Rosco - with no track days just general driving I'm up 13,500 miles on the Bridgestones... Reckon I've got a couple of mm on the rears with about 3.5mm on the fronts...
Kwick-fit quoted £470, thats with 25% off for 4 new Perilli Pzero's!!!!
Oh and a puncture cost £17.5
If you do have a flat like I did, it's also difficult 2 spot!!! 70mph with 10psi in the tyre car was still rock solid
