sand gecko's

probably worth $40 if you can;t find anything else cheap... they really are a pretty crappy dune tire though...
 
Geckos rock for Blasters. They won't turn haulers as well in the sand. You need at least some wheelspin. I loved my Geckos on my Blaster, they handled real well and they still had enough bite to do wheelies and make it up some gnarly hills.
 
you just gotta get the right hauler... an 8 pdl is not the right hauler..
 
i liked my geckos, they were pretty okay for traction and still gave you some good handling.. but if you take them out of the sand they will wear down quickly
