I see. Whenever you lose some psi- Does it triggers the "low tire pressure" warning on the dash? I guess its normal to lose air pressure over time?
I only can bring my car on a Saturday Morning to a tire shop as over here- Friday- most business are close. I wonder if its ok to drive around a bit tomorrow with the "low tire pressure" warning on the dash? My car is nitrogen filled from the factory. Tires looks OK.
i got the LOW TIRE PRESSURE message last week, turns out i had a screw in my right rear tire and it was leaking air slowly. BTW, don't wait for the warning message, my deflating tire was down to 20 psi when i got the warning from the TPMS. Not knowing what was wrong, i inflated the tire and checked it again a few days later.... down to 24 psi and no warning.
So my guess is that the TPMS warns the driver at around 20psi, wich is way too low already. Tire pressure must be checked regularly for safety
