Simple green works well to clean and get the tires nice sticky. Most the time its all I use with the treaded tires. But I use it full strength. As for the slicks it does get them sticky but not enough for my liking. But I still use it to clean them but have a tire sauce mixed for me by a friend. I think its a mix of AT fluid, power steering fluid, and something else. But man it works well. Granted we run on asphalt outdoors, carpet tracks may not like this mix though.
