I drive a machine with 6 wheels. It can drive really well on 4 so I have two spares at all times. It can probably run on 3 if I sit in the right spot.
Went on a particularily nasty trail in the Avenger and came back on 2 tires with air, the other 6 were flat from either sidewall cuts or bead breaking.
Would you like to have a set of wheels that will hold a bead even with a flat tire? Matt Oxender's wheels are identical to bigfoot/avenger wheels, only they are designed like argo's should have been. You can contact him through his user name here on the board.
