2020 Chevrolet Silverado 2500HD Tire Size & Pressure Guide

As an ASE-certified master technician, I know that heavy-duty trucks like the 2020 Chevrolet Silverado 2500HD require precise tire maintenance to perform their best. Whether you're towing a fifth-wheel trailer, hauling heavy payloads, or just using your truck as a daily driver, having the correct tire size, load rating, and air pressure is critical for safety and longevity. Here is your comprehensive guide to the 2020 Chevy Silverado 2500HD tire and wheel specs.

Quick answer

• OEM tire size: LT245/75R17, LT275/70R18, or LT275/65R20 (depending on trim/package)
• Recommended cold tire pressure (door placard): Front: 60 PSI / Rear: 70 PSI (varies slightly by configuration)
• Bolt pattern: 8x180 mm
• Wheel size: 17x7.5", 18x8", or 20x8.5" (Offset: +44mm to +47mm)
• Load index/speed rating: 121/118S to 126/123R (Load Range E is mandatory)
• Spare tire size: Full-size matching spare (typically LT245/75R17 or LT275/70R18 on a steel wheel)
• TPMS frequency: 433 MHz

Tire sizes by trim

Chevrolet offered the 2020 Silverado 2500HD in multiple trims, from bare-bones work trucks to luxury haulers. Always verify with your door jamb sticker before purchasing.

Recommended replacement tires

When replacing tires on a 2500HD, always stick to Load Range E (10-ply rated) tires to maintain the truck's towing and payload capacities. Here are some of the most reliable options available today:

1. Michelin Defender LTX M/S – Premium ($$$). The gold standard for highway hauling. Extremely quiet, long-lasting tread, and excellent wet traction.
2. BFGoodrich All-Terrain T/A KO2 – Premium ($$$). A legendary all-terrain tire that provides aggressive off-road capability without sacrificing too much highway comfort. Severe snow rated (3PMSF).
3. Falken Wildpeak A/T3W – Mid-range ($$). An incredible value for HD truck owners needing all-weather, all-terrain performance. Outstanding tread life and winter capability.
4. Cooper Discoverer HT3 – Mid-range ($$). A great commercial-grade highway tire for fleets and owners who strictly stick to the pavement and need durability on a budget.

When to inflate to max load psi

Because this is a heavy-duty truck, tire pressure management is crucial. Your door placard typically recommends 60 PSI in the front and 70 PSI in the rear for standard driving.

However, when you are hauling a payload near the truck's maximum capacity (up to 3,900+ lbs depending on configuration) or towing a heavy gooseneck/fifth-wheel trailer with high tongue weight, you should inflate the rear tires to 80 PSI (the maximum cold inflation pressure for Load Range E tires). This prevents the tire sidewalls from overheating and flexing under heavy loads, which can lead to blowouts. Always drop the rear tire pressure back down to 70 PSI when unloaded to avoid a harsh, bouncy ride and premature center tread wear.

Lug nut torque & pattern

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

Tech tip: Always use a calibrated torque wrench. Do not use an impact gun to perform the final tightening on these heavy-duty wheels. Re-torque the lug nuts after the first 50 to 100 miles of driving after a wheel has been removed.

Common tire issues for this vehicle

1. Premature edge wear on front tires: The heavy Duramax diesel engine (if equipped) puts massive weight on the front end. If the truck isn't aligned regularly or driven on winding roads, the outer edges of the front tires will wear out quickly. Rotate tires every 5,000 to 7,500 miles.
2. TPMS sensor failure: The 433 MHz sensors are generally reliable, but corrosion from road salt or changing heavy-duty tires can easily damage the valve stems.
3. Center tread wear on rear tires: Caused by running 80 PSI in the rear tires when the truck's bed is empty. Adjust your pressures according to your load!
