Last summer we picked up a set of Michelin X-Ice mounted on new wheels from Tire Rack, and tucked them away in the garage until the snow fell this year for use on our 2025 GT.
First problem when I went to put them on the car was that Tire Rack had sent a set of lug nuts for the wrong stud size! But who needs a second set of lug nuts really so that was easily remedied. The second, though, was that the TPMS never learned the new sensors. We drove about 200 miles the next day; it never picked them up; I got home, ran the manual relearn, took the left front tire all the way down to 25 PSI and it never picked it up. Tried a 315MHz Ford sensor actvation tool; no luck.
I called Tire Rack back and we agreed they'd probably installed the wrong sensors along with sending the wrong lug nuts. They sent a new set, which are Schrader part 20452. Yesterday I finally found my BeadBuster, broke the bead on the right front tire (easiest one to get at with the car in my garage), and was surprised to see that the installed sensor was a...Schrader 20452.
Now I'm a little baffled. I fired up Forscan and see DTCs for both sensor signal failure and TPMS system fault, but they won't clear (or won't stay cleared, hard to tell). Maybe the Schrader sensors installed in the wheels are bad, or maybe it's my bad luck and just the left front, which goes first in the retrain procedure, is bad or the wrong part? It's a little hard to confirm but the 20452 does look like one of several 315Mhz Schrader sensors that should work in this application.
I don't really trust tire shops to lift my Mach E without damaging the battery rail but I guess maybe next step is to take it in to one and let them see what they can do - at least they should be able to read the sensors through the tire with their tool, right? That tool is a little pricy for me.
There was no TPMS issue at all with the stock tires/wheels.
Any suggestions?
