RAM 2500 Tire Pressure
Most RAM 2500 models use 60–75 PSI in the front and 60–80 PSI in the rear, depending on model year and tire size.
Recommended Tire Pressure (Cold)
Always check on cold tires (parked 3+ hours). Verify on driver-side door jamb sticker.

Tire Pressure by Tire Size
| Tire Size | Front PSI | Rear PSI |
|---|---|---|
| LT285/70R17 | 60 | 65 |
| LT275/70R18 | 60 | 60 |

How to Reset the TPMS Light on a RAM 2500
- Inflate all four tires to the recommended cold PSI (shown above and on the driver-side door jamb sticker).
- Drive the vehicle above 25 mph for at least 10 minutes. The TPMS receiver typically re-learns the sensor pressure during this drive cycle.
- If the light remains on, with the vehicle parked and the ignition ON (engine off), locate the TPMS reset button — on most RAM 2500 models it is below the steering wheel or inside the glove box.
- Press and hold the TPMS reset button until the tire pressure indicator blinks three times, then release.
- Start the engine and wait a few minutes for the new baseline pressure to register.
If the light returns after a reset, re-check cold PSI on all four tires plus the spare, then inspect for a slow leak. Persistent warnings usually mean a faulty TPMS sensor (typical replacement cost: $50–$100 per wheel at an independent shop).
Frequently Asked Questions
What is the recommended tire pressure for a RAM 2500?
The recommended cold tire pressure for the RAM 2500 varies by model year and tire size. Front PSI ranges from 60 to 75, and rear PSI ranges from 60 to 80, measured cold. Check the year table below for your specific model year, then verify against the driver-side door jamb sticker.
How do I reset the TPMS light on a RAM 2500?
After inflating to the recommended PSI, drive above 25 mph for 10+ minutes. If the light stays on, locate the TPMS reset button (typically below the steering wheel) and hold it until the indicator blinks three times. The receiver usually re-registers the new baseline on the next drive cycle.
Does the RAM 2500 have a separate tire pressure for a performance or hybrid trim?
Yes — some RAM 2500 configurations use different PSI values depending on tire size. The table above lists every distinct pressure. Owners of performance or hybrid trims should pay extra attention to even wear and re-check pressure weekly, since the wider or specialized footprint is more sensitive to pressure loss.
Why does my RAM 2500 tire pressure read higher than 75 PSI after driving?
Driving heats the tires and raises the PSI reading by 2–4 PSI. The 75 PSI recommendation is a cold pressure measured before driving or after at least 3 hours parked. Never deflate to 75 PSI after driving — you'll end up under-inflated once the tires cool.
What happens if my RAM 2500 tire pressure is too low?
Under-inflated tires increase rolling resistance, reducing fuel efficiency by up to 3%. They wear faster on the outer edges, generate excess heat that can cause blowouts at highway speeds, and reduce braking and handling performance. If your TPMS warning light is on, check your tire pressure as soon as possible.
