Right just spoke to Mr Tyre who know there stuff & supply lots of the Teams etc .
After Nov 2014 any tyre made not just Track tyres have to conform to lots of testing ..wet grip ..dry grip ...noise ...etc !
Where all the track tyres are coming undone is Noise ...
All the top end tyres are only meeting F grade & they need to be G to pass .!
Everybody has stocked up on old tyres made before 2014 as that's ok ...
But the EU has given Track tyres until end of 2016 to get rid of old stock ..
Now here's some info ..
No tyre including new Toyo R888R that's the first top end tyre to meet the Regs are anywhere near as good as the old tyres YET ????
Dunlop & others are working on tyres & trying to give DZ03g quality but because of Noise it's going to be difficult so say ?
They are basically lined slicks ...
Hopefully this info is of use ...
It's what I've been told from Motorsport Division & it's not My Knowledge ....
I'm sure at some stage they will stop you using even old tyres for road ?
