average miles
My car came fitted with these (Jaguar rated) tires when I bought it. The rears were new and fronts I imagine quite recent. The XF-S is a 1.8 tonne 275bhp/600Nm car so with a lead foot driver, the tires take a hammering. That said, even on full throttle out of a junction I've rarely seen much wheel spin, in the wet the tire is confidence inspiring and on the dry they grip well, making the car very chuckable.
After 18,000 miles in 16 months rears are 2mm in the middle but still 4mm on the edges and the fronts are badly tracked but still have over 3mm elsewhere. so If I'd rotated them and dropped the rear pressures a bit I suspect they'd easily have done another 3-4,000 which would have been pretty good imho. Usage has been mainly 6 mile commute with a number of 200 mile runs.
Recently I've noticed some tram lining and a bit of vibration and of course the ride isn't as good as it once was but as the tracking is clearly out, that may explain some of it and grip has remained excellent throughout, even in the wet.
Considered Avons and Khumos as replacements (used to use them on my Merc) but whilst they are probably as good grip wise and probably comparable on wear, I had to frequently rebalance them, which I haven't on the Dunlops. I guess thats where the extra quality shows. Just ordered 4 more.
