The 2012 Jeep Trucks Grand Cherokee sits in the modern SUV era where one model line could span everyday highway use, upscale trim levels, and serious performance in the same showroom. That wide range matters when choosing tires, because this Grand Cherokee uses four different radial sizes depending on sub-model and wheel package. The fitment question starts with identifying whether the vehicle is a Laredo, Limited, Overland, Overland Summit, or SRT8, then confirming the wheel diameter already on the vehicle. From there, the decision becomes less about old bias-ply versus radial concerns and more about matching the correct metric size, sidewall style, and intended use to the vehicle's exact setup.
Which Tire Size Is Right for The 2012 Jeep Trucks Grand Cherokee
The 2012 Jeep Trucks Grand Cherokee uses four primary tire sizes, and the right one depends on the exact sub-model and wheel diameter. All of these fitments are metric radial sizes, but they span 17-inch, 18-inch, and 20-inch rims, so the first step is confirming both the trim level and the wheels currently on the vehicle. Once that is settled, the focus shifts to choosing the right tire style and use case within the correct size.
245/70R17 is a metric radial size in which 245 indicates section width in millimeters, 70 is the aspect ratio, R identifies radial construction, and 17 is the rim diameter in inches. On the 2012 Jeep Trucks Grand Cherokee, this size is tied to a 17-inch wheel setup and delivers a more traditional SUV fitment profile. Available choices in this size can differ by load specification, rim-width range, and sidewall treatment, including raised white letter styling. It is the size to evaluate when matching a Grand Cherokee configured around the 17-inch wheel package rather than the larger 18-inch or 20-inch combinations.
265/50R20 is a metric radial size with a 265-millimeter nominal section width, a 50-series profile, and a 20-inch rim diameter. This size gives the 2012 Jeep Trucks Grand Cherokee a lower-profile look than the 17-inch and 18-inch fitments while keeping the vehicle on a larger wheel. It is relevant to Grand Cherokee configurations that use 20-inch wheels, especially where appearance and on-road presentation are part of the package. Before selecting a tire in this size, confirm that the vehicle is using the correct 20-inch wheel setup and has not been changed to a different diameter since new.
265/60R18 uses the same 265-millimeter nominal width as 265/50R20, but the 60-series profile pairs it with an 18-inch rim instead of a 20-inch wheel. For the 2012 Jeep Trucks Grand Cherokee, this size belongs to sub-models equipped with the 18-inch wheel package and represents a different wheel-and-tire combination even though overall diameter stays in a similar range. The practical difference for a buyer is that wheel diameter is decisive here. A Grand Cherokee wearing 18-inch wheels needs a tire built for that rim, so this size should be matched to the actual wheel on the vehicle rather than chosen by appearance alone.
295/45R20 is a wide metric radial size that combines a 295-millimeter nominal section width with a 45-series profile on a 20-inch rim. On the 2012 Jeep Trucks Grand Cherokee, this size is associated with the SRT8 and stands apart from the narrower fitments used on other Grand Cherokee sub-models. The broader section width gives it a distinct role within the lineup, so it should not be treated as just another 20-inch option. Choosing this size starts with confirming that the vehicle is actually an SRT8 or retains the correct wheel setup intended for that fitment.
Tire fitment on the 2012 Jeep Trucks Grand Cherokee varies by sub-model, and some trims use more than one wheel-and-tire combination. Checking the exact trim matters here because the Laredo, Limited, Overland-family models, and SRT8 do not all share the same size.

2012 Jeep Trucks Grand Cherokee Laredo
The 2012 Jeep Trucks Grand Cherokee Laredo uses the 245/70R17 radial size. That keeps tire selection focused on matching the 17-inch wheel setup and then comparing available specifications such as sidewall style, load rating, and intended road or light-trail use.
The 2012 Jeep Trucks Grand Cherokee Limited can use either 265/60R18 or 265/50R20 radial tires, depending on wheel package. The key step is confirming whether the vehicle is on 18-inch or 20-inch wheels before comparing tire choices within the correct metric size.
The 2012 Jeep Trucks Grand Cherokee Overland also uses either 265/60R18 or 265/50R20 radials, tied to the wheel diameter on the vehicle. That means tire selection starts with wheel confirmation, then moves to choosing the right style and specification for the Grand Cherokee's current setup.
The 2012 Jeep Trucks Grand Cherokee Overland Summit shares the same two-size fitment pattern as other upper trims, using 265/60R18 or 265/50R20 radial tires. A buyer should verify the installed wheel diameter first, since the correct tire depends on the actual 18-inch or 20-inch wheel package.
The 2012 Jeep Trucks Grand Cherokee SRT8 uses the 295/45R20 radial size. That makes tire choice more specialized than on the other trims, with the main priority being confirmation that the vehicle still carries the proper 20-inch wheel setup for this wider fitment.
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 2012 Jeep Trucks Grand Cherokee?
The 2012 Jeep Trucks Grand Cherokee uses four primary radial tire sizes: 245/70R17, 265/60R18, 265/50R20, and 295/45R20. The correct size depends on the sub-model and wheel package. Laredo uses 245/70R17, SRT8 uses 295/45R20, and Limited, Overland, and Overland Summit use either 265/60R18 or 265/50R20.
That means the first step is not guessing by model name alone but confirming the exact trim and the wheels currently on the vehicle. Many Grand Cherokees have had wheel changes over time, so checking the tire sidewall and measuring wheel diameter helps prevent ordering an 18-inch tire for a 20-inch wheel or vice versa.
What size rim does a 2012 Jeep Trucks Grand Cherokee use?
A 2012 Jeep Trucks Grand Cherokee can use 17-inch, 18-inch, or 20-inch rims depending on the sub-model and tire size. The 245/70R17 fitment uses a 17-inch rim, 265/60R18 uses an 18-inch rim, and both 265/50R20 and 295/45R20 are built for 20-inch rims.
Rim diameter is the most important fitment checkpoint because tire and wheel diameters must match exactly. A Grand Cherokee with 20-inch wheels cannot use an 18-inch or 17-inch tire, even if the overall tire height looks close. It is also smart to confirm wheel width before comparing specific tire options within the correct diameter.
Do all 2012 Jeep Trucks Grand Cherokee sub-models use the same tire size?
No, the 2012 Jeep Trucks Grand Cherokee does not use one tire size across every sub-model. Laredo uses 245/70R17, SRT8 uses 295/45R20, and the Limited, Overland, and Overland Summit use either 265/60R18 or 265/50R20 depending on wheel package.
That variation matters because the Grand Cherokee lineup covered several different wheel-and-tire combinations in the same model year. A buyer should confirm both the trim badge and the actual wheel diameter on the vehicle before selecting a tire. That is especially important on used SUVs that may no longer wear their original wheels.
Choosing the Right Tire
What should I consider when choosing a tire for a 2012 Jeep Trucks Grand Cherokee?
Start with the correct tire size for the exact 2012 Jeep Trucks Grand Cherokee sub-model and wheel diameter. After that, compare construction, load specification, rim-width compatibility, sidewall style, and the kind of driving the vehicle actually sees. A Laredo on 245/70R17 tires has a different selection path than an SRT8 on 295/45R20.
The best comparison points are the tire's intended use and how closely it matches the vehicle's current setup. A highway-oriented Grand Cherokee, a lightly used family SUV, and one that sees rougher surfaces may call for different tread and sidewall priorities. Wheel width and clearance should be confirmed before moving outside the original size.
What sidewall styles are available for 2012 Jeep Trucks Grand Cherokee tires?
Sidewall style can vary by the specific tire offered in the correct size, and one available 245/70R17 option for the 2012 Jeep Trucks Grand Cherokee uses RWL, or raised white letter, sidewalls. That gives the tire a more traditional truck-and-SUV presentation than a plain black sidewall.
Sidewall appearance does not change the basic size requirement, but it can shape how the vehicle looks once mounted. Buyers who want a more utility-oriented visual style may prefer raised white letters, while others may want a cleaner appearance if a blackwall option exists in the needed size. Appearance should always come after confirming correct fitment.
What brands offer tires for the 2012 Jeep Trucks Grand Cherokee?
BFGoodrich is represented among the available tire options for the 2012 Jeep Trucks Grand Cherokee, including a 245/70R17 all-terrain radial application. Brand matters as part of the buying decision, but only after the correct size, wheel diameter, and intended use have been narrowed down.
A useful way to compare brands is to look at what each tire is trying to do rather than relying on name alone. For a Grand Cherokee, that may include all-terrain design, sidewall styling, rim-width compatibility, and load capacity. Matching the tire's character to the SUV's actual use usually matters more than brand recognition by itself.
Restoration & Appearance
Which tire should I choose for a period-style 2012 Jeep Trucks Grand Cherokee?
A period-style choice for a 2012 Jeep Trucks Grand Cherokee starts with keeping the correct original-type metric radial size for the exact sub-model and wheel diameter. The right visual starting point is 245/70R17, 265/60R18, 265/50R20, or 295/45R20, depending on how the vehicle was equipped.
Appearance comes from the full combination of tire size, wheel diameter, and sidewall presentation rather than from size alone. A raised white letter tire can give a more traditional SUV look on some setups, while a lower-profile 20-inch fitment changes the visual stance entirely. Buyers chasing strict originality should compare against vehicle-specific factory references.
Does correct tire fitment matter for a 2012 Jeep Trucks Grand Cherokee restoration?
Yes, correct tire fitment matters on a 2012 Jeep Trucks Grand Cherokee restoration because the model year used several different wheel-and-tire combinations across the lineup. Getting the proper size family back on the vehicle helps preserve its intended stance, proportions, and trim-specific presentation.
That does not just mean choosing any tire that fits the wheel. It means confirming whether the vehicle should be on a 17-inch, 18-inch, or 20-inch setup and then selecting the matching metric radial size. On a restored or carefully preserved Grand Cherokee, those details affect both appearance and how authentic the finished vehicle feels.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2012 Jeep Trucks Grand Cherokee?
Yes, modifications can affect tire fitment on a 2012 Jeep Trucks Grand Cherokee even when the tire size matches one of the original applications. Wheel changes, altered offsets, suspension lifts or lowering, and body modifications can all change how much room the tire has during steering and suspension travel.
That matters most on trims that use 20-inch wheels or wider sizes such as 295/45R20, where clearance can become tighter if the setup has been changed. Checking wheel width, offset, inner clearance, and fender space is a smart step before mounting replacement tires. A quick visual check is not enough on a modified vehicle.
What should I inspect before driving a 2012 Jeep Trucks Grand Cherokee on new tires?
Before driving a 2012 Jeep Trucks Grand Cherokee on new tires, inspect the wheel diameter and width, verify that the mounted size matches the sub-model, and confirm proper inflation. It is also wise to look over the wheels for damage and make sure the tires have adequate clearance at full steering lock.
A short road test should include attention to vibration, rubbing, and air pressure stability after the first miles. On an SUV that has seen wheel swaps or suspension work, rechecking clearance under load can prevent surprises later. Routine inspection afterward should include tread wear, cuts, bulges, cracking, and any sign of slow air loss.
How often should tires on a 2012 Jeep Trucks Grand Cherokee be inspected?
Tires on a 2012 Jeep Trucks Grand Cherokee should be inspected regularly, with a quick visual check before normal driving and a more careful inspection before longer trips. The main points to watch are inflation, uneven wear, cracking, punctures, bulges, and any evidence that the tire is contacting suspension or body parts.
Inspection becomes even more important if the Grand Cherokee is driven infrequently or spends long periods parked. Tires can age and lose pressure without accumulating many miles, and that matters on both everyday SUVs and collector-kept examples. Consistent pressure checks and periodic professional inspection help catch problems before they turn into road-use issues.
