2021 Chevrolet Trucks Tire Fitment Guide
2021 Chevrolet Trucks covered an unusually broad range, from compact crossovers and midsize pickups to full-size SUVs and heavy-duty work trucks. That spread means tire sizing for 2021 Chevrolet Trucks is not a one-size-fits-all question, because the year includes everything from 16-inch crossover fitments to 22-inch full-size truck and SUV applications. Across 11 models, 28 distinct tire sizes appear, with some shared among closely related models such as Silverado 1500, Suburban, and Tahoe, while many others are model-specific. The first thing to confirm is your exact model, then the original tire size and wheel diameter, since that determines which fitments and product types apply.
Which Tire Size Is Right for Your 2021 Chevrolet Trucks
2021 Chevrolet Trucks uses 28 different tire sizes, and they vary significantly by model rather than carrying across the whole lineup. The real decision starts with confirming the correct model and wheel diameter, since crossover, SUV, light-duty pickup, and heavy-duty truck applications do not share the same fitment. Understanding those differences before choosing a product saves time and helps match the right tire to the right Chevrolet truck or SUV.

Eleven 2021 Chevrolet Trucks models are covered here, ranging from compact utility vehicles to heavy-duty pickups. Tire size varies by model, and in many cases by wheel package within the same model, so identifying the exact Chevrolet nameplate is the first step before comparing products. Select a model below to narrow the fitment history and see the tires that match its specific sizes.
2021 Chevrolet Trucks Blazer
The 2021 Blazer was Chevrolet's sporty midsize crossover, positioned with a more aggressive design than the family-focused utility models around it. Its fitments span 18-, 20-, and 21-inch wheels, so wheel diameter matters immediately before choosing a tire. The larger wheel packages especially make it important to confirm the exact OE size on the vehicle.
Associated Tire Sizes:
- 235/65R18 — radial, original 18-inch fitment
- 235/55R20 — radial, original 20-inch fitment
- 265/45R21 — radial, original 21-inch fitment
2021 Chevrolet Trucks Colorado
The 2021 Colorado filled Chevrolet's midsize pickup role, balancing everyday drivability with genuine truck capability. Its tires mount on 17- or 18-inch wheels depending on the application, with two distinct 17-inch sizes and one 18-inch size. That makes wheel diameter and the exact size on the truck more important than year and make alone.
Associated Tire Sizes:
- 255/65R17 — radial, truck-oriented 17-inch fitment
- 265/60R18 — radial, original 18-inch fitment
- 265/65R17 — radial, wider 17-inch fitment
2021 Chevrolet Trucks Equinox
The 2021 Equinox was Chevrolet's core compact crossover, aimed at everyday use with a wide range of wheel packages. Its tire applications cover 17-, 18-, and 19-inch wheels, so the correct fitment depends on the exact wheel package rather than the Equinox name alone. Buyers should verify the mounted size before choosing a replacement.
Associated Tire Sizes:
- 225/65R17 — radial, original 17-inch fitment
- 235/50R19 — radial, original 19-inch fitment

2021 Chevrolet Trucks Silverado 1500
The 2021 Silverado 1500 was Chevrolet's full-size light-duty pickup, offered across a broad range of trim and wheel combinations. Its fitments span 17-, 18-, 20-, and 22-inch wheels, and it also shares certain sizes with the Tahoe and Suburban while keeping several half-ton-only applications. That makes the exact wheel and tire size especially important before narrowing to a specific product.
Associated Tire Sizes:
- 275/60R20 — radial, shared full-size fitment

2021 Chevrolet Trucks Silverado 2500 HD
The 2021 Silverado 2500 HD was built for heavier payload and towing work than the half-ton Silverado, and its tire sizing reflects that heavier-duty mission. Its tires mount on 17-, 18-, and 20-inch wheels, with some sizes shared with the Silverado 1500 or 3500 HD and others unique to the 2500 HD. Load-oriented fitment details matter here just as much as wheel diameter.
Associated Tire Sizes:
- 275/65R20 — radial, heavy-duty 20-inch fitment
- 245/75R17 — radial, narrower heavy-duty 17-inch fitment

2021 Chevrolet Trucks Silverado 3500 HD
The 2021 Silverado 3500 HD sat at the top of Chevrolet's pickup hierarchy, aimed at serious towing and chassis load demands. Its applications use 17-, 18-, and 20-inch wheels, with some fitments shared with the 2500 HD and one size unique to the one-ton truck. Confirming the exact wheel diameter and OE size is essential before comparing heavy-duty tire options.

2021 Chevrolet Trucks Suburban
The 2021 Suburban remained Chevrolet's long-wheelbase full-size SUV, valued for passenger room and cargo capacity while sharing much of its platform with the Tahoe. Its fitments use 18-, 20-, and 22-inch wheels, and each size is shared with other full-size Chevrolet models rather than being Suburban-only. The practical question is which wheel package your Suburban has, not whether the model sits alone in the lineup.
Associated Tire Sizes:
- 275/50R22 — radial, shared 22-inch full-size fitment
- 265/65R18 — radial, shared 18-inch full-size fitment
- 275/60R20 — radial, shared 20-inch full-size fitment
2021 Chevrolet Trucks Tahoe
The 2021 Tahoe was Chevrolet's full-size SUV with a shorter overall body than the Suburban but closely related under the skin. It uses 18-, 20-, and 22-inch wheel applications, sharing several sizes with the Suburban and Silverado 1500 while also carrying one Tahoe-specific 20-inch fitment. Buyers should verify the exact mounted size because more than one 20-inch option appears within the Tahoe range.

- 275/50R22 — radial, shared 22-inch full-size fitment

2021 Chevrolet Trucks Trailblazer
The 2021 Trailblazer was Chevrolet's compact crossover, positioned below the Equinox and aimed at urban use with distinctive styling. Its fitments cover 16-, 17-, and 18-inch wheels, and the 16-inch size has the broadest sidewall-style choice among the available products. That makes the Trailblazer one of the more appearance-sensitive selections in the 2021 Chevrolet Trucks range.
Associated Tire Sizes:
- 225/60R17 — radial, narrow whitewall option available
- 215/65R16 — radial, blackwall, redline, or wide whitewall
- 225/55R18 — radial, original 18-inch fitment
2021 Chevrolet Trucks Traverse
The 2021 Traverse served as Chevrolet's larger three-row crossover, focused on family and travel duty rather than pickup-style work use. Its tires mount on either 18- or 20-inch wheels, so the choice begins with confirming wheel diameter rather than comparing multiple constructions. Once that is settled, the correct fitment path becomes straightforward.

Its applications use either 16- or 18-inch wheels, with one size tied to each wheel diameter. That makes quick visual confirmation of the wheel package an easy first step before choosing tires.
