I guess it must be the hot summers here in the Ariz desert because I only have 15 K miles on these 5 year old BFG TAs and they are spent . I don't know what other drivers are doing to get the kind of high mileage I read about in the reviews but it hasn't my experience . Nice quiet tire, very comfortable and they wore evenly after two rotations . I guess I was mislead by the Commercial designation when I ordered them because I didn't think 25 K miles was too much to expect . We are retired and not hot rods with this Tahoe LT SUV with 143 K miles ( just broke in ) : - ). I expected more than 15 K miles .
