Lee The replacement for the NRW is the RW. I just bought a set of 225/45-17s and drove about a 1000miles to attend the ACNA Nationals at Sears Point this week. They replaced a set of NRWs in the same size. On this trip my wife and I encountered every kind of weather imaginable. They performed outstandingly. Hap, feelin the boost at sea level, Maguire
