The 2022 Jeep Trucks Grand Wagoneer brought the Wagoneer name back as a full-size luxury SUV with a strong emphasis on size, presence, and long-distance comfort. It sits in a modern part of the market where wheel and tire choice shape both the look of the vehicle and the way it fills the wheel openings. For this exact model, fitment centers on radial tires in either 275/55R20 or 285/45R22, depending on sub-model and wheel package. That makes the key decision less about vintage construction and more about confirming the correct rim diameter first. Buyers should match the tire to the vehicle's exact trim and wheel setup before comparing replacement options.
Which Tire Size Is Right for The 2022 Jeep Trucks Grand Wagoneer
The 2022 Jeep Trucks Grand Wagoneer uses two primary tire sizes, and the first step is confirming whether the vehicle is equipped with 20-inch or 22-inch wheels. Both sizes are radial metric fitments, but they apply differently across the Grand Wagoneer lineup, so identifying the exact sub-model and actual wheel diameter matters before choosing a replacement tire.
Fit(s): Obsidian, Series I, Series II, and Series III
Construction: Radial|Rim: 22 in
285/45R22 is a metric radial size in which 285 refers to the section width in millimeters, 45 is the aspect ratio, R identifies radial construction, and 22 is the rim diameter in inches. On the 2022 Jeep Trucks Grand Wagoneer, this size suits configurations built around a large-diameter 22-inch wheel and a lower-profile modern luxury SUV look. Its overall dimensions help explain why wheel confirmation is so important before replacement. This is the size to evaluate when the vehicle is equipped with the larger factory-style wheel package rather than the 20-inch setup.
275/55R20 is a metric radial size where 275 is the section width in millimeters, 55 is the aspect ratio, R denotes radial construction, and 20 is the rim diameter in inches. On the 2022 Jeep Trucks Grand Wagoneer, this size is associated with a 20-inch wheel configuration rather than the larger 22-inch setup. Its sidewall profile and wheel pairing make it a distinct fitment choice, not just a cosmetic variation. This is the size to confirm when checking a Series I model or any Grand Wagoneer that has 20-inch wheels installed.
Grand Wagoneer sub-model fitment is not completely uniform, because some versions use 22-inch wheels while Series I can appear with either 20-inch or 22-inch tire fitment. Checking the exact sub-model and then verifying the wheel diameter on the vehicle is the cleanest way to avoid selecting the wrong size.

2022 Jeep Trucks Grand Wagoneer Obsidian
The 2022 Jeep Trucks Grand Wagoneer Obsidian uses the 285/45R22 radial size. Tire selection here starts with maintaining the correct 22-inch fitment and then choosing a replacement that matches the vehicle's wheel setup and intended road use.
The 2022 Jeep Trucks Grand Wagoneer Series I is the sub-model that requires the closest attention, because it appears with either 275/55R20 or 285/45R22 radial fitment. Tire choice depends on confirming which wheel diameter is actually on the vehicle before comparing replacement options.
The 2022 Jeep Trucks Grand Wagoneer Series II uses the 285/45R22 radial size. That keeps the buying decision focused on proper 22-inch replacement fitment and on checking that the vehicle still carries its intended wheel package.
The 2022 Jeep Trucks Grand Wagoneer Series III uses the 285/45R22 radial size. For this sub-model, the practical next step is confirming the 22-inch wheel setup and selecting a tire that matches the vehicle's current configuration.
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)

Frequently Asked Questions
These FAQs focus on the two tire sizes used on the 2022 Jeep Trucks Grand Wagoneer, how sub-model fitment changes, and what to verify around wheel diameter, tire selection, maintenance, and road-use readiness.
Tire Size & Fitment
What tire size fits a 2022 Jeep Trucks Grand Wagoneer?
The 2022 Jeep Trucks Grand Wagoneer uses either 285/45R22 or 275/55R20 tires, depending on the sub-model and wheel setup. Both are radial metric sizes, and they are not interchangeable as a basic size choice because they are built around different rim diameters.
The most important step is checking the actual wheel diameter on the vehicle before ordering replacement tires. Most Grand Wagoneer sub-models use 285/45R22, while Series I can use either size, so trim level alone should be confirmed against the wheels currently installed.
What size rim does a 2022 Jeep Trucks Grand Wagoneer use?
A 2022 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 tire is built for a 20-inch rim, while the 285/45R22 tire is built for a 22-inch rim.
That difference matters because tire selection starts with rim diameter, not just with the model name. Checking the sidewall marking and measuring the actual wheel setup is especially important on Series I models, since that sub-model appears with both 20-inch and 22-inch fitment.
Do all 2022 Jeep Trucks Grand Wagoneer sub-models use the same tire size?
No, not all 2022 Jeep Trucks Grand Wagoneer sub-models use the same tire size. Obsidian, Series II, and Series III use 285/45R22, while Series I can use either 275/55R20 or 285/45R22 depending on its wheel configuration.
That means the exact sub-model helps narrow the search, but the wheel diameter still needs to be verified on the vehicle itself. A Grand Wagoneer that has had wheel changes since new should always be checked carefully before replacement tires are selected.
Choosing the Right Tire
What should I consider when choosing a tire for a 2022 Jeep Trucks Grand Wagoneer?
Start with the correct size: 275/55R20 or 285/45R22, depending on the wheel setup and sub-model. The Grand Wagoneer uses radial metric fitment, so the main selection factors are correct rim diameter, overall compatibility with the existing wheel package, and the type of road use the vehicle sees.
A replacement tire should match the vehicle's current wheel setup without guessing across sizes. Owners should also consider whether the Grand Wagoneer still wears its original-style wheels or has been changed, since aftermarket wheel swaps can alter width, clearance, and the proper tire choice.
How do I choose between the available 2022 Jeep Trucks Grand Wagoneer tire sizes?
The choice between 275/55R20 and 285/45R22 is determined by the wheel diameter already on the vehicle, not by preference alone. A Grand Wagoneer with 20-inch wheels uses the 275/55R20 size, while a vehicle with 22-inch wheels uses the 285/45R22 size.
The practical difference is that each size is built around a different rim, so switching between them involves more than changing the tire itself. Verifying the exact wheel package is especially important on Series I models, where both fitments appear within the same sub-model range.
What rim-fitment details should I compare when choosing 2022 Jeep Trucks Grand Wagoneer tires?
The first rim-fitment detail to compare is diameter, since this Grand Wagoneer uses either a 20-inch or 22-inch wheel. After that, the tire size on the sidewall should match the wheel setup already on the vehicle so the replacement stays aligned with the intended fitment.
It also helps to inspect the actual wheel package closely if the vehicle was purchased used or has been customized. Changes in wheel width or aftermarket styling can affect how a tire sits and clears, even when the vehicle is still wearing one of the two correct base sizes.
Restoration & Appearance
Does correct tire fitment matter for a 2022 Jeep Trucks Grand Wagoneer restoration or appearance refresh?
Yes, correct tire fitment matters because the 2022 Jeep Trucks Grand Wagoneer was styled around large modern wheel and tire proportions. Using the wrong size can change how the SUV sits visually and can create avoidable issues when replacing tires on either the 20-inch or 22-inch setup.
Appearance-focused buyers should begin by preserving the wheel diameter and tire size that belong on the vehicle's actual configuration. That approach keeps the proportions closer to the intended presentation and avoids turning a cosmetic update into a fitment problem.
Which tire size should I keep for the intended look of a 2022 Jeep Trucks Grand Wagoneer?
The intended look of a 2022 Jeep Trucks Grand Wagoneer is tied closely to whether it uses 275/55R20 or 285/45R22. The 22-inch fitment delivers the larger-wheel presentation seen on most covered sub-models, while the 20-inch fitment belongs to certain Series I configurations.
Keeping the existing correct size is usually the most straightforward way to preserve the vehicle's proportions. A buyer focused on appearance should confirm the sub-model and the actual wheel diameter first, especially if the vehicle has changed hands or may have had wheel swaps.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2022 Jeep Trucks Grand Wagoneer?
Yes, modifications can affect tire fitment on a 2022 Jeep Trucks Grand Wagoneer even when the vehicle started with one of the correct base sizes. Changes to wheels, suspension height, or body clearance can alter how a 275/55R20 or 285/45R22 tire sits and moves in the wheel opening.
A Grand Wagoneer with aftermarket wheels should be checked for actual rim diameter and overall compatibility before replacement tires are chosen. Clearance around fenders, steering travel, and suspension movement is worth inspecting anytime the vehicle no longer carries its original wheel and suspension setup.
What should I inspect before driving a 2022 Jeep Trucks Grand Wagoneer on new tires?
Before road use, inspect the wheel and tire installation carefully and confirm that the tire size matches the vehicle's actual wheel diameter. A 2022 Jeep Trucks Grand Wagoneer should also be checked for proper inflation, secure wheel hardware, and even seating of the tire on the rim.
It is also smart to look for any interference during steering and suspension movement, especially if the vehicle has aftermarket wheels or previous modifications. A short initial drive followed by a recheck for pressure loss, vibration, or rubbing can catch issues early.
How often should tires on a 2022 Jeep Trucks Grand Wagoneer be inspected?
Tires on a 2022 Jeep Trucks Grand Wagoneer should be inspected regularly, not just when replacement time arrives. Frequent checks for pressure loss, uneven wear, sidewall damage, cuts, and tread condition help catch problems before they affect ride quality or road manners.
Vehicles that see long highway trips, sit for stretches, or carry heavy passenger loads deserve especially consistent attention. It also helps to inspect the tires before longer drives and after any curb impact or road hazard, since large-diameter wheel packages can make damage easier to overlook at a glance.
