245/45R20 - Great tire for winter weather, which we have had a boatload of this year. The tire takes the worry right out of bad weather commuting. It cuts right through the snow and slush and seems to offer a decent grip on glare ice. Coupled with the car's AWD, it's like I'm driving a rally car/tank when other cars around me struggle to move. I probably drive with too much confidence, to be honest. The dry performance sees a reduction in steering precision and ultimate dry traction, which is standard for a winter tire. The noise is also somewhat elevated due to the open block design and high sipe density. I purchased a second set of these for my wife's SUV, which now enjoys the same benefits.
