What is the right tire pressure for a Jeep Grand Cherokee?

Generally speaking, your Jeep Grand Cherokee’s tire pressure—for both the rear and front wheels—should fall somewhere between 33 and 36 psi. Your owner’s manual or the sticker on the front passenger-side door can give you a more specific recommendation based on the vehicle model year, trim level, and the size of your Jeep’s wheels.

It should be noted, however, that your tire pressure may fall outside of this range if—like many Jeep Grand Cherokee owners—you install larger and/or all-terrain wheels and tires, so be sure to check the exact pressure specifications whenever you diverge from the factory-issued equipment.

Low tire pressure in cold weather, and how to fix it

How to check Jeep Grand Cherokee tire pressure

If you own a newer Jeep Grand Cherokee, you may be able to electronically check your tire pressure via your Jeep’s dashboard or using the multimedia touchscreen. If your tire pressure monitoring system (TPMS) senses that you need to add air to one or more of your tires, the low tire pressure warning light on your dash will turn on.

You can, however, check your Grand Cherokee’s tire pressure manually with a tire pressure gauge—simply remove the valve stem cap on each tire and press the gauge onto the valve stem. After a few seconds, the gauge will provide a reading that you can then use to either add or remove air from the tire in question.

Your Jeep might also warn you of low tire pressure in more subtle ways, such as sloppy steering, an uneven ride, and reduced performance—all are possible symptoms of a tire pressure problem, so take the time to check that your tires are properly inflated if you begin experiencing any of them.

How often should you check your tire pressure?

Per expert recommendations, you should check your Jeep’s tire pressure at least once a month and before any long trips, taking care to use the same tire gauge every time to ensure consistency.

How to tell if your Jeep Grand Cherokee needs new tires

If you follow the manufacturer's recommendations, you should be replacing your Jeep Grand Cherokee’s tires every five to six years. Nevertheless, it's a good idea to regularly check your tires for symptoms of unusual or accelerated wear whenever you check your tire pressure. You’ll know it’s time to consider getting a replacement if you begin to notice strange bulges, cracks, or low tread depth in the tires.

The penny method is a simple way to check the tread depth of your tires—just insert any U.S. penny head-first into the tread. If you can see any of the former President's head, your tires need to be replaced.

How to reset the Jeep Grand Cherokee tire pressure monitoring system (TPMS) light

Once you correct the pressure issue in your Jeep’s tires and let the engine run for 15 to 20 minutes, the tire pressure monitoring system (TPMS) light on the dashboard should automatically switch off. If for whatever reason the warning light does not turn off, you can reset it yourself by following the steps listed below:

Turn your vehicle off and then switch the ignition to the “ON” position without actually starting the engine.

Find the TPMS reset button—which is usually positioned somewhere underneath the steering wheel—and hold it down for a few seconds until the TPMS light blinks three times.

Release the button, start your vehicle, and go for a drive—once you’ve covered between 10 to 15 miles or driven for roughly 20 minutes, the light should turn off.

If this method does not work, try disconnecting the battery, switching the ignition to the “ON” position without starting the engine, pressing the horn for a few seconds to drain the remaining power, and then reconnecting the battery.

In the event that the TPMS light still won’t shut off, you’ll need to take your Jeep to a mechanic and have them diagnose the issue for you.
