Pirelli Pzero Asymmetrico's. Period. Been through those on several cars and they are fantastic. If you had an issue with a previous Pirelli you, yourself bought new, it would be rare. If they were used and broke in by someone else, well then......who knows what went on with them. Used, abused, hit, not properly maintained, not rotated, not balanced right.......people are usually the problem, not the product.
