Same pressure for a similar MC tire. Might get away with a couple PSI less if you wanted. Do whatever you feel most comfortable with but I would keep it in the range of 38 to 43 psi. Might want to go to the lower side if you are starting out on a cold morning but expect to see temperatures in the 90's later on. Again, no different from what I would do with the stock 180.
Having once worked for Goodyear Tire and Rubber I can advise you to go to the higher cold tire pressure. If you under inflate a tire it will build up pressure much more than a correctly inflated tire. Friction is greater on under inflated tires and that translates to heat and higher PSI. I always use 42psi for rear 190/55 and 39psi in front tire. I ride one up at all times.
