For street driving I don't really care what I run on...id probably pick PSS because they lasted longer. RE71 turned much faster lap time on track but the PSS still had unbelievable grip for being something like a 300 tread wear tire. The RE71 lasted about half the track days that the PSS lasted. RE71 had pretty good grip all the way to the cords, whereas the PSS heat cycled out after about 8-10 track days.
