For all the rain you sun worshipers are getting right now, you might as well fill your tires with water. Should help weigh the car down more.

 

FWIW last night I checked all four tires using an Accutire digital gauge, 33.7 front and 39.7 rear both sides read the same. Inside temp in the garage probably 74. This morning when I started the car I was reading 33/40, the fronts then went to 34 in about a mile. By the end of my trip (20 miles) the readings had settled at 36/43 although they would go up and down as I drove.

I have never had a warning but I watch the pressures closely. I wonder at what point the TPMS goes to a higher number, i.e. if I had 33.8 cold in the front would it read 34?
