Help with classifying my car?

[nando]

I saw a bunch of guys spraying down their tires between runs, what's the purpose of that?

I noticed that about halfway through the day, my tread blocks all had a gummy little ridge of rubber running along the outer edge.

to keep them cool - especially during hot weather. then there are the guys with foil blankets to keep heat in them, pyrometers, notepads, etc.

I would suggest starting out with chalk and a pressure gauge, try to set your pressure so you're not running over the sidewall, and check your pressure at the end of each run to keep it the same (you'll have to let some out).

You could always read the rules. But watch it, some of them are a bit tricky or archaic.
