The 2007 GMC Trucks Yukon sits in the full-size SUV market as a body-on-frame vehicle built for family hauling, towing, and everyday road use with a strong truck-based foundation. That matters when choosing tires, because this Yukon uses three different radial sizes depending on sub-model and wheel package: 265/70R17, 265/65R18, and 275/55R20. The key decision is identifying the exact Yukon configuration and confirming wheel diameter first, especially since Denali, SLE, and SLT do not all share the same primary fitment. Once the correct size is pinned down, the focus shifts to load capability, rim-width compatibility, and whether an all-terrain raised-white-letter look suits the vehicle's intended use.
Which Tire Size Is Right for The 2007 GMC Trucks Yukon
The 2007 GMC Trucks Yukon uses three primary tire sizes, and the correct one depends on sub-model and wheel diameter. Denali uses 265/65R18 or 275/55R20, while SLE and SLT use 265/70R17 or 275/55R20, so the first step is confirming the exact sub-model and whether the Yukon is riding on 17-inch, 18-inch, or 20-inch wheels before comparing tire choices.
265/65R18 is a metric radial size in which 265 refers to nominal section width in millimeters, 65 is the aspect ratio, R identifies radial construction, and 18 is the wheel diameter in inches. On the 2007 GMC Trucks Yukon, this size is part of the Denali fitment range and carries the modern road-oriented sizing format used on later full-size SUVs. It is a useful size to evaluate when keeping an 18-inch wheel setup on a Denali, and wheel confirmation should come before comparing alternative tire styles or tread types.
275/55R20 is a metric radial size with a 275-millimeter nominal section width, a 55-series profile, radial construction, and a 20-inch rim diameter. For the 2007 GMC Trucks Yukon, this size appears across multiple sub-models, making it an important fitment to verify on vehicles equipped with 20-inch wheels rather than assuming trim alone tells the full story. Its lower-profile format compared with the 17-inch and 18-inch options makes wheel-diameter confirmation especially important before replacement, particularly on Yukons that may have had wheel changes over time.
265/70R17 is a metric radial size where 265 is the nominal width in millimeters, 70 is the aspect ratio, R denotes radial construction, and 17 is the wheel diameter in inches. On the 2007 GMC Trucks Yukon, this size is used on SLE and SLT configurations and is the one product size with current tire choices here, including BFGoodrich All-Terrain T/A KO2 options with raised white letter sidewalls. It is the size to examine closely if the Yukon is intended for truck-style use, and load rating should be matched to the vehicle's actual use and wheel setup.
Tire fitment on the 2007 GMC Trucks Yukon varies by sub-model and wheel package rather than staying uniform across the range. Checking whether the vehicle is a Denali, SLE, or SLT is important, but wheel diameter still needs to be confirmed because some sub-models share the 20-inch fitment.

2007 GMC Trucks Yukon Denali
The 2007 GMC Trucks Yukon Denali uses radial tire sizing, with fitment tied to either an 18-inch or 20-inch wheel setup. That makes wheel verification the first step before choosing a replacement, especially on a Denali that may no longer be on its original wheel package.
The 2007 GMC Trucks Yukon SLE uses radial fitments that can fall on either a 17-inch or 20-inch wheel. Tire selection starts with confirming which wheel diameter is actually on the vehicle, then comparing load capacity, tread style, and intended road use within the correct size.
The 2007 GMC Trucks Yukon SLT also carries more than one radial fitment depending on wheel package, so size choice is not automatic from the trim name alone. Matching the tire to the actual wheel diameter is the practical first move before narrowing down product style and load specification.
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 Yukon Tires for Sale
Available product choices center on 265/70R17, with BFGoodrich All-Terrain T/A KO2 options in raised white letter form. The main points to compare are load specification, rim-width compatibility, and whether the Yukon is being kept in everyday road service or used more like a truck.
Owners of a 2007 GMC Trucks Yukon usually need to sort out size by sub-model and wheel diameter first, then compare radial tire choices, load specifications, appearance, and basic inspection points before putting the vehicle back on the road.
Tire Size & Fitment
What tire size fits a 2007 GMC Trucks Yukon?
The 2007 GMC Trucks Yukon uses three tire sizes: 265/70R17, 265/65R18, and 275/55R20. Denali models use 265/65R18 or 275/55R20, while SLE and SLT models use 265/70R17 or 275/55R20, and all of these are radial fitments.
The practical takeaway is that trim name alone is not enough. A Yukon that has been fitted with different factory-style wheels or later wheel changes needs the actual wheel diameter checked first, since the correct tire must match a 17-inch, 18-inch, or 20-inch rim before tread style or load range is considered.
What size rim does a 2007 GMC Trucks Yukon use?
A 2007 GMC Trucks Yukon can use 17-inch, 18-inch, or 20-inch rims depending on sub-model and wheel package. The tire sizes match those diameters directly: 265/70R17 goes on a 17-inch rim, 265/65R18 goes on an 18-inch rim, and 275/55R20 goes on a 20-inch rim.
That makes rim diameter the first thing to verify before buying tires. The size molded on the current tire sidewall is a quick reference point, but it is still smart to confirm the actual wheel size on the vehicle, especially when a Yukon has aftermarket wheels or a different package than expected.
Do all 2007 GMC Trucks Yukon sub-models use the same tire size?
No. The 2007 GMC Trucks Yukon Denali uses 265/65R18 or 275/55R20, while the SLE and SLT use 265/70R17 or 275/55R20. All three sub-models use radial tires, but they do not all share one universal size.
The shared 275/55R20 fitment can make the range look simpler than it is, but the other sizes separate the trims by wheel package. A replacement tire should be chosen only after confirming both the sub-model and the wheel diameter currently on the vehicle, since either one can change the correct fitment path.
Choosing the Right Tire
What should I consider when choosing a 265/70R17 tire for a 2007 GMC Trucks Yukon?
Start with the basics: 265/70R17 is a radial size used on certain 2007 GMC Trucks Yukon SLE and SLT configurations with 17-inch wheels. The available choices here are BFGoodrich All-Terrain T/A KO2 tires, so the main product differences are load specification, pressure rating, weight, and the same 7.0 to 9.0 inch rim-width range.
Selection should follow how the Yukon is actually used. A lightly used street vehicle may not need the same load reserve as one that sees towing, cargo, or rougher service, and the wheel setup still has to match the tire. Checking the existing wheel width and comparing the tire's service requirements is the smart next step.
What sidewall styles are available for 2007 GMC Trucks Yukon tires?
The available 265/70R17 product choices for the 2007 GMC Trucks Yukon use an RWL sidewall, which means raised white letters. That gives the Yukon a more truck-oriented look than a plain blackwall presentation and fits the all-terrain character of the BFGoodrich KO2 line offered in this size.
Sidewall style is partly an appearance decision, but it also helps signal the tire's overall personality. On a Yukon kept close to stock for daily road use, some owners may prefer a cleaner look, while others want the more traditional SUV and light-truck visual presence that raised white letters provide.
What brands offer tires for the 2007 GMC Trucks Yukon?
The current product selection for this 2007 GMC Trucks Yukon fitment includes BFGoodrich in 265/70R17. Those tires are part of the All-Terrain T/A KO2 series and are offered with raised white letter sidewalls in more than one load specification.
Brand choice is only one part of the decision. The more important comparison is whether the tire matches the Yukon’s actual size, wheel width, and intended use, since one 265/70R17 can differ meaningfully from another in load capacity and service pressure even within the same overall tire line.
Restoration & Appearance
Does correct tire fitment matter for a 2007 GMC Trucks Yukon restoration?
Yes. Even though a 2007 GMC Trucks Yukon is a newer vehicle than a traditional antique or muscle car, correct tire fitment still matters for maintaining the right stance, wheel relationship, and overall presentation. The Yukon’s fitments are tied to specific wheel diameters, so size choice affects both appearance and practicality.
A restoration-oriented approach should begin with the actual sub-model and wheel package on the vehicle, then move to tire style and sidewall presentation. If originality is an important goal, vehicle-specific sales literature, factory documentation, and marque resources are useful references before settling on a replacement size or look.
How does tire construction affect the appearance of a restored 2007 GMC Trucks Yukon?
On the 2007 GMC Trucks Yukon, construction is straightforward because the primary fitments are radial sizes. That means the appearance differences are shaped less by bias-ply versus radial choice and more by size, sidewall profile, wheel diameter, and sidewall treatment such as raised white letters.
A Yukon restored with stock-style wheels will look most balanced when the tire size matches the wheel package it was meant to carry. Moving from a 17-inch setup to an 18-inch or 20-inch setup changes the visual character noticeably, so the tire should support the intended look rather than forcing it.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2007 GMC Trucks Yukon?
Yes. A 2007 GMC Trucks Yukon can be affected by aftermarket wheels, suspension changes, leveling or lowering kits, and body or fender alterations. Those changes can influence which of the Yukon’s original fitment sizes still make sense and whether a tire clears properly during steering and suspension movement.
The safest approach is to verify actual wheel diameter and width first, then compare the current setup to the tire size being considered. Clearance at full lock, suspension travel, and load needs all matter, especially on a full-size SUV that may carry passengers, cargo, or towing duties.
What should I inspect before driving a 2007 GMC Trucks Yukon on new tires?
Before putting a 2007 GMC Trucks Yukon into regular use on new tires, inspect wheel condition, valve stems, air pressure, and lug hardware, and make sure the tire size matches the wheel diameter on the vehicle. It is also wise to check for uneven wear patterns that might point to alignment or suspension issues.
A new tire cannot correct worn steering or suspension components by itself. Looking over shocks, bushings, ball joints, and brake condition helps the Yukon make full use of the replacement tires, and a short initial road test can confirm that there is no rubbing, vibration, or abnormal pull.
How often should tires on a 2007 GMC Trucks Yukon be inspected?
Tires on a 2007 GMC Trucks Yukon should be inspected regularly, not just at replacement time. Pressure, tread wear, cuts, cracking, bulges, and signs of air loss are all worth checking, especially on a vehicle that may alternate between daily use, towing duty, and longer periods of sitting.
A quick visual check every month is a sensible routine, with a closer inspection before road trips or heavier use. Tire condition matters as much as tread depth on an SUV, and uneven wear can also reveal alignment, inflation, or suspension problems before they turn into a larger fitment or handling issue.
