The 2015 Jeep Trucks Grand Cherokee sits in the modern SUV era where daily comfort, highway manners, and genuine utility all matter, but trim level changes can alter the tire fitment significantly. That matters on this vehicle because the Grand Cherokee uses four primary radial sizes across 17-, 18-, and 20-inch wheel packages. The main decision is not simply choosing a tire brand, but confirming the exact sub-model and wheel diameter first. Once that is settled, the fitment path becomes much clearer, especially since the available product selection shown here centers on a 245/70R17 all-terrain option. Owners should match the tire to the Jeep's actual wheel setup and intended road use before replacing anything.
Which Tire Size Is Right for The 2015 Jeep Trucks Grand Cherokee
Four primary tire sizes apply to the 2015 Jeep Trucks Grand Cherokee, and they vary by sub-model and wheel package rather than by construction, since all of them are radial tires. The first step is confirming the exact trim and wheel diameter on the vehicle, because this Grand Cherokee can use 17-, 18-, or 20-inch rims depending on configuration.
245/70R17 is a metric radial size in which 245 is the nominal section width in millimeters, 70 is the aspect ratio, R identifies radial construction, and 17 is the rim diameter in inches. On the 2015 Jeep Trucks Grand Cherokee, this size is tied to a 17-inch wheel setup and suits trims that use the smaller-diameter package. Available product choice here includes a BFGoodrich All-Terrain T/A KO2 with raised white letter styling and an all-terrain character. This size is worth evaluating carefully when preserving the Jeep's original wheel diameter and sidewall height is part of the goal.
265/60R18 is a metric radial size that uses a 265-millimeter nominal section width, a 60-series aspect ratio, and an 18-inch rim diameter. This is one of the most broadly used sizes on the 2015 Jeep Trucks Grand Cherokee, appearing across several sub-models that share an 18-inch wheel package. Its role in the lineup makes it especially important to confirm whether the vehicle still has its original wheels or has been changed to a different factory-size package. Buyers comparing this size should focus on matching the actual trim and wheel setup before moving on to tread pattern or brand preference.
265/50R20 is a metric radial with a 265-millimeter nominal section width, a lower 50-series aspect ratio, and a 20-inch rim diameter. On the 2015 Jeep Trucks Grand Cherokee, this size belongs to specific higher-trim wheel packages rather than the entire model range. The lower-profile format gives it a different fitment character than the 17- and 18-inch options, so wheel diameter confirmation is essential before selection. This size makes the most sense for owners keeping the Jeep on its existing 20-inch setup and wanting to stay aligned with that package's original tire dimensions.
295/45R20 is a metric radial size with a substantially wider 295-millimeter nominal section width, a 45-series aspect ratio, and a 20-inch rim diameter. Within the 2015 Jeep Trucks Grand Cherokee range, this size is specific to the SRT and should not be treated as a universal 20-inch fitment for every Grand Cherokee. Its extra width makes exact wheel and clearance confirmation especially important if the vehicle has seen any wheel, suspension, or alignment changes. Owners selecting this size should approach it as an SRT-specific fitment rather than simply a larger alternative to the other Grand Cherokee sizes.
Tire fitment on the 2015 Jeep Trucks Grand Cherokee depends heavily on the exact sub-model, and several trims use more than one factory size. Checking the trim and the wheel diameter already on the vehicle is the quickest way to narrow the correct tire choice.

2015 Jeep Trucks Grand Cherokee Laredo
The 2015 Jeep Trucks Grand Cherokee Laredo uses either a 245/70R17 radial or a 265/60R18 radial, depending on its wheel package. That means tire selection starts with confirming whether the Jeep is on 17-inch or 18-inch wheels before comparing tread style or intended use.
The 2015 Jeep Trucks Grand Cherokee Limited can use either 265/60R18 or 265/50R20 radial tires. Choosing correctly comes down to verifying whether the vehicle carries the 18-inch or 20-inch wheel setup, especially if the wheels may have been changed over time.
The 2015 Jeep Trucks Grand Cherokee Overland uses either 265/60R18 or 265/50R20 radial tires. Owners should confirm the installed wheel diameter first, since both sizes belong to this trim but are not interchangeable without checking the Jeep's actual wheel package.
The 2015 Jeep Trucks Grand Cherokee SRT uses a 295/45R20 radial tire, setting it apart from the other Grand Cherokee trims covered here. That wider 20-inch fitment makes exact wheel match and clearance verification especially important before replacement.
The 2015 Jeep Trucks Grand Cherokee Summit uses either 265/60R18 or 265/50R20 radial tires. Tire choice depends on the wheel package currently on the vehicle, so confirming the existing 18-inch or 20-inch rim is the key first step.
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.

Tire Size & Fitment
What tire size fits a 2015 Jeep Trucks Grand Cherokee?
The 2015 Jeep Trucks Grand Cherokee uses four primary tire sizes across its range: 245/70R17, 265/60R18, 265/50R20, and 295/45R20. All of these are radial sizes, but they do not apply to every Grand Cherokee trim in the same way.
The right choice depends first on the exact sub-model and wheel diameter already on the vehicle. A Laredo can use either a 17-inch or 18-inch package, several trims use either 18-inch or 20-inch tires, and the SRT uses 295/45R20, so checking the tire sidewall and wheel before replacement is essential.
What size rim does a 2015 Jeep Trucks Grand Cherokee use?
The 2015 Jeep Trucks Grand Cherokee uses 17-inch, 18-inch, or 20-inch rims depending on the trim and tire package. Those rim diameters correspond to the primary tire sizes 245/70R17, 265/60R18, 265/50R20, and 295/45R20.
Wheel diameter is the most important fitment checkpoint on this model because several trims were offered with more than one package. Looking only at the model name is not enough; the actual wheel on the Jeep needs to match the tire's rim diameter, and any aftermarket wheel change should be confirmed before choosing a replacement tire.
Do all 2015 Jeep Trucks Grand Cherokee sub-models use the same tire size?
No, the 2015 Jeep Trucks Grand Cherokee does not use one tire size across every sub-model. Laredo uses 245/70R17 or 265/60R18, Limited, Overland, and Summit use 265/60R18 or 265/50R20, and SRT uses 295/45R20.
That variation means trim level matters, but wheel package matters just as much. Two Grand Cherokees with the same model year may need different tires because one has 18-inch wheels and another has 20-inch wheels, so the safest approach is to confirm both the sub-model and the tire size currently mounted before ordering replacements.
Choosing the Right Tire
What should I consider when choosing a 245/70R17 tire for a 2015 Jeep Trucks Grand Cherokee?
Start with the basics: the tire must match the Jeep's 245/70R17 size and 17-inch rim. From there, the choice becomes more about use and construction details, such as whether an all-terrain tread suits the vehicle's driving pattern better than a more road-focused replacement.
The available 245/70R17 option shown here is a BFGoodrich All-Terrain T/A KO2 with radial construction, raised white letters, a 6.5 to 8.0 inch rim-width range, and a maximum load capacity of 3,000 lbs @ 80 psi. Those details matter when balancing appearance, wheel compatibility, and how the Grand Cherokee will actually be driven.
What sidewall styles are available for 2015 Jeep Trucks Grand Cherokee tires?
The available product selection shown here includes an RWL sidewall, which means raised white letters. That appearance gives a more aggressive and visibly branded sidewall presentation than a plain blackwall, and it pairs naturally with an all-terrain tire style.
Sidewall style is mostly an appearance decision unless a specific tire line only comes in one treatment. On a 2015 Jeep Trucks Grand Cherokee, the important step is still matching the correct tire size and wheel diameter first, then deciding whether a more traditional black sidewall or an RWL presentation better suits the Jeep's look.
What brands offer tires for the 2015 Jeep Trucks Grand Cherokee?
The product selection shown here includes BFGoodrich for the 245/70R17 fitment. That available option is part of the All-Terrain T/A KO2 line, which gives this particular size a clear all-terrain product path rather than a broad multi-brand comparison on this page.
Brand alone should not drive the choice on a 2015 Jeep Trucks Grand Cherokee. The better approach is to confirm the exact size first, then compare the available tire's intended use, sidewall style, rim-width compatibility, and load-oriented specification so the replacement still matches the Jeep's wheel setup and use case.
Restoration & Appearance
Which tire should I choose for a period-style 2015 Jeep Trucks Grand Cherokee?
A period-style choice for a 2015 Jeep Trucks Grand Cherokee starts with keeping the correct size and wheel diameter for the trim rather than chasing a vintage look. Since this is a modern SUV with radial fitments throughout, the most authentic presentation usually comes from staying with the proper factory-era size format and overall stance.
Appearance decisions still matter, especially if the Jeep is being kept close to its original character. Matching the existing 17-, 18-, or 20-inch wheel package is the first step, and then sidewall treatment and tread style can refine the look without moving away from the tire dimensions that belong on that particular trim.
Does correct tire fitment matter for a 2015 Jeep Trucks Grand Cherokee restoration?
Yes, correct tire fitment matters because the 2015 Jeep Trucks Grand Cherokee used multiple sizes across its trim range, and each one affects the vehicle's stance and visual balance. Using the wrong wheel diameter or a tire meant for another sub-model can change the Jeep's appearance in ways that are immediately noticeable.
A restoration-oriented approach should begin with confirming the exact sub-model and wheel package the vehicle is meant to carry. Once that is settled, the buyer can choose a tire that supports the intended appearance, whether that means preserving a stock-style presentation or selecting an all-terrain look that still respects the Jeep's correct size.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2015 Jeep Trucks Grand Cherokee?
Yes, modifications can affect tire fitment on a 2015 Jeep Trucks Grand Cherokee even when the replacement tire matches one of the vehicle's original sizes. Wheel changes, offset differences, suspension alterations, or body modifications can all change how much space the tire has at the fender, steering components, and suspension.
That matters most on this model because it already uses several different factory wheel diameters and widths across the lineup. A Grand Cherokee that has been lowered, lifted, or fitted with aftermarket wheels should have its actual wheel size and clearance checked before replacing tires, especially with wider fitments like the SRT's 295/45R20.
What should I inspect before driving a 2015 Jeep Trucks Grand Cherokee on new tires?
Before road use, inspect the wheel diameter and tire size match, verify inflation, and confirm that the tires clear the suspension and bodywork through the full steering range. It is also smart to look over the wheels themselves for damage, poor bead seating, or signs that the Jeep's alignment or suspension condition may need attention.
A short test drive followed by a second visual check can catch rubbing, vibration, or unusual wear patterns early. On a 2015 Jeep Trucks Grand Cherokee, that step is especially useful when replacing tires on a vehicle with multiple possible wheel packages, or when the Jeep may have had previous wheel or suspension changes.
How often should tires on a 2015 Jeep Trucks Grand Cherokee be inspected?
Tires on a 2015 Jeep Trucks Grand Cherokee should be inspected regularly, not just when tread looks low. Frequent visual checks for uneven wear, cuts, bulges, sidewall damage, and air loss are important, and a more thorough inspection makes sense before trips, seasonal use changes, or any time ride quality begins to feel different.
Low-use vehicles still need attention because age and storage conditions can affect tire condition even when mileage is limited. Pressure checks, tread review, and a look at the inner and outer sidewalls help catch problems early, and any Grand Cherokee with uncertain tire age or visible damage should be evaluated before extended road use.
