2019 Chevrolet Silverado 3500HD — Tire Size & Pressure

The 2019 Chevrolet Silverado 3500HD is a heavy-duty powerhouse designed to haul, tow, and carry massive payloads. To do that safely and efficiently, it requires the right tires, properly inflated and maintained. Whether you have a Single Rear Wheel (SRW) or Dual Rear Wheel (DRW) configuration, understanding your truck’s tire and wheel specifications is critical for safety and performance.

Quick answer: 2019 Chevrolet Silverado 3500HD Tire & Wheel Specs

• OEM Tire Size: LT235/80R17 (DRW), LT265/70R18 (SRW), or LT265/60R20 (SRW)
• Recommended Cold Tire Pressure (Door Placard): 60 PSI Front / 65-80 PSI Rear (Depends on SRW/DRW and payload rating; always check the driver's door jamb)
• Bolt Pattern: 8x180 mm
• Wheel Size: 17x6.5 (DRW), 18x8.0 (SRW), or 20x8.5 (SRW)
• Load Index / Speed Rating: 120/117 R (DRW) or 124/121 S (SRW) – Load Range E (10-ply rated) is strictly required.
• Spare Tire Size: Matches OEM production tire sizes (LT235/80R17, LT265/70R18, or LT265/70R17 depending on wheel options).
• TPMS Frequency: 315 MHz or 433 MHz (varies by build date and RPO code, confirm with a TPMS scan tool).

Tire sizes by trim

Tire sizes for the 2019 Silverado 3500HD depend heavily on whether the truck is equipped with dual rear wheels (dually) or single rear wheels, rather than just the trim level.

Note: Always verify your specific tire size on the sidewall before purchasing replacements, especially if you have a 4WD vs 2WD model.

Recommended replacement tires

When replacing tires on a 1-ton truck, it is non-negotiable to use Load Range E tires. Here are top recommendations based on durability, towing stability, and traction:

• Michelin Defender LTX M/S (Premium): The gold standard for highway hauling. Exceptionally quiet, long-lasting, and offers supreme stability under heavy loads.
• BFGoodrich All-Terrain T/A KO2 (Premium): Best for worksite access, off-roading, and snow. A highly durable 3-peak mountain snowflake (3PMSF) rated all-terrain.
• Firestone Transforce HT2 (Mid-Tier): A popular OEM-style commercial highway tire. Great for fleet owners looking for high mileage at a reasonable price point.
• Cooper Discoverer AT3 LT (Mid-Tier): A fantastic balance of highway comfort and off-road capability with excellent treadwear warranties.

When to inflate to max load psi

Because the 3500HD is a heavy-duty truck, tire pressures are dynamic based on what you are doing. The tires are Load Range E, which means they have a maximum cold inflation pressure of 80 PSI.

You should inflate your rear tires to the maximum placard pressure (often 80 PSI for SRW, or 65 PSI for DRW) when you are:

1. Towing a heavy gooseneck or fifth-wheel trailer.
2. Maxing out the payload capacity in the bed.
3. Operating at or near your Gross Vehicle Weight Rating (GVWR) or Gross Rear Axle Weight Rating (GAWR).

If you are driving the truck empty, running 80 PSI in the rear will result in a bone-jarring ride and accelerated center-tread wear. It is common practice to drop the rear tire pressure down closer to 60 PSI when completely unloaded, but you must remember to air them back up before hitching up a trailer.

Lug nut torque & pattern

Proper wheel installation is a matter of life and death on a 1-ton truck. The 2019 Chevy Silverado 3500HD uses a massive 8x180 mm bolt pattern.

• Lug Nut Torque: 140 lb-ft (190 Nm)
• Lug Nut Thread Size: M14 x 1.5

When tightening, always use a calibrated torque wrench and a cross-star pattern. If you are installing wheels on a DRW (dually) truck, ensure there is no rust or debris sandwiched between the dual mating surfaces, as this can cause the wheels to loosen while driving. Re-torque the lug nuts after 50-100 miles of driving anytime the wheels are removed.

Common tire issues for this vehicle

• TPMS Sensor Failures: The TPMS sensors run on lithium-ion batteries that typically die after 5-7 years. For a 2019 model, you may start seeing TPMS fault lights on the dash. When replacing tires, it’s a good idea to test or replace the sensors.
• Uneven Dually Wear: On DRW trucks, the inner rear tires often wear differently than the outers. Proper rotation is required (which can be labor-intensive and requires dismounting if the wheels have different finishes).
• Cupping on Front Tires: The heavy diesel engine option (Duramax) puts massive weight on the front end. Failing shocks or infrequent tire rotations will cause severe cupping and roaring noises from the front tires.
