I think this is a great topic. I came from running stock cars before karts so treads is what i know. I run a UAS kart wich makes it a bit different then a stocker but I still get the same answer. "oh slicks will always beat a treaded tire" Here is my view on it and I have not tried treads but I will this year. I always feel people are just saying that slicks are faster because thats what they here, or thats what they are told. Does anyone have facts? Has anyone done lefit testing? I dont mean some saturday night guy testing either. I mean guys along the lines of Mullis, Knoff, or any other guys that win alot on there own tire actually tried to prep up a tread and see the difference? Has hoosier tire done a study from there tread to there slick? I can say a wooden wheel is faster then a slick and if im a good enough salesmen and spread the word enough before long people will be on wooden wheels. I cant say one way or another wich is faster but someone in this world has to have proven facts on paper that can be shared. Look at sprint karts (yes they have more power then a clone or flatty) but they are all on treads. Dont you think if slicks are faster they too would be on them? Idk the answer but its always a good conversation.
