The 2019 Jeep Trucks Wrangler sits squarely in the modern Wrangler tradition, blending removable-top utility and trail-focused capability with everyday drivability. Buyers looking at this generation are often balancing factory-style fitment, off-road intent, and the realities of street use on a vehicle that may already have seen wheel or suspension changes. Tire fitment for the 2019 Jeep Trucks Wrangler spans four primary radial sizes: 245/75R17, 255/75R17, 285/70R17, and 255/70R18. Available choices in the covered sizes lean toward BFGoodrich All-Terrain T/A KO2 products with raised white letter styling. The key is matching the correct size to the exact sub-model and wheel diameter before comparing load range, rim-width compatibility, and overall use.
Which Tire Size Is Right for The 2019 Jeep Trucks Wrangler
The 2019 Jeep Trucks Wrangler uses four primary tire sizes, and the correct one depends on the exact sub-model and wheel diameter. Three sizes fit 17-inch wheels, while 255/70R18 fits an 18-inch wheel, so confirming both the trim level and the wheels currently on the vehicle is the first step before comparing tread style, load specification, or other product details.
285/70R17 is a metric radial size in which 285 indicates nominal section width in millimeters, 70 is the aspect ratio, R designates radial construction, and 17 is the wheel diameter in inches. On the 2019 Jeep Trucks Wrangler, this size is used on Rubicon models and reflects a larger, more aggressive factory fitment approach than the narrower Wrangler sizes. Available examples include BFGoodrich All-Terrain T/A KO2 tires with raised white letter sidewalls and differing load specifications. This is the size to evaluate when the vehicle is a Rubicon and still uses the correct 17-inch wheel setup.
Fit(s): Sport, Sport S, Unlimited Sport, and Unlimited Sport S
Construction: Radial|Rim: 17 in
245/75R17 is a metric radial size with a 245-millimeter nominal section width, a 75-series aspect ratio, radial construction, and a 17-inch rim diameter. This size is used across several 2019 Jeep Trucks Wrangler Sport and Sport S configurations, making it one of the most common Wrangler fitments in this model year. The available product selection in this size includes a BFGoodrich All-Terrain T/A KO2 with raised white letters and a defined rim-width range. It is the right starting point when maintaining a stock-style 17-inch setup on the Sport-based trims.
255/75R17 is a metric radial size where 255 is the nominal section width in millimeters, 75 is the aspect ratio, R indicates radial construction, and 17 identifies the wheel diameter. On the 2019 Jeep Trucks Wrangler, this size belongs to the Unlimited Moab and sits between the narrower Sport fitment and the wider Rubicon setup. That gives it a distinct role rather than making it a catch-all Wrangler size. Use this fitment only after confirming the vehicle is an Unlimited Moab or has been intentionally kept on that specific 17-inch tire and wheel combination.
255/70R18 is a metric radial size with a 255-millimeter nominal section width, a 70-series aspect ratio, and an 18-inch wheel diameter. This size is tied to the 2019 Jeep Trucks Wrangler Unlimited Sahara, so the wheel diameter is the critical distinction before any tire comparison begins. Even though its section width is similar to 255/75R17, it is built for a different rim diameter and should be treated as a separate fitment path. Buyers with an Unlimited Sahara should confirm that the vehicle still carries the correct 18-inch wheels before selecting replacement tires.
Sub-model fitment matters on the 2019 Jeep Trucks Wrangler because tire size changes across the range rather than staying uniform. Identifying the exact trim and confirming whether the vehicle has 17-inch or 18-inch wheels will narrow the tire search quickly and avoid comparing the wrong sizes.

2019 Jeep Trucks Wrangler Rubicon
The 2019 Jeep Trucks Wrangler Rubicon uses the 285/70R17 radial size, giving it a distinct fitment from the Sport-based models and the 18-inch Sahara setup. Tire selection here centers on maintaining the correct 17-inch sizing while comparing load specification, sidewall presentation, and wheel compatibility.
The 2019 Jeep Trucks Wrangler Sport uses the 245/75R17 radial size, which is shared with several other Sport-family trims. That makes the choice less about sorting through multiple factory sizes and more about confirming the stock wheel setup before selecting among the available all-terrain options.
The 2019 Jeep Trucks Wrangler Sport S also uses 245/75R17 radial tires on a 17-inch wheel. Buyers replacing tires on this trim should stay focused on correct size, rim-width compatibility, and how the tire’s load specification suits the vehicle’s current use and any added accessories.
The 2019 Jeep Trucks Wrangler Unlimited Moab uses the 255/75R17 radial size, which gives it its own fitment position within the Wrangler lineup. That means the first step is confirming the vehicle still carries the proper 17-inch Moab wheel setup before comparing tread style or other product details.
The 2019 Jeep Trucks Wrangler Unlimited Rubicon shares the 285/70R17 radial fitment with the two-door Rubicon. Tire selection for this trim should begin with the correct 17-inch size, then move to practical details such as load capacity, intended use, and compatibility with the wheels currently on the vehicle.
The 2019 Jeep Trucks Wrangler Unlimited Sahara uses 255/70R18 radial tires, making wheel diameter the key distinction for this trim. A buyer should confirm that the Sahara still has its 18-inch wheel package before evaluating replacement tires, since similarly sized 17-inch options are not the same fitment.
The 2019 Jeep Trucks Wrangler Unlimited Sport uses the same 245/75R17 radial size found on the standard Sport models. That shared fitment keeps replacement straightforward as long as the vehicle remains on the proper 17-inch wheels and has not been altered with aftermarket tire and wheel changes.
The 2019 Jeep Trucks Wrangler Unlimited Sport S also uses 245/75R17 radial tires. For this trim, the main selection questions are less about factory size differences and more about confirming wheel compatibility, intended driving mix, and whether the current setup still matches the original fitment path.
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.

Tire Size & Fitment
What tire size fits a 2019 Jeep Trucks Wrangler?
The 2019 Jeep Trucks Wrangler uses four primary tire sizes: 245/75R17, 255/75R17, 285/70R17, and 255/70R18. The correct size depends on the sub-model, with Sport and Sport S variants using 245/75R17, Rubicon models using 285/70R17, Unlimited Moab using 255/75R17, and Unlimited Sahara using 255/70R18.
The practical issue is identifying the exact trim and checking the wheels currently on the vehicle before ordering tires. Many Wranglers are modified with different wheels, lifts, or larger tires, so the best starting point is the sub-model name plus the actual wheel diameter now on the Jeep, not the assumption that every 2019 Wrangler uses the same size.
What size rim does a 2019 Jeep Trucks Wrangler use?
A 2019 Jeep Trucks Wrangler uses either a 17-inch or 18-inch rim, depending on the sub-model and tire size. The 245/75R17, 255/75R17, and 285/70R17 fitments use 17-inch wheels, while 255/70R18 uses an 18-inch wheel on the Unlimited Sahara.
Wheel diameter should be confirmed before comparing tires, because two sizes with similar width and profile numbers are not interchangeable if the rim diameter is different. It also helps to verify wheel width, since supported products carry their own approved rim-width ranges and those can matter on a Wrangler that has already been fitted with aftermarket wheels.
Do all 2019 Jeep Trucks Wrangler sub-models use the same tire size?
No, 2019 Jeep Trucks Wrangler sub-models do not all use the same tire size. Sport, Sport S, Unlimited Sport, and Unlimited Sport S use 245/75R17, Rubicon and Unlimited Rubicon use 285/70R17, Unlimited Moab uses 255/75R17, and Unlimited Sahara uses 255/70R18.
That variation means trim level matters before any product comparison begins. A buyer looking at tread pattern, load specification, or sidewall style should first confirm whether the Jeep is a Sport-based model, a Rubicon, a Moab, or a Sahara, then verify that the wheels on the vehicle still match that original size family.
Choosing the Right Tire
What should I consider when choosing a tire for a 2019 Jeep Trucks Wrangler?
Start with the correct tire size for the exact 2019 Jeep Trucks Wrangler sub-model and wheel diameter. From there, compare whether the available tire matches the Jeep’s intended use, the product’s rim-width range, and any load specification that may matter for added gear, trail use, or a heavier build.
Wrangler buyers also tend to care about tread character and sidewall presentation, especially on vehicles used both on-road and off-road. A Jeep that remains close to stock may be straightforward, while one with aftermarket wheels, suspension changes, or armor deserves a closer look at wheel width, clearance, and the actual tire size already mounted.
What sidewall styles are available for 2019 Jeep Trucks Wrangler tires?
The available products for the covered 2019 Jeep Trucks Wrangler sizes use RWL sidewalls, which means raised white letters. That gives these tires a more traditional off-road performance appearance than a plain black sidewall and can play a noticeable role in the Jeep’s overall presentation.
Sidewall style does not change the basic fitment, but it does change how the vehicle looks once mounted. Some owners prefer the classic all-terrain look of raised white letters, while others may be trying to match an existing set or maintain a more understated finish, so appearance should be weighed alongside the correct size and wheel compatibility.
What brands offer tires for the 2019 Jeep Trucks Wrangler?
The available products for the covered 2019 Jeep Trucks Wrangler sizes are from BFGoodrich. The supported examples center on the All-Terrain T/A KO2 line, which appears in the listed Wrangler fitments with radial construction and raised white letter sidewalls.
That makes the selection process more about choosing the correct size and specification within the available BFGoodrich offering rather than sorting through several brands. Buyers should still compare the product’s rim-width range, load capacity at its stated pressure, and whether the tire matches the Jeep’s current wheel setup and intended driving mix.
Restoration & Appearance
How does tire construction affect the appearance of a 2019 Jeep Trucks Wrangler?
The 2019 Jeep Trucks Wrangler uses radial tires, so the appearance question is less about bias-ply versus radial and more about tread and sidewall presentation within modern radial fitment. In the covered products, raised white letter styling gives the Jeep a stronger all-terrain visual character than a plain black sidewall would.
Appearance still needs to stay grounded in the correct size for the trim level. A Rubicon on 285/70R17 projects a different stance than a Sport on 245/75R17, and a Sahara’s 255/70R18 adds another visual distinction, so keeping the proper fitment is part of maintaining the Jeep’s intended look.
Does correct tire fitment matter for a 2019 Jeep Trucks Wrangler restoration or stock-style build?
Yes, correct tire fitment matters on a 2019 Jeep Trucks Wrangler if the goal is a stock-style or carefully presented build. The right size helps preserve the intended relationship between wheel diameter, sidewall height, and overall stance, whether the Jeep is a Sport, Rubicon, Moab, or Sahara.
A visually tidy result starts with the proper sub-model size before moving on to details like sidewall style and tread character. Many later Wranglers have already been changed from stock, so checking the current wheel package and comparing it to the intended trim-specific fitment is an important step before replacing tires for appearance reasons.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 Jeep Trucks Wrangler?
Yes, modifications can affect tire fitment on a 2019 Jeep Trucks Wrangler even when the original sub-model size is known. Aftermarket wheels, changes in wheel width or offset, suspension lifts, leveling kits, and body or fender alterations can all change how a tire sits and whether it clears at full steering lock or suspension movement.
That is especially important on Wranglers because many no longer remain in stock configuration. A replacement tire should be checked against the actual wheel diameter and width on the Jeep now, then reviewed for clearance around suspension parts, fenders, and steering components before assuming the factory size still tells the whole story.
What should I inspect before driving a 2019 Jeep Trucks Wrangler on new tires?
Before driving a 2019 Jeep Trucks Wrangler on new tires, inspect tire pressure, wheel-lug torque, valve stems, and visible clearance around the fenders and suspension. It is also wise to look for uneven mounting position, any contact at full steering lock, and any mismatch between the installed tire size and the wheel diameter on the Jeep.
A short, careful test drive helps confirm that the Jeep tracks normally and that no rubbing appears during turns or over suspension movement. On a vehicle used off-road or carrying extra accessories, continued checks for air loss, irregular wear, and sidewall damage are just as important as the initial installation inspection.
How often should tires on a 2019 Jeep Trucks Wrangler be inspected?
Tires on a 2019 Jeep Trucks Wrangler should be inspected regularly, especially if the Jeep sees trail use, sits for long periods, or carries added equipment. Routine checks should include tread wear, cuts, punctures, sidewall cracking, bulges, and pressure loss, since all of those can affect how the tire performs on both pavement and rougher surfaces.
Wranglers benefit from more frequent visual checks than many ordinary passenger vehicles because their use often includes uneven terrain and low-speed impacts. It also helps to inspect after off-road trips and before longer highway drives, with extra attention paid to any tire that has been run at different pressures or mounted on aftermarket wheels.
