The 2024 Jeep Trucks Grand Wagoneer blends full-size luxury SUV presence with serious road-going capability, carrying the Wagoneer name into a modern flagship format. Buyers usually approach this vehicle with a close eye on ride quality, wheel appearance, and the exact trim they own, because wheel and tire combinations are part of the package. For this model, the key fitment question centers on two radial sizes: 275/55R20 and 285/45R22. That means the real choice is not vintage construction versus modern construction, but confirming the correct wheel diameter and sub-model before selecting a replacement tire. A careful match preserves stance, clearance, and the character of a premium full-size Jeep.
Which Tire Size Is Right for The 2024 Jeep Trucks Grand Wagoneer
Two tire sizes apply to the 2024 Jeep Trucks Grand Wagoneer, and the first step is confirming which wheel diameter is on the vehicle. Fitment varies by sub-model and wheel package, with 20-inch and 22-inch radial setups both in use. Before choosing a replacement tire, identify the exact sub-model and verify whether the vehicle is riding on 20-inch or 22-inch wheels.
The 275/55R20 size is a modern metric radial format in which 275 identifies nominal section width in millimeters, 55 is the aspect ratio, R indicates radial construction, and 20 is the wheel diameter in inches. On the 2024 Jeep Trucks Grand Wagoneer, this size belongs to a 20-inch wheel setup rather than the larger 22-inch package. Its overall proportions support the Grand Wagoneer’s full-size luxury SUV role while keeping the sizing language familiar to current replacement-tire buyers. This is the size to evaluate when the vehicle has 20-inch wheels and you want to stay with the intended fitment format.
Fit(s): Base, Obsidian, Series III, and Series III Obsidian
Construction: Radial|Rim: 22 in
The 285/45R22 size is also a modern metric radial, with 285 giving the nominal width in millimeters, 45 identifying the aspect ratio, and 22 marking the wheel diameter in inches. For the 2024 Jeep Trucks Grand Wagoneer, this size corresponds to the larger 22-inch wheel fitment used across several sub-models. Compared with the 20-inch setup, the key practical distinction is wheel diameter confirmation before any replacement decision is made. This is the size to focus on when the vehicle is equipped with factory-style 22-inch wheels or an equivalent 22-inch fitment already in place.
Sub-model fitment matters on the 2024 Jeep Trucks Grand Wagoneer because tire size is not the same across the full lineup. Some versions use only the 22-inch radial setup, while the Base model can appear with either 20-inch or 22-inch wheels, so the exact trim and wheel diameter should be checked together.

2024 Jeep Trucks Grand Wagoneer Base
The 2024 Jeep Trucks Grand Wagoneer Base can use either the 275/55R20 radial size or the 285/45R22 radial size. That makes wheel confirmation especially important before choosing a replacement, since the tire decision depends on whether the vehicle has the 20-inch or 22-inch setup.
The 2024 Jeep Trucks Grand Wagoneer Obsidian uses the 285/45R22 radial size. Tire selection is therefore more straightforward here, with the main task being to stay with the correct 22-inch fitment and confirm that the wheels on the vehicle have not been changed from the expected setup.
The 2024 Jeep Trucks Grand Wagoneer Series III uses the 285/45R22 radial fitment. That keeps the replacement process centered on choosing the right tire within the 22-inch size rather than sorting through multiple primary size options for this sub-model.
2024 Jeep Trucks Grand Wagoneer Series III Obsidian
The 2024 Jeep Trucks Grand Wagoneer Series III Obsidian also uses the 285/45R22 radial size. For this sub-model, the practical focus is selecting a tire that matches the existing 22-inch wheel setup and checking current wheel condition, wear pattern, and clearance before road use.
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
Owners of a 2024 Jeep Trucks Grand Wagoneer usually need clarity on the correct tire size, the difference between the 20-inch and 22-inch setups, and what to inspect before replacing tires or putting the vehicle back on the road.
Tire Size & Fitment
What tire size fits a 2024 Jeep Trucks Grand Wagoneer?
The 2024 Jeep Trucks Grand Wagoneer uses two tire sizes: 275/55R20 and 285/45R22. Both are radial sizes, but they do not apply equally across every version of the vehicle. The Base model can use either size, while Obsidian, Series III, and Series III Obsidian use 285/45R22.
The practical step is to confirm the exact sub-model and wheel diameter before choosing a replacement tire. A Grand Wagoneer with 20-inch wheels needs the 275/55R20 fitment, while a 22-inch wheel setup takes 285/45R22. Checking the sidewall on the current tires and verifying the actual wheels on the vehicle helps avoid ordering the wrong size.
What size rim does a 2024 Jeep Trucks Grand Wagoneer use?
A 2024 Jeep Trucks Grand Wagoneer uses either a 20-inch or 22-inch rim, depending on the tire size fitted to the vehicle. The 275/55R20 size belongs on a 20-inch rim, and the 285/45R22 size belongs on a 22-inch rim. Both fitments use radial tire construction.
Rim diameter is the first thing to confirm because a 20-inch tire cannot be mounted on a 22-inch wheel, and the reverse is also true. The Base model can appear with either diameter, so it is especially important to inspect the wheel itself or read the existing tire sidewall rather than relying only on trim name.
Do all 2024 Jeep Trucks Grand Wagoneer sub-models use the same tire size?
No, not all 2024 Jeep Trucks Grand Wagoneer sub-models use the same tire size. Obsidian, Series III, and Series III Obsidian use 285/45R22, while the Base model can use either 275/55R20 or 285/45R22. That means sub-model and wheel setup both affect the correct replacement size.
This matters because the right tire is tied to the actual wheel package on the vehicle, not just the Grand Wagoneer name. If the SUV is a Base trim, check whether it has 20-inch or 22-inch wheels before moving forward. On the other trims, the 22-inch fitment is the one to match unless the vehicle has been changed from its expected setup.
Choosing the Right Tire
What should I consider when choosing a tire for a 2024 Jeep Trucks Grand Wagoneer?
Start with the correct size for the vehicle’s actual wheel setup: 275/55R20 or 285/45R22. From there, focus on matching the intended use of a full-size luxury SUV, including ride quality expectations, seasonal driving needs, and whether the vehicle is kept in original-style trim or has aftermarket wheel changes.
A careful selection should also account for the exact sub-model, because the Base trim can use either size while the other covered trims use 285/45R22. Once size is confirmed, compare the replacement tire’s fitment characteristics against the existing wheel package and inspect the current tires for uneven wear that could point to alignment or suspension issues.
How do I choose between the available 2024 Jeep Trucks Grand Wagoneer tire sizes?
The two sizes are not interchangeable options for casual preference; they are tied to specific wheel diameters and trim configurations. A 2024 Jeep Trucks Grand Wagoneer with 20-inch wheels uses 275/55R20, while a vehicle with 22-inch wheels uses 285/45R22. The Base model is the one most likely to require a closer check.
The best way to choose is to confirm the wheel diameter on the vehicle before shopping for tires. Reading the current sidewall, inspecting the wheel itself, and verifying whether the SUV still has its intended setup will keep the choice grounded in fitment rather than appearance alone. That is especially important if the vehicle has changed hands or has been modified.
What tire size should I use for my 2024 Jeep Trucks Grand Wagoneer Base?
The 2024 Jeep Trucks Grand Wagoneer Base can use either 275/55R20 or 285/45R22. Both are radial sizes, but the correct one depends on which wheels are actually on the vehicle. Unlike the other covered sub-models, the Base trim is not tied to only one primary size.
That makes a visual and physical check important before replacement. Look at the current tire sidewall and confirm whether the vehicle is equipped with 20-inch or 22-inch wheels. Once that is established, stay with the matching size unless a qualified tire professional has evaluated any wheel, suspension, or clearance changes that might affect replacement fitment.
Restoration & Appearance
Does correct tire fitment matter for a 2024 Jeep Trucks Grand Wagoneer?
Yes, correct tire fitment matters because the 2024 Jeep Trucks Grand Wagoneer uses two distinct wheel-and-tire combinations. The wrong size can create immediate mounting problems at the wheel and can also affect the vehicle’s stance, appearance, and the way the wheel package fills the fender openings.
Even on a modern luxury SUV, appearance and fitment go together. A Grand Wagoneer set up on 20-inch wheels should retain the 275/55R20 fitment, while a 22-inch vehicle should remain with 285/45R22 unless the complete setup has been re-engineered. Buyers who want to preserve the intended look should confirm wheel diameter before making any tire change.
How does tire size affect the appearance of a 2024 Jeep Trucks Grand Wagoneer?
Tire size changes the visual balance of the 2024 Jeep Trucks Grand Wagoneer because each fitment is paired with a different wheel diameter. The 275/55R20 setup is built around a 20-inch wheel, while the 285/45R22 setup is built around a 22-inch wheel. That alone changes the wheel-to-sidewall presentation.
On a large premium SUV, those visual proportions are part of the vehicle’s character, so matching the tire to the correct wheel package helps preserve the intended look. Appearance should not override fitment, though. Before making a change for style reasons, confirm wheel dimensions, current clearance, and whether the vehicle still retains its original-style wheel setup.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2024 Jeep Trucks Grand Wagoneer?
Yes, modifications can affect tire fitment on a 2024 Jeep Trucks Grand Wagoneer. Aftermarket wheels, suspension changes, leveling or lowering adjustments, and body alterations can all change the space available for the tire and may also alter the wheel dimensions needed for a proper match.
That means the correct factory-style size still needs to be checked against the vehicle’s current setup if anything has been changed. A Base model is especially worth verifying because it can use either 20-inch or 22-inch fitment. Clearance at full steering lock, wheel width, and any signs of rubbing should be reviewed before putting replacement tires into service.
What should I inspect before driving a 2024 Jeep Trucks Grand Wagoneer on new tires?
Before driving a 2024 Jeep Trucks Grand Wagoneer on new tires, inspect the wheels for damage, confirm the tire size matches the actual wheel diameter, and make sure the tires are properly inflated. It is also smart to look over suspension and steering components if the previous tires showed uneven wear or unusual handling behavior.
A short visual check can prevent bigger problems on the road. Look for adequate clearance around the fenders and inner wheel areas, especially if the SUV has non-stock wheels or suspension changes. After installation, monitor air pressure, pay attention to vibration, and recheck the tires after the first miles to catch any early fitment or mounting issues.
What should I check before a longer drive in a 2024 Jeep Trucks Grand Wagoneer?
Before a longer drive, confirm that the 2024 Jeep Trucks Grand Wagoneer is riding on the correct size for its wheel setup, either 275/55R20 or 285/45R22, and inspect each tire for visible damage. Sidewall cuts, bulges, irregular wear, and low pressure are all warning signs worth addressing before highway use.
Longer trips also make it worthwhile to check overall condition beyond the tread itself. Make sure the wheels are free of obvious damage, verify that the tires are holding air consistently, and pay attention to any change in ride feel or steering response during the first part of the drive. Any vibration or rubbing should be investigated before continuing.
