We know a tyre has a 100% life span and after practice runs we see something like this:

Use the figures you get as a rough guide to how long each tyre will last.
Rough estimate of a tyre
SS 100/12=8.3
S 100/6=16.6
M 100/4=25
H 100/3= 33.3
How much of the tyre you want to use in a stint is up to you.
H 60% roughly 20 laps
M 60% roughly 15 laps
S 60% roughly 10 laps
SS 60% roughly 5 laps
Remember this is all just Estimated Figures, you may find you could run more or less laps. Hope this gives you a rough idea, Good Luck and have Fun.
