I have had my GTI Pirelli edition for just over a month now and already three of the wheels are kerbed. Two are tiny little scuffs that aren't so bad but one is TERRIBLE. I am responsible for two but my old man did the third.
With these 18 inchers, p-zero tyres, there is simply no room for error at all - touch the kerb and they're f*cked. I told my dad this and yet he insisted on trying to use the tyre to lightly 'feel' the edge of the kerb and buggered it.
Again, on mine, there is simply no leeway at all for miscalculation and extremely tight, lightly touching the kerb, parking.
I just always make sure I dip the mirror (wish I had lux pack) and leave at least an inch. Sometimes I stick out but I can't take the risk. Gonna get the wheels refurbed as soon as I've learnt how to park without ever touching the kerb (used to have a car that you could squish the tyre right up against it and it still didn't mark the wheel).
