wheels that fit .

The foam wheels MIGHT be a bit of a cleanliness problem if you roll themthrough mud. they might absorb some of the mud and be a bit difficult to clean out. The smooth surface harder rubber untreaded style wheels would clean up easier.

Ihaven't done uch flying off mud... but fro the rusults off ice on blacktop... you probably won't see much difference no matter what wheel you use. (taildraggers a a pain on ice. the toe-in trick is useless then.)
