This is an update to my previous review from April 2012. So far so good. Tires seem to have little if any tread wear. Have had one patched already, good luck on finding a true authorized retailer to utilize the mfg road hazard. I think my only complaint so far would be that the tire picks up and holds onto a lot of small sized gravel. Think it's because of the number and width of the ribs. This doesn't seem to be much of an issue unless it's a nail or screw... Anyway, I really have no other complaints. These are much better then the worn out Conti's I replaced, which only lasted 27K miles and drove like a tank in the end! Yes, ive driven a tank! So far they are quiet and handle well in dry and wet. I do a lot of high speed driving for work and these seem to handle quite well on my heavy SUV. Time will tell.
