My opinion is the mt's were great at first because they have a big area to displace the water. Now with about an 1/8" of tread left I already did a 360 down the road in the rain and always spin. They are as good as slicks with the big tread blocks when they wear down. I say get rid of them at about 1/2 tread or get something with better siping.
