Here's how I strapped the tires to prevent ballooning.. not tested yet, but I'll find out how it works later today.

you need:
tires, foams, and rims
roll of fiberglass tape
big tube of shoe-goo
piece of scrap plastic

wash the tires in warm soapy water first, flip the tires inside out, then wrap a piece of fiberglass tape around the tire. I wrapped the tires twice around.



Run a very heavy bead of shoe-goo around the tire. the more goo the better. (I ended up making the bead about 3x as what's in the picture)


Use a scrap piece of plastic to spread the shoe-goo, and push it into the tape's square holes.



After the goo's dried, flip the tires right side out, put the foam back in, and glue em to your rims.



the end. I'll let you guys know how it works when I get done racing.
