Where can I find a set of tires for my Grizzly? I need them to fit on 12" rims. Should I get 2 or 4 tires? Any help is appreciated.

 

Realize I have no experience in this category, but I've got a couple of thoughts. (It sounds pretty cool to do BTW!) I'd think you might want paddles in the back and maybe decent mud tires up front? I think if you put paddles up front, you'd be swimming in sand as the front tires kick it all over the place, and probably the rider. If you got razors or smoothies up front you'd definitely loose any benefit of the 4x4 in the sand. Whatever you do I'll bet it'll be fun. I'm sure if you just ran on sand with mud tires you'ed be OK - I ride sand with MX tires and it goes pretty well.
