I have these on my Jaguar XF and despite my fears of these being ditch finders I have been pleasantly surprised, an excellent all round tyre that is available for next to nothing because of brand snobbery.
I drive my car pretty hard and have 255 bhp and a shed load of torque going through the rear wheels and they have proven to be perfectly acceptable in all conditions, yes I can make the rear end step out in the wet, but I could also do that with the previous Dunlops which were 5 times more expensive.
Give these a go, you will be surprised, I was. Unbelievable value for money.
