The 2014 GMC Trucks Yukon sits at the end of the long-running full-size SUV formula that made these trucks popular for towing, family hauling, and everyday road use. It blends body-on-frame utility with the broad, planted stance buyers expect from a traditional GMC sport utility. Tire fitment matters here because this Yukon uses three different radial sizes across its covered configurations: 265/70R17, 275/55R20, and 285/50R20. That means the first step is confirming the exact sub-model and wheel diameter, then narrowing the choice by intended use, especially when comparing a highway-oriented setup with the available BFGoodrich All-Terrain T/A KO2 option in 265/70R17.
Which Tire Size Is Right for The 2014 GMC Trucks Yukon
The 2014 GMC Trucks Yukon uses three primary tire sizes, and they do not all apply to the same configurations. The most important first step is confirming both the exact sub-model and whether the truck is on a 17-inch or 20-inch wheel, since size choice changes with the wheel setup. Once that is clear, the decision shifts to selecting the right radial tire for the vehicle's intended use and appearance.
275/55R20 is a modern metric radial size in which 275 is the nominal section width in millimeters, 55 is the aspect ratio, R identifies radial construction, and 20 is the wheel diameter in inches. On the 2014 GMC Trucks Yukon, this size belongs to 20-inch wheel applications and serves as one of the main fitments across multiple sub-models. It is a useful size to evaluate when the truck already wears 20-inch wheels and a balanced factory-style overall tire profile is important. Wheel confirmation should come before any selection, especially on vehicles that may have had wheel changes over time.
285/50R20 is also a modern metric radial size, with a 285-millimeter nominal section width, a 50-series profile, radial construction, and a 20-inch rim diameter. For the 2014 GMC Trucks Yukon, this size is tied to specific 20-inch applications rather than the full model range. Its slightly lower-profile format compared with a 55-series size makes exact wheel setup especially important before choosing a replacement. Buyers should match this size to the correct Yukon configuration first, then compare tire details such as load specification, road-use needs, and overall tire character.
265/70R17 is a metric radial size where 265 is the nominal section width in millimeters, 70 is the aspect ratio, R means radial, and 17 is the wheel diameter in inches. On the 2014 GMC Trucks Yukon, it applies to 17-inch wheel configurations and appears on certain SLE and SLT setups. Available products in this size include BFGoodrich All-Terrain T/A KO2 tires with raised white letter sidewalls, giving this fitment a more truck-oriented selection path than the 20-inch sizes. It is the size to focus on when maintaining a 17-inch wheel package and comparing load capacity, rim-width compatibility, and all-terrain styling.
Sub-model fitment on the 2014 GMC Trucks Yukon is not uniform, so identifying the exact trim matters before choosing a tire. Denali uses 20-inch tire sizes only, while SLE and SLT can appear with either 17-inch or 20-inch fitment depending on the wheel setup.

2014 GMC Trucks Yukon Denali
The 2014 GMC Trucks Yukon Denali uses 20-inch radial tire sizes, making wheel diameter the first thing to confirm before replacement. Once the wheel setup is verified, the choice becomes matching the correct 20-inch size to the vehicle and intended road use rather than treating all Yukon sizes as interchangeable.
The 2014 GMC Trucks Yukon SLE can use either a 17-inch or 20-inch radial tire setup, so trim name alone is not enough to select a tire. Checking the actual wheels on the vehicle helps separate the correct fitment from the other SLE possibility before comparing tread style or load specification.
The 2014 GMC Trucks Yukon SLT also appears with either 17-inch or 20-inch radial fitment, which makes the current wheel package a key part of tire selection. That is especially important on vehicles that may have had replacement wheels installed, since the right tire starts with the actual rim diameter on the truck.
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.

These FAQs focus on the tire sizes used on the 2014 GMC Trucks Yukon, how sub-model and wheel choices affect fitment, and what to check when comparing available tires for regular road use or a more truck-oriented setup.
Tire Size & Fitment
What tire size fits a 2014 GMC Trucks Yukon?
The 2014 GMC Trucks Yukon uses three radial tire sizes: 265/70R17, 275/55R20, and 285/50R20. The correct size depends on the exact sub-model and wheel package, so there is not one universal tire size across every Yukon configuration covered here.
The most important step is confirming the actual wheel diameter on the vehicle before ordering a replacement tire. Denali uses 20-inch sizes, while SLE and SLT can appear with either 17-inch or 20-inch fitment, so checking the truck itself is more reliable than assuming all trims use the same tire.
What size rim does a 2014 GMC Trucks Yukon use?
The 2014 GMC Trucks Yukon uses either a 17-inch or 20-inch rim, depending on the tire size and configuration. The 265/70R17 tire fits a 17-inch wheel, while both 275/55R20 and 285/50R20 fit 20-inch wheels.
That rim diameter difference is the first fitment detail to verify because a 17-inch tire and a 20-inch tire are not interchangeable. If the Yukon has had wheel changes at any point, confirm the actual wheel size on the truck before comparing tires, then match the tire size to that wheel and the correct trim setup.
Do all 2014 GMC Trucks Yukon sub-models use the same tire size?
No. The 2014 GMC Trucks Yukon Denali uses 20-inch tire sizes, while the SLE and SLT can use either 265/70R17 or 275/55R20. That means sub-model alone does not always settle the fitment question unless the wheel package is also confirmed.
This matters most when replacing tires on an SLE or SLT, because either a 17-inch or 20-inch setup may be present. A quick check of the current tire sidewall or wheel diameter will usually narrow the correct fitment immediately and help avoid comparing products that belong to a different Yukon configuration.
Choosing the Right Tire
What should I consider when choosing a 265/70R17 tire for a 2014 GMC Trucks Yukon?
Start with the correct size, radial construction, and 17-inch wheel requirement. In 265/70R17, available Yukon options include BFGoodrich All-Terrain T/A KO2 tires, so useful comparison points include load specification, rim-width compatibility, sidewall presentation, and whether the tire's overall character suits how the SUV is actually used.
A Yukon driven mainly on pavement may call for a different feel than one that sees more rough-surface or utility use, even within the same size. It also helps to compare the current wheel width and the vehicle's intended cargo or towing demands so the selected tire matches both the truck and its day-to-day role.
What sidewall styles are available for 2014 GMC Trucks Yukon tires?
In the currently available 265/70R17 Yukon products, the sidewall style is RWL, or raised white letter. That gives this fitment a more traditional truck appearance than a plain black sidewall and can make a visible difference in how the vehicle presents, especially on a full-size SUV.
Sidewall style should be treated as an appearance choice within the correct tire size, not as a substitute for fitment. Once the Yukon is confirmed to use 265/70R17 on a 17-inch wheel, the raised white letter look becomes one of the selection details to weigh alongside load rating, rim-width range, and intended use.
What brands offer tires for the 2014 GMC Trucks Yukon?
Within the currently available products for this Yukon fitment, BFGoodrich is represented in 265/70R17. Those tires are from the All-Terrain T/A KO2 series, which gives buyers a clearly truck-oriented option in the 17-inch Yukon application.
Brand is only one part of the decision, so it still makes sense to compare the exact size, wheel compatibility, sidewall treatment, and load specification before choosing a tire. On a Yukon with multiple possible factory size paths, confirming the right wheel diameter and tire size should come before narrowing the choice by brand.
Restoration & Appearance
Which tire should I choose for a period-style 2014 GMC Trucks Yukon?
A period-style choice for a 2014 GMC Trucks Yukon usually starts with keeping the correct original size family for the truck's actual wheel package, whether that is 265/70R17, 275/55R20, or 285/50R20. Staying with the proper size and wheel diameter preserves the SUV's intended stance more effectively than chasing a look through an incorrect fitment.
Appearance details come next. On 17-inch applications, an RWL all-terrain tire creates a distinctly truck-oriented presentation, while the 20-inch sizes support a more modern full-size SUV look. If originality matters beyond general period style, compare the vehicle against window-sticker, dealer, or marque-specific references before making a final cosmetic decision.
Does correct tire fitment matter for a 2014 GMC Trucks Yukon restoration?
Yes, correct tire fitment matters because it affects both appearance and the way the restored Yukon sits on its wheels. Using the right diameter and size family helps maintain the proper visual balance, especially on a full-size GMC SUV where wheel-and-tire proportions are easy to notice.
Fitment accuracy also prevents the restoration from drifting into avoidable clearance or wheel-compatibility problems. Matching the tire to the actual 17-inch or 20-inch wheel package is the first step, and after that the focus can move to details like sidewall style, tread character, and overall presentation without compromising the basic setup.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2014 GMC Trucks Yukon?
Yes. Wheel changes, suspension alterations, leveling or lowering kits, and other modifications can affect tire fitment on a 2014 GMC Trucks Yukon even when the tire size seems close to the original specification. The biggest concerns are wheel diameter, wheel width, offset, and available clearance during turning and suspension movement.
A Yukon that has been altered should be checked as it sits rather than assumed to match stock fitment. Looking at the current wheel dimensions and inspecting for clearance around the fenders, steering components, and suspension helps prevent choosing a tire that belongs to the model line in general but not to that particular truck.
What should I inspect before driving a 2014 GMC Trucks Yukon on new tires?
Before putting a 2014 GMC Trucks Yukon into regular service on new tires, inspect the wheels for damage, confirm the tire size matches the wheel diameter, and make sure the tires are inflated appropriately for the application. It also helps to check lug torque, valve stems, tread seating, and any sign of rubbing at full steering lock.
A short follow-up inspection after the first miles is worthwhile, especially on a heavier SUV. Recheck pressure, look for uneven contact or unexpected clearance marks, and pay attention to vibration or pull. Catching those issues early helps confirm the tire and wheel setup is working properly before longer trips or heavier use.
How should tires on a 2014 GMC Trucks Yukon be inspected and maintained?
Tires on a 2014 GMC Trucks Yukon should be inspected regularly for air loss, uneven tread wear, cuts, cracking, bulges, and embedded debris. Because this is a full-size SUV, keeping pressures consistent and watching wear patterns across all four tires is especially important for stability, tread life, and predictable road behavior.
Routine maintenance should also include checking alignment symptoms, rotating tires as appropriate for the setup, and inspecting the wheels for impact damage. On a Yukon that sees occasional use, it is smart to look at tire condition before every longer drive instead of relying only on mileage, since age and storage conditions also affect tire health.
