2024 Chevrolet Silverado 2500HD — Tire Size & Pressure Guide

Quick answer

• OEM tire size (typical from factory):
  • LT245/75R17 E, LT275/70R18 E, or LT275/65R20 E (varies by trim/package)
• Recommended cold tire pressure (door placard):
  • Front: ~60–65 psi
  • Rear: ~60–75 psi
  • Exact values vary by engine/trim/tire size—confirm on the driver’s door jamb
• Bolt pattern: 8x180 mm (8-lug GM HD)
• Factory wheel sizes and offset:
  • 17x7.5–8.0, 18x8.5, or 20x8.5; offset typically +40 to +50 mm
• Load index / speed rating (common):
  • LI 121–126 (E‑load, 10‑ply rated); Speed R–S (106–112 mph). Check sidewall for your exact tire.
• Spare tire size: Full‑size LT spare on a steel wheel; usually matches or is diameter‑equivalent to the primary set (e.g., LT245/75R17 E, LT275/70R18 E, or an 18" spare for 20" packages)
• TPMS sensor frequency: 433 MHz on most 2020–2024 GM HD trucks (verify by VIN or sensor supplier)

Tire sizes by trim

Notes:

• Exact fitment can vary by drivetrain, axle rating, and option packages. Always confirm your truck’s door‑placard size and PSI.

Recommended replacement tires

• Highway all‑season (quiet, towing stability):
  • Michelin Defender LTX M/S (E‑load). Premium ride and wet grip. Typical price: $340–$450/tire (18–20").
  • Bridgestone Duravis R500 HD or Firestone Transforce HT2. Durable commercial‑grade casings. ~$280–$380/tire.
• All‑terrain (balanced on/off‑road):
  • BFGoodrich All‑Terrain T/A KO2 (E‑load). Proven durability, snow‑rated. ~$320–$420/tire.
  • Falken Wildpeak A/T3W or General Grabber A/TX. Strong winter traction for the price. ~$260–$360/tire.
• Winter (severe snow/ice):
  • Nokian Hakkapeliitta LT3 or Bridgestone Blizzak LT. Outstanding cold‑weather control. ~$330–$440/tire.

Prices vary by size and market—use E‑load (or higher, if specified) and match the load index and speed rating on your door placard or greater.

When to inflate to max load psi

Heavy‑duty Silverado 2500HD models ship with LT “E‑load” tires rated up to 80 psi cold (check the sidewall for “Max Load … at 80 PSI”). Use the door‑placard pressures (often ~60–65 psi front, ~60–75 psi rear) for everyday driving when unloaded. Increase pressures toward the tire’s and wheel’s rated maximums when:

• Carrying payloads near GVWR
• Towing heavy trailers with high tongue/pin weight
• Sustained highway towing in hot ambient conditions

Guidelines:

• Rear tires typically carry more load—raise rears first (e.g., 70–80 psi) and fronts as needed (often 60–70 psi) while staying within wheel PSI limits. Never exceed the lower of the tire or wheel maximum.
• Recheck pressures cold, and adjust after significant temperature swings or altitude changes.

Lug nut torque & pattern

• Lug pattern: 8 lugs on 8x180 mm hub circle
• Lug nut thread: M14 x 1.5, 60° conical seat (typical GM HD)
• Torque: ~140 lb‑ft (190 N·m) is commonly specified for GM HD 8‑lug wheels. Verify in your owner’s manual.
• Tightening pattern: Star/diagonal sequence; re‑torque after 50–100 miles on new wheels/tires.

Common tire issues for this vehicle

• Underinflation when towing: Leads to heat buildup and shoulder wear. Set pressures for the actual load; many owners benefit from running higher rear PSI when hauling.
• Outer‑edge front wear: Added front axle weight (diesel, plow mounts, or leveling kits) can increase toe/camber wear. Get a heavy‑duty alignment with your typical load onboard.
• Cupping/heel‑toe on aggressive A/T tread: Rotate every 5–7k miles; keep shocks in good condition.
• TPMS service: 2020+ HD trucks generally use 433 MHz sensors; mismatched frequencies during wheel swaps can trigger warnings. Perform a TPMS relearn after rotations or tire changes.
• Ride firmness on 20" E‑load tires: Higher unsprung weight and stiff sidewalls can transmit more road harshness; consider 18" packages for more sidewall if comfort is a priority.
