel diameter especially important, since this trim’s tire choice is tied to a 20-inch setup rather than the taller-sidewall 17-inch and 18-inch Gladiator fitments.
The 2023 Jeep Trucks Gladiator Mojave uses the 285/70R17 radial size. Selecting tires for this trim means confirming the 17-inch wheel package and then comparing the available 285/70R17 all-terrain options by load specification and related product characteristics.
The 2023 Jeep Trucks Gladiator Overland uses 255/70R18 radials. Tire choice starts with confirming the 18-inch wheel setup, since moving to another Gladiator size would also change the wheel and sidewall profile combination.
The 2023 Jeep Trucks Gladiator Rubicon also uses the 285/70R17 radial size. That gives the owner a focused decision around the correct 17-inch fitment and which available all-terrain product best matches intended road, trail, and load demands.
The 2023 Jeep Trucks Gladiator Sport uses the 245/75R17 radial size. The main consideration is keeping the tire matched to the 17-inch wheel package and selecting an appropriate all-terrain option within that size.
The 2023 Jeep Trucks Gladiator Sport S uses the same 245/75R17 radial fitment as other 17-inch trims in this group. Tire selection is straightforward once the wheel diameter is confirmed, with the real comparison centered on product specification and intended use.
The 2023 Jeep Trucks Gladiator Texas Trail uses 255/75R17 radials. Since other Gladiator trims also use 17-inch wheels but different tire sizes, the important step is confirming the exact trim and existing tire code before choosing a replacement.
The 2023 Jeep Trucks Gladiator Willys uses the 255/75R17 radial size. That keeps the decision centered on matching the correct 17-inch fitment first, then evaluating tread style and use needs within that specific size.
The 2023 Jeep Trucks Gladiator Willys Sport also uses 255/75R17 radials. Choosing tires for this trim means verifying that exact size on the truck, especially because other Gladiator 17-inch applications use different widths and profiles.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Owners usually need to sort out exact trim, wheel diameter, tire size meaning, and how the available all-terrain options compare. These answers focus on Gladiator fitment, product selection, and the checks worth making before regular road or trail use.
Tire Size & Fitment
What tire size fits a 2023 Jeep Trucks Gladiator?
The 2023 Jeep Trucks Gladiator uses several tire sizes depending on trim: 245/75R17, 255/75R17, 285/70R17, 255/70R18, and 275/55R20. All of these are radial fitments, and each one is tied to a particular wheel diameter and sub-model rather than being universal across the Gladiator lineup.
The practical next step is to confirm the exact trim and the tire code already on the truck before choosing a replacement. A 17-inch Gladiator wheel does not automatically mean any 17-inch Gladiator tire size is appropriate, because width and profile differ among Freedom, Sport, Rubicon, Mojave, Willys-family, and other trim-specific setups.
What size rim does a 2023 Jeep Trucks Gladiator use?
A 2023 Jeep Trucks Gladiator can use 17-inch, 18-inch, or 20-inch rims depending on sub-model. The tire fitments in this range are built around those wheel diameters, with 245/75R17, 255/75R17, and 285/70R17 on 17-inch rims, 255/70R18 on an 18-inch rim, and 275/55R20 on a 20-inch rim.
Wheel diameter should be confirmed before anything else, especially on a truck that may have had wheels changed after delivery. Reading the tire size on the sidewall is usually the quickest check, but measuring or verifying the wheel itself is worthwhile if the Gladiator has aftermarket wheels or the current tire markings are no longer trusted.
Which tire size should I use for my 2023 Jeep Trucks Gladiator sub-model?
Trim determines the correct primary size on the 2023 Jeep Trucks Gladiator. Freedom, Sport, and Sport S use 245/75R17; Mojave and Rubicon use 285/70R17; Overland uses 255/70R18; High Altitude uses 275/55R20; and Texas Trail, Willys, and Willys Sport use 255/75R17.
That makes sub-model identification more important than simply matching the vehicle name. It also helps to confirm the wheel package actually on the truck, because a modified Gladiator may wear a different setup than its original trim-based fitment. Matching size, wheel diameter, and intended use together gives the clearest path to a correct replacement choice.
Choosing the Right Tire
What should I consider when choosing a 2023 Jeep Trucks Gladiator tire?
Start with the correct trim-specific size and wheel diameter, since the 2023 Jeep Trucks Gladiator uses several different radial fitments. After that, compare the tire’s intended use, construction details, approved rim-width range, load specification, and whether the tread style matches how the truck is actually driven on pavement, dirt, or mixed conditions.
Product choice becomes more meaningful once fitment is settled. A Gladiator used for daily driving may need a different balance than one carrying gear or seeing frequent off-pavement use. The truck’s current wheel setup, suspension condition, and any changes from stock should all be checked before settling on a replacement in the original size.
What sidewall styles are available for 2023 Jeep Trucks Gladiator tires?
Among the supported products here, the available sidewall style for the 2023 Jeep Trucks Gladiator is RWL, or raised white letter. That appearance is offered on the BFGoodrich All-Terrain T/A KO2 products shown in the supported 17-inch Gladiator sizes and gives the tire a more traditional off-road performance look.
Sidewall style is mainly an appearance choice once the correct size is confirmed, but it can still matter to owners who want the truck to look closer to a specific trim personality or use pattern. It is worth deciding whether the white lettering suits the Gladiator’s presentation, especially if the truck is being kept cleanly street-oriented rather than trail-focused.
What tire series are available for the 2023 Jeep Trucks Gladiator?
The supported products here for the 2023 Jeep Trucks Gladiator are from the BFGoodrich All-Terrain T/A KO2 series. That series appears in the listed 245/75R17 and 285/70R17 Gladiator fitments and is paired with radial construction and raised white letter sidewalls in the available product coverage.
Series information helps separate overall tire character from simple size matching. Once the trim and wheel diameter are verified, comparing products within a known all-terrain series can help an owner focus on specification details such as load capacity, weight, and approved rim-width range instead of accidentally crossing into an incorrect Gladiator fitment.
Restoration & Appearance
Does correct tire fitment matter for a 2023 Jeep Trucks Gladiator restoration or appearance build?
Yes. Even on a modern truck like the 2023 Jeep Trucks Gladiator, correct tire fitment has a strong effect on stance, wheel-to-tire proportion, and the overall look of the finished build. The Gladiator’s trim range uses several distinct sizes, so keeping the tire matched to the proper wheel diameter is a basic part of preserving the intended visual balance.
Appearance builds often drift off course when a tire is chosen only by tread style or wheel design. Confirming whether the truck began with a 17-inch, 18-inch, or 20-inch package helps keep sidewall height and width in proportion. Owners pursuing exact visual authenticity should also compare against trim-specific reference photos or marque-specific guidance.
Which sidewall style suits a period-style or traditional-looking 2023 Jeep Trucks Gladiator?
Raised white letter sidewalls suit a traditional off-road-inspired Gladiator presentation well, and that is the sidewall style represented in the supported products here. On the 2023 Jeep Trucks Gladiator, RWL adds visual emphasis to the tire itself and works naturally with the all-terrain character of the BFGoodrich KO2 offerings.
The right appearance still depends on the trim and the look being pursued. A Willys-family or Rubicon-style build may welcome visible sidewall lettering, while a cleaner street-oriented setup may call for a more understated presentation if other tire choices are being considered elsewhere. Matching sidewall style to wheel finish and ride height usually matters as much as the tread itself.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2023 Jeep Trucks Gladiator?
Yes. Modifications can change how a 2023 Jeep Trucks Gladiator accepts its original tire size or any replacement under consideration. Aftermarket wheels, different offsets, suspension lifts, leveling kits, lowering changes, fender alterations, or steering components can all influence clearance even when the truck still appears to be running a familiar Gladiator tire size.
That matters because the Gladiator already uses several trim-specific sizes from the factory. A replacement should be checked against the actual wheel diameter and width on the truck, along with clearance at full steering lock and suspension movement. Verifying the setup on the vehicle itself is especially important before choosing among the various 17-inch Gladiator fitments.
What should I inspect before driving a 2023 Jeep Trucks Gladiator on new tires?
Before regular road use, inspect wheel condition, lug hardware, valve stems, inflation pressure, and the tire’s seating on the rim. It also helps to confirm that the installed size matches the Gladiator’s trim and wheel package, and that there is no rubbing at the suspension, inner fender, or steering components.
A short check drive should be followed by another look for air loss, unusual contact marks, or vibration. Trucks that see trail use or carry heavier loads deserve extra attention to alignment, suspension wear, and shock condition, because those factors affect how a new tire behaves even when the basic size and wheel diameter are correct.
How often should tires on a 2023 Jeep Trucks Gladiator be inspected?
Tires on a 2023 Jeep Trucks Gladiator should be inspected regularly, not just when tread appears worn. Checking pressure, tread condition, cuts, punctures, sidewall damage, and uneven wear patterns on a routine basis helps catch problems early, especially on a truck that may alternate between highway driving, hauling, and off-pavement use.
A quick visual check before longer trips is worthwhile, and a closer inspection becomes even more important after trail driving or contact with debris. Uneven wear can also signal alignment or suspension issues rather than a tire problem alone. Keeping the correct pressure for the tire in service and watching for gradual air loss will help protect both ride quality and tire life.
