this has me wondering if i should pull the tubes out of my slicks.

the left rear goes flat in about 4 days and the right rear hasnt lost a lb.

could i use bead sealer to help seal the bead to the wheel, and then some silicone on the wheel screws to ensure no/ less leaks?

what would i use as far as a valve stem? would a regular(free) rubber one work from my job, or do i need a special one? which is prefered.

probably going to make the switch soon depending on answers!
