ok i have been running nitto 555r's for a while...and they are part sponsor of my car....they are the best all around street tire i have used....they hook much harder on the street then the track.....and i wouldnt hesistate to use them in the rain they are great...i have the mt streets b4 and they are horrible in water and the street...but they are killers at the track......they also dont last as long as the nittos..even though with aggresive driving habits u will replace both brands within 4k miles.......but i would choose anyhing over the 555r for the street anyday
