These are OEM tires on my 2009 Infiniti G37x. They are driven in spring/summer/fall and never in the snow. I put 37,000 miles on them.
The Dunlop is an average tire with good road holding (dry/wet)on the highways. However it creates fairly loud noise on road joints. During the last year the car jarred on ruts and became very sensitive on the steering (pulling to the sides especially on braking). The wear on these tires is quite acceptable. I replaced them because of the handling issues and age (5 years).
The Dunlop is more expensive and not cost effective. I put on a set of Michelin Pilot Sport A/S3 which I have yet to test.
