Disregard this whole post lol we didnt run radial tires................I suppose you would also have to consider expansion rates, the car in my avatar (2450 lbs) we would run 8 psi in the tires but after an 8 lap heat race (3/8 mile track) the pressure increase was 3-4 psi, a huge diff in handling characteristics, perhaps even a contributor to the T's fishy front ends. surely there is disproportional expansion on a street tire as heat builds up? Of course if you air with nitrogen, no worries
