| do harder compund tyre's give beter top speed? or even higher pressure? since there would be less friction with the ground if inflated highly. and would it not matter one what kind of floor your riding on? and if its wet or dry? or a cold or warm track? do any of you serious racers change tyres depending on the track layout, condition, tempreture or any other reasons?
im only running the tyres that came with my bike but i dont know if there properly round, i dont race because we dont have a track around where i live so i guess my standard tyres will do lol
