Tires that are over inflated are just as bad as those that are under inflated. The 10 PSI is a little bit old school tire with high sidewalls. I can't say what the best tire pressure would be, but I would adjust it in the Autocross environment, so that the wear is just to the outer edge of the tread. The GY's probably won't get warm enough in that environment due to the short runs. The higher the pressure the cooler the tire will run.
