16-month old Paradigm 385FL - We had an interesting situation develop with 1 tire: losing about 10 PSI a day. Examined the tire for typical reasons, including the sidewall and tire bead seal with no obvious culprits. Decided to check the metal valve stem - barely more than finger tight.
From the interweb, Tirereview.com, “…aluminum wheel valve stems present definite problems when they are improperly torqued. If the valve stem is loose, the assembly leaks. If it is too tight, corrosion will begin to form around the valve stem and a leak will soon follow. The recommended torque for standard aluminum wheel valve stems is 7 to 11 ft/lbs or 80 to 125 in/lbs.”
Another lesson learned and now part of my maintenance checks.
