The 2023 Jeep Trucks Grand Wagoneer brings the Wagoneer name into the modern full-size luxury SUV world, blending three-row utility with upscale road manners and a substantial visual presence. Owners typically approach tire replacement with a mix of daily-use expectations, highway comfort concerns, and a desire to preserve the vehicle’s premium stance. For this model, the key fitment question centers on two radial tire sizes, 275/55R20 and 285/45R22, depending on wheel setup and sub-model. That makes the real decision less about old-versus-new construction and more about confirming the exact wheel package in place before choosing the right tire. Appearance, ride character, and wheel compatibility all matter here.
Which Tire Size Is Right for The 2023 Jeep Trucks Grand Wagoneer
The 2023 Jeep Trucks Grand Wagoneer uses two primary tire sizes, and the correct one depends on the exact sub-model and wheel package. Both are radial metric sizes, but they mount on different rim diameters, so the first step is confirming whether the vehicle has 20-inch or 22-inch wheels before comparing tire choices.
A 275/55R20 tire uses a 275-millimeter nominal section width, a 55-series aspect ratio, radial construction, and a 20-inch rim. On the 2023 Jeep Trucks Grand Wagoneer, this size suits configurations equipped with the 20-inch wheel setup and carries the balanced, modern fitment language expected on a luxury full-size SUV. Its dimensions place it close to the larger 22-inch package in overall height, but wheel diameter remains the deciding factor. This size is the one to evaluate when the vehicle keeps its 20-inch wheels and the goal is to match that original wheel-and-tire format correctly.
Fit(s): Base, Obsidian, Series II, Series III, and Series III Obsidian
Construction: Radial|Rim: 22 in
A 285/45R22 tire has a 285-millimeter nominal section width, a 45-series aspect ratio, radial construction, and a 22-inch rim. On the 2023 Jeep Trucks Grand Wagoneer, this size is used on the 22-inch wheel configurations and is the more widely shared fitment across the named sub-models. The lower profile relative to the 20-inch package works with the larger wheel diameter to create a more substantial wheel presentation without changing the tire category. This is the size to confirm when the vehicle is equipped with factory-style or equivalent 22-inch wheels and replacement needs to follow that setup.
Sub-model fitment matters on the 2023 Jeep Trucks Grand Wagoneer because not every version uses the same wheel and tire setup. The Base model can be found with either primary size, while the Obsidian, Series II, Series III, and Series III Obsidian use the 22-inch fitment.

2023 Jeep Trucks Grand Wagoneer Base
The 2023 Jeep Trucks Grand Wagoneer Base can use either of the two primary radial tire sizes, which makes wheel confirmation especially important on this trim. Tire selection starts with verifying whether the vehicle has the 20-inch or 22-inch setup before moving on to brand, tread style, or other replacement preferences.
The 2023 Jeep Trucks Grand Wagoneer Obsidian uses the 285/45R22 radial fitment. That keeps replacement selection straightforward, with the main task being confirmation that the vehicle still wears the correct 22-inch wheel package and has not been changed to an aftermarket setup.
The 2023 Jeep Trucks Grand Wagoneer Series II uses the 285/45R22 radial tire size. For replacement, the focus is on staying with the proper 22-inch wheel fitment and checking that wheel width, load suitability, and overall clearance remain appropriate if anything has been modified.
The 2023 Jeep Trucks Grand Wagoneer Series III uses the 285/45R22 radial size. That means the buyer is not choosing between primary tire sizes on this sub-model, but still needs to confirm the existing wheel setup and compare replacement options that suit a premium, road-oriented SUV.
2023 Jeep Trucks Grand Wagoneer Series III Obsidian
The 2023 Jeep Trucks Grand Wagoneer Series III Obsidian uses the 285/45R22 radial fitment. Tire shopping for this version is mainly about selecting the right replacement within that size and verifying that any wheel or suspension changes have not altered the vehicle’s original fitment requirements.
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 2023 Jeep Trucks Grand Wagoneer usually need clarity on the correct tire size, wheel diameter, sub-model differences, and what to inspect before replacing tires on a modern luxury SUV with either 20-inch or 22-inch fitment.
Tire Size & Fitment
What tire size fits a 2023 Jeep Trucks Grand Wagoneer?
The 2023 Jeep Trucks Grand Wagoneer uses two primary tire sizes: 275/55R20 and 285/45R22. Both are radial metric sizes, but they are not interchangeable as primary fitments because they mount on different wheel diameters and appear on different Grand Wagoneer configurations.
The correct choice starts with identifying the exact sub-model and then confirming the wheel diameter actually on the vehicle. The Base model can use either size, while the Obsidian, Series II, Series III, and Series III Obsidian use 285/45R22, so checking the tire sidewall or wheel package before ordering is the safest next step.
What size rim does a 2023 Jeep Trucks Grand Wagoneer use?
A 2023 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 uses a 20-inch rim, while the 285/45R22 size uses a 22-inch rim.
Rim diameter is the first fitment detail to verify because the two tire sizes belong to different wheel packages. Looking at the tire sidewall is usually the quickest way to confirm what is currently installed, and that should be checked before comparing replacement tires, especially on Base models that may have either setup.
Why does the 2023 Jeep Trucks Grand Wagoneer have more than one tire size?
The 2023 Jeep Trucks Grand Wagoneer has more than one tire size because different sub-models and wheel packages use different fitments. The model range includes a 20-inch setup with 275/55R20 and a 22-inch setup with 285/45R22, with the Base trim spanning both possibilities.
That means tire selection is tied to how the specific vehicle was equipped rather than to the model name alone. A buyer should verify the exact sub-model and wheel diameter first, then match the replacement tire to the existing wheel package instead of assuming every Grand Wagoneer in this model year uses the same size.
Choosing the Right Tire
What should I consider when choosing a tire for a 2023 Jeep Trucks Grand Wagoneer?
Start with the correct primary size for the vehicle: 275/55R20 or 285/45R22. On a 2023 Jeep Trucks Grand Wagoneer, the most important selection factors are the exact wheel diameter on the vehicle, the correct radial size format, and whether the tire matches the intended daily road use of a large luxury SUV.
After size is confirmed, compare the replacement tire’s fitment details against the wheel package already in place and consider whether the vehicle has remained stock. That is especially important on Base models, since either primary size may apply, and on any vehicle that may have seen aftermarket wheel, suspension, or appearance changes.
How do I choose between the available 2023 Jeep Trucks Grand Wagoneer tire sizes?
The two available tire sizes are not a matter of preference alone, because each belongs to a different rim diameter. A 2023 Jeep Trucks Grand Wagoneer with 20-inch wheels uses 275/55R20, while one with 22-inch wheels uses 285/45R22, so the wheel package determines the starting point.
Once the rim diameter is confirmed, the buying decision becomes much simpler. Instead of comparing the two primary sizes against each other, compare replacement options within the correct size and make sure the vehicle still has the wheel setup, clearance, and suspension condition appropriate for that fitment.
How do I choose between the available radial tires for a 2023 Jeep Trucks Grand Wagoneer?
Choosing a radial tire for a 2023 Jeep Trucks Grand Wagoneer begins with matching the exact size already required by the wheel package. Since both primary fitments are radial, the decision is not about changing construction type but about selecting the right replacement within either 275/55R20 or 285/45R22.
A careful buyer should confirm the existing wheel diameter, inspect the current tire sidewall, and note whether the vehicle has been altered from stock. From there, compare replacement options in the proper size with attention to how the SUV is used, whether that means everyday road service, family travel, or long-distance highway driving.
Restoration & Appearance
Does correct tire fitment matter for a 2023 Jeep Trucks Grand Wagoneer restoration or appearance-focused build?
Yes. Even on a modern vehicle like the 2023 Jeep Trucks Grand Wagoneer, correct tire fitment strongly affects stance, wheel-to-tire proportion, and the overall appearance of the SUV. Using the proper 275/55R20 or 285/45R22 size helps preserve the visual balance intended for the wheel package actually fitted to the vehicle.
Appearance-focused builds still need to start with wheel diameter and real clearance, not styling alone. A Grand Wagoneer that has been modified with different wheels or suspension parts may need additional checks, and anyone pursuing a highly exact presentation should compare the vehicle’s current setup against marque-specific references and original build details.
Which tire size should I keep for a factory-inspired 2023 Jeep Trucks Grand Wagoneer appearance?
For a factory-inspired appearance, keep the same primary tire size that matches the wheel package on the vehicle. That means 275/55R20 on the 20-inch setup or 285/45R22 on the 22-inch setup, with the Base model requiring extra attention because it can be found with either fitment.
Maintaining that original size relationship usually preserves the intended wheel opening fill and overall visual proportion better than jumping to a different fitment without a full wheel-and-clearance review. It is also wise to confirm that the current wheels are the correct diameter before replacing tires, especially if the Grand Wagoneer was purchased used.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2023 Jeep Trucks Grand Wagoneer?
Yes. Modifications can affect tire fitment on a 2023 Jeep Trucks Grand Wagoneer even when the replacement tire matches one of the primary sizes. Aftermarket wheels, suspension changes, leveling kits, lowering, or body alterations can change the available clearance and the relationship between the tire and wheel opening.
That matters most when the vehicle no longer matches its original wheel package. A modified Grand Wagoneer should be checked for wheel diameter, wheel width, offset, suspension travel, and turning clearance before new tires are installed, rather than assuming that a size associated with the model year will behave the same on every example.
What should I inspect before driving a 2023 Jeep Trucks Grand Wagoneer on new tires?
Before driving, inspect the wheel diameter, confirm the installed tire size, and make sure each tire is seated properly and inflated to the vehicle’s required specification. It is also smart to look over the wheels for damage and make sure lug hardware, alignment condition, and valve components are all in proper shape.
A short post-installation check is worthwhile as well. Watch for rubbing at full steering lock, listen for unusual noise, and recheck pressure after the first few drives, especially if the Grand Wagoneer has 22-inch wheels or any aftermarket parts that could influence clearance, ride behavior, or tire wear.
How often should tires on a 2023 Jeep Trucks Grand Wagoneer be inspected?
Tires on a 2023 Jeep Trucks Grand Wagoneer should be inspected regularly, not only when tread appears worn. A quick visual check every few weeks and a more careful inspection before longer trips helps catch uneven wear, cuts, punctures, bulges, and pressure loss before they become more serious issues.
Regular inspection matters because this is a large, heavy SUV that may see highway use, passengers, and cargo. Looking closely at both the tread and sidewalls, while also keeping an eye on pressure consistency, makes it easier to spot alignment issues or wheel damage early and helps keep the correct 20-inch or 22-inch setup performing as intended.
