Ram 1500 Tire Pressure (Recommended PSI)
TL;DR
Cold tire pressure varies widely by trim and tire size on the Ram 1500 - roughly 35 to 55 psi depending on configuration - so always confirm the figure on your own truck's door placard.
Why there is no single Ram 1500 tire pressure figure
The Ram 1500 has been sold with many different factory tire sizes across its generations, and each combination of tire size, load range, and trim carries its own recommended cold inflation pressure. A truck fitted with an off-road LT-metric tire (like the Rebel package) needs meaningfully higher pressure than a truck fitted with a passenger P-metric tire on a standard trim. Never assume one number applies to every 1500 - the correct figure is the one printed for your specific truck.
Where to find your exact figure
- The tire and loading information placard on the driver door edge or door jamb - this is the manufacturer's official figure for your exact vehicle as built.
- Your owner's manual, in the tire and wheel section.
- The tire sidewall shows the tire's maximum pressure rating, which is not the same as the recommended cold pressure - do not inflate to the sidewall max unless the placard says so.
Verified figures by generation and configuration
The table below reflects figures found in tire-pressure reference sources cross-checked against reported placard data. Some trims are omitted because a reliable figure could not be confirmed - for those, check your own placard.
| Generation / years | Trim or tire size | Front (PSI) | Rear (PSI) |
|---|---|---|---|
| 4th Gen (2013-2018, DS/DJ) | P275/60R20 (Big Horn, Laramie, Lone Star, Sport, ST) | 35-39 | 35-39 |
| 4th Gen (2013-2018, DS/DJ) | P265/70R17 (SXT, SLT, Tradesman, HFE) | 40 | 40 |
| 4th Gen (2013-2018, DS/DJ) | LT265/70R17 (Outdoorsman/Tradesman off-road package) | 43 | 43 |
| 4th Gen (2013-2018, DS/DJ) | LT285/70R17 (Rebel) | 55 | 45 |
| 4th Gen (2013-2018, DS/DJ) | 285/45R22 (Sport Regular Cab) | 35 | 35 |
| 5th Gen (2019-2024, DT) | 275/55R20, 275/65R18, 285/45R22 (SXT, Sport, Lone Star) | 36 | 36 |
| 5th Gen (2019-2024, DT) | LT275/65R18 (Lone Star off-road option) | 38 | 38 |
Trims not shown
Big Horn, Laramie, Laramie Longhorn, Limited, Rebel, and Tradesman on the 5th generation (2019-2024) list various tire sizes across reference sources, but a consistent verified PSI figure could not be confirmed for all of them. Read the number directly off your own door placard for these configurations rather than relying on a guess.
Front vs rear differences
Some configurations - most notably the Rebel's LT285/70R17 tire - use a higher front pressure than rear pressure because of the truck's front-heavier unladen weight distribution and the tire's load range. Always inflate front and rear to the two separate numbers shown on your placard rather than a single average figure.
Summary

Frequently asked questions
Is 35 psi correct for all Ram 1500 trucks?
No. 35 psi appears on some P275/60R20 and 285/45R22 configurations from the 4th generation, but 5th-generation trucks commonly call for 36 psi, off-road LT-metric tires call for 43 psi, and the Rebel calls for 55 psi front and 45 psi rear. Check your own door placard rather than assuming 35 psi applies.
Where exactly is the tire pressure placard on a Ram 1500?
It is a sticker on the driver-side door edge or door jamb, visible when the door is open. It lists the original-equipment tire size, the cold inflation pressure for front and rear axles, and the maximum load.
Why does my Ram 1500 owner's manual show a different number than a website?
Websites often show a single figure while your specific truck may have an optional tire size or off-road package with its own pressure rating. The placard and owner's manual for your exact build are the only fully reliable sources.
Should I inflate to the maximum pressure printed on the tire sidewall?
No. The sidewall number is the tire's maximum pressure rating, not the recommended cold pressure for your vehicle. Use the lower figure from your door placard or owner's manual unless towing guidance specifically instructs a higher pressure.
