tire pressure

[it's a dogs life]

Just a heads up, if you have the 21 inch, 40 series tires, make sure you check the tire pressure. My previous vehicle had 65 series tires; a 10-degree temperature change would change the tire pressure by about 1 psi. These 40 series tires seem to change about 3 psi with a 10-degree temperature change.

The 19s might be worse. I've seen at 5+ PSI difference...of course that's with about a 30 degree (Celsius) temperature change.

The first serious cold snap here, set off my tire warning system. It showed a picture of the car with the low tire blinking so I knew exactly which tire was low and while I was at it, I checked the rest and corrected all to the exact psi recommend.

Had to go driving for a short spell to get the warning to shut off, which is normal.

I also left the tire pressure page showing it sure does take a while to heat up the tires when it’s cold. Be careful when you’re driving because that rubber is hard as a rock and it does not grip for aggressive turns or entering on/off ramps etc.. Make sure your tires are up to temp before playing aggressively.
