Had Fulda radials on my Porsche.
The more expensive Porsches wore Pirelli P7s. I had no real complaint with my Fuldas, however.
The one tire I won't buy is Michelin. Oh, excellent tires, I admit. But the painfully heavy-handed tv commercials they used to run, with the baby sitting in the tire, and the suggestion that if you don't buy Michelin, you're consigning your infant children to a fiery death, just annoyed the hell out of me. (Personally, I like tv commercials featuring silicone-enhanced models in bikinis, possibly cavorting on the beach with beer-drinking dogs.)
