Hey.
I usually set a strategy in case I can't be online for the race. I always assume conditions will be dry. But let's say a few minutes before the race the track is wet and I wanna change my initial... how do you call it? Each combination of tyres+fuel you use between pitstops? Sorry, I'm not an English speaker. Anyway, how minutes before the race must I change tyres and/or fuel before they're 'locked'?
Cheers.
