Jaguar XF sportbrake, I have just refreshed the oem 'J' rated sport maxx with another pair on the rear at exactly 12000 miles. Sounds low but i would get lower milage than this on my old octavia and mondeo across a variety of brands, so im quite happy
These tyres are on the 'good' side of fine. They have tons of standard driving grip in both the wet and the dry for daily standard driving up and down a mix of A roads, motorway and towns around London.. They've never given me cause for concern, are comfy and quiet for what is a low profile with a huge footprint on 20" rims. I keep saying standard because these feel reall well balanced for a daily drive on a heavy but fast car.
The sportbrake when loaded weighs over two tonnes and has 200ps, but seriously it has never lost grip when I've been sensible. They do allow the back to step out if that's what you want, but as above this is a BIG and heavy vehicle. Stepping the rear out on a public road in this car may not be the most sensible thing to be doing ... I whave also been mightily impressed with the motorway wet grip , in the worst rain conditions i can remember for years, and in the dry they seem to just dig in (most of the time).
I know the jag spec is xl, and comes with a different model number on the dunlop website to the non jag spec (and actually worse noise and wet grip ratings!) but i am really happy , the tyre does feel especially well suited to the car, which after all is a fast family luxury vehicle / battlecruiser when it wants to be. Its not a GTi and isnt designed for racing through town, but comfy cruising at speed.
