Well, the game has changed a bit over the last year, Tyres got an update. I've only been a member since Feb or March but the summer was hard on the tyres. I always look at the temp of the track in race prep. If it's above 25C and a high wear track, you'd be lucky to get Softs to do the whole race if your stints are longer than 11 laps. I've not used Med tyres for race in some time. Right now I'm putting on softer tyres than my Tech Dir says but I'm also doing 3 stoppers more than I did before and also attending the races and managing the push levels too. otherwise tyres go too cold or too hot.
