The 2020 Chevrolet Trucks Silverado 2500 HD sits firmly in the modern heavy-duty pickup world, where towing, payload, and everyday truck use all place real demands on tire choice. This generation blends current heavy-duty capability with the broad trim spread that buyers expect, from work-focused configurations to more upscale versions. Tire fitment on the 2020 Chevrolet Trucks Silverado 2500 HD is entirely radial, but the exact size varies by sub-model and wheel package, with 17-inch, 18-inch, and 20-inch applications all in play. Available choices center on BFGoodrich All-Terrain T/A KO2 products with RWL or RBL sidewall presentation. The key step is matching the truck's exact sub-model and wheel diameter before comparing load-oriented product details.
Which Tire Size Is Right for The 2020 Chevrolet Trucks Silverado 2500 HD
The 2020 Chevrolet Trucks Silverado 2500 HD uses four primary tire sizes, and the correct one depends on the specific sub-model and wheel setup. Fitment varies across 17-inch, 18-inch, and 20-inch rims, so the first step is confirming the truck's actual wheel diameter before selecting a tire. Once that is clear, the decision shifts to the right metric radial size and the product specifications that suit how the truck is used.
275/65R20 is a metric radial size in which 275 identifies the section width in millimeters, 65 is the aspect ratio, R denotes radial construction, and 20 is the wheel diameter in inches. On the 2020 Chevrolet Trucks Silverado 2500 HD, this size serves trucks equipped with 20-inch wheels and keeps the fitment in a modern radial format suited to heavy-duty pickup use. Available options include the BFGoodrich All-Terrain T/A KO2 with an RBL sidewall treatment. This size is the one to evaluate when the truck has the larger factory-style wheel setup and you want to confirm load and rim-width compatibility carefully.
245/75R17 is a metric radial size with a 245-millimeter section width, a 75-series profile, radial construction, and a 17-inch rim diameter. On the 2020 Chevrolet Trucks Silverado 2500 HD, this size appears on certain 17-inch wheel applications and represents one of the narrower primary fitments used across the model range. The available BFGoodrich All-Terrain T/A KO2 version carries a raised white letter sidewall, giving it a more traditional truck-tire look. This is the size to consider when the truck uses a 17-inch wheel and the goal is staying with the proper diameter and profile for that setup.
265/70R17 is a metric radial tire size where 265 is the nominal section width in millimeters, 70 is the aspect ratio, R indicates radial construction, and 17 marks the rim diameter. For the 2020 Chevrolet Trucks Silverado 2500 HD, it is another 17-inch fitment, but it differs from 245/75R17 in width and product specification. BFGoodrich All-Terrain T/A KO2 options in this size use RWL sidewalls and are available with different load-capacity figures. This size deserves a close look when the truck already runs 17-inch wheels and the buyer needs to compare the specific tire version against the truck's intended duty.
275/70R18 is a metric radial size with a 275-millimeter section width, a 70-series profile, radial construction, and an 18-inch wheel diameter. On the 2020 Chevrolet Trucks Silverado 2500 HD, this size covers certain 18-inch applications and sits between the 17-inch and 20-inch fitments in wheel diameter. The available BFGoodrich All-Terrain T/A KO2 version uses a raised white letter sidewall and an all-terrain series format that suits truck use visually and functionally. This is the size to check when the truck is equipped with 18-inch wheels and the priority is matching that wheel package correctly.
2020 Chevrolet Trucks Silverado 2500 HD Sub-Model Tires
Sub-model fitment on the 2020 Chevrolet Trucks Silverado 2500 HD is not one-size-fits-all, because several trims use different tire sizes and wheel diameters. Checking the exact trim matters here, especially on LT, LTZ, and WT trucks where more than one primary size is possible.

2020 Chevrolet Trucks Silverado 2500 HD Custom
The 2020 Chevrolet Trucks Silverado 2500 HD Custom uses the 275/65R20 radial tire size. Tire selection here is straightforward once the 20-inch wheel setup is confirmed, and the focus shifts to the available all-terrain product details rather than sorting through multiple primary sizes.
2020 Chevrolet Trucks Silverado 2500 HD High Country
The 2020 Chevrolet Trucks Silverado 2500 HD High Country uses the 275/65R20 radial tire size. That makes wheel-diameter confirmation simple, with the main decision centered on choosing the right 20-inch tire specification for the truck's intended road and truck-use balance.
The 2020 Chevrolet Trucks Silverado 2500 HD LT can use 245/75R17, 265/70R17, 275/70R18, or 275/65R20 depending on its wheel setup. Tire selection starts with confirming the actual rim diameter on the truck, since LT fitment spans three wheel sizes and more than one 17-inch option.
The 2020 Chevrolet Trucks Silverado 2500 HD LTZ uses either 275/70R18 or 275/65R20 radial tires. The important step is verifying whether the truck carries 18-inch or 20-inch wheels before comparing tire details, sidewall presentation, and other product characteristics.
The 2020 Chevrolet Trucks Silverado 2500 HD WT uses 245/75R17, 265/70R17, or 275/70R18 depending on the truck's wheel package. Because WT fitment crosses both 17-inch and 18-inch applications, wheel diameter and the actual installed size should be confirmed before making a replacement choice.
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.
Best 2020 Chevrolet Trucks Silverado 2500 HD Tires for Sale

For the 2020 Chevrolet Trucks Silverado 2500 HD, the most important questions usually involve identifying the correct tire size by trim and wheel diameter, then comparing sidewall style, load-oriented specifications, and general fitment checks before the truck goes back on the road.
Tire Size & Fitment
What tire size fits a 2020 Chevrolet Trucks Silverado 2500 HD?
The 2020 Chevrolet Trucks Silverado 2500 HD uses four primary tire sizes: 245/75R17, 265/70R17, 275/70R18, and 275/65R20. All four are radial sizes, and the correct one depends on the truck's sub-model and wheel package rather than the model name alone.
The practical step is to confirm the exact trim and actual wheel diameter on the truck before choosing a replacement tire. LT, LTZ, and WT models can carry more than one primary size, so checking the wheel itself and the current tire placard helps avoid choosing the right style in the wrong diameter.
What size rim does a 2020 Chevrolet Trucks Silverado 2500 HD use?
A 2020 Chevrolet Trucks Silverado 2500 HD can use 17-inch, 18-inch, or 20-inch rims, depending on the sub-model and configuration. The primary tire sizes tied to those wheel diameters are 245/75R17 and 265/70R17 for 17-inch rims, 275/70R18 for 18-inch rims, and 275/65R20 for 20-inch rims.
Rim diameter is the first fitment check because a 17-inch tire cannot be mounted on an 18-inch or 20-inch wheel, even if the truck looks similar across trims. Wheel width also matters once the diameter is confirmed, especially on a heavy-duty pickup where load-capacity and proper tire support are important.
Why does the 2020 Chevrolet Trucks Silverado 2500 HD have more than one tire size?
More than one tire size appears on the 2020 Chevrolet Trucks Silverado 2500 HD because the model range covers several trims and wheel packages. Custom and High Country use 275/65R20, LT can use four different sizes, LTZ uses 275/70R18 or 275/65R20, and WT uses 245/75R17, 265/70R17, or 275/70R18.
That means replacement selection is not just a matter of buying any Silverado 2500 HD tire. Matching the exact sub-model helps, but the safest next check is the installed wheel diameter and current size marking, especially on trucks that may have had wheel changes or package swaps during their working life.
Choosing the Right Tire
What should I consider when choosing a tire for a 2020 Chevrolet Trucks Silverado 2500 HD?
Start with the correct primary size for the truck, then compare the tire's rim-diameter match, rim-width range, and load-related specifications. On the 2020 Chevrolet Trucks Silverado 2500 HD, that means selecting among 17-inch, 18-inch, or 20-inch radial sizes rather than treating all trims as identical.
After size is confirmed, think about how the truck is actually used. A Silverado 2500 HD that sees towing, hauling, or rougher surfaces may lead you to focus more closely on the exact tire version, while a more lightly used truck may place greater emphasis on wheel compatibility and sidewall appearance.
What sidewall styles are available for 2020 Chevrolet Trucks Silverado 2500 HD tires?
Sidewall appearance on available 2020 Chevrolet Trucks Silverado 2500 HD tires includes RWL and RBL styles. The 245/75R17, 265/70R17, and 275/70R18 BFGoodrich All-Terrain T/A KO2 options use RWL sidewalls, while the 275/65R20 BFGoodrich All-Terrain T/A KO2 uses an RBL sidewall.
That gives buyers a visual choice as well as a fitment choice. Sidewall style does not override the need to match the truck's correct size and wheel diameter, but once those are settled, it can help shape whether the finished look leans more toward a traditional raised-letter truck presentation or a more subdued sidewall treatment.
What tire series are available for the 2020 Chevrolet Trucks Silverado 2500 HD?
The available tire series for the 2020 Chevrolet Trucks Silverado 2500 HD is the BFGoodrich All-Terrain T/A KO2. It appears across all four primary sizes used on this truck, so the comparison is less about switching between series and more about choosing the right size and product specification within the same family.
That consistency can make selection simpler, but it does not eliminate the need to compare details carefully. Within the KO2 line, rim-width ranges, sidewall style, weight, and load-capacity figures still vary by size and by specific tire version, which matters on a heavy-duty truck expected to do real work.
Restoration & Appearance
Which tire should I choose for a period-style 2020 Chevrolet Trucks Silverado 2500 HD?
A period-style choice for a 2020 Chevrolet Trucks Silverado 2500 HD starts with keeping the truck in its correct original-size format for the actual trim and wheel package. Because this is a modern heavy-duty pickup, the period-style approach is less about vintage construction and more about preserving the proper radial size and wheel-diameter relationship.
Appearance then comes from the available sidewall treatment and the truck's intended presentation. An RWL all-terrain tire can give the Silverado a more assertive truck look, while an RBL presentation is more restrained, but either should still be chosen only after confirming the exact factory wheel size now on the truck.
Does correct tire fitment matter for a 2020 Chevrolet Trucks Silverado 2500 HD restoration?
Correct tire fitment matters on a 2020 Chevrolet Trucks Silverado 2500 HD restoration because the truck uses several primary sizes across different trims and wheel packages. Staying with the right diameter and size family helps preserve the truck's intended stance, wheel relationship, and overall presentation.
A restoration-minded buyer should verify what wheels belong on the specific truck before focusing on tread style or sidewall appearance. If exact originality matters, build records, sales literature, or marque-specific references can help confirm whether the truck should be on 17-inch, 18-inch, or 20-inch wheels before tire selection goes any further.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Chevrolet Trucks Silverado 2500 HD?
Yes, modifications can affect tire fitment on a 2020 Chevrolet Trucks Silverado 2500 HD. Aftermarket wheels, suspension changes, leveling kits, ride-height changes, or body alterations can all change the relationship between the tire, the wheel, and the available clearance at the fender and steering components.
A truck that has been altered should be checked by its actual wheel diameter, wheel width, and current tire size rather than by trim name alone. Clearance at full steering lock and under load is worth confirming as well, especially when the truck has moved away from its original wheel-and-tire package.
What should I inspect before driving a 2020 Chevrolet Trucks Silverado 2500 HD on new tires?
Before driving a 2020 Chevrolet Trucks Silverado 2500 HD on new tires, inspect the wheel condition, verify that the tire size matches the wheel diameter, and confirm that inflation is set appropriately for the tire being used. It also makes sense to check for rubbing points, valve condition, and secure mounting.
A heavy-duty pickup deserves an extra walkaround after installation and again after some initial road use. Look for any sign of uneven clearance, air loss, or abnormal wear, and pay attention to how the truck tracks and steers, especially if it is used for towing, hauling, or mixed on-road and off-road driving.
How often should tires on a 2020 Chevrolet Trucks Silverado 2500 HD be inspected?
Tires on a 2020 Chevrolet Trucks Silverado 2500 HD should be inspected regularly, not just when replacement time arrives. Frequent checks for tread wear, cuts, punctures, sidewall damage, and pressure loss are especially important on a heavy-duty truck that may carry loads or spend time on rougher surfaces.
Inspection should also become more deliberate before longer drives, towing trips, or seasonal use changes. Even when tread looks acceptable, uneven wear can point to alignment, suspension, or inflation issues, and catching those early helps protect both the tire and the truck's overall road manners.
