Front - Max Grip for your tires (measured with pyrometer or shoe polish)

I don't want to jack your thread, but how do you measure grip with shoe polish?

Draw 3 equidistant lines through the tire's "shoulder", from the sidewall to the tread. After your run, you will see how far your tires are rolling over by how much shoe polish is worn away. If it's past the shoulder and onto the sidewall, then your tire is rolling over too much and you need to add air. If it's still present past the shoulder onto the tread then you have too much. If it lines up right where the tread and sidewall meet then you are getting the most traction out of your tire, as it's using the most possible tread in hard corners.

oh I see, I always use chalk for that. I thought that may have been what you meant, but I wasn't sure.
