Few questions about tyre wear and track grip.

Hello guys.

Was wondering if theres difference between tyre wear when you drive out from pit and when you do flying lap. Do you suffer more wear from flying lap than driving out yourself and warming first lap? Also should you drive pack to pit or just return to carage and skip.

2nd question goes for tracks. When you finish p1. Do the track stay warm for next sessions trough all practices and qualifys to race? Or does it always reset between sessions.  


Thanks.
