Either it developed a leak, something is wrong with the valve, or some stoopid pig-fart kid decided to let out some air for giggles.
I inflated the tire today and I'll check it in a couple of days too see if it's leaking again. If so...New tube or valve. If not...the hunt will be on for some stoopid pig-fart kid. [IMG class=inlineimg]https://www.volusiariders.com/images/smilies/icon_mad.gif[/IMG]
I inflated the tire, waited a few days and took another reading. No air loss.
Unless there's some other reason I can't think of, I better start checking my air pressure before every ride until I catch and scare the hell out of some kid.
It'll be fun.
I don't need a compass to know which way the wind shines. Pray, Hope, and Don't Worry.
