These tyres came with my RC kit. At first, I was impressed with their performance but it quickly deteriorated with everyday use.
Compared to other drift tyres which I have tried, these are quite grippy. This allows for high speed drifting, but you don't get as much angle. Also, due to the construction and shape of these tyres, they are best suited to smooth surfaces such as concrete or cement. They do not slide well on asphalt.
Though these tyres are more grippy than some, they are still great to use and lots of fun, especially when matched to a more powerful motor and well setup chassis.
