The 2020 Jeep Trucks Grand Cherokee sits at the point where Jeep’s long-running SUV formula blends everyday road comfort with serious trim-level variety, from straightforward Laredo models to the much more aggressive SRT and Trackhawk. That breadth matters when it is time to choose tires, because this Grand Cherokee uses four different primary radial sizes: 245/70R17, 265/60R18, 265/50R20, and 295/45R20. Some trims share a common road-oriented size, while others step into wider or different-wheel fitments. The key is matching the exact sub-model and wheel diameter first, then choosing a tire that suits the vehicle’s intended use, appearance, and current wheel setup.
Which Tire Size Is Right for The 2020 Jeep Trucks Grand Cherokee
The 2020 Jeep Trucks Grand Cherokee uses four primary tire sizes, and the right one depends on the exact sub-model and wheel diameter. These are all radial fitments, but they span 17-inch, 18-inch, and 20-inch rims, so the first step is confirming the specific trim and the wheels currently on the vehicle before comparing tread style or product options.
Fit(s): Altitude, High Altitude, High Altitude V8 4x4, Limited, Limited V8 4x4, Limited X, Limited X V8 4x4, Overland, Overland V8 4x4, Summit, Summit V8 4x4, and Upland
Construction: Radial|Rim: 20 in
A 265/50R20 tire is a metric radial size with a 265-millimeter section width, a 50-series aspect ratio, and fitment for a 20-inch rim. On the 2020 Jeep Trucks Grand Cherokee, this size appears on several higher-trim configurations, making it one of the core road-oriented fitments in the lineup. Its sizing format is familiar to modern buyers and centers the decision on matching the exact wheel diameter and trim application rather than decoding an older system. This is the size to evaluate when your Grand Cherokee is equipped with factory-style 20-inch wheels and a street-focused stance.
A 245/70R17 tire is a metric radial size that uses a 245-millimeter section width, a 70-series profile, and a 17-inch rim. On the 2020 Jeep Trucks Grand Cherokee, this size is tied to Laredo applications and gives the buyer a clear starting point when the vehicle retains its 17-inch wheel setup. BFGoodrich offers this size in the All-Terrain T/A KO2 series with raised white letter sidewalls, adding a more rugged visual character than a plain highway-style tire. It is the size to review when utility, wheel confirmation, and intended driving surface all matter more than simply matching overall diameter.
Fit(s): Laredo E, Limited, Limited V8 4x4, Overland, Overland V8 4x4, and Trailhawk
Construction: Radial|Rim: 18 in
A 265/60R18 tire uses a metric radial format with a 265-millimeter section width, a 60-series profile, and an 18-inch rim diameter. On the 2020 Jeep Trucks Grand Cherokee, this size appears across several trims, including applications where 18-inch wheels are part of the fitment decision instead of 20-inch wheels. The code itself points to a taller sidewall profile than the 265/50R20 alternative, so the buyer’s main task is confirming which wheel package is actually on the vehicle. This size is the right one to investigate when the Grand Cherokee carries factory-style 18-inch wheels or has trim-dependent fitment choices.
A 295/45R20 tire is a metric radial size with a 295-millimeter section width, a 45-series aspect ratio, and a 20-inch rim diameter. On the 2020 Jeep Trucks Grand Cherokee, this wider 20-inch fitment belongs to SRT and Trackhawk applications rather than the broader trim range that uses narrower sizes. The format is straightforward, but the practical importance lies in recognizing that it serves a specific performance-oriented branch of the model line. This is the size to verify when a Grand Cherokee has the correct SRT or Trackhawk wheel setup and should not be confused with other 20-inch Grand Cherokee fitments.
Tire fitment on the 2020 Jeep Trucks Grand Cherokee varies noticeably by sub-model, and several trims can use more than one primary size depending on wheel configuration. Checking the exact trim name and current rim diameter is the most important step before selecting a replacement tire.

2020 Jeep Trucks Grand Cherokee Altitude
The 2020 Jeep Trucks Grand Cherokee Altitude uses the 265/50R20 radial size. Tire selection here starts with confirming the 20-inch wheel setup, then choosing a replacement that matches the vehicle’s road-use focus and desired appearance.
The 2020 Jeep Trucks Grand Cherokee High Altitude uses the 265/50R20 radial fitment. That keeps the decision centered on 20-inch tire choice rather than multiple size possibilities, with attention to wheel condition and how the vehicle is driven.
2020 Jeep Trucks Grand Cherokee High Altitude V8 4x4
The 2020 Jeep Trucks Grand Cherokee High Altitude V8 4x4 also uses 265/50R20 radial tires. The main consideration is staying with the correct 20-inch size while checking that the current wheel package has not been changed from its intended setup.
The 2020 Jeep Trucks Grand Cherokee Laredo uses the 245/70R17 radial size. That makes wheel diameter especially easy to confirm, and it also gives buyers a straightforward path if they want a more utility-oriented tire in the proper 17-inch fitment.
The 2020 Jeep Trucks Grand Cherokee Laredo E can use either 245/70R17 or 265/60R18 radial tires, depending on wheel setup. Tire selection starts with verifying whether the vehicle is on 17-inch or 18-inch rims before comparing any product characteristics.
The 2020 Jeep Trucks Grand Cherokee Limited can be fitted with either 265/50R20 or 265/60R18 radial tires. The important step is confirming which wheel diameter is on the vehicle, since both sizes belong to this trim but are not interchangeable without that check.
The 2020 Jeep Trucks Grand Cherokee Limited V8 4x4 shares the same two-size situation: 265/50R20 or 265/60R18. That means the trim name alone is not enough, and the buyer should confirm the actual wheel diameter before moving on to replacement choices.
The 2020 Jeep Trucks Grand Cherokee Limited X uses 265/50R20 radial tires. With only one primary size tied to this trim, the focus shifts from fitment uncertainty to choosing the right 20-inch tire for the vehicle’s use and wheel setup.
The 2020 Jeep Trucks Grand Cherokee Limited X V8 4x4 also uses the 265/50R20 radial fitment. Tire shopping is more straightforward here, but it still pays to confirm the current wheels if the vehicle has seen any aftermarket changes.

The 2020 Jeep Trucks Grand Cherokee Overland V8 4x4 shares the same dual-size fitment of 265/50R20 or 265/60R18. Buyers should verify the installed wheel package first, since the correct replacement tire depends on that hardware rather than trim name alone.
The 2020 Jeep Trucks Grand Cherokee SRT uses the wider 295/45R20 radial size. This trim calls for careful attention to the correct 20-inch wheel setup and should be matched to a tire intended for that specific performance-oriented fitment.

Fitment questions for the 2020 Jeep Trucks Grand Cherokee usually come down to exact trim, wheel diameter, and the difference between its four primary radial sizes. The FAQs below focus on size identification, product selection, and the wheel, maintenance, and road-use checks that matter before replacement.
Tire Size & Fitment
What tire size fits a 2020 Jeep Trucks Grand Cherokee?
The 2020 Jeep Trucks Grand Cherokee uses four primary tire sizes: 245/70R17, 265/60R18, 265/50R20, and 295/45R20. All of them are radial fitments, but they do not apply across every trim, so the correct size depends on the exact sub-model and wheel package on the vehicle.
The practical next step is to confirm both the trim and the actual rim diameter before ordering tires. Several Grand Cherokee versions share similar names yet use different wheels, and some trims can be found with more than one primary size, so checking the door placard and the current tire sidewall helps prevent a mismatch.
What size rim does a 2020 Jeep Trucks Grand Cherokee use?
A 2020 Jeep Trucks Grand Cherokee can use 17-inch, 18-inch, or 20-inch rims, depending on the sub-model. The 245/70R17 size fits a 17-inch rim, 265/60R18 fits an 18-inch rim, and both 265/50R20 and 295/45R20 are built for 20-inch rims.
That makes rim diameter the first thing to verify before comparing any replacement tires. A Grand Cherokee with 20-inch wheels still needs the correct 20-inch tire size for its specific trim, and a change in wheel package from a previous owner can alter what the vehicle currently requires.
Why does the 2020 Jeep Trucks Grand Cherokee have more than one tire size?
The 2020 Jeep Trucks Grand Cherokee spans a wide range of trims, so tire size changes with wheel diameter and vehicle configuration. Laredo models use the smaller 245/70R17 fitment, Trailhawk uses 265/60R18, many upper trims use 265/50R20, and SRT and Trackhawk use the wider 295/45R20 size.
That means the model name alone is not enough for safe tire selection. Checking the exact sub-model, the installed wheel diameter, and the current tire size on the vehicle helps separate a routine replacement from a fitment mistake, especially on trims that can use either 18-inch or 20-inch wheels.
Choosing the Right Tire
What should I consider when choosing a tire for a 2020 Jeep Trucks Grand Cherokee?
Start with the correct primary size for the exact 2020 Jeep Trucks Grand Cherokee sub-model, then confirm the wheel diameter already on the vehicle. From there, compare the tire’s intended use, construction type, and whether the fitment is aimed more at everyday road driving, all-terrain use, or a wider performance-oriented setup.
The most useful final checks are rim-width compatibility, load capacity, and how the vehicle is actually used. A Grand Cherokee that stays on pavement may call for a different type of tire than one that sees rougher surfaces, and any previous wheel change should be verified before narrowing the choices.
What sidewall styles are available for 2020 Jeep Trucks Grand Cherokee tires?
Among the available products here, the visible sidewall style is RWL, or raised white letter, on the BFGoodrich All-Terrain T/A KO2 in 245/70R17. That gives the tire a more pronounced off-road-inspired appearance than a plain black sidewall treatment.
Sidewall style matters mostly when appearance is part of the decision, but it should still come after confirming the correct tire size and wheel diameter. A raised white letter look can suit a more rugged Grand Cherokee presentation, especially on Laredo-based 17-inch applications, without changing the need for proper fitment.
What brands offer tires for the 2020 Jeep Trucks Grand Cherokee?
BFGoodrich is represented in the available product selection for the 2020 Jeep Trucks Grand Cherokee, specifically in the 245/70R17 size. That product is the All-Terrain T/A KO2, a radial tire that combines the correct 17-inch fitment with an all-terrain character and raised white letter sidewalls.
Brand is only one part of the choice, so it helps to compare it alongside size, wheel compatibility, and the vehicle’s intended use. On a Grand Cherokee, the right tire still begins with the proper trim-specific fitment, especially since this model uses multiple wheel diameters across its lineup.
Restoration & Appearance
Which tire should I choose for a period-style 2020 Jeep Trucks Grand Cherokee?
A 2020 Jeep Trucks Grand Cherokee is too recent for restoration in the vintage sense, but appearance still matters when keeping the vehicle close to its original trim character. The most appropriate starting point is the correct factory-size-type fitment for the exact sub-model, whether that means 17-inch, 18-inch, or 20-inch radial tires.
Staying with the proper size preserves the wheel-and-tire proportions intended for that trim, while sidewall and tread style shape the final look. Buyers aiming for a clean, trim-appropriate presentation should confirm the existing wheel package first, then avoid moving to a different size simply for appearance alone.
Does correct tire fitment matter for a 2020 Jeep Trucks Grand Cherokee restoration or preservation-minded build?
Correct tire fitment matters because the 2020 Jeep Trucks Grand Cherokee uses several different sizes across its trim range, and each one relates to a particular wheel diameter and overall presentation. Using the proper size helps preserve how the vehicle sits, fills the wheel opening, and functions with its intended setup.
Preservation-minded owners should verify the exact sub-model and current wheels before replacing tires, especially on trims that can use more than one size. That approach keeps the vehicle closer to its intended configuration and avoids introducing unnecessary fitment questions through an avoidable wheel-and-tire mismatch.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Jeep Trucks Grand Cherokee?
Yes. Modifications can change tire fitment on a 2020 Jeep Trucks Grand Cherokee even when the size looks close to stock. Aftermarket wheels, altered offsets, suspension lifts or lowering, and body changes can all affect clearance, steering travel, and whether the original trim-based tire size still makes sense on the vehicle.
The safest approach is to confirm the current wheel diameter and width, then inspect for clearance at full steering lock and under suspension movement. A Grand Cherokee that has been modified should be evaluated as it sits now, not only by its trim name, before any replacement tire is selected.
What should I inspect before driving a 2020 Jeep Trucks Grand Cherokee on new tires?
Before driving a 2020 Jeep Trucks Grand Cherokee on new tires, inspect the wheel condition, lug hardware, inflation pressure, and overall tire seating on the rim. It also helps to make sure the chosen size matches the vehicle’s exact wheel diameter and that there is no visible interference at the fender or suspension.
A short, careful road test is a good way to confirm there is no rubbing, vibration, or unusual pull after installation. Rechecking pressure after the first drive and looking over the tires again can catch a simple setup issue early, especially on trims that use wider 20-inch fitments.
How often should tires on a 2020 Jeep Trucks Grand Cherokee be inspected?
Tires on a 2020 Jeep Trucks Grand Cherokee should be inspected regularly, not only at replacement time. A visual check for uneven wear, sidewall damage, cuts, bulges, low pressure, or embedded debris helps catch problems before they become more serious, especially on a heavier SUV that may see mixed road conditions.
Monthly checks are a sensible habit, along with another inspection before longer trips or seasonal driving changes. It also helps to pay attention after curb impacts or potholes, since wheel damage or alignment changes can affect how a Grand Cherokee’s tires wear even when the size itself is correct.
