Hello, from 0.5 to 3.1, you must use tire I, if the rain exceeds 3.1 use W.
I would disagree to a point. Inters work just as well as Wets up to 3.3mm. You have to use a bit of Kers to bring them to temp, but once there, they hold just fine at 75% push. Maybe this is Track\Temp based? Tire wear based?
I used this in Austria this season. Everyone went to Wets, as it was on the border I stayed Inters. I pushed about 20%, give or take, of Kers & the tires ran the rest of the stint just fine.I switched to Wets on the last stop & had to run one off of the bottom on the push bar, so they wouldn't over heat. Times where close to the same.
