If you drive it in the snow, then I would suggest that you dont fit Dunlops, as I has these on my LS430 last year and can honestly say that it was the only time I have ever been terrified to drive a car.
On a journey, for no reason at all the rear would just break away, and I would find myself pointing at traffic coming the other way. There was next to no grip on the front end, reversing into my driveway was a wind the steering over and see which way it goes affair.
To say that they are dangerous is an undertatement, and there are many taxi owners and tyre fitters around here that agree with me.
I had a set of Michelins fitted this year, and although they are summer tyres, they have transformed the car in the snow.
It still breaks away, but only if you want it to. The steering is fine and it goes where yo point it.
It could still be lairy, but only if you drive it that way, it is now predictable, which is more relaxing, and more fun!
