Being old enough to look primarily for safe returns home, I think I'll get new tyres for the next track day and keep the existing ones for the road.

Honestly I am unable to judge how much life there's left on them. They may seem to be usable but rear one has two track days on them. Motorland Aragon is a fast track and the front one may die during the day. And that's something I would hate.

I will keep on taking pictures of used tyres. Maybe in the future we can make a map of tyre status in a way similar to what people do with spark plugs...
