I am about to try a set of Nitto 555RII tires come Monday at the BIR 2.5 mile track. Any suggestions for me on tire pressure that anyone has? I have been running Conti takeoffs all summer and going to give these a try. The Conti's I have been running cold at 22 right side and 23.5 left side and that seems to be working very well due to the predominant right turns on the track. Any suggestions for the Nittos??
