The 2007 GMC Trucks Envoy came from the final stretch of the body-on-frame midsize SUV era, offering the upright stance, towing capability, and everyday utility that kept trucks like this popular well into the 2000s. Buyers looking at one today are often balancing practical road use with the need to keep the truck’s stance and wheel setup true to its trim. Tire fitment centers on two radial sizes, 245/60R18 and 245/65R17, with size choice tied to sub-model and wheel diameter. That makes this a wheel-and-trim verification exercise first, then a decision about tread style and intended use. Getting that right helps preserve both appearance and drivability.
Which Tire Size Is Right for The 2007 GMC Trucks Envoy
The 2007 GMC Trucks Envoy uses two primary tire sizes, and the right one depends on both sub-model and wheel diameter. Both fitments are radial, but one uses a 17-inch rim and the other uses an 18-inch rim, so the first step is confirming the exact wheel setup on the truck before comparing tire choices.
In 245/60R18, the 245 identifies nominal section width in millimeters, the 60 is the aspect ratio, the R indicates radial construction, and the 18 is the rim diameter in inches. This is a modern metric radial fitment used on 18-inch Envoy wheel applications, including the Denali and some SLE and SLT configurations. Its overall dimensions keep it very close in height to the 245/65R17 option while matching a different wheel diameter. This size is the one to evaluate when the truck already carries 18-inch wheels and the goal is to keep the correct wheel-and-tire relationship.
In 245/65R17, the 245 is the nominal section width in millimeters, 65 is the aspect ratio, R means radial construction, and 17 identifies the rim diameter in inches. This size belongs on 17-inch Envoy applications and appears on certain SLE and SLT setups rather than across the full model range. Available product choice in this size includes a BFGoodrich All-Terrain T/A KO2 with raised white letter styling and an all-terrain character. This is the size to focus on when the truck has 17-inch wheels and a more utility-oriented tread design is part of the decision.
Sub-model fitment is not uniform across the 2007 GMC Trucks Envoy range. Denali uses one tire size, while SLE and SLT can use either of the two primary sizes, so confirming the exact sub-model and wheel diameter matters before selecting tires.

2007 GMC Trucks Envoy Denali
The 2007 GMC Trucks Envoy Denali uses the 245/60R18 radial tire size. Tire selection here starts with keeping the 18-inch wheel fitment intact, then choosing a tire that suits how the vehicle is driven and the appearance you want to maintain.
The 2007 GMC Trucks Envoy SLE can use either 245/60R18 or 245/65R17, both in radial construction. That makes wheel confirmation especially important, since the tire choice needs to match the actual 17-inch or 18-inch setup currently on the vehicle.
The 2007 GMC Trucks Envoy SLT also appears with either 245/60R18 or 245/65R17 radial tires. Selection depends on the truck’s actual wheel diameter first, then on whether the priority is a standard road-going fitment or a more aggressive tread style within the correct size.
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 2007 GMC Trucks Envoy Tires for Sale

Common 2007 GMC Trucks Envoy tire questions usually come down to the correct size for the truck’s sub-model and wheels, how to compare available radial options, and what to inspect before putting an older SUV back into regular road use.
Tire Size & Fitment
What tire size fits a 2007 GMC Trucks Envoy?
The 2007 GMC Trucks Envoy uses two primary tire sizes: 245/60R18 and 245/65R17. Both are radial sizes, but they do not use the same wheel diameter, so they are tied to different wheel setups within the Envoy range rather than being interchangeable as one universal fitment.
Choosing between them starts with the truck’s actual wheels and sub-model. Denali uses 245/60R18, while SLE and SLT can appear with either size. Checking the wheel diameter on the vehicle is the quickest way to narrow the choice before comparing tread style, rim-width compatibility, and overall intended use.
What size rim does a 2007 GMC Trucks Envoy use?
A 2007 GMC Trucks Envoy uses either a 17-inch or 18-inch rim, depending on the tire size and configuration. The 245/65R17 fitment uses a 17-inch rim, while the 245/60R18 fitment uses an 18-inch rim, so rim diameter is a core part of correct tire selection on this SUV.
That matters because a tire must match the wheel’s diameter exactly. Looking at the sidewall is helpful, but physically confirming the wheel setup on the truck is even better, especially on an older Envoy that may have had wheels changed. Once rim diameter is confirmed, the rest of the selection process becomes much more straightforward.
Do all 2007 GMC Trucks Envoy sub-models use the same tire size?
No. The 2007 GMC Trucks Envoy Denali uses 245/60R18, while the SLE and SLT can use either 245/60R18 or 245/65R17. That means the Envoy line does not share one universal tire size across every covered sub-model, even though all of the fitments are radial.
For a buyer or owner, that makes trim identification more than a naming detail. It helps narrow the expected wheel-and-tire combination before purchase. On SLE and SLT models especially, verifying the actual wheels on the truck is still important, since the same sub-model can appear with either 17-inch or 18-inch tire fitment.
Choosing the Right Tire
What should I consider when choosing a 245/65R17 tire for a 2007 GMC Trucks Envoy?
Start with correct size, radial construction, and wheel compatibility. For the 2007 GMC Trucks Envoy, a 245/65R17 tire belongs on a 17-inch wheel, and the available BFGoodrich All-Terrain T/A KO2 in this size is built for a 7.0- to 8.0-inch rim-width range with a raised white letter sidewall treatment.
Beyond size, think about how the Envoy is actually used. An all-terrain tire can suit drivers who want a more rugged look or mixed-use capability, but it also changes the truck’s visual character compared with a more road-oriented tire. Matching the tread style to the vehicle’s use keeps the selection practical rather than purely cosmetic.
What sidewall styles are available for 2007 GMC Trucks Envoy tires?
Among the currently available options for the 2007 GMC Trucks Envoy, the visible sidewall style is RWL, or raised white letter, in 245/65R17. Sidewall treatment affects the truck’s presentation just as much as tread design, especially on an SUV where the tires are a strong visual part of the overall stance.
Raised white letters tend to give the Envoy a more assertive, utility-oriented appearance than a plain black sidewall. That can work especially well if the truck has a more rugged setup or if the owner wants a stronger period-appropriate 2000s truck look. The important step is still making sure the sidewall style is attached to the correct tire size.
What brands offer tires for the 2007 GMC Trucks Envoy?
The currently available product coverage for the 2007 GMC Trucks Envoy includes BFGoodrich in 245/65R17. That option is the All-Terrain T/A KO2, which combines radial construction with raised white letter styling and an all-terrain series character rather than a purely highway-oriented presentation.
Brand matters less than matching the product to the correct Envoy wheel setup and intended use. A tire for 17-inch applications should not be treated as a substitute for the 18-inch fitment. Once size and wheel diameter are confirmed, comparing sidewall appearance, tread type, load specification, and rim-width range becomes far more useful.
Restoration & Appearance
Which tire should I choose for a period-style 2007 GMC Trucks Envoy?
A period-style 2007 GMC Trucks Envoy starts with keeping the correct size for the truck’s wheel setup: 245/60R18 or 245/65R17, depending on configuration. On a vehicle from this era, the right overall look usually comes from preserving the proper wheel diameter and avoiding a tire that visually overwhelms or underfills the factory-style stance.
For a more utility-focused appearance, the available 245/65R17 BFGoodrich All-Terrain T/A KO2 adds a distinctly truck-oriented look. Owners aiming for a more original presentation may prefer to compare tread and sidewall style carefully against period photos, sales literature, or marque-specific references before deciding what looks most at home on the vehicle.
Does correct tire fitment matter for a 2007 GMC Trucks Envoy restoration?
Yes, correct tire fitment matters on a 2007 GMC Trucks Envoy restoration because wheel diameter and tire proportion have a strong effect on how the SUV sits and presents. Using the proper 17-inch or 18-inch fitment helps preserve the intended stance and avoids turning the tire choice into a visual mismatch.
Appearance is only part of the picture. Correct fitment also keeps the selection grounded in practical wheel compatibility and normal clearance expectations. On a restored or well-kept Envoy, it makes sense to confirm the exact sub-model, inspect whether the wheels are original-style or changed later, and then choose the tire size that matches that setup.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2007 GMC Trucks Envoy?
Yes. Changes such as aftermarket wheels, different wheel widths, suspension lowering or lifting, and body or fender alterations can all affect tire fitment on a 2007 GMC Trucks Envoy. That is especially important here because the vehicle already appears with both 17-inch and 18-inch tire sizes depending on configuration.
A modified Envoy should be checked as it sits, not only by trim name. Wheel diameter, wheel width, and available clearance at full steering lock all matter before choosing tires. Even when the tire size matches the sidewall label you expect, a changed wheel or suspension setup can alter what works comfortably on the vehicle.
What should I inspect before driving a 2007 GMC Trucks Envoy on new tires?
Before driving a 2007 GMC Trucks Envoy on new tires, inspect the wheels for damage, confirm the correct rim diameter, and make sure the tires are mounted in the proper size for the truck’s setup. It also helps to check valve stems, lug hardware, and basic suspension condition so the new tires are not compromised immediately.
A road-use check should also include tire pressure, visible clearance around the fenders and suspension, and a quick look for uneven wear patterns that could point to alignment or worn front-end parts. On an older SUV, those surrounding components often influence how well a new set of tires actually performs once the truck is back on the road.
How often should tires on a 2007 GMC Trucks Envoy be inspected?
Tires on a 2007 GMC Trucks Envoy should be inspected regularly, not only at service intervals. A monthly check is a sensible routine for pressure, tread wear, cuts, bulges, and sidewall cracking, and any Envoy that sits for long periods deserves extra attention because age and storage conditions can matter as much as mileage.
Inspections should become more thorough before a longer trip or after the vehicle has been parked for an extended time. Looking at air loss, uneven wear, and signs of rubbing can help catch fitment or mechanical issues early. That approach is especially useful on older SUVs whose wheels, suspension parts, or prior modifications may no longer be exactly as expected.
