Team 100 has used the 6.75"(?) skyway pneumatic knobbies since 2002 with great success.

I would definitely reccomend talking to Skyway to see what theyr'e offering specifically for FIRST use before you look elsewhere.

If you have access to a lathe, you can take the kit wheels and lathe the tread material off until it's flat, and then attach belting to them for added traction.
