2020 Chevrolet Trucks Silverado 3500 HD Tires

The 2020 Chevrolet Trucks Silverado 3500 HD sits firmly in the modern heavy-duty pickup world, where towing, payload, and long-wheelbase stability matter just as much as everyday road manners. This generation brought a more substantial stance and a work-focused chassis, so tire selection is tied closely to the truck’s exact configuration. Depending on sub-model, the 2020 Chevrolet Trucks Silverado 3500 HD uses 235/80R17, 275/70R18, or 275/65R20 radial tires. Available choices here center on BFGoodrich All-Terrain T/A KO2 fitments, with RBL or RWL sidewall presentation depending on size. The key step is matching the truck’s sub-model and wheel diameter before comparing appearance, load-oriented specs, and road-use needs.

Which Tire Size Is Right for The 2020 Chevrolet Trucks Silverado 3500 HD

The 2020 Chevrolet Trucks Silverado 3500 HD uses three primary tire sizes, and the right one depends on the exact sub-model and wheel setup. All three are radial fitments, but they span 17-inch, 18-inch, and 20-inch rims, so confirming wheel diameter comes first. After that, the real decision is choosing the size that matches the truck’s configuration and then comparing sidewall style, rim-width range, and other product details within that fitment.

1
275/65R20Metric radial
Fit(s): High Country, LT, and LTZ
Construction: RadialRim: 20 in

A 275/65R20 tire is a metric radial size with a 275-millimeter nominal section width, a 65-series aspect ratio, and fitment for a 20-inch rim. On this Silverado 3500 HD application, it serves as one of the larger single-rear-wheel fitments and keeps the truck in a modern radial construction. In this size, the available BFGoodrich option comes from the All-Terrain T/A KO2 line with an RBL sidewall treatment. This is the size to evaluate when the truck is equipped with the matching 20-inch wheel package, especially if tire appearance and wheel compatibility both matter.

235/80R17Metric radial
Fit(s): High Country (DRW), LT (DRW), LTZ (DRW), and WT (DRW)
Construction: RadialRim: 17 in

A 235/80R17 tire uses a 235-millimeter nominal section width, an 80-series aspect ratio, and a 17-inch rim diameter. Within the Silverado 3500 HD range, this radial size is tied to dual-rear-wheel configurations rather than the larger single-rear-wheel setups. The available BFGoodrich All-Terrain T/A KO2 version uses an RBL sidewall and a narrower rim-width range than the larger sizes on this page. This fitment is the one to confirm when the truck has the correct 17-inch dually wheel arrangement and you want to stay with the intended size format for that configuration.

275/70R18Metric radial
Fit(s): LT, LTZ, and WT
Construction: RadialRim: 18 in

A 275/70R18 tire is a metric radial that combines a 275-millimeter nominal section width with a 70-series aspect ratio for an 18-inch rim. On the 2020 Chevrolet Trucks Silverado 3500 HD, this size appears on certain single-rear-wheel trims and shares the same basic width designation as the 20-inch option while using a different wheel diameter and profile. The available BFGoodrich All-Terrain T/A KO2 product in this size carries an RWL sidewall style. This size deserves close attention when the truck is equipped with 18-inch wheels and the goal is to keep the proper fitment for that specific configuration.

2020 Chevrolet Trucks Silverado 3500 HD Sub-Model Tires

Sub-model fitment on the 2020 Chevrolet Trucks Silverado 3500 HD is not one-size-fits-all. Tire choice depends on whether the truck is WT, LT, LTZ, or High Country, and just as importantly, whether it is a single-rear-wheel or DRW configuration.

1

2020 Chevrolet Trucks Silverado 3500 HD High Country

The High Country uses the 275/65R20 radial fitment, placing it with the 20-inch wheel configuration rather than the smaller-rim setups elsewhere in the range. Tire selection here centers on confirming that wheel diameter first, then comparing the available all-terrain product details and sidewall presentation within that size.

2020 Chevrolet Trucks Silverado 3500 HD High Country (DRW)

The High Country (DRW) moves to the 235/80R17 radial size, which separates it clearly from the single-rear-wheel High Country. That makes wheel and rear-axle configuration especially important before choosing tires, since the dually setup uses a different size and a different rim diameter.

2020 Chevrolet Trucks Silverado 3500 HD LT

The LT can use either 275/65R20 or 275/70R18, so this trim requires a direct check of the truck’s actual wheel diameter before selecting a tire. Once that is confirmed, the decision shifts to the product characteristics available in the matching size rather than guessing between two primary fitments.

2020 Chevrolet Trucks Silverado 3500 HD LT (DRW)

The LT (DRW) uses the 235/80R17 radial fitment associated with the dual-rear-wheel configuration. Tire selection should begin with confirming the 17-inch dually wheel setup, then move to load-oriented product details and fitment checks appropriate to that specific arrangement.

2020 Chevrolet Trucks Silverado 3500 HD LTZ

The LTZ shares the same two-size situation as the LT, using either 275/65R20 or 275/70R18 depending on wheel setup. That means the correct tire choice starts with the truck’s actual rim diameter, followed by a closer look at sidewall style and other product differences within the proper size.

2020 Chevrolet Trucks Silverado 3500 HD LTZ (DRW)

The LTZ (DRW) uses 235/80R17, keeping it aligned with the dually side of the Silverado 3500 HD range rather than the larger single-rear-wheel fitments. For this sub-model, proper tire selection depends on staying with the correct 17-inch DRW size and checking wheel compatibility carefully.

2020 Chevrolet Trucks Silverado 3500 HD WT

The WT uses 275/70R18, making its fitment more straightforward than the LT and LTZ trims that can appear with more than one primary size. Tire selection here is mostly about matching the 18-inch wheel setup and then choosing the available radial option in the proper configuration.

2020 Chevrolet Trucks Silverado 3500 HD WT (DRW)

The WT (DRW) uses the 235/80R17 radial size, which is distinct from the WT single-rear-wheel fitment. That difference makes it important to verify the truck’s DRW wheel arrangement before comparing tires, since the dually setup carries its own size and rim requirements.

Frequently Asked Questions

Owners of a 2020 Chevrolet Trucks Silverado 3500 HD usually need to sort out exact tire size by sub-model and wheel diameter first. The questions below focus on fitment, rim sizing, available tire choices, and the checks that matter before road use.

Tire Size & Fitment

What tire size fits a 2020 Chevrolet Trucks Silverado 3500 HD?

The 2020 Chevrolet Trucks Silverado 3500 HD uses three primary tire sizes: 235/80R17, 275/70R18, and 275/65R20. The correct size depends on the truck’s exact sub-model and whether it is a single-rear-wheel or DRW configuration, so there is not one universal size for every Silverado 3500 HD in this model year.

The practical first step is to confirm the truck’s actual wheel diameter and trim configuration before selecting a tire. LT and LTZ trucks can appear with either 18-inch or 20-inch fitments, while DRW models use 235/80R17, so checking the truck itself prevents choosing the right tire in the wrong size.

What size rim does a 2020 Chevrolet Trucks Silverado 3500 HD use?

Rim diameter on the 2020 Chevrolet Trucks Silverado 3500 HD depends on tire size. The 235/80R17 fitment uses a 17-inch rim, the 275/70R18 fitment uses an 18-inch rim, and the 275/65R20 fitment uses a 20-inch rim.

That makes wheel diameter the most important fitment check before comparing tires. A truck equipped with 18-inch wheels cannot use a 20-inch tire size, and a DRW setup using 17-inch tires should be matched carefully to the correct dually wheel arrangement, not just the overall tire width or tread style.

Why does the 2020 Chevrolet Trucks Silverado 3500 HD have more than one tire size?

The 2020 Chevrolet Trucks Silverado 3500 HD has more than one tire size because the lineup covers different trims and wheel configurations, including both single-rear-wheel and DRW versions. High Country, LT, LTZ, and WT do not all share the same wheel package, so tire size changes with the truck’s exact setup.

That means trim name alone is not always enough to choose a tire. LT and LTZ models can use either 275/70R18 or 275/65R20, while DRW versions move to 235/80R17, so the safest approach is to verify sub-model, rear-wheel configuration, and current wheel diameter together before making a selection.

Choosing the Right Tire

What should I consider when choosing a tire for a 2020 Chevrolet Trucks Silverado 3500 HD?

Start with the truck’s exact primary size: 235/80R17, 275/70R18, or 275/65R20. From there, compare radial construction details that matter to a heavy-duty pickup, including rim-width compatibility, maximum load capacity at the stated pressure, sidewall style, and whether the truck is a single-rear-wheel or DRW configuration.

A good choice for one Silverado 3500 HD may be wrong for another if the wheel diameter or rear-wheel setup differs. It also helps to think about how the truck is used, since towing, work duty, and general road driving all make proper sizing and load-oriented specification checks more important than appearance alone.

What sidewall styles are available for 2020 Chevrolet Trucks Silverado 3500 HD tires?

Sidewall style varies by size on this application. The available 275/65R20 and 235/80R17 tires use an RBL sidewall, while the available 275/70R18 tire uses an RWL sidewall, giving buyers a visible appearance difference even within the same BFGoodrich All-Terrain T/A KO2 series.

That detail matters if the truck’s visual presentation is part of the decision, especially on a larger modern pickup where sidewall appearance is easy to notice. Sidewall style should still come after confirming the correct tire size, since choosing an RWL or RBL look in the wrong rim diameter does not solve the actual fitment requirement.

What tire series are available for the 2020 Chevrolet Trucks Silverado 3500 HD?

The available tire series across these Silverado 3500 HD fitments is BFGoodrich All-Terrain T/A KO2. It appears in all three primary sizes on this page, so the comparison is less about switching between series and more about choosing the version that matches the truck’s wheel diameter and configuration.

Because the same series appears across multiple fitments, the selection process becomes more size-driven than brand- or line-driven. Once the correct 17-inch, 18-inch, or 20-inch fitment is established, details such as sidewall style, rim-width range, and stated load capacity become the meaningful differences to compare.

Restoration & Appearance

Does correct tire fitment matter for a 2020 Chevrolet Trucks Silverado 3500 HD restoration?

Yes, correct tire fitment still matters on a 2020 Chevrolet Trucks Silverado 3500 HD restoration or refurbishment, even though this is a late-model heavy-duty truck rather than a vintage collector car. The correct size helps preserve the truck’s intended stance, wheel relationship, and overall visual balance within its original-style configuration.

Appearance should be matched to the truck’s actual wheel setup instead of chosen in isolation. A proper-looking result starts with the right 17-inch, 18-inch, or 20-inch fitment for the specific sub-model, then moves to details like RBL or RWL sidewall treatment and a tire series that suits the build’s intended presentation.

How does tire construction affect the appearance of a restored 2020 Chevrolet Trucks Silverado 3500 HD?

On the 2020 Chevrolet Trucks Silverado 3500 HD, construction does not create a bias-ply versus radial appearance decision because the primary fitments here are all radial. The more noticeable visual differences come from the tire’s size, wheel diameter, and sidewall treatment, especially the contrast between RBL and RWL presentations.

That means a restoration-oriented or refurbishment-oriented build should focus on matching the truck’s original-style wheel setup first. Once the correct radial size is established, the remaining appearance choices are mostly about how the sidewall looks on the vehicle and whether the tire’s proportions suit the truck’s intended overall stance.

Fitment, Maintenance & Road Use

Can modifications affect tire fitment on a 2020 Chevrolet Trucks Silverado 3500 HD?

Yes, modifications can affect tire fitment on a 2020 Chevrolet Trucks Silverado 3500 HD. Aftermarket wheels, suspension changes, leveling kits, lift kits, or body changes can alter the wheel diameter, rim width, and available clearance, which matters on a truck that already uses more than one factory-size range across its sub-models.

Any truck that has been changed from its original wheel-and-tire setup should be checked carefully before replacement. It helps to confirm wheel diameter, current rim width, steering clearance, and fender or suspension clearance directly on the vehicle so the selected 17-inch, 18-inch, or 20-inch tire size matches the actual setup.

What should I inspect before driving a 2020 Chevrolet Trucks Silverado 3500 HD on new tires?

Before driving on new tires, check that the 2020 Chevrolet Trucks Silverado 3500 HD has the correct size for its sub-model, the proper wheel diameter, and adequate clearance at the front suspension, rear wheel area, and steering range. Tire pressure should also be set appropriately, and the wheels should be in sound condition.

A heavy-duty truck benefits from a quick follow-up inspection after initial road use as well. Looking for uneven wear, rubbing marks, abnormal vibration, or pressure loss can catch mounting or setup issues early, especially on trucks used for towing, carrying weight, or running aftermarket wheels instead of the original configuration.

How often should tires on a 2020 Chevrolet Trucks Silverado 3500 HD be inspected?

Tires on a 2020 Chevrolet Trucks Silverado 3500 HD should be inspected regularly, not only when tread looks low. Frequent visual checks for cuts, bulges, cracking, uneven wear, and air loss are worthwhile on a heavy-duty pickup, particularly if it tows, carries loads, or spends time parked between work cycles.

Inspection matters even more when the truck uses different wheel-and-tire setups across trims and configurations. A routine check of pressure, tread condition, and clearance can help catch problems before they become road issues, and any change in handling, ride quality, or wear pattern deserves a closer look by a qualified tire professional.
