it will still leak, try putting in a new valve in the tube

just sounds like bad luck. try getting a different brand tube.

It may not be the valve stem itself leaking but air coming out of the valve stem. Your rims can get metal spines after tire changes that can pop your tube from the inside or if your spokes are lose they can puncture a tire from the inside also. Take the tire off and look inside for anything that could be poping them and check your spokes as well. You have that rubber protector on the inside of your rim to keep the spokes away from your tube and I always wrap some duct tape or electrical tape around that to make sure they dont poke through.

:applause: thanks guys great advice will try it out.
