Hey All,

Newbie here and just purchased a 2019 Jeep Sahara JL and the tire pressure light came on. What is the ideal tire pressure?

Thank you!

Mikey,

If it's stock, the factory recommended (cold) tire pressure is on the sticker on the B piller of the driver's side door. Should likely be 36 or 37 psi.

However, depending on the tire, many like the ride of their Jeeps at about 32 psi.

Mikey,

If you really want to get technical, you can perform the classic chalk test. This let's you know the best possible 'on-road' tire pressure for your tires on your particular Jeep.

Draw a straight line of chalk across the entire width of your tire and drive a few hundred feet or so. If the chalk line wears evenly, the tire pressure is optimal.

If the chalk is worn more on the outside, your tires are under inflated. If the chalk is worn only on the inside middle, your tires are over inflated.

However, the best pressure is where your Jeep drives and feels 'right' for you.

Experiment a little. You'll find your sweet spot.

However, the lower psi you go the better chance you'll trip your TPMS warnings. But there are ways to suppress that if you are really comfortable at a lower pressure.

Just ask if this is a concern. Typically a third-party programmer like the Tazer is a popular way to lower TPMS thresholds.

Stock or not I highly recommend chalk testing your current setup, you will be surprised on how under or over you should be running.

I see you're in Chicago - with all the recent changes in temps, I'm going to guess that the recent drop triggered your warning. On my Jeep (and the Sahara prior) sometimes just leaving the garage in the morning and leaving the car at work outside would trigger the warning. With all that, I'd also go to the low range in the winter and up the pressure in the summer or for long highway drives.
