Serious racers, listen up! These NITTO NT555RII radial tires are absolute beasts for auto cross competitions and road races. The P275/60R15 size with 107W load rating features a unique fusion of Nitto's drag radial tread pattern with stiff sidewalls specifically designed for racing performance. The tread design includes twin center ribs that maintain consistent surface contact at all times, giving you enhanced stability when you need it most. Those large tread blocks provide optimal surface contact for better cornering and serious traction off the line. The soft racing tread compound is formulated for warmer weather and competition use, giving you enhanced control and handling even in extreme racing conditions. These are D.O.T. approved so you can run them legally, but they're definitely built for performance first. The black sidewall looks mean and aggressive, perfect for showing off at the track. Nitto recommends using these on your drive axle while pairing them with NT555G2 tires on the non-drive axle for optimal performance. Whether you're hitting the drag strip or tearing up road courses, these tires deliver the grip and stability that can shave seconds off your lap times. The quality construction means they can handle the abuse of competitive racing while maintaining consistent performance. If you're tired of spinning your wheels when you launch or losing grip in corners, these NT555RII tires are exactly what your build needs to reach its full potential.
