New squarer tyres for 2012 by Pirelli

He would probably be able to reveal what measurements are taken though, surely?

Don't take everything you read / hear at face value, folks.

I would have thought square tyres would have very large oscillations in the contact patch vertical force

Yeah that's what I thought too. Surely if you wanted to measure wear you'd have to measure how much tread you have left? I can sort of believe monitoring degradation; if Pirelli constantly monitor the tyre temperatures and sort of run their own live simulation; from which they work out deg; but wear? How?

Only thing I could say is very, very accurate slip and speed/rpm sensors, you'd be able to work out both the change in acceleration as the tyre loses rubber and correlate that against speed/wheel slip/engine rpms on the straights for the tyre diameter.

Hell of a set of sensors on board the chassis these days if they can do it that way though!

I don't think you'll even need that - Paul Hembery is very sociable and answers any questions you tweet him.

I've asked but he didn't answered. Maybe I was right.

Pirelli could have also figured out how to write their logo circularly, like it was ever since I've heard of the brand. It sucked last season too. In 2012 it is changed but still looks amateurish and unsophisticated. Like someone was bothered to bend the text and stamped default logo. Pathetic.

BTW, this was the way to color sidewalls:

Should have gone with these sidewalls-
