2020 Chevrolet Trucks Tire Fitment Guide

2020 Chevrolet Trucks vehicles use 27 sizes across 10 models: 235/65R18, 235/55R20, 265/45R21, 265/70R16, 255/55R20, 255/65R17, 265/60R18, 265/65R17, 225/65R17, 235/50R19, 225/60R18, 275/50R22, 275/60R20, 275/65R18, 255/70R17, 265/65R18, 265/70R17, 275/65R20, 245/75R17, 275/70R18, 235/80R17, 275/55R20, 285/45R22, 265/60R17, 255/65R18, 205/70R16, and 215/55R18. These fitments span 16- through 22-inch wheels and are divided among Blazer, Colorado, Equinox, Silverado 1500, Silverado 2500 HD, Silverado 3500 HD, Suburban, Tahoe, Traverse, and Trax applications.

That means there is no single tire size for all 2020 Chevrolet Trucks models. A buyer should start with the exact model name and existing wheel diameter, then narrow to the size that matches that specific package. Where product-level rim-width guidance exists, examples include 7.0 to 8.5 inches for 265/70R16, 7.0 to 9.0 inches for 255/65R17 and 265/70R17, 7.5 to 9.5 inches for 275/65R18 and 275/65R20, 6.5 to 7.5 inches for 245/75R17, 7.0 to 9.0 inches for 275/70R18, and 6.0 to 7.5 inches for 235/80R17.

On a 2020 Chevrolet Trucks tire, 265/70R17 is a metric radial code. The 265 is the nominal section width in millimeters, 70 is the aspect ratio, R identifies radial construction, and 17 is the wheel diameter in inches. Within the Chevrolet lineup, this size appears on the Silverado 1500, Silverado 2500 HD, and Tahoe.

Knowing how to read the code helps separate true fitment from visual similarity. A 265/70R17 tire may look close to another 17-inch truck size, but the width, sidewall height, and load version can still differ. In this case, available examples also differ in load capacity, from 2,470 pounds at 50 psi to 3,195 pounds at 80 psi, so matching both size and service range matters when the same code appears on light-duty and heavy-duty Chevrolet applications.

No. 2020 Chevrolet Trucks spans compact crossovers, midsize pickups, full-size SUVs, and heavy-duty trucks, so tire size changes significantly across the range. Some sizes are exclusive to one model, such as 235/65R18 on the Blazer or 235/80R17 on the Silverado 3500 HD, while others are shared by a few models, such as 255/55R20 on Colorado and Traverse or 265/65R18 on Silverado 1500, Suburban, and Tahoe.

That variation means year and make alone are not enough. The practical approach is to confirm the model first, then the wheel diameter, and then the exact size on the vehicle now. This is especially important on Tahoe, Silverado 1500, and Colorado, where multiple factory wheel packages exist and can point to very different tire dimensions even within the same model year.

Available sidewall styles for 2020 Chevrolet Trucks tires include both RWL and RBL, depending on size. RWL appears on sizes such as 265/70R16, 255/65R17, 275/65R18, 265/70R17, 245/75R17, and 275/70R18, while RBL appears on 225/65R17, 275/65R20, and 235/80R17. All of these are radial truck-oriented applications rather than vintage bias-ply offerings.

Sidewall appearance matters most when you want the tire to match the visual character of the vehicle. A raised white letter sidewall tends to emphasize an off-road or sport-truck look, while a raised black letter sidewall reads more understated. For a 2020 Chevrolet Trucks owner, the right choice usually comes down to matching the existing appearance of the vehicle and selecting the exact sidewall style offered in the correct size.

BFGoodrich is represented for several 2020 Chevrolet Trucks sizes, particularly truck and heavy-duty applications such as 265/70R16, 255/65R17, 225/65R17, 275/65R18, 265/70R17, 275/65R20, 245/75R17, 275/70R18, and 235/80R17. The products shown here center on the All-Terrain T/A KO2 series, which is a radial light-truck tire with a recognizable all-terrain profile.

That concentration in one brand does not make every Chevrolet model interchangeable. It simply means certain Colorado, Silverado, Tahoe, and Equinox sizes have a truck-focused BFGoodrich option in the correct dimensions. The best way to use that information is to confirm whether your Chevrolet falls into one of those supported sizes, then compare load capacity, rim-width range, and sidewall style before choosing a specific tire.

The two 265/70R17 tires for 2020 Chevrolet 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 important difference is service range: one version carries a maximum load of 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.

That difference matters because the same size code appears on Silverado 1500, Silverado 2500 HD, and Tahoe applications. A Tahoe or lighter-duty truck may not need the heavier load-range version, while a heavy-duty use case may. The safest approach is to match the new tire's service description to the vehicle's door-jamb tire information and intended use rather than selecting only by the 265/70R17 size marking.

Rim-width guidance for 2020 Chevrolet Trucks varies by size. Examples include 7.0 to 8.5 inches for 265/70R16, 7.0 to 9.0 inches for 255/65R17, 7.5 to 9.5 inches for 275/65R18, 7.0 to 9.0 inches for both versions of 265/70R17, 7.5 to 9.5 inches for 275/65R20, 6.5 to 7.5 inches for 245/75R17, 7.0 to 9.0 inches for 275/70R18, and 6.0 to 7.5 inches for 235/80R17. Even tires sharing the same rim diameter do not always use the same wheel-width range.

That is why wheel diameter alone is not a complete fitment check. Before mounting a replacement tire, confirm the actual wheel width on the vehicle and compare it to the range for the exact size you intend to run. This becomes especially important on Silverado and Colorado applications, where several 17- and 18-inch sizes exist but are not interchangeable just because the wheel diameter matches.

The radial Chevrolet truck sizes represented here do not carry tube-type markings in their size descriptions, and the available products are modern radial truck tires rather than classic tube-type constructions. Sizes such as 265/70R16, 255/65R17, 275/65R18, 265/70R17, 275/65R20, 245/75R17, 275/70R18, and 235/80R17 are presented without TT markings, which points buyers toward tubeless-style modern fitments.

Even so, the wheel still has to be suitable for tubeless use, especially if the vehicle has had aftermarket wheel changes or sees heavy service. If there is any doubt, inspect the wheel condition, valve stem setup, and wheel specification before mounting the tire. That extra step matters more on trucks that may tow, haul, or run at higher inflation pressures than on lighter crossover applications.

A 2020 Chevrolet Trucks vehicle should be stored clean, dry, and out of direct sunlight, with the tires protected from ozone sources such as electric motors, battery chargers, welders, and furnace equipment. Keep the tires at proper inflation, avoid parking on damp soil, and move the vehicle periodically if it will sit for long intervals. Radial tires generally tolerate storage better than older bias-ply designs, but long static periods can still create temporary flat-spotting and accelerate age-related cracking if conditions are poor.

For seasonal or collector-style use, a cool enclosed garage is far better than outdoor storage under a cover. If the truck or SUV will remain parked for months, some owners use tire cradles or stands to reduce stress at one contact patch. The goal is simple: limit heat, UV exposure, ozone, and long-term compression so the tires remain round, pliable, and ready for safe road use when the vehicle comes back out.

Tires on a 2020 Chevrolet Trucks vehicle should be judged by age as much as by tread depth. A common collector and enthusiast guideline is to begin evaluating tires closely once they reach roughly five to seven years of age, and to treat about ten years from the DOT date code as a serious replacement point even if the tread still looks serviceable. That matters because many trucks and SUVs accumulate low mileage while still aging in storage.

Mileage can be misleading on vehicles used for occasional towing, family trips, or seasonal duty. A tire that looks barely worn may still have hardened rubber, small sidewall cracks, or internal age-related fatigue. Check the DOT date code on each tire, inspect for weathering, and consider how the vehicle is used. A highway-driven Tahoe and a lightly used work-truck spare should both be evaluated by age, not just appearance.

Tires on a 2020 Chevrolet Trucks vehicle deserve a quick inspection before every drive and a more thorough inspection before any extended highway trip, towing job, or load-carrying use. Look for sidewall cracking, cuts, bulges, irregular tread wear, embedded objects, and pressure loss. On heavier Silverado applications, also pay close attention to uneven wear that could point to alignment, suspension, or inflation issues under load.

Routine checks matter because many problems show up visually before they become a roadside failure. Use a pressure gauge when the tires are cold, inspect valve stems, and do not forget the spare. If the truck or SUV spends long periods parked, make inspection part of the recommissioning routine before it returns to service. That habit is far more valuable than waiting for visible tread wear alone to tell the story.

Yes, the radial truck tires represented for 2020 Chevrolet Trucks are suitable for highway use when they are in good condition, correctly inflated, and matched to the vehicle's intended load. Speed ratings shown here include S, which carries a 112 mph ceiling, and R, which carries a 106 mph ceiling. Those limits are well above normal U.S. highway speeds, but they still need to be respected along with the tire's load rating.

In real-world use, overall vehicle condition often becomes the bigger variable than the speed symbol alone. A heavily loaded Silverado HD, for example, asks more of the tire than an unloaded commuter crossover. Safe highway driving depends on matching the tire to the application, maintaining inflation, and making sure the suspension, brakes, and alignment are all in proper condition before expecting stable long-distance behavior.

Inflation pressure on 2020 Chevrolet Trucks tires depends on the exact size, service range, and vehicle application. Available examples include 265/70R16 at 80 psi for 3,195 pounds, 255/65R17 at 65 psi for 2,600 pounds, 275/65R18 at 80 psi for 3,415 pounds, 265/70R17 at either 50 psi for 2,470 pounds or 80 psi for 3,195 pounds, 275/65R20 at 80 psi for 3,750 pounds, 245/75R17 at 80 psi for 3,195 pounds, 275/70R18 at 80 psi for 3,640 pounds, and 235/80R17 at 80 psi for 3,085 pounds.

Those figures are tire ratings, not a one-pressure-fits-all recommendation for every Chevrolet truck or SUV. For day-to-day use, start with the vehicle placard or owner's manual, then confirm that the tire you select supports the vehicle's required load at that pressure. Never transfer an 80 psi heavy-duty truck number onto a crossover or half-ton application simply because the rim diameter or brand name seems similar.

Before a longer drive in a 2020 Chevrolet Trucks vehicle, inspect all four tires and the spare for cracking, cuts, punctures, bulges, irregular wear, and cold inflation pressure. Confirm that the size on the vehicle matches the intended application, especially on models such as Tahoe, Colorado, and Silverado 1500 that used multiple wheel packages. If the vehicle will tow or carry a heavy load, verify that the tire's service range is appropriate for that use.

Tire readiness is only one part of the pre-trip picture, but it is a critical one. Longer drives generate sustained heat, and heat quickly exposes underinflation, aging rubber, and marginal load capacity. Once the tires check out, treat the rest of the vehicle with the same discipline by reviewing brakes, fluids, suspension, lights, and roadside equipment. That broader inspection is especially worthwhile on SUVs and trucks used intermittently.
