Hey,
for the first 6 laps in the last super series race I was on push hard using hard tyres. As they got warmer I switched to hold position. Before I did this my tyre wear was at 5 % average. But then it suddenly increased to 8% percent even though it should decrease as I switched to hold postion. I then switched to back off but it would not decrease tyre wear at all. It decreased it like 0.3 % in maybe 5 or 6 laps.
