Chevrolet Silverado 1500 Tire Pressure (Recommended PSI)
TL;DR
Most P-metric Silverado 1500 tires run 30-36 PSI depending on model year, but LT-metric (load-range) tires on the same truck can require 41-45 PSI - always check your own door placard.
Why one PSI figure will not fit your Silverado
The Chevrolet Silverado 1500 has been sold with dozens of tire-size and trim combinations across three generations, and General Motors sets a different cold-inflation pressure for each combination. The single biggest split is between P-metric (passenger-metric) tires and LT-metric (light-truck metric, load-range) tires: LT tires are built to carry heavier payloads and trailer tongue weight, so they are specified at noticeably higher pressure - often 41-45 PSI versus 30-36 PSI for P-metric sizes on the same generation.
2019-2024 (fourth generation, T1XX)
Standard P-metric sizes such as 255/70R17, 265/65R18, 265/70R17 and 275/60R20 are specified at 35 PSI, and the 275/50R22 wheel-and-tire package used on higher trims is specified at 36 PSI. The LT-metric options change the picture: LT275/65R18 (Trail Boss packages) calls for 41 PSI, and LT265/70R17 (LT and WT work-truck configurations) calls for 45 PSI.
2014-2018 (third generation, K2XX)
P-metric tires on this generation are lower than the newer trucks in some configurations: P275/55R20 and P285/45R22 are specified at 32 PSI on High Country trim, while P255/70R17 and P265/70R17 on LS/LT/WT trims sit at 35 PSI. The LT265/70R17 option again jumps to 45 PSI.
2007-2013 (second generation, GMT900)
This generation shows the widest trim-level spread: the base P275/55R20 setup on LT and LTZ trims is specified at only 30 PSI, most P245/70R17 and P265/70R17 combinations sit at 35 PSI, and the LT245/70R17 off-road/heavy-duty option again requires 45 PSI.
Where to find your truck's real number
Because the correct pressure depends on the exact tire size fitted to your specific truck, always confirm the figure on the yellow tire and loading information placard on the driver's doorjamb, or in the Tires and Wheels section of your owner's manual. Do not use the number molded into the tire sidewall - that is the tire's maximum cold pressure rating, not GM's recommended pressure.

Frequently asked questions
Is front and rear tire pressure the same on a Silverado 1500?
For the tire sizes we could verify across all three generations, GM specifies the same cold pressure for the front and rear axle. That is different from many cars that split front and rear values, so always read both numbers off your specific placard to confirm it applies to your truck.
Why does my Silverado's placard say 45 PSI when the tire shop said 35?
You likely have an LT-metric (load-range) tire rather than a P-metric tire. LT-metric tires are built for heavier loads and trailering and GM specifies them at a much higher cold pressure - 41 to 45 PSI depending on size - even though the truck otherwise looks identical to a P-metric-equipped model.
Can I just use the maximum pressure printed on the tire sidewall?
No. The sidewall number is the tire's maximum cold inflation pressure, not Chevrolet's recommended pressure for your vehicle. Always use the figure from the driver's doorjamb placard or owner's manual, which accounts for the truck's weight and handling characteristics.
Does towing or hauling change my recommended tire pressure?
Yes, on many Silverado 1500 configurations the placard lists a higher pressure for heavy loads or trailering in addition to the normal cold-inflation pressure. Check your owner's manual towing section and the placard for a loaded-condition figure specific to your tire size.
