There is a new tire company out there and they are called panther tires they make t-maxx and 1/10 truck tires they currently have 2 t-maxx tires and 2 truck tires. the tires i tested was one of their truck tires the "switch" it works very wekk on hard packed clay tracks such as crcrc in columbus. i mounted the tires on 1/8 buggie rims to race on my mp-7.5 and i must say after they broke in i got faster and faster. they are definately a company to watchout for.
