The problem with the cast not fitting the tire turned out to be something we had overlooked. After examining 6 tires we concluded that the tires themselves where made up out of 2 half tires glued together.

This results in the profile not being aligned the same way on different tires, and therefore we aren't able to make a "one size fits all" mall.
After our first attempt on the tracks we where faced with a new set of challenges. In order to produce the tracks we would have to make about 100 tracks, which would take ages to cast, and a lot of rubber to produce. Also we would need to find a way to connect them to each other in a secure way.
Therefore we where forced to look at alternative designs.
