Eh Toyos Proxes 4 slightly better than the 912s but not by much. If you live anywhere where you get snow just get some dedicated wheels with snow tires. You will not regret it. I put them on in November and take them off around late March.

I had Nokian Hakkapelitta 2s 2 years ago and I was unstoppable in the snow with my 00 Civic Si. They were amazing. I actually just purchased a set of Hankook WinterBears that went on sale at Discount Tire Direct for 4 tires for $100 with free shipping. They are still sitting in my garage. I think my next set will have some Ecostuds too for those icy days.
