Having twigged (thanks Phil!) that the previous owner had decided to run undersized (225/40 ZR 18) front tyres & oversized rears (265/40 ZR 18) , and as they were fairly worn I’ve decided to try the whizzbang new Pirelli PZero Rosso‘s at the original wheel sizes. These have got a very wierd tread pattern compared with just about everyone else’s tyres at these sizes/profiles, and I found them initially a bit slippy, but after a few hundred miles & a (very brief) breakout in the rain they seem to be sorting themselves out & I feel a bit happier, though I’m still getting used to them. Mind you, there might be something in this undersize/oversize thing after all?!?…
