I had Avon ZZ3 tyres on my Mk5 (225/40-18), found them to be pretty good. Grip was fine in wet and dry, wear was good, 15k on the front. They also had a decent edge protection lip. I could get the Avons for under £100 and at that price they were excellent value.
I would consider them again when I need to replace my current tyres.
I have Dunlop sport maxx on the Mk6, only done 250 miles to date, but initial impressions are that they are slightly better than the Avons.
