2013 GMC Trucks Tire Fitment Guide

2013 GMC Trucks vehicles use 16 tire sizes across 8 models: 255/55R20, 255/65R18, and 255/60R19 for Acadia; 275/55R20, 265/65R18, 245/70R17, and 265/70R17 for Sierra 1500; 265/60R20, 265/70R18, 245/75R17, and 265/70R17 for Sierra 2500 HD; 265/60R20, 265/70R18, and 235/80R17 for Sierra 3500 HD; 235/55R18, 235/55R19, and 235/60R17 for Terrain; 275/55R20, 285/45R22, 285/50R20, 265/65R18, and 265/70R17 for Yukon; 275/55R20, 285/45R22, 285/50R20, and 265/70R17 for Yukon XL 1500; and 265/70R17 for Yukon XL 2500.

Rim diameters span 17, 18, 19, 20, and 22 inches, so year and make alone are not enough to choose a tire for 2013 GMC Trucks. If you are working with one of the 17-inch sizes that has product coverage here, rim width ranges are 6.5 to 8.0 inches for 245/70R17, 7.0 to 9.0 inches for 265/70R17, 6.5 to 7.5 inches for 245/75R17, and 6.0 to 7.5 inches for 235/80R17. Confirm the exact model and wheel diameter before narrowing the size.

On a 2013 GMC Trucks tire, 265/70R17 is a metric radial size. The 265 is the nominal section width in millimeters, 70 is the aspect ratio, the R identifies radial construction, and 17 is the wheel diameter in inches. This size appears across Sierra 1500, Sierra 2500 HD, Yukon, Yukon XL 1500, and Yukon XL 2500, making it one of the most widely shared sizes in the 2013 GMC Trucks range.

Understanding the code helps separate wheel fitment from load requirement. Two 265/70R17 BFGoodrich KO2 versions are available, both with an S speed rating up to 112 mph, but one is a 112S version rated at 2,470 pounds at 50 psi and the other is a 121S version rated at 3,195 pounds at 80 psi. That means the size code alone does not tell the whole story for heavier applications, so load index matters just as much as dimensions.

No, 2013 GMC Trucks models do not use the same tire size. The lineup includes compact and midsize crossovers, full-size SUVs, a light-duty pickup, and heavy-duty pickups, so sizes are spread across 17-, 18-, 19-, 20-, and 22-inch wheels. Some sizes overlap between related truck and SUV models, such as 265/70R17 and 275/55R20, but many sizes are unique to a single model family.

That variation means the first identification step is the model, not just the badge and model year. A Yukon may share certain sizes with a Sierra 1500, while a Sierra 3500 HD uses its own narrower heavy-duty 235/80R17 option, and Acadia and Terrain use crossover-specific fitments. If the truck or SUV has changed wheels over time, verifying the actual sidewall size on the vehicle is the safest starting point before choosing a replacement.

Sidewall styles for 2013 GMC Trucks tires vary by size in the available 17-inch coverage here. 245/70R17, 265/70R17, and 245/75R17 are offered with RWL sidewalls, while 235/80R17 appears with an RBL sidewall. Those styles matter mostly for appearance, since both are radial all-terrain truck tires, but they can change the visual character of the truck or SUV.

For a 2013 GMC Trucks owner, sidewall style is usually more about look than strict authenticity, since these are modern vehicles rather than concours-era restorations. An RWL sidewall tends to give a more classic light-truck appearance, while an RBL sidewall is visually quieter and more understated. If appearance matters as much as size, compare the sidewall marking on the current set or decide whether you want a more period truck look or a cleaner blackwall presentation.

BFGoodrich is the brand represented in the available product coverage for 2013 GMC Trucks here, specifically through the All-Terrain T/A KO2 series in 245/70R17, 265/70R17, 245/75R17, and 235/80R17. Those fitments center on truck and heavy-duty applications rather than crossover sizes. The KO2 is a well-known all-terrain radial, so the brand presence here leans toward utility-oriented use.

That matters most for Sierra and Yukon-family owners who want an all-terrain style tire in one of the covered 17-inch sizes. Acadia, Terrain, and several 18-, 19-, 20-, and 22-inch GMC applications fall outside the available product coverage shown here, so the buying decision on this page is really concentrated around truck-oriented 17-inch replacements. Once the size is confirmed, compare load index, sidewall style, and intended use rather than choosing by brand name alone.

The two 265/70R17 options for 2013 GMC Trucks are both BFGoodrich All-Terrain T/A KO2 radials with RWL sidewalls and an S speed rating, which carries a 112 mph ceiling. The key differences are load capacity and operating pressure: one version is 112S at 2,470 pounds at 50 psi and weighs 45.7 pounds, while the other is 121S at 3,195 pounds at 80 psi and weighs 53.5 pounds. Both mount on rims from 7.0 to 9.0 inches wide.

That makes the choice less about overall diameter and more about how the 2013 GMC Trucks application will be used. A lighter-duty fitment may align with the lower-load version, while heavier truck or carrying demands may call for the higher-load 121S tire. Matching the load index to the original requirement on the door placard and the vehicle's intended use is more important than assuming any 265/70R17 will serve the same role.

For the 2013 GMC Trucks sizes with product coverage here, rim width depends on the exact tire size. 245/70R17 fits rims from 6.5 to 8.0 inches wide, 265/70R17 fits 7.0 to 9.0 inches, 245/75R17 fits 6.5 to 7.5 inches, and 235/80R17 fits 6.0 to 7.5 inches. Each of those sizes uses a 17-inch rim diameter, but the acceptable rim-width spread is not identical from one size to another.

That means a 17-inch wheel is only part of the fitment picture for 2013 GMC Trucks. If a vehicle has aftermarket wheels or a wheel swap from another GMC or Chevrolet truck, verify both diameter and width before choosing a tire. Staying within the tire's approved rim-width range helps preserve sidewall shape, inflation behavior, and load-carrying characteristics, especially on Sierra HD and Yukon XL applications.

The available 2013 GMC Trucks products here are modern radial light-truck tires, and their size markings do not indicate tube-type construction. That points to tubeless use for the covered 17-inch applications rather than a tube-required setup. Tube fitment is not part of the normal replacement path for these BFGoodrich KO2 sizes when they are mounted on appropriate tubeless wheels.

The practical check is the wheel itself. If a 2013 GMC Trucks wheel is original and in sound condition, tubeless radial service is the expectation for these sizes, but any repaired, heavily corroded, or non-original wheel should be inspected before mounting. On a modern GMC truck or SUV, sealing surface condition and valve-stem condition matter more than tube selection.

Original 2013 GMC Trucks wheels cannot be treated as interchangeable across all tire sizes in the lineup. GMC used 17-, 18-, 19-, 20-, and 22-inch wheel diameters across Acadia, Terrain, Sierra, and Yukon models, and even the trucks that share a 17-inch diameter may need different tire widths and load-capacity versions. Wheel diameter has to match the tire exactly.

A 17-inch Sierra or Yukon wheel may still need a closer look before moving from 245/70R17 to 265/70R17 or into a heavy-duty 245/75R17 or 235/80R17, because rim-width ranges differ by size. The safest approach is to confirm the wheel diameter cast or stamped on the wheel, check the current tire sidewall, and then compare that with the approved rim-width range for the tire you want to run.

A stored 2013 GMC Trucks should be kept out of direct sunlight, away from ozone sources such as electric motors or welders, and on a clean, dry surface. Inflate the tires to the vehicle maker's recommended cold pressure and move the vehicle periodically so one section of the tread is not carrying the load for months at a time. Because these are radial tires, long static storage is usually less prone to severe flat-spotting than old bias-ply construction, but it is still worth avoiding prolonged stationary loading.

That matters especially for Yukon, Sierra HD, and other heavier 2013 GMC Trucks models that place more weight on each tire during storage. If the vehicle will sit for an extended season, rolling it occasionally or supporting it in a way that reduces static load can help. Clean, stable storage conditions often do more for tire longevity than low annual mileage alone.

Tires on a 2013 GMC Trucks should be judged more by age, condition, and service history than by tread depth alone. A common collector-vehicle rule is to begin evaluating tires closely around five to seven years of age and to consider replacement as they approach ten years, even if mileage is low. The DOT date code on the sidewall is the clearest starting point for age.

That approach is especially useful on a 2013 GMC Trucks vehicle that may see seasonal use, towing duty, or long periods of storage. Full-size SUVs and heavy-duty pickups can still place real stress on an older tire with good-looking tread, particularly under load. If the tires are aging out, cracking, or hardening, replacement should take priority over trying to use up remaining tread.

Tires on a 2013 GMC Trucks should be inspected before every drive and especially before a longer highway trip. Look for sidewall cracking, uneven wear, punctures, cuts, bulges, and any sign that the tire is losing pressure. On truck and SUV applications, checking tread depth across the full width is important because alignment and load use can wear the shoulders or center differently.

A more detailed inspection every few months is a good habit, particularly on Sierra and Yukon models that may tow, carry weight, or sit for stretches between uses. Check cold pressures, inspect valve stems, and make sure the spare is still usable and inflated. Catching a damaged tire in the garage is far easier than discovering it after the vehicle is loaded for a trip.

The 2013 GMC Trucks Acadia was originally a radial-tire vehicle, not a bias-ply-era design, and its fitments here are 255/65R18, 255/60R19, and 255/55R20 depending on wheel package. That places the Acadia firmly in the modern metric-radial period, where aspect ratio and wheel diameter are integral parts of the original fitment rather than optional styling clues. The exact original size should be confirmed against the placard and the vehicle's wheel package.

For an owner aiming to keep a 2013 GMC Trucks Acadia factory-correct in appearance and behavior, matching the original size is usually more important than chasing a particular sidewall style. Modern vehicles like the Acadia are also more sensitive to overall tire dimensions, so downsizing or upsizing casually can affect the way the crossover sits and drives. Factory literature and marque-specific resources remain worthwhile if the vehicle has changed wheels at some point.

Correct tire fitment does matter when showing a 2013 GMC Trucks, even though these are newer vehicles than traditional concours-era classics. Judges and knowledgeable enthusiasts often notice whether the tire size matches the wheel package, whether the stance looks factory-appropriate, and whether the tire's sidewall style suits the truck or SUV's intended presentation. A mismatch in diameter or an obviously wrong load-class tire can stand out quickly.

That matters differently depending on the model. A Sierra HD shown as a preserved work-oriented truck should not wear a light-duty tire that visually or functionally understates its role, while a Yukon on factory-style large-diameter wheels benefits from the correct low-profile metric size. If the event has strict authenticity expectations, use factory references and GMC enthusiast communities to confirm what your specific model and wheel package should wear.

The two 265/70R17 options for the 2013 GMC Trucks share the same basic dimensions, brand, series, sidewall style, and S speed rating, so they look similar at a glance. Their main differences are in load index, pressure, and weight: one is 112S at 2,470 pounds at 50 psi and 45.7 pounds, while the other is 121S at 3,195 pounds at 80 psi and 53.5 pounds. Both fit 7.0- to 9.0-inch rims.

For authenticity-minded owners, the more appropriate choice is the one that aligns with the original duty class of the 2013 GMC Trucks model rather than simply matching the sidewall size. A Sierra 2500 HD or Yukon XL 2500 may call for a more robust version than a lighter-duty application that also uses 265/70R17. Matching the intended load role preserves both the appearance and the engineering logic of the original vehicle.

2013 GMC Trucks tires can be appropriate for highway driving when the correct size, load index, and condition are matched to the vehicle. The covered 17-inch BFGoodrich KO2 products carry an S speed rating, which means a 112 mph ceiling. That is comfortably above normal highway speeds, but the tire still has to be inflated correctly and chosen in the right load version for the truck or SUV.

On many 2013 GMC Trucks applications, the vehicle's weight, towing load, braking condition, suspension wear, and alignment matter more in real-world highway use than pure speed rating. A Sierra HD or Yukon XL used for towing can stress a tire much more than a lightly driven crossover. If the tires are aged, underinflated, or carrying the wrong load index, highway confidence drops quickly even when the tread looks acceptable.

Inflation pressure for 2013 GMC Trucks tires should start with the factory placard for the exact model and size, then be checked against the tire's own rating structure. The covered products here include 245/70R17 at 3,000 pounds maximum load at 80 psi, 265/70R17 at either 2,470 pounds at 50 psi or 3,195 pounds at 80 psi, 245/75R17 at 3,195 pounds at 80 psi, and 235/80R17 at 3,085 pounds at 80 psi. Those figures are maximum load-and-pressure ratings, not universal everyday inflation targets.

That distinction is important because a 2013 GMC Trucks Sierra 2500 HD and a Yukon using a 17-inch tire do not necessarily need the same cold pressure in normal service. The door placard remains the baseline for routine driving, while the tire manufacturer's maximum rating explains the tire's upper load capacity. Never transfer a pressure figure from one size to another or assume that a heavy-duty tire should automatically be run at its sidewall maximum in all conditions.

Before a longer drive in a 2013 GMC Trucks vehicle, inspect each tire for cracking, punctures, cuts, bulges, uneven wear, and proper cold inflation pressure. Check that the size on the vehicle matches the intended application, especially on models that commonly share wheel diameters but use different load-capacity versions. The spare tire should also be inspected and inflated, since an aged or neglected spare can turn a minor roadside issue into a trip-ending problem.

Tire checks are only one part of preparing a 2013 GMC Trucks vehicle for distance. Sierra and Yukon models, in particular, may also be used for towing, cargo hauling, or family travel, so brakes, steering, suspension, and wheel-bearing condition deserve attention before the trip. If the tires show age cracking or the load rating does not suit the planned use, it is better to correct that before departure than to test the margin on the road.
