Chevrolet Silverado 1500 tires

The Silverado 1500 is sold on nine different tire fitments, and the tire label that tells you the right pressure for yours is on the B-pillar, not the door jamb. That is the single most useful thing on this page, because most owners look at the door edge, find nothing, and give up.

The sizes Chevrolet fitted

Across the T1 generation, from 2019, the recorded fitments are 255/70R17 112S and 265/70R17 115S on WT and LT; 265/65R18 114T on LT and RST; 275/60R20 115S on Custom, LT, RST, LTZ, High Country and both Trail Boss trims; and 275/50R22 111T on LT, RST, LTZ and High Country.

Off-road and work builds use LT-metric tires instead: LT275/65R18 load range C on WT, LT and the Trail Boss trims, with LT265/70R17 C, LT265/60R20 C on the 20 inch Trail Boss and LT275/70R18 C on the ZR2. An LT tire is a different animal from the P-metric tire of the same nominal size. It carries more, runs at a higher pressure and has a stiffer casing. One truck has that many correct answers because wheel, trim and payload package all move the fitment. It also means the tires on the truck today may not be the ones named on the placard, which changes the target pressure. See finding your tire size.

Where the Silverado hides its tire label

GM is specific. The 2022 owner's manual states that a vehicle-specific Tire and Loading Information label is attached to the centre pillar, and it names the B-pillar in brackets. The B-pillar is the upright post between the front and rear doors. Open the driver's door and turn to look at the body of the truck rather than at the door edge.

Generic advice tells people to check the driver's door jamb. That works on a Toyota or a Honda and fails here, as it does on a Ram, a Nissan, a Subaru or a Tesla. If you have been hunting the door and finding only a sticker about airbags, look at the post.

What the label tells you

Four things: cold pressure front, cold pressure rear, the original tire size, and the spare. GM defines cold as parked at least three hours, or driven under a mile. Pressure climbs as a tire warms, so a reading taken after a drive is high and will lead you into underinflating.

We do not publish a PSI figure for the Silverado. Pages 339 and 340 of the 2022 manual cover tire pressure and TPMS and print no number, because the right number depends on which of those nine fitments you have. The one aggregator that answered our request gives a six PSI step between the standard and LT fitments, which is plausible but uncorroborated, and a pressure error on a load-carrying truck tire has consequences. See our tire pressure placard guide for why the lookup sites disagree.

Replacing fewer than four

GM recommends replacing worn tires in complete sets of four, so that tread depth stays uniform, and says that where only one axle is replaced the new tires go on the rear. It also asks for the original TPC Spec number to be matched rather than just the size. GM publishes no numeric tread-depth tolerance for a four-wheel-drive Silverado. If your truck is 4WD and the other three tires are worn, ask us before committing to one. See how many tires do I need and mixing tire brands.

Matching size alone is not enough on this truck. Load range and TPC Spec have to match too, especially on Trail Boss and ZR2 builds.

What changes on a mobile Silverado fitting

• Many trims have caps over the wheel nuts that unscrew counter-clockwise with the wheel wrench before the nuts are reachable, plus centre caps that sometimes need prying. They add time and they break.
• Power-assist running boards must be disabled before anything goes under the truck. GM prints that as a personal-injury warning.
• Direct TPMS, one sensor per wheel transmitting to a receiver in the truck. Sensors are transferred or replaced on a wheel swap, and the malfunction telltale gets checked after fitting.
• Wheels span 17 to 22 inches. The 275/50R22 fitment on LTZ, High Country and RST is low profile and unforgiving of kerbs.
• The full-size spare sits under the rear on a cable hoist. GM notes it loses air over time, so it is worth checking while we are there.
• GM does not print a wheel nut torque figure in the tire sections we read, so we take the torque from the manual in your truck rather than working from memory.

What we do

We supply the tires and fit them where the truck is parked. Pressures are set to the label on your B-pillar, the TPMS is reset or relearned where the truck supports it, and the old tires go with us. Pricing is on our mobile tire replacement page.

Questions people ask

• Where is the tire pressure sticker on a Silverado? On the B-pillar, the post between the doors. GM says so in the owner's manual. It is not on the door edge.
• What PSI should I run? The figure on that label, for your axle and your tire size. GM prints no number in the manual and we will not invent one.
• Can I put P-metric tires on a Trail Boss? Not without a conversation. Those trucks run LT-metric load range C tires and the load range is part of the specification.
• Do I have to buy four? GM's manual asks for sets of four. Two is workable in some cases, and if we fit two they go on the rear axle.
• Will the pressure warning clear after you fit? Yes, where the truck supports a roadside reset or relearn. We check the telltale before leaving.
• Can you deal with the wheel nut caps? Yes. They are a known nuisance here and we carry what they need.
