Hi John
Thanks very much for this.
It is Dunlops which I have on my XK and I have had good mileage and use out of them. I have just hunted around both locally and on the web for the same tyres and prices are reasonable just now, There is also very little variation in price. No major bargains to be had on the web- unfortunately!!
I did look into using winter tyres as I have tried to use the XK in cold weather and it is a pretty expensive sled!!!!! The cost of the tyres and the storage etc put me off, although I also have a Range Rover Autobiography with the 5.0 litre supercharged engine so do not really need them. I live quite high up so we do get a reasonable amount of snow and ice.
I may look around to see if I can see a reasonably priced set of 19" wheels. If the option of shockers is not on then it is possibly a better way to go to reduce wheel size.
Once again, many thanks for your input
Cheers
