For the hard core H2 wheelers

[PARAGON]

I'm not liking them a whole lot. I can rattle can my wheels (and did) if they get scratched. I doubt you could leave them on all the time if you got into much mud since some mud would trap inside and cause an imbalance.

The main thing I would be worried about though is access to the valve stem. We have a tractor with wheel weights and it is a pain to fool with because it's hard to access the valve stem through the "hole" in the weights. But I haven't seen any in person.
