My Michelin LTX M/S have about 10-12K on them and they still look like new, I reckon because they are. They will probably dry rot before I wear them out, my 2000 just turned over 60K, but I did a lot of research before I bought these tires and found them to be the best highway and mild off road tire on the market. No they ain't cheap buy good tires ain't cheap and cheap tires ain't good.
