Always a contested point- tyre choice. It makes a difference what speed rating as to what tyres are available, and there's always the horses for courses argument.
However, many people often say that the expensive premium brand tyres are not good, and much cheaper ones are often better. I think that often the comparative Michelins/ Goodyears are just about worn out and 3 years old whereas the new budget brand tyres have nice grippy pliable rubber. Obviously a new tyre should vastly outperform an old tyre!
Like for like, I've found quite a strong relationship between price and important factors like grip, handling and life. In order to be accurate, I think peoples observations need to be based on the same car in largely the same conditions, and I wonder how often that happens
Personally, and from fairly recent experience, I like Michelin, Goodyear, Yokohama and Bridgestone.
Cheaper but decent alternatives are Avon, Firestone (not the F690s though), Vredestein and Hankook.
I don't like Nangkang, Fate, Tigar, Pirelli P6000, GT Tyres, Jing Tong or Stunner (made by Marangoni).
It's worth remembering that it's Michelin that's specced for the Carrerra GT and Veyron- not Nangkang or Toyo.
