The stock Potenza RE92's have terrible scores. They are rated 21 our of 22 tires tested with a lowest score 2.7 for ice traction.

A good alternative all-season tire, the Yokohama AVID TRZ. It's lowest rating in winter conditions is a 7.1 for deep snow traction and 7.2 for ice. It rates number 1 in it's category out of 29 tires. Price- $56.00 each.

Rated number two is BFGoodrich's Traction T/A. This tire also has good ratings, though not as good as the AVID TRZ, and costs $62.00 each.

Both of these come in the stock 185/60/15 size. The only way to beat these traction scores is to use a winter specific tire which will then suffer in dry traction ratings.
