The 2022 Jeep Trucks Grand Cherokee L brought three-row space into the Grand Cherokee line while keeping the model’s upscale SUV character and broad trim spread. That matters for tire fitment, because this exact vehicle can use three different radial sizes depending on sub-model and wheel package: 265/60R18, 265/50R20, or 275/45R21. The choice is less about vintage construction and more about confirming the correct trim and wheel diameter before comparing replacement tires. On a Grand Cherokee L, that means balancing factory-style appearance, everyday road use, and the practical realities of wheel size, sidewall height, and clearance on the vehicle you actually own.
Which Tire Size Is Right for The 2022 Jeep Trucks Grand Cherokee L
The 2022 Jeep Trucks Grand Cherokee L uses three primary tire sizes, and the right one depends on the exact sub-model and wheel diameter. All three are radial fitments, but they are tied to 18-inch, 20-inch, or 21-inch wheels, so the first step is confirming the trim and checking the wheels currently on the vehicle before choosing a replacement tire.
A 265/50R20 tire uses a 265-millimeter section width, a 50-series aspect ratio, radial construction, and a 20-inch rim. On the 2022 Jeep Trucks Grand Cherokee L, this size is one of the common fitments and appears across several sub-models with 20-inch wheels. Its proportions give the vehicle a modern SUV stance while keeping overall diameter close to the other factory sizes used on this model. This is the size to evaluate when the Grand Cherokee L is equipped with a 20-inch wheel package and you want to stay with the intended fitment range for that setup.
A 265/60R18 tire keeps the same 265-millimeter nominal width as the 20-inch option, but uses a taller 60-series sidewall on an 18-inch rim. That makes it a true metric radial format with a different wheel relationship, not just a minor variation of the 20-inch fitment. On the 2022 Jeep Trucks Grand Cherokee L, this size is tied to specific sub-models and wheel packages that use 18-inch wheels. It is the size to consider when wheel diameter points clearly to the 18-inch setup and you want to avoid confusion with the visually similar 265-width alternatives.
A 275/45R21 tire combines a wider 275-millimeter section width with a 45-series profile and radial construction on a 21-inch rim. Within the 2022 Jeep Trucks Grand Cherokee L range, this size belongs to the larger-wheel configuration used on upper trims and delivers a distinctly different wheel-and-tire package from the 18-inch and 20-inch fitments. The lower-profile sidewall and 21-inch wheel requirement make wheel confirmation especially important before replacement. This is the correct direction to explore when the vehicle is already equipped with the 21-inch setup rather than a smaller factory wheel package.
Tire fitment varies across the 2022 Jeep Trucks Grand Cherokee L lineup, and some sub-models can be found with more than one factory-size path depending on wheel package. Checking the exact trim and the wheel diameter on the vehicle is the quickest way to avoid choosing the wrong tire.

2022 Jeep Trucks Grand Cherokee L Altitude
The 2022 Jeep Trucks Grand Cherokee L Altitude uses a single radial tire fitment tied to its 20-inch wheel setup. Tire selection is therefore more straightforward here, with the main job being to confirm that the vehicle still carries its correct wheel package before ordering replacements.
The 2022 Jeep Trucks Grand Cherokee L Laredo uses the 18-inch wheel and tire configuration rather than the larger-wheel alternatives found elsewhere in the range. That makes wheel-diameter verification especially important if the vehicle has changed hands or has been updated with aftermarket wheels.
The 2022 Jeep Trucks Grand Cherokee L Limited can use either the 18-inch or 20-inch radial fitment depending on how the vehicle is equipped. Tire selection starts with confirming which wheel package is actually on the SUV, since both sizes belong to this sub-model.
The 2022 Jeep Trucks Grand Cherokee L Overland (AWD) appears with both 18-inch and 20-inch radial tire paths. That means the sub-model name alone is not enough; the wheel diameter on the vehicle needs to be checked before comparing replacement tires.
The 2022 Jeep Trucks Grand Cherokee L Overland (RWD) uses the 20-inch radial setup rather than the broader mix seen on some other trims. Replacement shopping is simpler once the existing wheels are confirmed to be the correct 20-inch configuration.
The 2022 Jeep Trucks Grand Cherokee L Summit can be equipped with either a 20-inch or 21-inch radial tire fitment. That makes wheel confirmation the key step, since the two Summit tire sizes are not interchangeable choices without matching wheel diameter.
The 2022 Jeep Trucks Grand Cherokee L Summit Reserve uses the 21-inch radial fitment associated with the largest factory wheel package in this model range. Tire replacement should stay focused on that 21-inch setup unless the vehicle has been deliberately converted to a different wheel package.
2022 Jeep Trucks Grand Cherokee L Summit Reserve V8 4x4
The 2022 Jeep Trucks Grand Cherokee L Summit Reserve V8 4x4 uses the 21-inch radial tire package. The practical takeaway is to confirm that the SUV still has its 21-inch wheels in place, then shop within that size rather than comparing it to the smaller-wheel Grand Cherokee L trims.
The 2022 Jeep Trucks Grand Cherokee L Summit V8 4x4 can use either the 20-inch or 21-inch radial fitment depending on wheel package. Choosing correctly starts with the wheels on the vehicle now, since both sizes belong to this sub-model and lead to different replacement paths.
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
Grand Cherokee L owners usually need to confirm trim, wheel diameter, and the correct metric radial size before replacing tires. The questions below focus on size meaning, sub-model variation, wheel fitment, tire selection, and road-use checks.
Tire Size & Fitment
What tire size fits a 2022 Jeep Trucks Grand Cherokee L?
The 2022 Jeep Trucks Grand Cherokee L uses three primary tire sizes: 265/60R18, 265/50R20, and 275/45R21. All are radial sizes, and the correct one depends on the exact sub-model and wheel package rather than the model name alone.
The most important next step is confirming the wheel diameter on the vehicle, because an 18-inch, 20-inch, or 21-inch tire must match the same rim diameter. Some trims, including Limited, Overland (AWD), Summit, and Summit V8 4x4, can be found with more than one factory-size path, so checking the tire sidewall and the wheels themselves helps prevent ordering the wrong size.
What size rim does a 2022 Jeep Trucks Grand Cherokee L use?
A 2022 Jeep Trucks Grand Cherokee L can use 18-inch, 20-inch, or 21-inch rims depending on trim and wheel package. Those rim diameters correspond to the three factory tire sizes used on this model: 265/60R18, 265/50R20, and 275/45R21.
Rim diameter matters because the last number in the tire size must match the wheel exactly. A 20-inch tire cannot be mounted on an 18-inch or 21-inch wheel, even if the overall tire height looks similar. On trims with more than one valid factory setup, checking the current wheel size is more useful than relying on trim name alone.
Why does the 2022 Jeep Trucks Grand Cherokee L have more than one tire size?
The 2022 Jeep Trucks Grand Cherokee L has more than one tire size because the model range spans several trims and wheel packages. Some versions use 18-inch wheels, others use 20-inch wheels, and upper trims can use a 21-inch package, which changes the tire size needed.
That does not mean all three sizes are interchangeable on the same vehicle. Each size is tied to a specific wheel diameter, and some sub-models were available with more than one factory arrangement. The practical approach is to identify the exact trim, then verify the actual wheels on the SUV, especially if it was purchased used or has been modified.
Choosing the Right Tire
What should I consider when choosing a 2022 Jeep Trucks Grand Cherokee L tire?
Start with the correct size for the exact sub-model and wheel package: 265/60R18, 265/50R20, or 275/45R21. On this Grand Cherokee L, the main decision is not bias-ply versus radial, since all primary fitments are radial, but making sure the replacement matches the wheel diameter and intended setup.
After size confirmation, compare the replacement tire’s overall use case with how the SUV is driven. A family road-trip vehicle, daily commuter, and lightly used second vehicle may all place different priorities on ride feel and appearance. It also helps to confirm that all four tires match in size and that the wheels have not been changed from the original package.
How do I choose between the available 265/50R20, 265/60R18, and 275/45R21 tires for a 2022 Jeep Trucks Grand Cherokee L?
The choice between those sizes is made by vehicle configuration, not preference alone. A 2022 Jeep Trucks Grand Cherokee L fitted with 18-inch wheels needs 265/60R18, a 20-inch setup uses 265/50R20, and a 21-inch setup uses 275/45R21.
Once the correct size is established, compare tires within that one size instead of cross-shopping the other factory fitments. This keeps the focus on the wheel package already on the vehicle and avoids mixing sizes that require different rims. If the SUV has changed owners or received aftermarket wheels, reading the current tire sidewall and measuring wheel diameter are worthwhile checks.
How do I choose between the available tires for my 2022 Jeep Trucks Grand Cherokee L sub-model?
Begin with the sub-model and then confirm the wheels currently on the vehicle. That step matters most on Limited, Overland (AWD), Summit, and Summit V8 4x4 models, since those trims can use more than one factory tire size depending on wheel package.
After that, keep the replacement search confined to the exact size already matched to the vehicle’s rims. This avoids turning a trim-level question into a guessing exercise. If the Grand Cherokee L has aftermarket wheels, suspension changes, or a mixed set from a previous owner, use the actual wheel diameter and existing fitment as the starting point rather than the badge alone.
Restoration & Appearance
Does correct tire fitment matter for a 2022 Jeep Trucks Grand Cherokee L restoration or appearance refresh?
Yes. Even on a modern SUV like the 2022 Jeep Trucks Grand Cherokee L, the correct tire size has a strong effect on stance, wheel-to-sidewall proportion, and the overall look of the vehicle. Staying with the proper 18-inch, 20-inch, or 21-inch fitment keeps the appearance aligned with the wheel package the SUV was built around.
Appearance work can go off track quickly when tire size is chosen by guesswork rather than by trim and wheel confirmation. A tire that belongs to a different wheel package can change visual balance and complicate fitment at the same time. Owners aiming for a clean factory-style presentation should confirm the original wheel setup before replacing tires.
Which tire should I choose for a factory-style 2022 Jeep Trucks Grand Cherokee L appearance?
A factory-style appearance starts with the same primary tire size and wheel diameter used by the specific Grand Cherokee L sub-model. That means choosing 265/60R18, 265/50R20, or 275/45R21 according to the vehicle’s actual trim and wheel package rather than moving to another factory size for cosmetic reasons alone.
On this model, the visual character changes with the wheel package, so tire selection should support the setup already on the SUV. Confirming the current wheels is especially important on trims that can use more than one fitment path. For owners pursuing a very exact presentation, original window-sticker or build information can help verify how the vehicle was equipped.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2022 Jeep Trucks Grand Cherokee L?
Yes. Modifications can affect tire fitment on a 2022 Jeep Trucks Grand Cherokee L even when the tire size is one of the factory sizes. Aftermarket wheels, changes in wheel width or offset, suspension lowering, lift changes, or body alterations can all change how much room the tire has at the fender, suspension, and steering components.
That is why a replacement should be matched not only to the trim but also to the vehicle’s current setup. A used Grand Cherokee L may no longer have its original wheels, and even small changes can alter clearance. Turning the steering from lock to lock and checking loaded ride height are sensible steps before committing to a replacement size.
What should I inspect before driving a 2022 Jeep Trucks Grand Cherokee L on new tires?
Before driving on new tires, check that all four tires are the correct size for the wheel package, properly mounted, and inflated to the vehicle’s required pressure. It is also smart to inspect the wheels for damage and confirm that there is no rubbing at the inner fender, suspension, or steering components.
A short, careful road test can reveal vibration, pull, or unexpected contact that may not be obvious at a standstill. Rechecking pressure after installation is worthwhile, especially if the SUV has been sitting or the weather has changed. On a Grand Cherokee L with recent wheel or suspension changes, a final clearance review is time well spent.
How often should tires on a 2022 Jeep Trucks Grand Cherokee L be inspected?
Tires on a 2022 Jeep Trucks Grand Cherokee L should be inspected regularly, not just when tread looks low. A visual check for uneven wear, cuts, punctures, bulges, and sidewall damage is a good routine habit, and pressure should be monitored consistently because a large SUV depends on stable inflation for proper road behavior.
Monthly checks are a sensible baseline, with another inspection before longer trips or heavy seasonal use. It also helps to look for signs that suggest alignment or suspension issues, especially if one edge is wearing faster than the rest of the tread. Catching those problems early can protect both the new tires and the vehicle’s ride quality.
