Here is what I am getting. I a practice session I'll go out and do 5 to 8 laps on new primes. I come back to the garage make a change or two go back out on the scrub Tyres and boom the car is suddenly super oversteer you to the point it is nearly 2 plus seconds slower. Same thing happens to me in the first stent of a Grand Prix. My question is am I doing something to the Tyres to cause this or is this a bug?
