Ram 2500 Tire Pressure (Recommended PSI)
TL;DR
Gas (Hemi) SRW Ram 2500s commonly placard near 60 front / 80 rear PSI, while Cummins diesel SRW trucks commonly placard near 80 front / 65 rear PSI - but this varies by trim and tire size, so check your own door jamb.
Why there is no single Ram 2500 tire pressure
The Ram 2500 is sold with multiple engines (Hemi V8 gas and Cummins inline-6 diesel), multiple tire sizes, and both single-rear-wheel (SRW) and dual-rear-wheel (DRW, or dually) configurations. Chrysler/Ram sets a specific cold inflation pressure for each combination, printed on a placard on the driver's door edge or B-pillar, and repeated in the owner's manual. Because the diesel engine adds significant front-axle weight and dually rear axles use a different tire size and duty rating, the correct PSI is genuinely different truck to truck - it is not one universal figure.
What owners have reported on their placards
Multiple independent owner reports (forum posts describing their own door placards) consistently describe two different patterns. On gas-powered 6.4L Hemi SRW trucks, owners report a placard reading of about 60 PSI front and 80 PSI rear. On Cummins 6.7L diesel SRW trucks, owners report a placard reading of about 80 PSI front and 65 PSI rear. A separate range of sources describes an overall span of roughly 60 to 80 PSI across Ram 2500 configurations, which matches the individual reports above. We could not find a reliably corroborated pair of numbers specifically for dual-rear-wheel (DRW) trucks, so no DRW figure is stated here - check your own placard for that configuration.
How to find the correct pressure for your truck
The only fully reliable source is your own vehicle: open the driver's door and look at the placard on the door edge or the B-pillar, or check the tire and loading information section of your owner's manual. If you have changed tire size from the factory-fitted size, use the pressure for your installed tire size and load range, not the printed placard number, and consult the tire manufacturer or a tire shop.
| Generation / years | Trim or tire size | Front (PSI) | Rear (PSI) |
|---|---|---|---|
| 4th/5th gen, 2010-2025 (approx.) | 6.4L Hemi gas, SRW | ~60 (owner-reported) | ~80 (owner-reported) |
| 4th/5th gen, 2010-2025 (approx.) | 6.7L Cummins diesel, SRW | ~80 (owner-reported) | ~65 (owner-reported) |
| All years | Dual-rear-wheel (DRW / dually), any engine | Not corroborated - check door placard | Not corroborated - check door placard |
| All years | Any trim, general range seen across sources | 60-80 (range, sources vary) | 60-80 (range, sources vary) |
Key takeaway
- Do not assume one PSI figure applies to every Ram 2500 - engine, tire size, and SRW vs DRW all change the correct pressure.
- Gas SRW trucks tend to run lower front / higher rear pressure; diesel SRW trucks tend to run higher front / lower rear pressure, per owner-reported placards.
- Your own door placard and owner's manual are the only fully authoritative source for your specific truck.
Summary
| Gas 6.4L Hemi SRW - front | ~60 PSI (owner-reported) |
|---|---|
| Gas 6.4L Hemi SRW - rear | ~80 PSI (owner-reported) |
| Diesel 6.7L Cummins SRW - front | ~80 PSI (owner-reported) |
| Diesel 6.7L Cummins SRW - rear | ~65 PSI (owner-reported) |
| Dually (DRW), any engine | Not corroborated - check placard |
| Overall range across sources | 60-80 PSI (varies by config) |
| Authoritative source | Driver's door placard / owner's manual |

Frequently asked questions
Is Ram 2500 tire pressure the same for gas and diesel trucks?
No. Owner-reported placards show gas (6.4L Hemi) single-rear-wheel trucks commonly around 60 PSI front / 80 PSI rear, while Cummins diesel single-rear-wheel trucks commonly run around 80 PSI front / 65 PSI rear. The diesel engine's extra front weight is the main reason the front figure is higher on diesel trucks.
Where do I find the correct tire pressure for my specific Ram 2500?
Open the driver's door and look at the placard on the door edge or B-pillar, or check the tire and loading information page in your owner's manual. This placard is set for your truck's exact engine, tire size, and axle configuration, so it overrides any general number you read online.
What is the tire pressure for a dually (DRW) Ram 2500?
We could not confirm a specific, reliable PSI figure for dual-rear-wheel Ram 2500 trucks from available sources. DRW trucks use a different tire size and load rating than SRW trucks, so check your own door placard rather than assuming an SRW figure applies.
Should I use the door placard PSI or the maximum PSI molded on the tire sidewall?
Use the door placard (or owner's manual) figure for normal driving - it reflects the vehicle manufacturer's ride and handling calibration. The number molded on the tire sidewall is the tire's maximum cold pressure rating, not the recommended everyday setting, though heavily loaded or towing situations may call for pressures closer to that maximum per your owner's manual guidance.
