The 2023 Jeep Trucks Grand Cherokee sits at the modern end of the nameplate’s long move from traditional SUV roots into a more refined, multi-trim family that still spans everyday driving, upscale touring, and electrified 4xe use. That broad trim range matters because this exact model uses four primary radial tire sizes: 245/70R17, 265/60R18, 265/50R20, and 275/45R21. Tire choice here is less about vintage-style construction and more about matching the correct wheel diameter and sub-model setup. Some versions stay with practical 17- or 18-inch fitments, while upper trims move to 20- or 21-inch sizes, so wheel verification comes first before comparing available tire options.
Which Tire Size Is Right for The 2023 Jeep Trucks Grand Cherokee
Four tire sizes apply to the 2023 Jeep Trucks Grand Cherokee, and they do not all use the same wheel diameter. Fitment varies by sub-model, with 17-, 18-, 20-, and 21-inch rim applications across the range. The first step is confirming the exact sub-model and wheel size on the vehicle, especially if it has been changed from its original trim-specific setup.
265/50R20 is a metric radial size in which 265 is the nominal section width in millimeters, 50 is the aspect ratio, R indicates radial construction, and 20 is the rim diameter in inches. On the 2023 Jeep Trucks Grand Cherokee, this size appears across a wide range of trims, making it one of the more common fitments in the lineup. Its lower-profile look relative to taller sidewall sizes gives it a distinctly modern appearance. This is the size to evaluate when the vehicle is equipped with 20-inch wheels and the trim level calls for that setup.
265/60R18 follows the same metric radial sizing system, with a 265-millimeter nominal width, a 60-series profile, radial construction, and an 18-inch rim diameter. This size serves several Grand Cherokee sub-models, including some trims that can also appear with other wheel packages. Compared with a shorter-profile 20- or 21-inch fitment, it keeps more sidewall height while staying in a modern radial format. It deserves a close look when the vehicle has 18-inch wheels and the goal is to match the tire size tied to that exact trim and wheel combination.
245/70R17 is a metric radial size where 245 gives the nominal width in millimeters, 70 identifies the aspect ratio, R means radial, and 17 marks the rim diameter in inches. Within the 2023 Jeep Trucks Grand Cherokee range, this fitment is tied to specific lower-wheel applications rather than the full model lineup. Available product choice in this size includes a BFGoodrich All-Terrain T/A KO2 with raised white letter styling and an all-terrain series character. This size should be matched carefully to the correct 17-inch wheel setup and intended use before making a final selection.
275/45R21 is a metric radial tire size with a 275-millimeter nominal width, a 45-series profile, radial construction, and a 21-inch rim diameter. In the 2023 Jeep Trucks Grand Cherokee range, this fitment is associated with specific upper-end sub-models rather than broad use across the lineup. The shorter sidewall and larger wheel diameter create a distinct trim-specific fitment that should not be confused with the 20-, 18-, or 17-inch options. This is the size to confirm when the vehicle is equipped with 21-inch wheels from the Summit Reserve or related configurations.
Sub-model fitment matters on the 2023 Jeep Trucks Grand Cherokee because tire size changes across the lineup and several trims use more than one wheel package. Identifying the exact sub-model is the most important step before comparing tires, since rim diameter ranges from 17 to 21 inches.

2023 Jeep Trucks Grand Cherokee 30th Anniversary 4xe
The 30th Anniversary 4xe uses the 265/50R20 radial fitment. Tire selection here centers on confirming the 20-inch wheel setup and then choosing a tire that matches the vehicle’s intended road use and overall appearance.
The 4xe appears with either 265/50R20 or 265/60R18, so this trim is not tied to one universal tire size. Wheel diameter should be verified first, especially on vehicles that may have changed wheels since new.
The Altitude uses the 265/50R20 radial size. That keeps the tire search straightforward, with the main task being confirmation of the 20-inch wheel and comparison of tire choices suited to how the vehicle is driven.
The Altitude X can use either 265/50R20 or 265/60R18 depending on the wheel package. Choosing correctly starts with checking the actual wheel diameter on the vehicle rather than relying on trim name alone.
The Laredo uses either 245/70R17 or 265/60R18, making it one of the trims where fitment depends directly on wheel size. Buyers should confirm whether the vehicle carries the 17-inch or 18-inch setup before narrowing the tire search.
The Laredo X uses the 265/60R18 radial size. That makes tire selection simpler than on multi-size trims, though the 18-inch wheel should still be confirmed before comparing available options.
The Limited appears with either 265/50R20 or 265/60R18. The practical difference for the buyer is straightforward: confirm whether the vehicle has 20-inch or 18-inch wheels, then compare tires within that exact size.
The Overland uses the 265/50R20 radial fitment. Tire choice focuses on matching the 20-inch wheel setup and selecting a tire that suits the vehicle’s use without drifting into other Grand Cherokee trim sizes.
The Overland 4xe uses 265/50R20. With a single fitment tied to this sub-model, the main decision becomes choosing the right tire within that size rather than sorting through multiple primary size options.
The Summit uses the 265/50R20 radial size. Selection is mainly about staying with the correct 20-inch fitment and comparing tire characteristics appropriate for the vehicle’s trim and road use.
The Summit 4xe can use either 265/50R20 or 275/45R21, so wheel confirmation is essential on this sub-model. The difference is not minor, since the two fitments use different rim diameters and should be matched carefully to the actual setup.
2023 Jeep Trucks Grand Cherokee Summit Reserve 4xe
The Summit Reserve 4xe uses the 275/45R21 radial fitment. Tire selection should stay focused on the 21-inch wheel application rather than the more common 18- or 20-inch sizes seen elsewhere in the lineup.
The Summit Reserve V6 uses 275/45R21. That makes the fitment path fairly direct, with the buyer’s main task being confirmation of the 21-inch wheel and comparison of tires within that specific size.
The Summit Reserve V8 also uses 275/45R21. Since this is a distinct 21-inch application, the correct tire search begins with wheel verification and stays separate from the smaller-diameter Grand Cherokee fitments.
The Trailhawk 4xe uses the 265/60R18 radial size. That keeps the tire decision centered on the 18-inch wheel package and on choosing a tire that matches the vehicle’s intended driving conditions.
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.
Best 2023 Jeep Trucks Grand Cherokee Tires for Sale
Available product coverage for the 2023 Jeep Trucks Grand Cherokee currently centers on 245/70R17, including a BFGoodrich All-Terrain T/A KO2 radial with raised white letter sidewalls. That gives buyers a focused comparison point for 17-inch applications, especially where all-terrain character matters.
These FAQs focus on the exact tire sizes used on the 2023 Jeep Trucks Grand Cherokee, how fitment changes by sub-model, and what to check when comparing wheel diameter, tire choice, and road-use readiness.
Tire Size & Fitment
What tire size fits a 2023 Jeep Trucks Grand Cherokee?
The 2023 Jeep Trucks Grand Cherokee uses four primary tire sizes: 245/70R17, 265/60R18, 265/50R20, and 275/45R21. These are all radial tire fitments, but they do not apply across the entire lineup in the same way because sub-model and wheel package determine which size belongs on a given vehicle.
The most important next step is confirming the exact sub-model and the actual wheel diameter on the Jeep before choosing a tire. Several trims can appear with more than one size, so selecting by model name alone can lead to the wrong 17-, 18-, 20-, or 21-inch application.
What size rim does a 2023 Jeep Trucks Grand Cherokee use?
A 2023 Jeep Trucks Grand Cherokee can use 17-inch, 18-inch, 20-inch, or 21-inch rims, depending on the sub-model and tire size. The matching tire sizes are 245/70R17 for 17-inch rims, 265/60R18 for 18-inch rims, 265/50R20 for 20-inch rims, and 275/45R21 for 21-inch rims.
That wide spread in wheel diameters means rim size should be checked before anything else. Looking at the current tire sidewall or measuring the wheel is often more reliable than assuming the wheel package is still original, especially if the vehicle has had wheels or tires changed.
Why does the 2023 Jeep Trucks Grand Cherokee have more than one tire size?
The 2023 Jeep Trucks Grand Cherokee has more than one tire size because the model range covers many sub-models with different wheel packages. Some trims use a single fitment, while others can appear with two sizes, including combinations such as 18- or 20-inch wheels or 20- or 21-inch wheels on higher trims.
That means tire selection starts with trim and wheel confirmation rather than broad model identification. A Laredo, Limited, or Summit 4xe may not use the same size as another Grand Cherokee parked beside it, so the safest approach is to verify both the sub-model and the wheel currently on the vehicle.
Choosing the Right Tire
What should I consider when choosing a tire for a 2023 Jeep Trucks Grand Cherokee?
Start with the correct size for the exact sub-model and wheel diameter, since the 2023 Jeep Trucks Grand Cherokee uses four different primary fitments. After that, compare tire construction, intended use, sidewall style where applicable, and product details such as rim-width compatibility, load capacity, and overall tire character.
A 17-inch Laredo application and a 21-inch Summit Reserve application are different buying situations even though both belong to the same model family. Matching the tire to the vehicle’s actual setup and how it is driven will be more useful than choosing by appearance or brand name alone.
What sidewall styles are available for 2023 Jeep Trucks Grand Cherokee tires?
Sidewall style depends on the tire size and product being considered. In the currently available 245/70R17 option for the 2023 Jeep Trucks Grand Cherokee, the BFGoodrich All-Terrain T/A KO2 uses an RWL sidewall, which is a raised white letter presentation rather than a plain blackwall look.
Sidewall treatment affects appearance more than fitment, but it can still matter to buyers who want the tire to suit the trim’s overall look. The key is to choose the correct tire size first, then decide whether the available sidewall style fits the vehicle’s visual direction and intended use.
What brands offer tires for the 2023 Jeep Trucks Grand Cherokee?
Current product coverage shown for the 2023 Jeep Trucks Grand Cherokee includes BFGoodrich in 245/70R17. That product is the All-Terrain T/A KO2 radial, a recognizable all-terrain series tied to one of the Grand Cherokee’s 17-inch fitments rather than the entire model range.
Brand comparison only helps after the correct size is confirmed, because one trim’s available tire choices may not carry over to another. A buyer with 18-, 20-, or 21-inch wheels should stay focused on that exact fitment first, then compare the brands and product types available within it.
Restoration & Appearance
Does correct tire fitment matter for a 2023 Jeep Trucks Grand Cherokee restoration or appearance-focused build?
Yes. Even on a modern vehicle like the 2023 Jeep Trucks Grand Cherokee, correct tire fitment shapes both the look and the stance of the vehicle. The model uses 17-, 18-, 20-, and 21-inch applications, so moving away from the proper size can change the visual balance as well as wheel-to-tire proportion.
Appearance-focused owners should begin by identifying the trim and wheel package they want to preserve, then match the tire size to that setup. That approach keeps the vehicle visually consistent without assuming that another Grand Cherokee size will deliver the same profile or presentation on the same vehicle.
Which tire should I choose for a period-style or trim-appropriate 2023 Jeep Trucks Grand Cherokee look?
A trim-appropriate look starts with the tire size that belongs on the exact 2023 Jeep Trucks Grand Cherokee sub-model and wheel package. On this model, that means staying with the correct 245/70R17, 265/60R18, 265/50R20, or 275/45R21 fitment before comparing the visual character of the available tire itself.
Once the right size is established, sidewall treatment and tread style help shape the final presentation. A raised white letter all-terrain look, for example, gives a different visual result than a more road-oriented tire, so appearance should be judged only after size and wheel diameter are confirmed.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2023 Jeep Trucks Grand Cherokee?
Yes. Wheel changes, suspension modifications, ride-height adjustments, or body alterations can all affect tire fitment on a 2023 Jeep Trucks Grand Cherokee. That matters even more on this model because the factory fitments already span 17-, 18-, 20-, and 21-inch wheel diameters across different trims.
A Grand Cherokee with aftermarket wheels should have its actual wheel diameter and width confirmed before replacement tires are selected. Clearance at the fenders and steering components also deserves attention, since a tire that suits one trim or wheel package may not suit another altered setup the same way.
What should I inspect before driving a 2023 Jeep Trucks Grand Cherokee on new tires?
Before road use, inspect the wheel size, tire pressure, lug torque, and overall tire condition on the 2023 Jeep Trucks Grand Cherokee. It also helps to confirm that all four tires match the intended fitment for the sub-model and that there is no rubbing at full steering lock or during suspension movement.
A short local test drive is a practical way to catch vibration, pulling, or clearance issues early. Since this model can use several different wheel and tire combinations, owners should also make sure the newly installed size matches the actual wheels on the vehicle rather than another trim’s specification.
How often should tires on a 2023 Jeep Trucks Grand Cherokee be inspected?
Tires on a 2023 Jeep Trucks Grand Cherokee should be inspected regularly for pressure loss, uneven tread wear, cuts, bulges, and sidewall damage. Routine checks matter on any vehicle, but they are especially useful here because different trims and wheel packages can place the tire in very different visual and load-bearing roles.
A quick inspection before longer trips and periodic checks between services can help catch problems early. Vehicles that sit for stretches, use larger wheel packages, or see rougher road conditions benefit from closer attention, since damage, low pressure, and wear patterns can develop before they are obvious from casual driving.
