The 2023 Jeep Trucks Grand Wagoneer L brings the modern Grand Wagoneer name into full-size luxury SUV territory, with the extra L wheelbase aimed at buyers who want more passenger and cargo room without giving up the model’s upscale presence. On this exact vehicle, tire selection starts with two radial fitments: 275/55R20 and 285/45R22. That makes wheel diameter and sub-model confirmation especially important before choosing a replacement. The decision then shifts to whether the vehicle is riding on the 20-inch or 22-inch setup and how that choice affects appearance, stance, and replacement planning. For everyday road use, matching the correct size to the actual wheel package matters more than simply choosing by model name alone.
Which Tire Size Is Right for The 2023 Jeep Trucks Grand Wagoneer L
The 2023 Jeep Trucks Grand Wagoneer L uses two primary tire sizes, and the right one depends on the exact sub-model and wheel package. Both fitments are radial, but they use different rim diameters, so the first step is confirming whether the vehicle has the 20-inch or 22-inch wheel setup before comparing replacement tires.
The size 275/55R20 identifies a metric radial tire with a 275-millimeter section width, a 55-series aspect ratio, and fitment for a 20-inch rim. On the 2023 Jeep Trucks Grand Wagoneer L, this is one of the primary modern radial fitments and is tied to the 20-inch wheel setup rather than the larger 22-inch package. It gives buyers a straightforward current-format size that is easy to recognize when checking existing sidewalls. This is the size to evaluate if the vehicle is equipped with 20-inch wheels and you want to stay with the original wheel diameter already on the SUV.
Fit(s): Base, Obsidian, Series II, Series III, and Series III Obsidian
Construction: Radial|Rim: 22 in
The size 285/45R22 denotes a metric radial tire with a 285-millimeter section width, a 45-series aspect ratio, and a 22-inch rim diameter. On the 2023 Jeep Trucks Grand Wagoneer L, this fitment is used across several sub-models and corresponds to the larger wheel package. Its sizing format is familiar to modern SUV owners, but the key point is that it belongs on a 22-inch wheel, not a 20-inch wheel. This is the size to confirm if the vehicle carries the larger-diameter factory-style setup and you want to match that existing wheel configuration.
Sub-model fitment matters on the 2023 Jeep Trucks Grand Wagoneer L because tire size changes with the wheel package. Some versions use only the 22-inch fitment, while the Base can appear with either of the two primary radial sizes.

2023 Jeep Trucks Grand Wagoneer L Base
The 2023 Jeep Trucks Grand Wagoneer L Base is the one covered sub-model with two possible radial tire sizes, so wheel confirmation is essential before ordering replacements. The practical decision is whether the SUV is equipped with the 20-inch or 22-inch setup, since that determines which size belongs on it.
The 2023 Jeep Trucks Grand Wagoneer L Obsidian uses the 22-inch radial fitment rather than the alternate 20-inch size. That keeps replacement selection fairly direct, with the main priority being a correct match to the existing 22-inch wheel package.
The 2023 Jeep Trucks Grand Wagoneer L Series II uses the 22-inch radial tire setup. For replacement planning, the key step is matching the vehicle’s current 22-inch wheel diameter and staying with the proper size rather than assuming every Grand Wagoneer L uses the same tire.
The 2023 Jeep Trucks Grand Wagoneer L Series III uses the 22-inch radial fitment. Tire selection is more straightforward here than on the Base, since the main task is confirming the existing 22-inch wheels and choosing a replacement that matches that configuration.
2023 Jeep Trucks Grand Wagoneer L Series III Obsidian
The 2023 Jeep Trucks Grand Wagoneer L Series III Obsidian uses the 22-inch radial setup. That means the focus stays on maintaining the correct 22-inch fitment and checking the actual wheel package on the vehicle before moving into brand or tread selection.
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.
Frequently Asked Questions
These FAQs focus on the exact tire sizes used on the 2023 Jeep Trucks Grand Wagoneer L, how fitment changes by sub-model and wheel package, and what to inspect before replacement or road use.
Tire Size & Fitment
What tire size fits a 2023 Jeep Trucks Grand Wagoneer L?
The 2023 Jeep Trucks Grand Wagoneer L uses two primary tire sizes: 275/55R20 and 285/45R22. Both are radial fitments, but they are not interchangeable because they belong to different wheel diameters. The Base can use either size, while the Obsidian, Series II, Series III, and Series III Obsidian use 285/45R22.
The practical first step is checking the actual wheel package on the vehicle rather than ordering by model name alone. A 20-inch wheel requires the 275/55R20 fitment, and a 22-inch wheel requires the 285/45R22 fitment. Looking at the current tire sidewall and confirming the wheel diameter prevents ordering a correct-looking size that does not match the wheel.
What size rim does a 2023 Jeep Trucks Grand Wagoneer L use?
The 2023 Jeep Trucks Grand Wagoneer L uses either a 20-inch or 22-inch rim, depending on the tire size and sub-model configuration. The 275/55R20 fitment uses a 20-inch rim, while the 285/45R22 fitment uses a 22-inch rim. Both are modern radial setups.
That rim difference is the most important fitment checkpoint on this vehicle because the two tire sizes are tied directly to different wheel diameters. Measuring or confirming the wheel before replacement is especially useful on a Base model, since it can appear with either setup. The tire sidewall is usually the fastest place to verify both the size and the corresponding rim diameter.
Why does the 2023 Jeep Trucks Grand Wagoneer L have more than one tire size?
The 2023 Jeep Trucks Grand Wagoneer L has more than one tire size because different sub-models and wheel packages use different wheel diameters. The Base can be equipped with either 275/55R20 or 285/45R22, while the other covered sub-models use 285/45R22. Both are primary radial fitments for this model line.
That means tire selection starts with identifying the exact sub-model and then verifying the actual wheels on the vehicle. It is possible for two Grand Wagoneer L SUVs from the same year to need different replacement tires even though they share the same model name. Using the current sidewall markings and wheel diameter keeps the decision clear and avoids mismatching tire and rim.
Choosing the Right Tire
What should I consider when choosing a 275/55R20 or 285/45R22 tire for a 2023 Jeep Trucks Grand Wagoneer L?
Start with the correct primary size for the vehicle’s actual wheel package. A 2023 Jeep Trucks Grand Wagoneer L with 20-inch wheels uses 275/55R20, while a 22-inch setup uses 285/45R22. Both fitments are radial, so the main selection issue is matching the tire to the wheel diameter already on the SUV.
After size is confirmed, compare the tire’s intended use with how the vehicle is driven. A family road-trip vehicle, a daily luxury SUV, and a lightly used spare vehicle may lead a buyer to different tread or brand preferences even within the same size. It also helps to check current wheel condition, tire wear pattern, and any prior changes that may affect replacement decisions.
How do I choose between the available tires for a 2023 Jeep Trucks Grand Wagoneer L?
The first filter is always fitment, not brand preference. On the 2023 Jeep Trucks Grand Wagoneer L, the correct tire must match either the 275/55R20 or 285/45R22 setup already on the vehicle. Once that is settled, the remaining comparison comes down to tire type, tread character, and the kind of driving the SUV actually sees.
Replacement planning is easier when the current tires are checked for wear pattern, age, and ride concerns before choosing a new set. Uneven shoulder wear, vibration, or prior suspension work can point to issues worth correcting before installation. That approach helps ensure the next tire choice supports the vehicle’s actual condition rather than simply matching the numbers on the sidewall.
Restoration & Appearance
Does correct tire fitment matter for a 2023 Jeep Trucks Grand Wagoneer L restoration?
Correct tire fitment still matters even on a late-model vehicle like the 2023 Jeep Trucks Grand Wagoneer L because the size is tied directly to the wheel package and overall presentation. The difference between 275/55R20 and 285/45R22 affects whether the SUV keeps its intended 20-inch or 22-inch stance and visual balance.
A restoration-minded or appearance-focused owner should begin by confirming how the vehicle is currently equipped and whether the goal is to preserve that setup. Matching the right tire to the right wheel diameter is more important than chasing a similar-looking alternative. If the SUV has had wheel changes, checking the full combination before replacement helps avoid an appearance mismatch.
How does tire construction affect the appearance of a restored 2023 Jeep Trucks Grand Wagoneer L?
On the 2023 Jeep Trucks Grand Wagoneer L, both primary fitments are radial, so the bigger appearance factor is size and wheel diameter rather than a bias-ply-versus-radial decision. A 20-inch 275/55R20 setup and a 22-inch 285/45R22 setup create different visual proportions even though both are modern radial configurations.
For an owner trying to preserve a particular showroom-style look, the priority is keeping the SUV on the correct wheel-and-tire combination for its exact configuration. Looking only at width or only at rim diameter can lead to an unbalanced result. Checking the current setup carefully helps maintain the intended stance, sidewall profile, and overall visual character.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2023 Jeep Trucks Grand Wagoneer L?
Yes. Modifications can affect tire fitment on a 2023 Jeep Trucks Grand Wagoneer L even when the vehicle originally used either 275/55R20 or 285/45R22. Aftermarket wheels, offset changes, suspension lowering or lifting, and body alterations can all change how much room the tire has during steering and suspension travel.
That matters because a tire that matches the original size still needs to work with the actual wheel and chassis setup now on the SUV. Checking wheel diameter, wheel width, clearance at full lock, and room around the fender and suspension helps prevent surprises. Any modified vehicle benefits from a closer inspection before new tires are selected and installed.
What should I inspect before driving a 2023 Jeep Trucks Grand Wagoneer L on new tires?
Before driving a 2023 Jeep Trucks Grand Wagoneer L on new tires, inspect the wheels for damage, verify that the new tires match the correct 20-inch or 22-inch fitment, and make sure inflation is set properly for the installed tires. It is also smart to look at the old tires for uneven wear that could point to alignment or suspension issues.
A brief post-installation check can save time later. Watch for vibration, steering pull, unusual rubbing, or changes in ride quality during the first miles. Rechecking air pressure after initial use is worthwhile, especially if the vehicle has been parked for a while or had seasonal wheel changes. Those simple steps help confirm that the replacement tires are working as intended.
How often should tires on a 2023 Jeep Trucks Grand Wagoneer L be inspected?
Tires on a 2023 Jeep Trucks Grand Wagoneer L should be inspected regularly, not just when tread looks low. A quick check for air loss, cuts, punctures, bulges, and uneven wear is worthwhile throughout the year, especially on a large luxury SUV that may carry passengers and cargo over long distances.
It also helps to inspect more carefully before road trips or after any impact with curbs or potholes. Owners should pay attention to tread wear across the full width of the tire and look for signs that alignment or suspension condition may be affecting the contact patch. Frequent visual checks and pressure checks are the simplest way to catch small issues early.
