Your experience sure doesn't mimic what I have seen. I didn't like the snow performance once they were worn to 60% or so....but damn near couldn't wear it out to make the company buy new ones.The chipping makes them unreliable, I get about 10,000 miles out of M55's on logging roads. They do great on pavement but the chipping makes them flat prone around 50% tread life.
This tire probably only has 5,000 miles on it
