Use shoe polish on the tires to guage tire preasures if you don't have a temp gauge. Mark the tire with the show polish starting at the rim...Accross the side wall until you reach the tread of the tire (about 1 or 2 inches in).
When you do your first lap...if the shoe polish wears out all the way to the sidewall of the tire then you don't have anough air preasure. If it does not wear enough (some tread still has shoe polish) then you will need to take out a little bit of air until you get it just right.
