I rode my mudzilla's in the snow yesterday on my Prairie 650. They were great. I saw all the other quads spinning more than me, and a lot of them getting hung up. I had so much traction I was almost bored.

However, one of the trucks slid off the road, not bad, but we got the quads of the trailer and a Rubicon pulled it back on the road.

The mudzillas do not grip on ice. They slipped more on ice than the stock tires on the Rubicons and Pairies. But when it came to deep snow, packed snow, or a muddy crossing, the mudzillas were awesome.
