I have purchased tires for years from Dunn Tire though I will never buy here again. I always got their service guarentee in the past, knowing that if anything happenned I had the piece of mind that my tires had a warranty. I come to realize their warranty isnt worth the paper its printed on. When my tire blew out recently they "prorated" my tire and I got a 6 dollar credit towards a new tire. Not quite worth the $30 warranty per tire eh? I will never do business with them again, and I would discourage my friends from doing business with them as well.
