The 2006 Jeep Trucks Grand Cherokee sits at an interesting point in the model’s evolution, blending traditional SUV utility with a more refined, road-focused feel, and in SRT8 form, adding serious performance intent. Tire fitment reflects that split personality. Standard Grand Cherokee sub-models use 17-inch radial sizes such as 235/65R17 and 245/65R17, while the SRT8 uses a staggered 20-inch setup with 255/45R20 front and 285/40R20 rear tires. That means the real decision starts with identifying the exact sub-model and wheel package, then narrowing the choice by tire type, sidewall style, and how the vehicle is used on the road.
Which Tire Size Is Right for The 2006 Jeep Trucks Grand Cherokee
The 2006 Jeep Trucks Grand Cherokee uses four primary tire sizes, and the right one depends on the exact sub-model and wheel diameter. Most versions use 17-inch radial tires in either 235/65R17 or 245/65R17, while the SRT8 uses a staggered 20-inch radial setup with different front and rear sizes. Confirming the sub-model and whether the vehicle has 17-inch or 20-inch wheels is the first step before comparing available tire choices.
Fit(s): 65th Anniversary Edition, Laredo, Limited, and Overland
Construction: Radial|Rim: 17 in
In 235/65R17, 235 is the section width in millimeters, 65 is the aspect ratio, R identifies radial construction, and 17 is the wheel diameter in inches. This is a modern metric radial size used on several 2006 Jeep Trucks Grand Cherokee sub-models with 17-inch wheels, giving it a straightforward fitment profile for standard non-SRT8 applications. Buyers comparing this size should focus on confirming the exact wheel setup and overall vehicle configuration first. That matters most on Grand Cherokees that may have seen wheel changes or trim swaps over time.
Fit(s): 65th Anniversary Edition, Laredo, Limited, and Overland
Construction: Radial|Rim: 17 in
The 245/65R17 size follows the same metric radial format, with a 245-millimeter section width, a 65-series profile, radial construction, and a 17-inch rim diameter. On the 2006 Jeep Trucks Grand Cherokee, this size appears across several mainstream sub-models and adds another 17-inch fitment that must be matched to the vehicle’s actual wheel package. Available product choice in this size includes BFGoodrich with a raised white letter sidewall in the All Terrain TA KO2 series. It is a useful size to evaluate when the vehicle is expected to balance road use with a more truck-oriented tire appearance.
A 255/45R20 tire uses a 255-millimeter section width, a 45-series profile, radial construction, and a 20-inch wheel diameter. On the 2006 Jeep Trucks Grand Cherokee, this size serves the SRT8 front position, so it is part of a performance-oriented staggered setup rather than a universal fitment across the model line. Product selection is broader here, with BFGoodrich, Nitto, and Pro-Trac choices plus Blackwall, RWL, and Redline sidewall treatments across several tire series. This size calls for careful attention to front-position use, wheel width, and maintaining the intended staggered relationship with the rear tire.
In 285/40R20, the 285 designates section width in millimeters, 40 is the aspect ratio, R means radial, and 20 is the required wheel diameter in inches. This size is used on the rear of the 2006 Jeep Trucks Grand Cherokee SRT8, making it specific to the back of that staggered setup. Its role is different from the 17-inch fitments and also different from the SRT8 front tire, so it should be treated as a position-specific size rather than a general Grand Cherokee replacement. Rear tire selection should stay tied to the actual wheel dimensions and overall front-to-rear setup already on the vehicle.
Sub-model fitment matters on the 2006 Jeep Trucks Grand Cherokee because tire sizing is not the same across the lineup. Most standard versions share 17-inch radial fitments, while the SRT8 uses a staggered 20-inch front-and-rear combination that should be confirmed before selecting tires.

2006 Jeep Trucks Grand Cherokee 65th Anniversary Edition
The 2006 Jeep Trucks Grand Cherokee 65th Anniversary Edition uses 17-inch radial tire sizing and shares its fitment pattern with several other standard Grand Cherokee trims. Tire selection here comes down to confirming which of the two 17-inch sizes is on the vehicle now and whether the goal is everyday road use or a more truck-oriented look.
The 2006 Jeep Trucks Grand Cherokee Laredo uses one of the 17-inch radial tire sizes found on the standard Grand Cherokee range. The key step is matching the tire to the actual wheel package on the vehicle, especially if it has changed hands over the years or has been fitted with different wheels.
The 2006 Jeep Trucks Grand Cherokee Limited stays within the 17-inch radial fitment group rather than the SRT8’s larger staggered setup. That keeps tire selection relatively straightforward once the installed wheel and exact size are confirmed, after which choices can focus on tread character and sidewall presentation.
The 2006 Jeep Trucks Grand Cherokee Overland also uses 17-inch radial sizing within the standard Grand Cherokee family. Buyers should verify which of the two 17-inch sizes is actually mounted, then compare tire options with attention to wheel width, intended driving use, and the vehicle’s present setup.
The 2006 Jeep Trucks Grand Cherokee SRT8 Front uses 255/45R20, making it distinct from the 17-inch fitments used elsewhere in the lineup. Tire choice here should preserve the front position’s role in the staggered SRT8 setup and take into account the available performance-oriented series and sidewall treatments.
The 2006 Jeep Trucks Grand Cherokee SRT8 Rear uses 285/40R20 as the rear half of the model’s staggered radial arrangement. That makes rear tire selection a matter of maintaining the correct back-wheel sizing relationship rather than treating it like a single-size replacement shared with the rest of the Grand Cherokee range.
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.

The most common questions for the 2006 Jeep Trucks Grand Cherokee come down to identifying the right size by sub-model, understanding the 17-inch versus 20-inch fitments, and comparing available tire styles for standard models and SRT8 applications.
Tire Size & Fitment
What tire size fits a 2006 Jeep Trucks Grand Cherokee?
The 2006 Jeep Trucks Grand Cherokee uses four primary tire sizes: 235/65R17, 245/65R17, 255/45R20, and 285/40R20. The 17-inch sizes apply to standard Grand Cherokee sub-models, while the SRT8 uses a staggered 20-inch setup with 255/45R20 in front and 285/40R20 in the rear.
That means the correct tire is tied to the exact trim and wheel package rather than the model name alone. Checking the sub-model, wheel diameter, and whether the vehicle has matching or staggered front-and-rear sizes will prevent confusion, especially on Grand Cherokees that may have received aftermarket wheels or replacement rims over time.
What size rim does a 2006 Jeep Trucks Grand Cherokee use?
A 2006 Jeep Trucks Grand Cherokee uses either 17-inch or 20-inch rims, depending on the sub-model and tire size. The 235/65R17 and 245/65R17 sizes mount on 17-inch wheels, while the SRT8’s 255/45R20 front and 285/40R20 rear sizes use 20-inch wheels.
Rim diameter should be confirmed before anything else because a 17-inch tire cannot be mounted on a 20-inch wheel, and vice versa. It is also smart to verify the actual wheel setup on the vehicle rather than assuming it still matches its original trim, since wheel swaps are common on used SUVs and performance models.
Do all 2006 Jeep Trucks Grand Cherokee sub-models use the same tire size?
No, the 2006 Jeep Trucks Grand Cherokee does not use one tire size across every sub-model. The 65th Anniversary Edition, Laredo, Limited, and Overland use 17-inch radial sizing in either 235/65R17 or 245/65R17, while the SRT8 uses 255/45R20 front and 285/40R20 rear.
That split makes sub-model identification especially important before choosing tires. Standard Grand Cherokee trims stay within a conventional 17-inch fitment family, but the SRT8 requires attention to both axle position and wheel diameter, so a quick check of the existing tire sidewall and wheel size can save a costly mismatch.
Choosing the Right Tire
What should I consider when choosing a tire for a 2006 Jeep Trucks Grand Cherokee?
Start with the exact tire size already tied to the vehicle’s sub-model and wheel diameter. A standard 17-inch Grand Cherokee and an SRT8 do not use the same fitment, and the SRT8 also requires attention to front-versus-rear sizing because its setup is staggered.
Once the size is confirmed, compare the tire’s intended character, sidewall presentation, and wheel-width compatibility where that detail is available. A buyer choosing 245/65R17 may lean toward a more truck-oriented all-terrain presentation, while a 255/45R20 SRT8 owner may be focused more on road use, appearance, and keeping the front setup consistent with the rear.
What sidewall styles are available for 2006 Jeep Trucks Grand Cherokee tires?
Available sidewall styles for 2006 Jeep Trucks Grand Cherokee tires include Blackwall, RWL, and Redline, depending on the size. The 245/65R17 product offering uses RWL, while 255/45R20 products appear in Blackwall, RWL, and Redline versions across different tire series.
Sidewall style affects the look of the vehicle as much as the tire series itself. A raised white letter treatment gives a more assertive truck or muscle-inspired presentation, while Blackwall keeps things cleaner and more understated, so the right choice depends on whether the vehicle is being kept subtle, sporty, or visually closer to a period-inspired custom look.
What brands offer tires for the 2006 Jeep Trucks Grand Cherokee?
Tire choices for the 2006 Jeep Trucks Grand Cherokee include BFGoodrich, Nitto, and Pro-Trac in the sizes that have current product availability. BFGoodrich appears in both the 245/65R17 and 255/45R20 offerings, while Nitto and Pro-Trac are present in 255/45R20 for the SRT8 front fitment.
Brand comparison matters most after the correct size is locked in. The practical differences to compare are the tire series, sidewall treatment, rim-width range where stated, and how the vehicle is actually used, rather than choosing by brand name alone or assuming that every brand offered in one size will also be available in the others.
Restoration & Appearance
Which tire should I choose for a period-style 2006 Jeep Trucks Grand Cherokee?
A period-style choice for a 2006 Jeep Trucks Grand Cherokee starts with keeping the correct size and wheel diameter for the exact sub-model. Standard trims belong in the 17-inch fitment group, while the SRT8 should retain its 20-inch staggered front-and-rear arrangement if the goal is to preserve the model’s original visual balance.
Appearance then comes down to how traditional or aggressive the tire should look. RWL can give a more assertive SUV presentation, while Blackwall offers a cleaner, more restrained finish; buyers working toward exact originality should also compare the vehicle against period photos, sales literature, or marque-specific references before settling on a sidewall style.
How does tire choice affect the appearance of a 2006 Jeep Trucks Grand Cherokee?
Tire choice changes the visual character of a 2006 Jeep Trucks Grand Cherokee more than many buyers expect. The difference between a 17-inch standard-trim fitment and the SRT8’s 20-inch staggered setup is substantial, and sidewall styles such as Blackwall, RWL, and Redline further shape whether the vehicle looks understated, truck-oriented, or more performance themed.
Keeping the correct size for the sub-model is the foundation of a balanced appearance. From there, the sidewall treatment and tire series should match the personality of the vehicle rather than fight it, especially on an SRT8 where the front and rear tires work together visually and should not be selected as unrelated stand-alone pieces.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2006 Jeep Trucks Grand Cherokee?
Yes, modifications can affect tire fitment on a 2006 Jeep Trucks Grand Cherokee even when the tire size sounds close to stock. Aftermarket wheels, changes in wheel width, altered offset, suspension lowering or lifting, and brake upgrades can all change how a tire sits in the fender opening and how much clearance it has at full steering lock.
That matters most on vehicles that no longer wear their original wheel package, and especially on the SRT8 where the 20-inch staggered setup is position-specific. A careful check of wheel diameter, actual tire size, front-to-rear placement, and visible clearance around suspension and body components is worthwhile before replacing just one pair or moving to a different series.
What should I inspect before driving a 2006 Jeep Trucks Grand Cherokee on new tires?
Before driving a 2006 Jeep Trucks Grand Cherokee on new tires, inspect the wheels for the correct diameter and condition, confirm the tires match the proper sub-model fitment, and look over valve stems, lug hardware, and overall mounting quality. It is also wise to make sure front and rear tire positions are correct on an SRT8.
A short follow-up inspection after initial road use can catch issues early. Tire pressure, any sign of rubbing, steering feel, and uneven seating on the rim deserve attention, and collector or low-mileage examples should also be checked for suspension wear, alignment drift, or old wheel damage that may not have been obvious before the tire change.
How often should tires on a 2006 Jeep Trucks Grand Cherokee be inspected?
Tires on a 2006 Jeep Trucks Grand Cherokee should be inspected regularly, not just when tread looks low. A visual check for cracking, cuts, bulges, uneven wear, and pressure loss is worthwhile before routine driving, and more thorough inspection is important when the vehicle has been stored, driven infrequently, or fitted with larger performance wheels.
Consistency matters more than waiting for a problem to become obvious. SRT8 models deserve extra attention to front and rear tire condition because the sizes are different, while standard 17-inch Grand Cherokees should still be checked for aging and wheel-condition issues that can develop quietly on older SUVs that spend long periods parked between drives.
