I have always tried to pick the optimum setup for our cars, and for a while ran Yok S Drives on the MkIV wagon, the V70 and the B6 Passat. Where that got to be a pain was their dangerous cold weather performance if we didn't get the Bilzzaks (WS80 now) installed on time. Since we seem to just put miles on those cars now, instead of beating the crap out of them playing boy (and girl) racer, I have switched them to Advan Sport A/S. Yes, lose a little bit in stick, but as I said, these are actually touring cars so I figure the extra tread life (even S Drives didn't wear badly) and mostly lack of seasonal criticality makes them worthwhile. I have no idea what I will do for XLs on Q7 when need to replace.
Not a blanket condemnation: but the only tire I ever had on the Jetta that was a bunch of trouble were some sticky Michelins (a model they only sold for a short time....gee, wonder why?) that were a PITA in the warranty side. Since then all Yok and happy camper.
I run LT Bridgestones on all of my light trucks, Michelin on class 4 and 5, and Kumho on class 8. On medium duty trailers, have tried several 14 and 16 ply tires, and of all, by far the best have been Sailun (Chinese) - easily outshining Goodyear 614s in every way. On 12k axles where I am responsible for warranty, I have gone to a Yok RY-023 and love them.
I guess what I am trying to express is that you can't simply say all 'XX" tires good and all "YY" tires bad. Each company has a mix of great, good, fair, bad and frigging awful tires for each specific application. You need to do a lot of looking around to collect the information of what really IS good/better/best (tire rack and other owner surveys one good source). Even premium $$ brand name is not always best (as I have found with 235-85 16G).
