2016 GMC Trucks Tire Fitment Guide

2016 GMC Trucks vehicles use eighteen radial sizes across eight model lines. Acadia uses 255/55R20, 255/65R18, and 255/60R19; Canyon uses 265/70R16, 255/65R17, and 265/60R18; Sierra 1500 uses 255/70R17, 265/70R17, 275/55R20, 285/45R22, and 265/65R18; Sierra 2500 HD uses 245/75R17, 265/70R18, and 265/60R20; Sierra 3500 HD uses 235/80R17 and 265/70R18; Terrain uses 235/55R18, 235/55R19, and 225/65R17; Yukon and Yukon XL use 275/55R20, 285/45R22, and 265/65R18.

Wheel diameters span 16 through 22 inches, so the most important first check is the actual wheel on the vehicle, not just the badge on the tailgate. Several sizes are shared only among related full-size trucks and SUVs, while many are unique to one model line. That means a 2016 GMC Trucks owner should verify model and wheel diameter together before comparing tread design, load rating, or sidewall appearance.

On a 2016 GMC Trucks tire, 265/70R17 is a metric radial size. The 265 is the nominal section width in millimeters, 70 is the aspect ratio, meaning the sidewall height is 70 percent of the section width, the R identifies radial construction, and 17 is the wheel diameter in inches. Within the 2016 GMC lineup, that size belongs to the Sierra 1500.

That decoding matters because a size can look close to another GMC size on paper while still requiring a different wheel diameter or carrying a different overall height and load capability. For the 2016 GMC Trucks Sierra 1500, 265/70R17 also appears in more than one load version, so the sidewall marking deserves a second look even after the basic size has been confirmed.

No, 2016 GMC Trucks models do not share one common tire size. The Acadia, Terrain, Canyon, Sierra 1500, Sierra 2500 HD, Sierra 3500 HD, Yukon, and Yukon XL each use their own size groups, and only a few sizes overlap between related models. Sierra 1500 shares 275/55R20, 285/45R22, and 265/65R18 with Yukon and Yukon XL, while Sierra 2500 HD shares 265/70R18 with Sierra 3500 HD.

That variation means year and make alone are not enough for a safe replacement search on 2016 GMC Trucks. A Canyon owner, for example, is looking at an entirely different size family than a Yukon owner, even though both wear GMC badges. Confirming the exact model first will narrow the search quickly and prevent confusion between crossover, light-duty truck, and heavy-duty truck fitments.

2016 GMC Trucks products in the sizes with current coverage use either raised white letters or raised black letters. 265/70R16, 255/65R17, 265/70R17, and 245/75R17 appear with RWL sidewalls, while 235/80R17 and 225/65R17 appear with RBL sidewalls. All of them are radial truck tires, but the sidewall appearance changes the visual character of the vehicle, especially on Sierra and Canyon applications.

For many owners, sidewall choice is partly aesthetic and partly tied to how the truck or SUV is being presented. Raised white letters suit a more traditional all-terrain look that fits many modern truck builds, while raised black letters give a more understated appearance. On a 2016 GMC Trucks vehicle, matching the sidewall style to the vehicle's overall look often matters as much as matching the size itself.

BFGoodrich covers the 2016 GMC Trucks sizes that currently have product coverage here. The brand appears in 265/70R16, 255/65R17, 265/70R17, 245/75R17, 235/80R17, and 225/65R17, all within the All-Terrain T/A KO2 family. Those applications lean toward truck and SUV use, especially Canyon and the Sierra HD models.

That concentration around one brand and one all-terrain series makes product selection more about matching the exact size, load need, and sidewall appearance than sorting through a wide brand field. A 2016 GMC Trucks owner should compare the sidewall marking carefully, particularly in 265/70R17 where more than one load-capacity version exists under the same basic size code.

The two 265/70R17 choices for 2016 GMC Trucks are both BFGoodrich All-Terrain T/A KO2 radials with RWL sidewalls and an S speed rating, but they differ in load capacity, inflation, and weight. One carries 2,470 pounds at 50 psi and weighs 45.7 pounds, while the other carries 3,195 pounds at 80 psi and weighs 53.5 pounds. Both fit 17-inch rims in the 7.0 to 9.0-inch width range.

That difference makes the sidewall service description more important than the basic size alone. A 2016 GMC Trucks Sierra 1500 owner who tows, hauls, or wants a heavier-duty tire should not assume every 265/70R17 is the same. Matching the tire's load capability to how the truck is used is the practical next step once the size itself has been confirmed.

Several 2016 GMC Trucks sizes have defined rim-width ranges. 265/70R16 fits 7.0 to 8.5-inch rims, 255/65R17 and 265/70R17 fit 7.0 to 9.0-inch rims, 245/75R17 fits 6.5 to 7.5-inch rims, and 235/80R17 and 225/65R17 fit 6.0 to 7.5 inches and 6.0 to 8.0 inches respectively. Those ranges are tied to the exact size, not to GMC as a whole.

That matters because a tire may share the same wheel diameter as another GMC fitment while still preferring a different wheel width. Before mounting replacement tires on a 2016 GMC Trucks vehicle, compare the wheel's actual width to the approved range for the chosen size. That check is especially useful on used trucks or SUVs that may no longer have their original wheels.

The 2016 GMC Trucks products with clear tire construction details are tubeless radials. That includes 265/70R16, 255/65R17, 265/70R17, 245/75R17, 235/80R17, and 225/65R17, all of which use modern tubeless construction rather than tube-type casing design. None of those covered sizes call for the tube-style markings commonly seen on earlier vintage applications.

Even with tubeless tires, the wheel and valve stem still deserve attention. A 2016 GMC Trucks owner should inspect the valve stem condition and confirm the wheel bead seats are clean and in good shape, especially on trucks that have seen off-road use or corrosion. Proper sealing hardware matters just as much as the tire itself when you want stable air retention.

A 2016 GMC Trucks vehicle should be stored away from direct sunlight, standing moisture, and ozone sources such as electric motors, battery chargers, welders, or compressors. Keeping the tires clean and properly inflated helps preserve their shape during periods of inactivity. Because every fitment here is radial, storage flat-spotting tends to be less pronounced than with older bias-ply tires, but long static periods still deserve attention.

Moving the vehicle periodically or shifting its contact patch can help reduce temporary flat spotting and keep the carcass from sitting under one load point for too long. If the vehicle will remain parked for an extended season, many collectors use stands or cradles to reduce stress on the tires. A dry, enclosed environment will do more for long-term tire condition than occasional cosmetic cleaning.

On a 2016 GMC Trucks vehicle, tire age is usually more important than mileage once the vehicle becomes a low-use truck or SUV. A practical rule is to begin evaluating tires closely around five to seven years from manufacture and to consider replacement around the ten-year mark regardless of remaining tread. The DOT date code on the sidewall is the best starting point for determining age.

That timeline matters because many GMC trucks and SUVs accumulate miles slowly, especially second vehicles, tow rigs, or collector-kept examples. A tire can still look usable at a glance while aging internally from time, heat cycles, and environmental exposure. Checking age alongside visible condition gives a more realistic picture than tread depth alone when planning service on a 2016 GMC Trucks vehicle.

Tires on a 2016 GMC Trucks vehicle should be inspected before every drive and again before any longer trip. Check air pressure, tread wear, sidewall cracking, punctures, bulges, and any signs of impact damage from curbs or road debris. Since the covered products are tubeless, the valve stems and bead area are also worth watching for leakage or age-related deterioration.

A quick walkaround can prevent a short local drive from turning into a roadside problem, especially on heavier models such as Sierra 2500 HD and Sierra 3500 HD that place greater demands on tires under load. Longer drives deserve a more deliberate check, including the spare if one is carried. Regular inspection is inexpensive insurance on a vehicle that may alternate between long storage and hard use.

The covered 2016 GMC Trucks products use radial construction and carry S speed ratings, which correspond to a maximum speed capability of 112 mph. That is well above normal U.S. highway travel, so the tire's basic speed rating is not usually the limiting factor in ordinary road use. On heavy-duty GMC trucks in particular, load condition, inflation, suspension condition, and braking system health often matter more in real-world driving.

Safe highway use still depends on choosing the correct size and enough load capacity for the specific vehicle. A 2016 GMC Trucks Sierra towing or hauling should be matched to the right load-rated tire, not just the right diameter and width. Condition also matters: age, pressure, damage, and uneven wear can turn a capable highway tire into a risky one regardless of its original rating.

Inflation pressure on 2016 GMC Trucks tires depends on the exact size and product. Among the covered sizes, 265/70R16, 245/75R17, and one 265/70R17 version carry 3,195 pounds at 80 psi; 235/80R17 carries 3,085 pounds at 80 psi; 255/65R17 and 225/65R17 carry 2,600 pounds at 65 psi and 2,150 pounds at 65 psi; and the lighter 265/70R17 version carries 2,470 pounds at 50 psi.

Those figures are the tire's rated capacities at maximum stated pressure, not a universal recommendation for every 2016 GMC Trucks application. The vehicle placard or owner's manual remains the right starting point for everyday use, with the tire manufacturer's rating used to understand the tire's upper capacity. Never transfer one pressure figure from a different GMC size just because the wheel diameter looks similar.

Before a longer drive in a 2016 GMC Trucks vehicle, inspect the tires for cracking, cuts, punctures, bulges, uneven wear, and proper cold inflation pressure. Look at the valve stems, confirm the tread is wearing evenly across the axle, and check the spare's condition and pressure if the vehicle carries one. On larger GMC trucks and SUVs, also consider whether the planned load matches the tire's capability.

Tires are only one part of the equation on a trip-ready 2016 GMC Trucks vehicle, but they are the part touching the road the entire time. A careful pre-drive inspection works best alongside checks of brakes, steering, suspension, and wheel fasteners. Spending a few minutes on those basics can make a long drive in a Yukon, Canyon, or Sierra far more predictable and less stressful.
