Awww, c'mon asd, that's too difficult to answer specifically.
For what "I" might call a medium traction track
, assuming GRP rubber, start with 42 fronts and 37 rear.
However, you will have been astute enough to have brought some harder and softer ones with you, 'cos the traction will commonly change as the day progresses.
