Only issue I have is the fronts aren't balanced properly (and maybe the rears too) which was a tad annoying on the French ultra smooth motorways! I'm yet to find a decent tyre fitter, used event tyres for both sets of Goodyears who come out in a van and whilst they did a great job of not damaging the rim (something I had major problems with at two places on my old Leon), they don't seem to be able to balance the wheels.
I had mine fitted at F1 autocentres in hemel and they managed to not put any scuffs on the rims (unlike the prior unamed place in St Albans which may as well have used a hammer to fit the tyres), don't have any problems with the balancing that I've noticed. They are the best I've found yet!
