I've got no complaints with the supplied Goodyear Eagle F1 AS3. In the dry they have a lot more performance than I am normally willing to use, and in the wet they feel as confident as my wife's car does in the dry. For day to day use, they are more than up to the job. I deflated the tyres to the recommended performance pressure (35 front, 32 rear) rather than the eco pressure (42 front, 39 rear). After nearly 8000km, they still (visually) have most of their tread left - I should really measure them. There is a little evidence of hard cornering, but I would be disappointed if there wasn't
