I haven't had these tires off the rims yet. Are there actual pressure sensors on the M2?
I suppose i could let a few PSI out of one tire and reset to see what happens to the display? |
That's weird, it definitley measures the pressure. I over inflate my winter tires by 3 PSI and when I do a reset it's reads the correct PSI. Did you by any chance inflate your tires when it was hot out and then did the reset in the morning or on a day when it was cooler outside?
