I'll see what the MPG hit is. I'm not a hypermiler, my main concern is wear on the suspension. I'll try these out for a while then in the next year or two spring for lighter snow tires.
They are perfectly balanced and give a secure planted ride. Definitely makes the car feel bigger.
Last year driving through snow drifts on country roads, I thought I was headed for the ditch. I'm confident these will do the trick.
