I purchased this set of tyres for my 7 year old sons Arrma outcast running 6S, he loves them. Unlike the T Apollo I bought for my kraton, the treads are still attached to the rims with no signs of separation. The tyres have a reasonable amount of traction during acceleration and steering when running the car on light gravel which is my sons favourite surface. I would consider purchasing another set in the future if needed. Thanks Paul.
