The 2012 GMC Trucks Yukon sits in the full-size SUV market as a truck-based vehicle built to handle family use, towing duty, and long-distance road travel with the presence and stance buyers expect from a modern Yukon. Tire choice matters here because this model spans four primary radial sizes, from 265/70R17 through 285/45R22, and fitment changes by sub-model and wheel package. That means the real decision is not simply choosing a tire, but confirming the exact Yukon configuration first. Once size is verified, the focus shifts to wheel diameter, load capability, sidewall presentation, and how the vehicle is actually used on the road.
Which Tire Size Is Right for The 2012 GMC Trucks Yukon
The 2012 GMC Trucks Yukon uses four primary tire sizes, and the right one depends on the exact sub-model and wheel setup. All of them are metric radial sizes, but they span 17-inch, 18-inch, 20-inch, and 22-inch rims, so confirming wheel diameter is the first step before comparing any tire choice.
The 275/55R20 size uses a 275-millimeter section width, a 55-series aspect ratio, radial construction, and a 20-inch rim diameter. On the 2012 GMC Trucks Yukon, this is one of the larger wheel-package fitments and is used on certain Denali, SLE, and SLT configurations. Its sizing places it in the modern SUV fitment range, where wheel diameter and overall stance are part of the package. This size should be chosen only after confirming that the Yukon is equipped with the matching 20-inch wheels rather than one of the 17-inch, 18-inch, or 22-inch setups.
The 285/45R22 size combines a 285-millimeter section width with a lower 45-series profile on a 22-inch rim. For the 2012 GMC Trucks Yukon, it applies to certain Denali, Denali Hybrid, SLE, and SLT configurations using the largest wheel diameter in this fitment group. The shorter sidewall and larger rim make wheel confirmation especially important, since this is distinct from the 17-inch, 18-inch, and 20-inch options. It is the right direction only when the vehicle already has the correct 22-inch wheel package and the rest of the chassis setup matches that fitment.
The 265/65R18 size uses a 265-millimeter section width, a 65-series aspect ratio, radial construction, and an 18-inch rim. On the 2012 GMC Trucks Yukon, this size is tied to the Yukon Hybrid, making it a configuration-specific fitment rather than a general Yukon size. The format is straightforward for modern buyers, but it still needs to be matched to the correct wheel diameter and hybrid setup. This size is the one to evaluate when the vehicle is specifically a Hybrid model and still uses its proper 18-inch wheel arrangement.
The 265/70R17 size pairs a 265-millimeter section width with a taller 70-series profile on a 17-inch rim. For the 2012 GMC Trucks Yukon, it is used on certain SLE and SLT configurations and represents the smallest rim diameter among the primary fitments for this model. Available products in this size include BFGoodrich All-Terrain T/A KO2 tires with raised white letter sidewalls, giving buyers a more truck-oriented option within the correct size. This fitment makes sense only after confirming that the Yukon is actually running the 17-inch wheel package tied to this size.
Sub-model fitment matters on the 2012 GMC Trucks Yukon because tire size changes across Denali, Hybrid, SLE, and SLT configurations. The first step is identifying the exact sub-model and wheel package, since this Yukon range uses four different radial sizes on four different rim diameters.

2012 GMC Trucks Yukon Denali
The 2012 GMC Trucks Yukon Denali uses either 275/55R20 or 285/45R22 radial tires, so the wheel package must be confirmed before choosing a replacement. Once that is established, the decision centers on staying with the correct metric size for the vehicle’s existing 20-inch or 22-inch setup.
The 2012 GMC Trucks Yukon Denali Hybrid uses the 285/45R22 radial size. Tire selection is therefore more straightforward than on multi-size sub-models, but the 22-inch wheel diameter still needs to be verified before moving ahead with any replacement choice.
The 2012 GMC Trucks Yukon Hybrid uses 265/65R18 radial tires. That makes the fitment path fairly clear, with the main task being confirmation that the vehicle still has the proper 18-inch wheels and has not been changed to a different Yukon wheel and tire package.
The 2012 GMC Trucks Yukon SLE can use 265/70R17, 275/55R20, or 285/45R22 radial tires depending on the wheel setup. Tire selection starts with confirming the actual rim diameter on the vehicle, especially if wheels have ever been changed from the original SLE configuration.
The 2012 GMC Trucks Yukon SLT also spans 265/70R17, 275/55R20, and 285/45R22 radial fitments. The practical step is to identify the current wheel package first, then compare tires within the correct size rather than assuming every SLT uses the same rim and tire combination.
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.

Owners of a 2012 GMC Trucks Yukon usually need to sort out exact tire size by sub-model and wheel diameter first. The questions below focus on fitment, radial tire selection, sidewall and brand choices, and the checks worth making before regular road use.
Tire Size & Fitment
What tire size fits a 2012 GMC Trucks Yukon?
The 2012 GMC Trucks Yukon uses four primary radial tire sizes: 265/70R17, 265/65R18, 275/55R20, and 285/45R22. The correct size depends on the exact sub-model and wheel package, so there is not one universal Yukon tire size for every 2012 configuration.
The most important first check is the wheel diameter already on the vehicle. SLE and SLT models can span several sizes, while the Hybrid and Denali Hybrid are more specific, so the safest approach is to match the tire to the actual rim size and sub-model before comparing tread style, load capacity, or appearance.
What size rim does a 2012 GMC Trucks Yukon use?
A 2012 GMC Trucks Yukon can use 17-inch, 18-inch, 20-inch, or 22-inch rims depending on the sub-model and wheel package. Those rim diameters correspond to the primary tire sizes 265/70R17, 265/65R18, 275/55R20, and 285/45R22.
Rim diameter is the key fitment checkpoint because each tire size is built for one specific wheel diameter. A Yukon with 22-inch wheels needs a very different tire than one with 17-inch wheels, so measuring or verifying the current wheels is more important than assuming fitment from the model name alone.
Why does the 2012 GMC Trucks Yukon have more than one tire size?
The 2012 GMC Trucks Yukon has more than one tire size because different sub-models and wheel packages were used across the lineup. Denali, Denali Hybrid, Hybrid, SLE, and SLT configurations do not all share the same wheel diameter, so the matching tire size changes with the setup.
That variation means the right replacement starts with the exact vehicle configuration rather than the Yukon badge alone. A buyer should confirm sub-model, inspect the wheels currently on the vehicle, and make sure any past wheel changes have not altered the original fitment before selecting a tire in one of the four sizes.
Choosing the Right Tire
What should I consider when choosing a tire for a 2012 GMC Trucks Yukon?
Start with the correct size for the exact Yukon sub-model and wheel diameter, since this model uses 17-inch, 18-inch, 20-inch, and 22-inch fitments. After size is confirmed, compare construction, load capacity, intended use, and whether the tire’s overall character suits highway driving, towing, or more truck-oriented service.
A practical comparison should also include rim-width compatibility where it is stated, along with sidewall style and any differences in tire series. On a full-size SUV like the Yukon, choosing within the correct size matters just as much as choosing the size itself, especially when replacement tires may serve very different driving priorities.
What sidewall styles are available for 2012 GMC Trucks Yukon tires?
Among the available 265/70R17 Yukon products, the sidewall style shown is RWL, meaning raised white letter. That gives this fitment a more traditional truck and SUV presentation than a plain black sidewall, while still staying within a modern radial construction.
Sidewall style is mainly an appearance decision once the correct tire size is established. It should never override fitment basics, so the better approach is to confirm the Yukon’s proper wheel diameter and tire size first, then decide whether the visual look of raised white letters matches how the vehicle is used and presented.
What brands offer tires for the 2012 GMC Trucks Yukon?
BFGoodrich is available for the 2012 GMC Trucks Yukon in the 265/70R17 size, including All-Terrain T/A KO2 options. Those tires stay within the correct radial fitment while giving buyers a recognizable truck-focused tire series to compare.
Brand choice matters most after confirming size, since a strong brand option in the wrong diameter does not solve the fitment question. On a Yukon using 265/70R17, the more useful comparison is between the available BFGoodrich specifications, including load capacity and rim-width compatibility, rather than choosing by brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 2012 GMC Trucks Yukon?
A period-style 2012 GMC Trucks Yukon still begins with the exact factory-type size format already used on the vehicle, which in this case means one of the metric radial sizes tied to the correct wheel package. Keeping the proper 17-inch, 18-inch, 20-inch, or 22-inch fitment preserves the SUV’s intended stance more effectively than chasing a different size.
Appearance choices should be made after the fitment basics are settled. A truck-oriented tire series and raised white letter sidewall can create a more traditional SUV look in 265/70R17, but buyers focused on exact originality should compare against vehicle-specific historical references and the wheel package actually installed on the Yukon.
Does correct tire fitment matter for a 2012 GMC Trucks Yukon restoration?
Correct tire fitment matters because the 2012 GMC Trucks Yukon was offered with several distinct wheel and tire combinations. Using the wrong diameter or profile can change the vehicle’s stance and presentation in obvious ways, even before any road-use concerns are considered.
A restoration-minded owner should confirm the sub-model and wheel package first, then choose a tire that matches that setup rather than selecting by appearance alone. On a later collector SUV, the right metric size does more to keep the vehicle visually coherent than an aggressive tread or sidewall style applied to the wrong wheel diameter.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2012 GMC Trucks Yukon?
Yes, modifications can affect tire fitment on a 2012 GMC Trucks Yukon, especially if the vehicle has aftermarket wheels, altered ride height, or suspension changes. Because this model already spans four rim diameters, even a small change in wheel package can move the vehicle away from its original tire size.
The smartest check is to verify the actual wheel diameter and tire size currently on the Yukon before ordering replacements. Clearance at the steering, suspension, and fender edges should also be reviewed whenever the vehicle has been changed from stock, since the correct size for one Yukon configuration is not automatically right for another.
What should I inspect before driving a 2012 GMC Trucks Yukon on new tires?
Before driving a 2012 GMC Trucks Yukon on new tires, inspect wheel condition, valve stems, inflation pressure, and basic clearance at full steering lock. The tires should match the vehicle’s correct rim diameter and show no signs of rubbing against suspension parts, liners, or body edges.
A short initial road test is worthwhile to confirm proper behavior after installation. It also helps to recheck pressure and lug torque after the first miles, while keeping an eye on any unusual vibration, pull, or contact noise that could point to a wheel, balance, or fitment issue rather than a problem with the tire itself.
How often should tires on a 2012 GMC Trucks Yukon be inspected?
Tires on a 2012 GMC Trucks Yukon should be inspected regularly for pressure, tread condition, uneven wear, cuts, bulges, and sidewall damage. A full-size SUV places real demands on its tires, so routine visual checks are more than a formality, especially when the vehicle carries passengers, cargo, or towing loads.
Monthly inspections are a sensible habit, with additional checks before longer trips. On a Yukon that sees occasional use, it is also worth watching for age-related issues and slow air loss, since a tire can look acceptable at a glance while still developing problems that affect ride quality, stability, and overall confidence on the road.
