I had my tires filled and tried to check the pressure. Even with the valve stem at 12 0'clock I got wet. It turns out one tire was over filled. I simply took the hose off a hand pump, attached it to the valve stem and drained about a gallon of fluid into a pail. Now both tires can be checked and adjusted 'dry'. I leave the gallon in my unheated garage in a container and shake it on cold winter days to see if it is getting slushy. Also, I used a cheap pressure gauge that first time - glad I did not fill my digital gauge with antifreeze.
