ok...but carol smith doesn't advocate the use of a pyro at all. From what I remember, he prefers to "read" the tyre and let the stop watch tell the story, thats why I was asking. He doesn't like pyros and I don't agree with this reading the tyre temp across the tread because you have one other factor which affects the reading, which is carcass construction. Tread foot prints can distort under load and give a really poor reading across the tread. Changing the tyre pressures doesn't fix a construction problem.
I also have found that the pressure increase for 'air' is about twice that for 'nitrogen' filled tyres i.e. air filled will increase by say 12 psi while the nitrogen filled tyre will increase by 6 psi.
