hi guys, when choosing you tyres and viewing them in 2010 they showed one ring with an amount worn out. what do the new two rings and numbers mean? cheers steve b.t.w. the games great really isn't it? loved racing 50% at india yesterday, starting on primes in my merc and chasing and passing vettel on the last lap as he ws on primes then, only for me to run out of fuel 2 corners from the line!! - loved it.
