  
 The Nitto NT555RII “Extreme R” D.O.T. approved road race and auto cross competition radial tire was developed through a unique fusion between a race circuit oriented stiff sidewall construction and the popular Nitto Drag Radial tread pattern. These features combined with the high traction, specially formulated soft racing tread compound resulted in a competition radial that exhibits impressive control and handling, to provide maximum traction under severe racing conditions. The sidewall construction is optimized for handling extreme lateral acceleration; vehicles may experience rougher riding when used for daily driving. The Nitto NT555RII is designed primarily for competition road racing.
