Just a couple suggestions (from someone who actually has installed countless sets of tires over the years and sees first hand how they do on all kinds of cars):
Stick with the OEM size/load/speed. This information will be on the tire placard on the car, either in the door jamb or on the inside of the fuel filler door.
Stay away from anything directional. They'll turn square, and you cannot cross rotate them to keep this from happening.
No one tire is going to provide everything to everyone. High treadwear numbers mean long lasting, but also mean a harder compound, which means less traction, especially when wet. Tires rated for "all seasons" will be mediocre in all seasons, because the tread pattern is a compromise. They won't be as good on dry, hot, summer roads as a "warm weather" tire, and won't be NEARLY as good in snow and ice and bitter cold as a "winter" tire. If you actually have a sizeable winter weather potential where you live, you may be better served with an extra set of wheels shod with winter tires.
Price is: you get what you pay for. Most of the el-cheapo no-name tires that are made in places like Taiwan, Indonesia, China (especially China), Philipines, Thailand, etc. are going to be garbage. The Korean brands are marginally better, but still vary from not good to worse.
These cars bend wheels easily. No idea how (mine don't), but I see Volkswagens with bent wheels in here every week. Don't assume the person installing your tires will know to look for this, let alone tell you. You can balance a new tire on a bent wheel, and it will balance out to zero... but it still is not round, and it'll still shake. And in many cases, a NEW tire may shake WORSE than the old tire, because the old tire may have worn itself uneven due to the bent wheel. This happens a LOT. I see people on this very site constantly describe this exact same thing. All it takes is someone to LOOK at the tire/wheel combo spinning on the balancer to see an 'out-of-round' situation. Most places, even "real" shops like ours, employ low level "tire buster" guys to do this work, and they often butcher this seemingly simple job up. I do not allow our guy to touch any Volkswagen wheels/tires if I can help it, I do them all personally. No mangled wheel bolts for me.
And above all else, keep the tires aired up and rotated properly.
