Re: tire pressure
I agree with goalie. Keep your tires at the recommend pressure because the pressure fluctuates as you drive. The pressure in your tires increases as they warm up or as drive to a lower elevation. I have had my TPM light come on when it is cold and then go off when the tire warms up, I also had it come on a drive to Tahoe. I don't recommend relying on the TPM, check your tire pressure regularly.
