Post Body

I've got a Helio C2 with newton gravity wheels. Somewhere I saw a claim that they are "universal" and can use both pneumatic and urethane tires. I live in a city with abysmal road/sidewalk conditions, I'm approaching a snowy winter, and my tread is nonexistent. So they must be replaced. Currently I have urethane tires, but I've been thinking about switching to pneumatic for the claims that it's a smoother ride. But I can't find a hole for an air valve anywhere, so I'm not even sure they would be compatible.

These are the current tires.

Can my wheels actually use pneumatic tires?
