2023 Chevrolet Silverado 3500HD Tire Size & Pressure Specs

When you're dealing with a heavy-duty workhorse like the 2023 Chevrolet Silverado 3500HD, running the right tire size, load rating, and air pressure isn't just about ride comfort—it’s a matter of critical safety and payload capacity. Whether you have a Single Rear Wheel (SRW) or Dual Rear Wheel (DRW) configuration, keeping your rubber in top shape is step one for towing and hauling.

Here is your comprehensive tire, pressure, and wheel specification guide for the 2023 Chevy Silverado 3500HD.

Quick answer

• OEM tire size: LT275/70R18 or LT275/65R20 (SRW); LT235/80R17 (DRW)
• Recommended cold tire pressure: 60 PSI Front / 70-80 PSI Rear (SRW); 65 PSI Front / 65 PSI Rear (DRW) (Always check your specific driver-side door placard)
• Bolt pattern: 8x180 mm
• Wheel size: 17x6.5 (DRW) / 18x8.0 or 20x8.5 (SRW)
• Load index/speed rating: Load Range E (121/118S or 125/122R for SRW; 120/117R for DRW)
• Spare tire size: Matches OEM sizing (LT275/70R18, LT275/65R20, or LT235/80R17) typically on a steel wheel
• TPMS frequency: 433 MHz

Tire sizes by trim

Because the 3500HD comes in both single-rear-wheel (SRW) and dual-rear-wheel (DRW) configurations across multiple trims, tire sizing varies significantly depending on how the truck was ordered.

Note: Some SRW models may be equipped with optional 17-inch wheels (LT265/70R17E) or aggressive mud-terrain options depending on the Z71 off-road package.

Recommended replacement tires

When replacing tires on a one-ton truck, always ensure you are purchasing Load Range E (10-ply rated) tires to maintain your payload and towing capacities.

1. Michelin Defender LTX M/S (Premium) – Exceptional highway longevity, wet traction, and ride quality for heavy towing.
2. Falken Wildpeak A/T3W (Mid-Range/Premium) – An aggressive all-terrain that handles heavy loads incredibly well without excessive road noise. Severe snow rated (3PMSF).
3. BFGoodrich All-Terrain T/A KO2 (Premium) – The industry standard for off-road durability and puncture resistance; excellent for job sites.
4. Firestone Transforce HT2 (Standard/Mid-Range) – A solid, budget-friendly commercial highway tire designed specifically for heavy-duty hauling.

When to inflate to max load psi

For HD trucks like the Silverado 3500HD, tire pressure management is dynamic. The door placard usually lists a high rear tire pressure (often 80 PSI for SRW) to account for maximum payload capacity.

• Towing/Hauling Heavy: Inflate the rear tires to the door placard's maximum rating (up to 80 PSI for a Load Range E tire) before loading the bed or dropping a heavy gooseneck/fifth-wheel trailer onto the hitch. This prevents sidewall flex, reduces heat buildup, and maintains stability.
• Unloaded/Daily Driving: If you drive the truck completely empty, running 80 PSI in the rear will result in an incredibly harsh ride and uneven center-tread tire wear. Many technicians recommend dropping the rear pressure to around 60-65 PSI when unloaded for better contact patch and ride quality, but you must remember to air back up before hauling.

Lug nut torque & pattern

• Bolt Pattern: 8x180 mm
• Lug Nut Torque: 140 lb-ft (190 Nm)
• Socket Size: 22mm (typically)

Technician Tip: Always hand-thread lug nuts first to prevent cross-threading the heavy-duty studs. Tighten in a crisscross (star) pattern and re-torque after 50-100 miles of driving, especially if hauling a heavy load.

Common tire issues for this vehicle

1. Cupping and Edge Wear on Front Tires: The heavy Duramax diesel engine puts immense weight on the front suspension. If shocks begin to wear or rotation intervals are skipped, front tires will quickly cup or wear the outer shoulders. Rotate every 5,000 to 7,500 miles.
2. Inner Dual Tire Neglect (DRW): The inner rear tires are notoriously difficult to check for pressure. An under-inflated inner dual will cause the outer dual to carry excessive weight, leading to catastrophic blowout of the outer tire. Use a dual-head pressure gauge and check them regularly.
3. TPMS Light with Changing Loads: Because drivers often adjust tire pressures based on whether they are towing or running empty, the TPMS system may trigger a low-pressure warning when pressures are dropped for unladen comfort.
