2023 Chevrolet Silverado 1500 — Tire Size & Pressure Guide

Quick answer

• OEM tire size(s): Depends on trim. Common factory fits include 255/70R17, 265/65R18, 275/60R20, 275/50R22; off‑road trims: 275/65R18 (Trail Boss) and LT275/70R18 (ZR2)
• Recommended cold tire pressure (door placard):
  • P‑metric street tires (17/18/20/22 in): typically 35 psi front / 35 psi rear
  • LT‑metric off‑road tires (Trail Boss/ZR2): commonly 50–60 psi front & rear (verify your placard)
• Bolt pattern: 6x139.7 mm (6x5.5")
• Factory wheel sizes/offsets: 17x8, 18x8.5, 20x9, 22x9; typical offsets +24 to +28 mm (Trail Boss/ZR2 often ~+18 to +24 mm)
• Load index / speed rating: P‑metric commonly 111–117, S–H; LT‑metric off‑road tires usually Load Range C/D/E, Q–S
• Spare tire: Full‑size steel spare for most trims, typically 255/70R17 or 265/70R17; off‑road trims may carry an 18‑inch full‑size
• TPMS frequency: Typically 433 MHz on 2023 models; some fleet/service builds may use 315 MHz—verify by VIN/part lookup

Tire sizes by trim

Recommended replacement tires

• Daily/highway (premium):
  • Michelin Defender LTX M/S2 — excellent tread life and wet grip; sizes for 17–22 in
  • Bridgestone Alenza AS Ultra — quiet, confident all‑season for 18–22 in wheels
• All‑terrain (balanced):
  • BFGoodrich All‑Terrain T/A KO2 — proven durability; sizes incl. 275/65R18, 275/60R20
  • Falken Wildpeak A/T3W — strong snow/wet performance; popular in 18/20 in
• Off‑road biased (Trail Boss/ZR2):
  • Goodyear Wrangler Duratrac or Territory MT (OE‑style) — aggressive traction; LT275/65R18 or LT275/70R18
• Value/budget:
  • General Grabber HTS60 (highway) or APT (mild A/T) — solid performance per dollar in 17–20 in Choose replacement tires that meet or exceed your door‑placard load index and speed rating. If you tow/haul regularly, consider LT‑metric all‑terrain options and have pressures adjusted to load per placard or load‑inflation tables.

When to inflate to max load psi (HD trucks only)

This article covers the 1500 (light‑duty), not Silverado 2500/3500 HD. Do not inflate to the tire’s sidewall “Max Pressure” on a 1500 unless specified by your door placard. On HD trucks with LT‑E tires, “Max Load @ Max PSI” may be appropriate when near GVWR/GAWR; otherwise follow the placard. For Silverado 1500 trims equipped with LT tires (Trail Boss/ZR2), use the placard pressures (often 50–60 psi). Increase only when carrying heavy loads or towing within ratings, and never exceed wheel or tire limits.

Lug nut torque & pattern

• Lug nut torque: 140 lb‑ft (190 N·m) typical for 2023 Silverado 1500
• Thread size: M14 x 1.5
• Bolt pattern: 6x139.7 mm (6x5.5")
• Hub/center bore: ~78.1 mm Tighten in a star pattern on the 6‑lug hub, re‑torque after 25–50 miles on new wheels.

Wheel size and offset notes

• Factory widths: ~8.0 in (17"), 8.5 in (18"), 9.0 in (20/22")
• Typical offsets: +24 to +28 mm (ZR2/Trail Boss packages can be closer to +18 to +24 mm for wider stance)
• Aftermarket fitment: Aggressive negative offsets can cause poke and fender/liner rub at full lock or compression, especially with 33–34 in tires.

Common tire issues for this vehicle

• Edge/heel‑toe wear on all‑terrains if rotations are stretched; rotate every 5–7k miles
• Rub on liners or control arms when upsizing beyond ~33 in or when using low/negative offset wheels
• Feathering from toe‑out after lift/level kits; get a post‑install alignment and consider UCAs for large lifts
• TPMS relearn needed after rotations or wheel swaps; sensors are typically 433 MHz on 2023 models
• Payload/towing: Under‑inflation on LT tires causes heat and shoulder wear; follow placard and adjust for load
