Im pretty new at this so would really appreciate your help on the matter below: 
  Ive searched all over internet-land to find a standard starting point for tyre psi when I arrive at new circuit with my recently purchased pro kart & ive had no joy - I know the tyre pressures I should run will vary from one circuit to another but where would a good standard starting point be? 
  ____psi Front ____psi Rear etc… 
  I know I shouldn’t change the front pressures but im not exactly sure what psi I should be running them at to start with? Other than increasing psi to overcome understear & decreasing to help with overstear, im pretty lost. 
  Many thanks in advance. 
  David
