Not really a tyre buff myself so can't comment on the specifics in detail but just felt tyres did not have great grip. I drive a late model Audi A4 2.0T and am based in Brisbane, Australia so weather here is mostly dry and warm 9 months of the year. Summer months are hot and balmy with tropical rain periods. Being a front wheel drive, when accelerating with a bit of keeness, traction control nearly always kicked clearly feeling the tyres could not grip enough for this car (in the dry). In the wet, never felt unsafe but drove more cautiously knowing heavy acceleration would not be pretty from the lights. Maybe this has something to do with being a front wheel drive causing the front to lift slightly, hense loosing traction - I'm not sure but I am putting a full set of Michelin Pilot Sport PS3's on tomorrow so will be sure to give 'em a good test. Being a 1st time reviewer, I'll do my best to come back in a few weeks to provide comparison. Also, I've rated tread wear as average but again, I may be a little harse as it may be the way the tyres are aligned/balanced (I really have no clue) but they are worn heavily on the outside edge - mates say they look almost bald (all tyres - changed front to back 6 months ago) but there seems to be plenty of tread on the inside. Have acheieved 35,000klms (24k miles)which I consider poor to average as I got over 70,0000klms from an earlier car (Subaru Liberty) and my last Audi 1.8T I traded after 3 years, just under 50,000klms (33k miles)with the original tyres (unfortunately can't remember brand). Think I had Michelins of some sort but I know this is bit of a nana car and all wheel drive so clearly going to be less aggresive on tyre wear. What I do find interesting about the Potenza tyre is that even though I know nothing about tyres, I never really liked the feel or how they handled - which seems to be supported by the many reviews on this site, which would include a lot of people who do know something. Heading into Xmas, wishing everyone safe driving.
