What is the right tire pressure for a Ram 1500?
For most Ram 1500s from 2019 or earlier, the recommended psi is 36 or 38 for both tires, or 55 for the front and 45 for the rear tires. Some models from 2015 to 2018 might also have tires with a recommended psi in the 40s.
There are several tire and wheel options available on the Ram 1500, so make sure to consult the sticker on the driver’s side door jamb for the correct figures for your truck. In addition to that, if you have swapped out the original tires for different ones (like all-terrain tires), the psi could be different as well. Make sure to get the correct recommended psi for your specific tires.
PRO TIP: The number that you’ll find printed on a tire is the maximum psi, not the recommended one.

How to check Ram 1500 tire pressure
If your Ram is a newer one, you’ll likely have a tire pressure monitor system (TPMS) that will display your tire pressure and let you know via a warning light if any of them needs air. But if you have an older Ram 1500 or one that doesn’t have that option, you can easily check the pressure yourself. And honestly, it’s a good thing to be able to do no matter what—you never know what circumstances might arise.
The gauge will indicate your tire pressure, and then you’ll know if you need to add or remove air.
Ideally, you want to check your tire pressure when the tires are cold, which means that it’s been three hours or more since your truck has been driven. Of course, this may not always be possible in the real world, but it’s a good factoid to know.
In addition to an alert from your TPMS, you may see some indications that your tire pressure needs attention by the way your truck is driving. An uneven ride or handling, weird steering, or a decrease in performance all warrant a tire check.
How often should you check tire pressure?
Check your tire pressure at least once a month, and always before setting out on any long trips.
How to tell if your Ram 1500 needs new tires
Consumer Reports recommends that you get new tires about every six years, but this can have some wiggle room depending on where and how much you drive. It’s a great idea to get in the habit of checking your tires for wear at the same time you check their pressure every month! Look for strange cracks, bulges, bald spots, or low tread depth.
Tires all have tread wear indicator bars located between the grooves, and these indicate the point at which the tread is too low. Another easy way to check is the penny method—grab a U.S. penny from your change cup and place it so that President Lincoln is head-first in the tire groove. Can you see the top of his noggin? If so, it’s time for new tires. Honest Abe wouldn’t lie to you!
Resetting the Ram 1500 tire pressure monitoring system (TPMS) light
The owner’s manual states that once you fill the tires to the correct pressure, the TPMS light should go off, but that you may need to drive above 15 mph for about 20 minutes first. But if you’ve done that and the light’s still on, you might need to
reset your TPMS.
Consult your owner’s manual for details, but here’s the condensed version:
- Drive for 10 minutes at 50 mph, then park and shut your truck completely off.
- Turn your key to the “on” position, but don’t restart the engine.
- Press and hold the TPMS button (usually under the steering wheel) until the light blinks three times.
- Release the button, start your truck, and drive for 20 minutes to reset the sensor.
If this doesn’t do the trick, you may have a problem with the sensor itself. Bring your Ram 1500 to your dealership or mechanic for further assistance.
