Here is a link to some tires I bought -
http://cgi.ebay.com/NEW-Lot-of-4-Mountain-Board-Skateboard-1...
If the link doesn't work, just do a search for 'mountain board' and you'll see the tires there. You won't be using the rims or bearings but just the
tires and tubes. If your MBS board has existing rims that support the 9" tires, then they will work.
Just remember, you're not going to be able to ride on really soft sand. They sand has to be somewhat hard packed. For soft sand, you'll need a buggy
and 'bigfoot' tires.
