So a Harley washed up on shore on the west coast. How long before a kei truck lands?? Might happen if it were on balloon tires. Ask about our next project in the works……flotation tires on a mini truck. Our goal is not really to make it amphibious, (but it would be awesome) but to leave the lightest footprint possible. Already our trucks with tracks installed have a footprint of .583 psi but we think we can come close to that with tires, a couple of us even believe it WILL FLOAT.
