I think I will get double life out of the tires by running two sets
M/T = summer tire
A/T = winter tire
The M/T has not been too bad in the rian, but I have been careful NOT to over drive it
I do not want to find the limit in the rain on a highway off ramp
leave the black striping of guard rails to soccer moms in Expeditions or Escalades

PS - I do like the hum of the mudders on the street, more descernible then the A/T but not annoying
And at very low speeds you can actually feel the bump, bump, bump as LIL BLUE rolls from tread block to tread block - NICE!!!
Come November 15th or so the A/T tires will go back on
I view them as a much better all weather performing tire and those nice blocks on the M/T might chunk or gouge when hardened by cold

M/T's really dont chunk in the winter. atleast my coopers never did. but I will tell you what they just down right suck if there isnt over 5" of snow if there is ALOT there great if its just a little they suck.
