Got a tire pressure alert as pressure had dropped to ~28 PSI. So I inflated to where I typically keep them, at ~32 PSI. But now I'm still seeing the alerts, despite pressure being essentially normal. First I've experienced this, Has anyone else seen this?
I have a dealer appt. this week to check this in addition to a couple other things.

Reset your TPMS system. This should allow it to read normal at current pressure settings. Normally rears are run higher than 32. Check your sticker on b pillar or on fuel flap.

I reset mine at 32psi (which is what was recommended), at what pressure will it now notify me?

Of course, the pressure recommendations on the B pillar are different from those on the fuel flap as discussed ad infinitum in this forum and elsewhere. I recently replaced my prematurely worn run-flat Pirellis with non-run-flat Michelins, which resulted in a better ride and higher long-trip gas mileage (+2 to 3 mpg). SUVs run at 32 to 42 psi tire pressure depending on various conditions, especially cargo load. Although the RF Pirellis gave a somewhat better ride at 32 psi (stiff side wall), I'm finding that the standard Michelins provide an ideal ride and optimum gas mileage at the dealer recommended 37 psi all around.

When I leased my daughter her GLC - I replaced the Extended Mobility Tires 1st week - replaced with "standard" upgraded Yokohama's - frankly smoother and better handling - and I threw the "originals" in the garage to put back on at lease turn in. The Yoko's will run out to 30K miles no problem - and no worn charge backs at lease end. I "think" I would go thru 2 sets Extended Mobility versus I "think" I will go thru 1 set "standard" before turn in. I put the Mercedes "jack kit" in the trunk - with a can of Fix-A-Flat - and she has Mercedes Roadside anyway...

I have a personal problem with the Extended Mobility - the manner I drive - the stiffer side walls aren't flexible is turns-at-speed - "push back" so to speak - the Yoko's (or Michelins, or whatever) "standard" tires eliminate that "push back" feeling - so just for that it's worth the change out for me.

All good points, fabbrisd1. I think it's also worth noting here that Michelin has "3-Year Flat Tire Changing Assistance" including tow service to the nearest Michelin dealer for up to 150 miles at no charge.

This sounds like the way to go. So I assume there are no warranty compromising issues by not using OEM tires?

Also worth noting that you need to drive the vehicle for a few minutes after changing the pressures. The numbers will update in real time, but the warning light needs a mile or two of driving before it will go off.

Where is that available and it is on all Michelins
?

guido3

Literature included with my tires covers it. You might want to read on from here: https://www.michelinman.com/US/en/wh...mise-plan.html

That is welcome bit of information. I double checked with Michelin and there is no requirement that you need to have a spare on board.

I believe that you can set the baseline for the tire pressure, and if it falls below then the alarm goes off.

Ddmccormack

how do you set the baseline?

taphil

On tire pressure display, press Down Arrow button and OK to store baseline values and restart TPMS.
