hello guys, suppose you set all your tire psi to 40 in the morning, after tyre has sat overnight..... during driving, u know they rise differently but eventually all settle to any psi considering weather temperatures.

then next morning, when u set out... is it possible for any of the tires to be below 40 by + or - 1 or 2 , say 39 or 38.


is that normal or is there a leak, though i have check for puncture , rim leak, valve leak, everytin seems air tight.

thanks

I find that my hot temp and cold temp variation is usually + or - 3psi's. If it is cold and the temp reads 39, it usually warms up to 42 for me.

when it warms upto 42.......... and u park it overnight, does it drop to 38 or 37, or it always starts at 39?

Depending on how hot in the day it was when it registered as 42 and how cool it got at night, I've seen as low as 38. But the norm for me is usually a variation of 39-42. Keep in mind that tire pressure does diminish over time, that's why it's essential to regularly check your tire pressure.

ok coolie, i guess how cool it got at night is right, but i thought that would happen for all tyres, but in this case, only 2 on driver side will go lower than the other 2
