For awhile sometime ago this was a conversation that went in every direction . It seems that everyone has an opinion and it seems to vary all through the 30s but on Chy's recommendation I have been running 41 front and 42 rear and have found it to be just right in all conditions. Main thing I think is to keep it at what you decide is right for you because if it changes by much it seems like it starts cupping and you will need to replace prematurely. Keep it consistent
