2014 Chevrolet Silverado 3500HD Tire Size & Pressure Guide

As an ASE-certified master technician, I’ve serviced countless heavy-duty trucks over the years, and the 2014 Chevrolet Silverado 3500HD is a regular in the bays. When you are dealing with a one-ton truck capable of hauling massive fifth-wheel trailers and heavy payloads, getting your tire specifications right isn't just about ride quality—it’s a critical safety issue.

Whether you are running a Single Rear Wheel (SRW) or Dual Rear Wheel (DRW/Dually) setup, here is your comprehensive tire, wheel, and pressure guide for the 2014 Chevy Silverado 3500HD.

Quick answer

• OEM Tire Size: LT265/70R18 (SRW standard) or LT235/80R17 (DRW standard). LT265/60R20 is also an option for higher SRW trims.
• Recommended Cold Tire Pressure (Door Placard):
  • SRW: 60 PSI Front / 70-80 PSI Rear
  • DRW: 65 PSI Front / 65 PSI Rear (varies slightly by payload package)
• Bolt Pattern: 8x180 mm
• Wheel Size: 18x8.0 (SRW) or 17x6.5 (DRW). 20x8.5 is optional on SRW.
• Load Index / Speed Rating: Minimum Load Range E (10-ply rated). Typically 123/120R or 120/117R depending on SRW vs. DRW.
• Spare Tire Size: Matches the OEM sizing (LT265/70R18 or LT235/80R17).
• TPMS Frequency: 315 MHz (Note: DRW inner tires may not have standard TPMS sensors depending on the exact build, but SRW and outer DRW use 315 MHz).

Tire sizes by trim

The tire size on your 2014 Silverado 3500HD is dictated less by the trim level (WT, LT, LTZ) and more by whether your truck is configured as a Single Rear Wheel (SRW) or Dual Rear Wheel (DRW). Always verify your specific setup on the driver’s side door jamb placard.

Recommended replacement tires

Because the 3500HD requires Load Range E tires to safely handle its gross vehicle weight rating (GVWR), you cannot cheap out on passenger-rated (P-metric) tires. Here are my top recommendations based on durability and customer feedback:

1. Michelin Defender LTX M/S (Premium / Highway): The undisputed king of heavy-duty highway tires. They offer an incredibly smooth ride, long tread life, and handle wet weather exceptionally well. Perfect for dedicated highway haulers.
2. BFGoodrich All-Terrain T/A KO2 (Premium / All-Terrain): If your 3500HD works on job sites, farms, or sees mud and snow, this is the gold standard. They feature tough sidewalls to resist punctures while still handling heavy towing weights securely.
3. Cooper Discoverer HT3 (Mid-Tier / Commercial): A fantastic budget-friendly commercial highway tire. It offers great treadwear and stability under load without carrying the Michelin price tag.

When to inflate to max load psi

Since this is a heavy-duty truck, understanding your tire pressure is crucial. The door placard gives you the recommended everyday pressure, but the sidewall of a Load Range E tire usually lists a maximum of 80 PSI cold.

You should inflate your rear tires to the maximum 80 PSI only when you are hauling a heavy payload in the bed or towing a heavy gooseneck/fifth-wheel trailer with high tongue weight. Inflating to 80 PSI increases the tire's load-carrying capacity and stiffens the sidewall, reducing dangerous sway. When driving unloaded, running 80 PSI will result in a harsh ride and premature center tread wear, which is why the placard often recommends dropping the rear pressure to 65-70 PSI when unladen.

Lug nut torque & pattern

• Torque Specification: 140 lb-ft
• Bolt Pattern: 8x180 mm (Chevrolet updated from the classic 8x165.1mm in 2011 for the HD trucks, so older wheels will not fit).

Always use a calibrated torque wrench and tighten the lug nuts in a crisscross (star) pattern. With a heavy-duty truck, I strongly recommend re-checking the torque after 50 to 100 miles of driving following a wheel installation.

Common tire issues for this vehicle

• Front-End Cupping: The heavy Duramax diesel engine puts a lot of weight on the front end. If you don't rotate your tires every 5,000 to 7,500 miles, the front tires will often develop a "cupped" or scalloped wear pattern, leading to a loud, roaring noise at highway speeds.
• Dually Inner-Tire Neglect: On DRW models, the inner rear tires are notoriously hard to check. Drivers often neglect them, leading to under-inflation. A blowout on the inner tire can severely damage the outer tire and the truck's fender. Get a long dual-head tire pressure gauge and check them regularly.
• TPMS Sensor Failure: Because this truck is a 2014, the original TPMS sensor batteries are well past their 7-10 year lifespan. If your tire pressure light is flashing and then stays solid, you likely have a dead sensor rather than a flat tire.
