The 2017 GMC Trucks Yukon sits in the full-size SUV market where towing ability, passenger space, and long-distance comfort matter just as much as curb presence. In this generation, the Yukon blends traditional body-on-frame utility with a more refined road feel, so tire choice affects both stance and everyday usability. This model uses radial tires, with fitments in 265/65R18, 275/55R20, and 285/45R22 depending on sub-model and wheel package. That means the key decision is not simply brand selection, but confirming the exact wheel diameter and tire size your Yukon carries. For replacement, appearance, ride profile, and wheel compatibility all need to stay aligned with the vehicle’s actual setup.
Which Tire Size Is Right for The 2017 GMC Trucks Yukon
Three tire sizes apply to the 2017 GMC Trucks Yukon, and they vary by sub-model and wheel diameter rather than by construction, since all are radial fitments. The first step is confirming whether your Yukon is equipped with 18-inch, 20-inch, or 22-inch wheels, then matching that with the exact sub-model and current wheel setup before choosing a replacement tire.
The size 275/55R20 identifies a metric radial tire that is 275 millimeters wide, uses a 55-series aspect ratio, and fits a 20-inch rim. On the 2017 GMC Trucks Yukon, this is one of the main radial fitments and it suits buyers looking for a balance between full-size SUV proportions and a substantial wheel package. This size often becomes the middle ground in the Yukon lineup because it avoids the smaller 18-inch setup and the larger 22-inch presentation. It is the right size to evaluate when your Yukon already runs 20-inch wheels and you want to preserve the vehicle’s intended overall stance.
The size 285/45R22 is a metric radial format, with a 285-millimeter section width, a 45-series profile, and a 22-inch rim diameter. On the 2017 GMC Trucks Yukon, this size is tied to the largest wheel fitment in the range and gives the vehicle a more assertive, large-wheel appearance. Its lower profile compared with the 18-inch and 20-inch options makes wheel confirmation especially important before replacement. This is the size to focus on when the Yukon is already equipped with 22-inch wheels and the goal is to keep the same visual proportion and fitment approach.
The size 265/65R18 uses the modern metric radial system, meaning a 265-millimeter width, a 65-series aspect ratio, and an 18-inch rim. For the 2017 GMC Trucks Yukon, this fitment belongs to the smaller wheel setup among the available sizes and maintains the same radial construction used across the range. Because it differs from the 20-inch and 22-inch choices by rim diameter, it should not be selected by appearance alone. This size deserves attention when your Yukon carries 18-inch wheels and you want to keep the established wheel-and-tire relationship already on the vehicle.
Tire fitment on the 2017 GMC Trucks Yukon depends on the exact sub-model and wheel package, not just the model name on the liftgate. Denali, SLE, and SLT can overlap in size choices, so confirming the actual wheel diameter on the vehicle is the most important step before selecting tires.

2017 GMC Trucks Yukon Denali
The 2017 GMC Trucks Yukon Denali uses 20-inch or 22-inch radial tire fitments rather than the 18-inch setup found elsewhere in the Yukon range. That makes wheel confirmation especially important, since replacement choice centers on preserving the correct diameter and profile for the vehicle’s current configuration.
The 2017 GMC Trucks Yukon SLE spans all three Yukon tire sizes, including 18-inch, 20-inch, and 22-inch radial fitments. Tire selection starts with identifying the wheel diameter actually on the vehicle, then matching the replacement size to that setup rather than assuming every SLE uses the same tire.
The 2017 GMC Trucks Yukon SLT also appears with 18-inch, 20-inch, or 22-inch radial tire sizes. Because more than one size applies to this sub-model, the practical step is to verify the existing wheel-and-tire combination before choosing a replacement based on appearance or trim level alone.
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.
Frequently Asked Questions
For the 2017 GMC Trucks Yukon, the main questions usually come down to exact tire size, wheel diameter, sub-model overlap, and how to choose the right replacement once the vehicle’s current setup is confirmed.
Tire Size & Fitment
What tire size fits a 2017 GMC Trucks Yukon?
The 2017 GMC Trucks Yukon uses three radial tire sizes: 265/65R18, 275/55R20, and 285/45R22. The correct one depends on the exact sub-model and wheel package, with Denali using 20-inch or 22-inch fitments, while SLE and SLT can use 18-inch, 20-inch, or 22-inch sizes.
The most important step is to confirm the wheel diameter currently on the vehicle before choosing a replacement tire. Since all three sizes belong to the same Yukon model line, it is easy to assume they interchange freely, but the rim diameter must match and the vehicle should be checked for its actual wheel setup if anything has been changed previously.
What size rim does a 2017 GMC Trucks Yukon use?
A 2017 GMC Trucks Yukon can use 18-inch, 20-inch, or 22-inch rims depending on sub-model and tire size. The 265/65R18 tire fits an 18-inch rim, the 275/55R20 fits a 20-inch rim, and the 285/45R22 fits a 22-inch rim.
Rim diameter should be confirmed before anything else because it determines which tire size is even possible to mount. A buyer looking at replacement tires should also make sure the wheels on the Yukon are the ones actually being used now, especially if the SUV was purchased used or may have had wheel upgrades installed at some point.
Do all 2017 GMC Trucks Yukon sub-models use the same tire size?
No, the 2017 GMC Trucks Yukon sub-models do not all use the same tire size. Denali uses 275/55R20 and 285/45R22, while SLE and SLT can use 265/65R18, 275/55R20, or 285/45R22 depending on the wheel package.
That overlap makes it important to identify both the sub-model and the wheel diameter before replacing tires. A Yukon owner should not choose a size based only on trim name, because SLE and SLT cover more than one fitment. Checking the existing sidewall size and wheel diameter is the quickest way to avoid ordering the wrong tire.
Choosing the Right Tire
What should I consider when choosing a tire for a 2017 GMC Trucks Yukon?
Start with the correct size for the vehicle’s actual wheel setup: 265/65R18, 275/55R20, or 285/45R22. Since the 2017 GMC Trucks Yukon uses radial tires across all fitments, the decision usually centers on matching the right wheel diameter first and then selecting a tire that suits how the SUV is driven and loaded.
A practical replacement choice should account for the Yukon’s full-size SUV role, including everyday road use, passenger carrying, and any towing or cargo demands. It also helps to compare the current wheels on the vehicle against the trim level, because used vehicles are often changed over time and the installed setup may not match the original sub-model pattern.
How do I choose between the available 2017 GMC Trucks Yukon tire sizes?
The available sizes are not alternatives to choose from freely unless the Yukon already has the matching wheel diameter. A 265/65R18 belongs on an 18-inch rim, a 275/55R20 on a 20-inch rim, and a 285/45R22 on a 22-inch rim, so the real choice starts with the wheel package on the SUV.
Once that is confirmed, the next step is deciding whether to preserve the vehicle’s current look and profile or change the entire wheel-and-tire setup intentionally. Buyers comparing used Yukons should remember that trim levels overlap in fitment, so reading the tire sidewall and measuring the wheel diameter is more reliable than assuming the trim name answers the question by itself.
What rim-width specifications should I compare when choosing 2017 GMC Trucks Yukon tires?
Rim width matters because tire sizing is built around a compatible wheel range, even when the tire diameter is correct. On a 2017 GMC Trucks Yukon, the first priority is still matching the tire to the installed 18-inch, 20-inch, or 22-inch wheel, but width should also be confirmed before mounting a replacement.
This becomes especially important if the Yukon has aftermarket wheels or if the original wheels have been replaced with a different width than stock. A tire can share the correct diameter and still be a poor match for the wheel, so checking the wheel’s actual width helps protect handling, sidewall shape, and overall fitment confidence.
Restoration & Appearance
Does correct tire fitment matter for a 2017 GMC Trucks Yukon restoration?
Yes, correct tire fitment still matters on a 2017 GMC Trucks Yukon restoration or preservation project, even though this is a modern full-size SUV rather than a classic bias-ply application. Keeping the correct size relationship between tire and wheel helps maintain the Yukon’s intended stance, proportions, and road-ready appearance.
A restoration-minded owner should verify whether the vehicle is wearing 18-inch, 20-inch, or 22-inch wheels and then stay with the corresponding tire size unless there is a deliberate plan to change the setup. If originality is especially important, comparing the vehicle against factory literature, window sticker records, or marque-specific references is worthwhile before making changes.
How does tire construction affect the appearance of a restored 2017 GMC Trucks Yukon?
On the 2017 GMC Trucks Yukon, construction is straightforward because all primary fitments are radial. That means appearance is influenced more by the exact size and wheel diameter than by a bias-ply-versus-radial decision, especially since the Yukon’s available fitments span 18-inch, 20-inch, and 22-inch wheels.
For a restoration-oriented result, preserving the correct tire size for the wheel package usually has more visual impact than anything else. An 18-inch setup, a 20-inch setup, and a 22-inch setup each give the Yukon a different overall presentation, so the right approach is to confirm how the vehicle was equipped and match that arrangement carefully.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 GMC Trucks Yukon?
Yes, modifications can affect tire fitment on a 2017 GMC Trucks Yukon. Wheel swaps, suspension changes, leveling kits, lowering, and body alterations can all change the space available for 265/65R18, 275/55R20, or 285/45R22 tires, even when the replacement appears close to the size already on the vehicle.
That is why the current setup should be checked before replacing tires, especially on a used Yukon. Wheel diameter is only part of the equation, since wheel width, offset, steering clearance, and fender clearance also matter. Any owner dealing with a modified SUV should inspect those areas carefully before assuming the original fitment pattern still applies.
What should I inspect before driving a 2017 GMC Trucks Yukon on new tires?
Before driving a 2017 GMC Trucks Yukon on new tires, inspect the wheels for damage, confirm the tire size matches the wheel diameter, and make sure each tire is mounted and inflated properly. It is also worth checking for any uneven suspension wear or alignment issues that may have affected the previous tires.
A short visual inspection after installation can help catch rubbing, unusual sidewall clearance, or contact near the fenders and steering components. The Yukon is a full-size SUV, so it also makes sense to watch for air loss, vibration, or irregular wear during early driving. Those checks matter even more if the vehicle carries passengers, cargo, or towing loads.
How often should tires on a 2017 GMC Trucks Yukon be inspected?
Tires on a 2017 GMC Trucks Yukon should be inspected regularly, not just when tread looks low. A good routine includes checking pressure, tread wear, cuts, bulges, cracking, and any sign of uneven wear pattern, especially because a full-size SUV places meaningful demands on its tires during normal road use.
Inspection becomes even more important when the Yukon is driven infrequently, stored for long periods, or used for heavier family, cargo, or towing duty. Owners should also recheck the tires after pothole impacts, curb contact, or wheel changes. Catching problems early helps preserve ride quality and can prevent a small issue from becoming a larger fitment or safety concern.
