lol , after this thread I had to go check my fronts and got a fright!.....
Michelin Pilot Sport PS2 7.5mm from new (9/32") according to the website, now WELL past 1/2 worn on 7k miles (all on APR stg1 ED30)
mmm better start budgeting for tyres soon
and just to show the differences my rear Mich Pilot Exaltos have done 19k miles and look like new
