Just an interesting suggestion!!!!
After a Tyre reaches a given % wear in a race, there should be a chance that that Tyre would suffer a puncture, hence slowing down the car, but allowing the car return to the pits for an unscheduled pit stop.
The chance should be completely and totally random, but should increase in possibility as the Tyre wear increases above say 60% (or below 40%).
It would add an extra risk to the game, putting long strategies on softer Tyre's.
Any opinions on this suggestion out there?
