Not sure about the A/S but I have the M/S's on my Tahoe and they are the best tire out there in my opinion. Mine have around 65-70,000 miles on them and I'm positive ill get another 10,000 out of them before next winter. Not sure of the exact mileage because they were on it when I bought it 3 years ago and i personally have put 60,000 on them. They ride super smooth and are decent in wet and snow. Just before winter ill be shelling out the big bucks for a new set but worth every dime if i can get wear like that out of them. Prob be the onl and last set ill ever put in it, she will have 225,000 on her before i wear them out.
