Tire low message

[LucidDriverPodcast]

Hello. I have been receiving a persistent low pressure warning on my front Driver side tire but all the psi’s are the same. The weather is 80’s to 60’s each day. Any ideas? Thx

Received this the other day in my right rear tire. Pretty sure the display is rounding the pressure, so your front driver side is probably a bit lower, triggering the warning.

The change in temperatures at this time of year can cause some issues for those of us trying to keep tire pressure optimal. I found the Lucid TPMS pretty accurate, but you may want to check the pressure "manually" and top off as necessary. Keep in mind that the outside temperature is going to affect your pressure. Always check your pressure when cold (not after driving).

If all your tires are the same pressure, it sounds like all of your tires need some adjustment. 19" A/S should be at 49 PSI.

I am having the same issue but they are all reading the same.

What size wheel?

19. Specs say 45 psi. Just added air Sunday. They all show 44 but front driver says it is low.

Where did you get 45? The cold inflation pressure for 19s is 49 PSI.

The 20s and 21s range from 42-45 PSI depending on speed (above 155mph it should be 45psi cold).

The 19s are 49 PSI, always.

tl;dr: your tire pressures are all too low. The reason only one shows an alert is because it’s a couple decimal points lower than the others, so it might be just on the cusp of too low. (43.8 vs 44.4, for example)

With the first low temps down to freezing in Michigan last night we experienced our first tire warning since taking possession of our 2026 GT on October 1st. All of the tires were down to 44 or 45 psi. As noted previously with the 19" Aero Range wheels the door sticker states 49psi for all tires. I was also wondering if anyone uses extensions on the tire valves for ease of inflating?

I've got the same question - first cold weather with my Air. Do I need an extension to reach the tire valve or is there an easy way to get the air hose over the wheel covers? Thanks!

You can just pop out the one section of the cover over the valve stem (about an inch) and get to the stem without taking the cover all the way off
