I deliberated for ages on these tires but in the end i went for 640DX ×4 ON 235,55,18.
Instantly noticed they were whisperingly quiet,
They are very responsive and feel well planted,
Pretty much straight away i noticed they feel a little twitchy at 3 figure speeds and want to completly let go in the wet at these figures(scary).
Driven on normally they are great but dont like being pushed in the wet i find.
I am on 10000 miles now and i reckon about 3.5 mm left on the fronts and rears look new still.

Would i recommend them?
Yes if you take it steady in the wet and want a quiet ride.

Early doors with these but I am really impressed with the wet grip. These tires are the best tires I have ever used in the wet.
Very low road noise, bags of grip and a nice steering feel.
I normally go for the big names brands but these tires should be making the big boys worry both with their low cost and exceptional handling.
Wear is yet to be determined but I place safety above all else and these tires certainly feel very safe. I have had bad tires in my time for the same cost of these and these are as good if not better than some of the very well known premium brands. I won't hesitate to get another set and in fact I am looking at getting these for my wife's car soon.
