General Motors is recalling a small batch of heavy-duty pickups after discovering the tire-pressure placard on certain 2024-2025 Chevrolet Silverado 2500 HD and GMC Sierra 2500 HD trucks listed the wrong rear tire pressure. The error, filed with federal regulators as NHTSA campaign 26V530, affects just eight trucks built with a specific towing and wheel combination, but the safety math behind it applies to any heavy-duty truck owner who loads up for towing.

Key Points

• GM’s recall, filed under NHTSA campaign 26V530 and internal number N262561970, covers 2024-2025 Chevrolet Silverado 2500 HD and GMC Sierra 2500 HD trucks equipped with the enhanced towing package and dealer-installed 20-inch accessory wheels.
• Only eight vehicles are involved, five Chevrolets and three GMCs, according to GM Authority’s review of the filing.
• The tire-pressure label on the affected wheel package listed 70 psi for the rear tires instead of the required 80 psi, and the engine control module carried matching incorrect calibration data.
• FleetOwner reports the mismatch can also stop the tire pressure monitoring system from properly flagging low pressure.

Why the Mislabel Matters

Ten psi does not sound like much, but on a heavy-duty pickup rated to tow near its maximum, it is the difference engineers built the tire’s load capacity around. Rear tire pressure on a 2500-series truck is calibrated to the vehicle’s gross axle weight rating, not just curb weight. Underinflated tires flex more under load, run hotter, and lose the reserve capacity needed to safely carry a loaded trailer’s tongue weight.

GM’s own filing, as detailed by GM Authority, warns that underinflated tires can “reduce tire performance when towing very heavy loads, increasing the risk of a crash.” Compounding the problem, the affected trucks’ tire pressure monitoring system was calibrated to the same wrong figure, so it would not warn a driver that the tires had actually dropped below a safe working pressure. A system built to catch underinflation was, in this case, blind to it.

What’s Affected

• 2024 and 2025 Chevrolet Silverado 2500 HD
• 2024 and 2025 GMC Sierra 2500 HD
• Only trucks built with the enhanced towing option combined with the dealer-installed 20-inch accessory tire and wheel package
• Eight total vehicles confirmed in the population, per FleetOwner’s recall roundup

What Owners Should Do

• GM dealers will reflash the engine control module with corrected calibration values at no charge.
• Technicians will apply a corrected tire-pressure label over the existing placard and reinflate the rear tires to the proper 80 psi.
• The tire pressure monitoring system will be recalibrated so it recognizes the correct target pressure going forward.
• Owner notification letters are expected to go out around September 28, 2026, according to GM’s filing cited by GM Authority.
• Chevrolet owners can call 800-222-1020 and GMC owners 800-462-8782 to confirm whether their specific VIN is included.

The recall population is tiny, but it is a reminder that the tire information placard on any truck’s doorjamb is not boilerplate. It is a calibrated number tied to how much weight that specific tire and wheel combination is engineered to carry, and it is worth double-checking against the tire’s actual sidewall rating any time a dealer-installed wheel package enters the picture.
