I'm in the process of changing my IT-B Pinto over to a hill climb racer. I just bought 6 Hankook 225/45/13 C50 tires and I would like to know if they have any thing I should know to run them. Wheels are 13X7" and the car weighs 2375 lbs with a locked rear end. Tire pressure to start with? Thanks and come see me at the "tail of the dragon"
