Has anyone else experienced this before? Seems odd that it’s only identifying one tire that’s below 55 psi.

I think the alert pressure may be adjustable. I don't know why your pressure is that high. My truck calls for 36 PSI all 4 corners. Do you have some strange tires, with a Rebel, that take different pressures. I've only seen that on HD trucks.

Yeah mine is a Rebel so that's why the PSI threshold is that high.

Door sticker says:
Front= 55 psi
Rear= 45 psi
Front= 55 psi
Rear= 45 psi

In that case, there is a limit, when it notifies you. They don't notify, until it crosses that line. The left front is the only one low enough for notification. I think my limited notifies at 6, but due to your higher pressures, Rebels may not notify until 9.

Your front psi thresholds are set for 55, and the rears are set for 45. The low tire warning sets at 20% below those thresholds.
What you see on your screen means that, at some point, the front left tire fell below 44 to trigger the low tire warning, then raised back up a few pounds with heat expansion. When this happens, you have to air it all the way back to 55 to get the low tire warning to go out, then you can air back down to where you want to be.

Exactly what Jimmy07 stated. Once air pressure goes below the threshold you get a warning in red, usually during cold temperatures (it dips more than usual, then jumps back up as it gets warmer), the red warning will not go away until you inflate that tire all the way to full, in this case 55.
The other tires maybe below that, but they didn't fall below the warning threshold, so they aren't red. Once you hit 55 on the red one, the warning will go away and wont come back until you go below the threshold again. You can then drop the pressures again below 55/45 if you prefer, but good idea to set them on a cold day so they don't fluctuate too much below that and set off the warning again.
