The 2020 Jeep Trucks Wrangler carries modern Wrangler capability into a format that still invites owners to think carefully about stance, wheel setup, and real-world use. Whether the goal is trail work, daily driving, or preserving the look of a specific trim, tire choice remains tied closely to how the vehicle was configured. This Wrangler uses four primary radial tire sizes: 245/75R17, 255/75R17, 285/70R17, and 255/70R18. Available products in these sizes lean toward an all-terrain presentation, including raised white letter styling in BFGoodrich All-Terrain T/A KO2 fitments. The key decision is confirming the exact sub-model and wheel diameter before comparing load, rim-width compatibility, and overall tire character.
Which Tire Size Is Right for The 2020 Jeep Trucks Wrangler
The 2020 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 the first step is confirming the Wrangler's trim and actual wheel setup before comparing tire choices.
Fit(s): Rubicon, Rubicon Recon, Unlimited Rubicon, and Unlimited Rubicon Recon
Construction: Radial|Rim: 17 in
In 285/70R17, the 285 identifies nominal section width in millimeters, 70 is the aspect ratio, R means radial construction, and 17 is the wheel diameter in inches. On the 2020 Jeep Trucks Wrangler, this size is used on Rubicon and Rubicon Recon configurations and supports the larger, more aggressive end of the Wrangler fitment range. Available choices include BFGoodrich All-Terrain T/A KO2 products with raised white letter sidewalls and differing load specifications. This size is the one to evaluate when the Wrangler already carries the 17-inch Rubicon-style wheel setup and the buyer wants to stay within that original fitment path.
Fit(s): Sport, Sport S, Unlimited Sport, and Unlimited Sport S
Construction: Radial|Rim: 17 in
The 245/75R17 size uses a 245-millimeter nominal section width, a 75-series profile, radial construction, and a 17-inch rim diameter. It is the primary fitment for Sport and Sport S versions of the 2020 Jeep Trucks Wrangler, including Unlimited Sport and Unlimited Sport S models. BFGoodrich offers this size in the All-Terrain T/A KO2 series with raised white letter styling, along with a distinct rim-width range and load specification. This is the size to focus on when maintaining a stock-type Sport or Sport S wheel and tire configuration rather than moving into a wider Wrangler fitment.
A 255/75R17 tire has a 255-millimeter nominal section width, a 75-series profile, radial construction, and a 17-inch wheel diameter. On the 2020 Jeep Trucks Wrangler, this size is tied to the Sport Willys and Unlimited Sport Willys sub-models, placing it between the narrower Sport fitment and the wider Rubicon fitment. Its sizing gives the buyer an important clue that not every 17-inch Wrangler wheel setup uses the same tire, even when the rim diameter matches. This size should be chosen only after confirming a Willys-specific configuration or verifying that the vehicle still retains that same wheel and trim-based fitment.
The 255/70R18 format indicates a 255-millimeter nominal section width, a 70-series aspect ratio, radial construction, and an 18-inch rim diameter. This size belongs to the 2020 Jeep Trucks Wrangler Unlimited Sahara, making it the only primary Wrangler fitment here that uses an 18-inch wheel. Its role in the fitment lineup is less about width alone and more about matching the correct rim diameter and trim-specific wheel package. Buyers considering this size should confirm that the Wrangler still has its 18-inch wheel setup, since a 17-inch tire choice is not interchangeable simply because the overall proportions may appear close.
Tire fitment on the 2020 Jeep Trucks Wrangler varies by sub-model, so identifying the exact trim is essential before selecting a tire. The main dividing points are the specific model designation and whether the Wrangler uses a 17-inch or 18-inch wheel.

2020 Jeep Trucks Wrangler Rubicon
The 2020 Jeep Trucks Wrangler Rubicon uses the 285/70R17 radial size. That makes tire selection less about choosing among multiple primary sizes and more about comparing the available 17-inch products, load ratings, and all-terrain presentation within that fitment.
The 2020 Jeep Trucks Wrangler Rubicon Recon also uses 285/70R17 radial tires. Buyers with this sub-model should stay focused on that wider 17-inch fitment and confirm that the vehicle still retains its original wheel diameter before comparing product details.
The 2020 Jeep Trucks Wrangler Sport uses the narrower 245/75R17 radial fitment. Tire choice here centers on keeping the correct 17-inch size and reviewing the available all-terrain option with the proper rim-width range for this setup.
The 2020 Jeep Trucks Wrangler Sport S shares the 245/75R17 radial size. That shared fitment simplifies replacement, but it is still worth confirming the actual wheel on the vehicle if aftermarket changes have been made since new.
The 2020 Jeep Trucks Wrangler Sport Willys uses 255/75R17 radial tires rather than the Sport's 245/75R17 size. That distinction matters because matching the Willys fitment keeps the tire size aligned with the sub-model's intended wheel and tire configuration.
The 2020 Jeep Trucks Wrangler Unlimited Rubicon uses the same 285/70R17 radial size as the two-door Rubicon. Selection therefore comes down to choosing the right product within that size and verifying wheel condition, width, and intended use.
The 2020 Jeep Trucks Wrangler Unlimited Rubicon Recon also uses 285/70R17 radial tires. Staying with that size preserves the core fitment, while product comparison should focus on load specification and wheel-width compatibility.
The 2020 Jeep Trucks Wrangler Unlimited Sahara stands apart with a 255/70R18 radial tire on an 18-inch wheel. Buyers should confirm rim diameter first, since this sub-model does not share the 17-inch tire sizes used elsewhere in the Wrangler range.
The 2020 Jeep Trucks Wrangler Unlimited Sport uses 245/75R17 radial tires. That makes it part of the Sport-family fitment group, where the practical goal is maintaining the correct 17-inch size and checking the wheel setup before replacement.
The 2020 Jeep Trucks Wrangler Unlimited Sport S also uses the 245/75R17 radial size. Tire selection is straightforward once the sub-model is confirmed, with the remaining comparison centered on product specifications rather than alternate primary sizes.
The 2020 Jeep Trucks Wrangler Unlimited Sport Willys uses 255/75R17 radial tires. That places it in the Willys-specific fitment path, so buyers should avoid assuming that any other 17-inch Wrangler tire size is automatically the right choice.
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.

Wrangler owners usually need to sort out the exact tire size by trim level, then compare wheel diameter, all-terrain tire options, sidewall presentation, and real-world fitment checks. These FAQs focus on those decisions for the 2020 Jeep Trucks Wrangler.
Tire Size & Fitment
What tire size fits a 2020 Jeep Trucks Wrangler?
The 2020 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 models using 245/75R17, Sport Willys models using 255/75R17, Rubicon and Rubicon Recon models using 285/70R17, and Unlimited Sahara using 255/70R18.
That means the first step is not picking a tire brand or tread style but confirming the exact Wrangler trim and wheel diameter already on the vehicle. A 17-inch Wrangler setup can still use three different primary sizes, so checking the current sidewall marking and the sub-model helps prevent choosing the wrong fitment path.
What size rim does a 2020 Jeep Trucks Wrangler use?
The 2020 Jeep Trucks Wrangler uses either a 17-inch or 18-inch rim, depending on sub-model. The 245/75R17, 255/75R17, and 285/70R17 sizes all mount on 17-inch wheels, while the 255/70R18 size uses an 18-inch wheel and is associated with the Unlimited Sahara.
Wheel diameter should be confirmed before anything else, especially on a Wrangler that may have been modified or had wheels changed over time. Even when two tire sizes look close in overall proportions, the rim diameter itself is not negotiable, so a 17-inch tire cannot be used on an 18-inch wheel or the reverse.
Do all 2020 Jeep Trucks Wrangler sub-models use the same tire size?
No, the 2020 Jeep Trucks Wrangler does not use one tire size across every sub-model. Sport and Sport S models use 245/75R17, Sport Willys models use 255/75R17, Rubicon and Rubicon Recon models use 285/70R17, and Unlimited Sahara uses 255/70R18.
That variation is why trim identification matters before comparing products. A buyer looking at a 17-inch Wrangler still has to confirm whether the vehicle is a Sport-family, Willys, or Rubicon setup, and an Unlimited Sahara requires special attention because it moves to an 18-inch rim rather than sharing the same wheel diameter as the others.
Choosing the Right Tire
What should I consider when choosing a tire for a 2020 Jeep Trucks Wrangler?
Start with the exact primary size for the Wrangler's sub-model, then confirm wheel diameter and construction. All listed 2020 Jeep Trucks Wrangler fitments are radial, but the vehicle still spans four different sizes, so proper selection begins with matching the tire to the trim-specific fitment rather than choosing by appearance alone.
After the size is settled, compare details that affect how the tire suits the vehicle, including rim-width range, load specification, and the kind of driving the Wrangler actually sees. That approach is especially helpful on vehicles used for mixed street and trail duty, where an all-terrain tire may be desirable but still has to suit the wheel already in place.
What sidewall styles are available for 2020 Jeep Trucks Wrangler tires?
The available products for the 2020 Jeep Trucks Wrangler shown here use RWL sidewalls, meaning raised white letter styling. That sidewall treatment appears on the BFGoodrich All-Terrain T/A KO2 options offered in the listed Wrangler fitments and gives the tire a more traditional off-road and truck-oriented presentation.
Sidewall style is mainly an appearance decision once the correct size and wheel diameter are confirmed. On a Wrangler, raised white letters can reinforce the all-terrain look, but the smarter comparison is still between tires that match the sub-model's proper size, rim-width requirements, and intended use rather than selecting on lettering style by itself.
What brands offer tires for the 2020 Jeep Trucks Wrangler?
The available products shown for the 2020 Jeep Trucks Wrangler are from BFGoodrich. The listed Wrangler fitments use the All-Terrain T/A KO2 line, including multiple 285/70R17 options and a 245/75R17 option, all built as radial tires with raised white letter sidewalls.
That makes the buying decision less about comparing a long list of brands and more about matching the correct Wrangler size to the right version within that series. Checking load specification and compatible rim-width range is worthwhile, particularly on a vehicle that may carry gear, see off-pavement use, or wear wheels that differ from its original setup.
Restoration & Appearance
Which tire should I choose for a period-style 2020 Jeep Trucks Wrangler?
A period-style approach for a 2020 Jeep Trucks Wrangler still begins with the correct trim-based size, since the vehicle uses modern radial fitments rather than vintage bias-ply sizing. Choosing 245/75R17, 255/75R17, 285/70R17, or 255/70R18 according to the sub-model preserves the basic stance and wheel relationship intended for that Wrangler configuration.
Appearance then comes down to the product's visual character, especially whether an all-terrain pattern and raised white letter sidewall suit the look you want. Buyers concerned with keeping the vehicle visually close to its original-era presentation should confirm current wheels and compare the tire's profile and sidewall treatment before making a final choice.
Which sidewall style suits a period-style 2020 Jeep Trucks Wrangler?
Raised white letter sidewalls are the sidewall style represented in the available 2020 Jeep Trucks Wrangler products here. On a Wrangler, that treatment pairs naturally with the BFGoodrich All-Terrain T/A KO2's truck and off-road character, making it a strong visual fit for owners who want a more traditional utility-oriented look.
The best appearance choice still depends on the specific sub-model and how the vehicle is being presented. A Rubicon, Willys, or Sport can all wear different wheel and tire combinations, so the sidewall should be viewed as part of the overall package rather than as a stand-alone styling decision separate from size and wheel diameter.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Jeep Trucks Wrangler?
Yes, modifications can affect tire fitment on a 2020 Jeep Trucks Wrangler even when the tire size matches a known factory-style sub-model size. Wheel changes, suspension lifts, leveling kits, offset differences, or body modifications can all alter clearance at the fender, suspension, or steering components.
That is why the actual setup on the vehicle matters as much as the original trim designation. A Wrangler with aftermarket wheels may need a closer look at rim width and clearance before using the same size found on a stock model, especially when moving between the narrower Sport sizes and the wider 285/70R17 Rubicon fitment.
What should I inspect before driving a 2020 Jeep Trucks Wrangler on new tires?
Before road use, inspect wheel condition, confirm lug hardware is correct, and make sure the new tires match the Wrangler's actual wheel diameter and sub-model fitment. It is also worth checking for adequate clearance at full steering lock and during suspension movement, particularly on a vehicle used off-road or altered from stock.
Basic tire-condition checks still matter even when the tires are new. Verify inflation pressure, look for shipping damage or mounting damage, and make sure there are no rubbing points once the vehicle is on the ground. A short, careful test drive can reveal interference, vibration, or handling issues before longer use.
How often should tires on a 2020 Jeep Trucks Wrangler be inspected?
Tires on a 2020 Jeep Trucks Wrangler should be inspected regularly, not only at service intervals. A quick visual check for cuts, punctures, sidewall damage, uneven wear, and pressure loss is smart before routine driving, and a more careful inspection becomes even more important if the vehicle sees trail use or long highway runs.
Wrangler owners should also pay attention to anything that suggests alignment or clearance trouble, including edge wear, rubbing marks, or changes in steering feel. On a vehicle with all-terrain tires, those checks help catch problems early and confirm that the tire is still working properly with the wheel, suspension, and intended use.
