Hey, last night the temp in toronto dipped down to -10 or lower and my tire pressure light came on. I checked the psi and it is showing 28 front tires and 27 back tires. I'm guessing because the weather is so cold that the tire lost pressure, so how much should the psi regularly be and how much air should i put in ?

thanks in advance

 

Should tell u on label when open driver door?
I believe it's sould be 35 PSI which trim model u have?

 

If it doesn't have stock tires, then refer to the sidewalls for proper psi for that particular tire.

 

34 all around for 18s, I believe.

 

Yep,

Bump that sucker up to about 35psi on each tire and drive around for 20 minutes, the light will go off.

 

Tire pressure (35 PSI) should always be checked cold. Usually in the morning before diving.
