Tire Pressure Monitor light came on

[rexxxlo]

i have had a small leak now for about 2 weeks
i have put the car in neutral and rolled it back in the driveway (dont worry its completely flat i wont get killed) and have found not a single thing besides very smal stones in the treads

no stuff in the side wall no screws or nails but it still comes on and i fill it back up i think the schrader valve or the tpms is leaking but haven't had a chance to check that yet

They tend to be overly sensitive in winter. Remember - as it is getting colder out, the pressure in your tires is going to decrease naturally. Mine has been coming on at random for about a week now (pressures are all in spec - I think the difference between a cold tire that has sat all night and one that has been driven on is confusing it).

Tires will loose air over time. Colder weather will affect the sealing on the bead and can make them loose a little more. Aluminum is a very porous metal and can leak air at times too. That is one of the reasons they started clear coating the Aluminum rims, and to prevent them from corroding.

Since we ALL check our tires weekly, it really shouldn't be an issue now should it????

One tire problem I had was a loose valve stem causing me to lose air without punctures.

I wouldn't want to worship there unless the sermons are extremely short and there's no singing.

did you use soapy water to check for leaks?

Put some dish soap mixed with water on the tire. put it in a spray bottle. the leak will bubble up the soap.

Mine came on last week. All 4 tires were 10 lbs under. I'm figuring the culprit is the spray I use to clean the wheels. Maybe some overspray got between the tire and the rim and created a slow leak. And thank got for that sticker on the driver side door. I was on hands and knees looking all over the tire for the PSI info.
