Had the wheels off today, I couldn't find a date on them.
So took them to my tyre place and he say he's seeing it more and more these days, suspects its to do with the chemistry of tyres these days and partially down to the way I park.
Swinging into my drive is always hard lock and would load that area of the tyre considerably and it might go some way to explain the tearing.
I splashed the cash for a full set of of F1's and dropped the bare rims off at the powder-coating place, changed the rear brake pads, cleared all four sunroof drains and retested the car so fairly productive if somewhat expensive day.
