I picked up a new inner tube to fix this flat tire. But there's a big rubbery type plug around the valve stem.
I've changed bicycle inner tubes before, but I've never seen a tire with this rubber plug. How are these tubes replaced?
Or is the tire considered a "tubeless" one. Maybe I should have picked up a bottle of that green slimey sealer instead.

So far so good. I replaced the stem core (cost $2) last night and this morning the tire still had air. We'll see how long it holds up.
