My 02 now has Toyo Proxes 4, very happy.
Kumho ASX was a bad weather upgrade over oem Dunlop, and much cheaper.
Toyos are 10% more than Kumho from my local shop, worth it for a bit quieter, smoother, grippier on pavement, same on snow.
x2 on the Toyo Proxes 4s. They've surprised me in the dry and wet, however I'm not sure how they'll do in the snow.
I have Nitto NT450s on my 90 Jetta and they also do pretty well, however they weren't that great in the snow.
The tire reviews on tirerack.com seem to be accurate, check those out. (wrc)
