I just got rid of my nittos because they were bald! I love em!! They are a better street tire then my Sumotomos!! They have an actual tread,so they are great in the rain.At the track it was weird,you had to heat them up just rite,or they would spin. I got a new pair of Hoosier quick time pros,Ive only had them on for a few days so I cant give you much feed back on them.When its dry out they seem to handle fine!! I havent drivin them yet in the rain yet.When I get to the track this weekend,I am sure they will blow the nittos away for drag racing.There pretty much a real slick,they have the same rubber compound as a slick.BUT,,the nittos last a lot longer then the rest of the DR's.After these Im going with the ET-streets,or the new et-street radials,not sure yet.
