Lots of talk lately about C/T use and what psi we all like to use in them. Here is an interesting list of just that and look for the column that has the "sweet spot" psi, some of the Valkyrie models/tires are mixed in with the Goldwing so scroll down carefully. Personally I like 36psi in the ATT and 40psi in the Yoko Avid Envigor. I am surprised to see these other bikes experimenting the D/S.
