I agree on the interco for DD'ers. Alot of people have told me that their tires have worn one heck of alot quicker than expected. We have alot of commuters here that commute to NJ and NYC, about 100mi one way or 200mi a day.
I bought BFG AT KO's and have been keeping an eye on them, wear at 10K was not measureable, they work fine for me off road, the only grumble I have about them is that they are not as good on wet roads as my pirelli scorpion AT's were. I did have to get a new one, picked up a nail in the sidewall so the tire was totaled but I bought them at BJ's Wholesale and they came with roadhazard.
So far I am pleased with them even though I swore I would never buy aother BFG product again. Next time though I want to get a set of GY MT's but they will be mounted on spare wheels for weekends.
One comment on milage, I feel that if a tire does not last AT LEAST 50,000mi it is a waste of money unless for special application, but for daily driving 50K is my minimum.
