I have the tire valve stem at 12 when I let the air out down to 20psi, but calcium still come's out, why does it still come out if the stem is at the top?, is letting air out of the tire acting like a syphon hose, and will drain out to much calcium?, I don't get it big Dan.
But at 20 psi, the tire's still seam to hard, at 8 ply with hauling a log, the tire's should still squat a little, I don't like the rear tire's that hard, I like some give to them when I go over stumps and rocks hauling out logs. I have 2 air gauges, within 4lbs. of each other, and one for RimGaurd, is keep checking calcium loaded tire's gonna ruin my gauges?
