Ram 1500/2500/3500: Tire Inflation Pressures
The proper cold tire inflation pressure is listed on the driver's side B-Pillar or rear edge of the driver's side door.
At least once a month:
- Check and adjust tire pressure with a good quality pocket-type pressure gauge. Do not make a visual judgement when determining proper inflation. Tires may look properly inflated even when they are underinflated.
- Inspect tires for signs of tire wear or visible damage.
CAUTION! After inspecting or adjusting the tire pressure, always reinstall the valve stem cap. This will prevent moisture and dirt from entering the valve stem, which could damage the valve stem.
Inflation pressures specified on the placard are always "cold tire inflation pressure." Cold tire inflation pressure is defined as the tire pressure after the vehicle has not been driven for at least three hours, or driven less than 1 mile (1.6 km) after a three hour period. The cold tire inflation pressure must not exceed the maximum inflation pressure molded into the tire sidewall.
Check tire pressures more often if subject to a wide range of outdoor temperatures, as tire pressures vary with temperature changes.
Tire pressures change by approximately 1 psi (7 kPa) per 12ºF (7ºC) of air temperature change. Keep this in mind when checking tire pressure inside a garage, especially in the winter.
Example: If garage temperature = 68ºF (20ºC) and the outside temperature = 32ºF (0ºC) then the cold tire inflation pressure should be increased by 3 psi (21 kPa), which equals 1 psi (7 kPa) for every 12ºF (7ºC) for this outside temperature condition.
Tire pressure may increase from 2 to 6 psi (13 to 40 kPa) during operation. DO NOT reduce this normal pressure build up or your tire pressure will be too low.
