no one favorite brand
I've had very good experiences with Michelin (XGTs) and Yokamma (A008s - semi-slicks)...OK experience with Toyo (M&S Proxis - not their highest performance/summer only)..I found the sidewalls on the Toyos to be unacceptably weak contributing to some wheel damage. My experience with Bridgestone has been OK at best (I still have my Bridgestones that came with my 87 MR2 that I took off after about a month and replaced with Yokos)- though again never tried the Potenzas. No experience with Goodyear, Goodrich, or Pirelli etc. Am (expectantly) awaiting some Falken Avenis 235/35/19s to replace the Toyos for my Audi summer tires. In the winter I use (Z rated) Vredsteins which are outstanding. Incredible grip/traction in snow and wet, and corner quite well in dry and are fairly low noise. I could easily use them year round - and in fact they are still on the car...just concerned about wear...also hoping that Falken performance will be as advertised - grippy, quiet, long life. The Michelen Pilots on the 330 ZHP seem quite nice as well...very. I understand that Michelin has recently updated and improved the pilot (S2?) - wonder what will be on the 330 when July rolls around?
