BACK TIRE

imported post

Last night i thought the back tire was feeling a little funny, i went to check the air pressure in it and when i touched the vavle stem to unscrew the cap that caused a hiss of air pressure to come out around were the valve stem goes into the wheel, it still had 30 psi of air in the tire so i went home slow and easy, i will be haveing the valve stem changed out tonight, i do check the air on a regular basis, and until last night the valve stem seemed fine and i hardly ever have to add air, it was fine on sundays ride and just that fast started to leak, so check the air in the tires often you never know, look at those valve stems
