My HiHy and I...funny, it rhymes. Just celebrated our 30,000 anniversary. And I am religious about keeping on track with everything in my car. I have been noticing that my tire wear has been increasing and rather than going to rotate my tires, I bought new Goodyear Fortera's as I live in Minnesota. At 30,000 miles, my treadwear was at 3/12, and that was with the stock Integrity's at 5,000/rotation intervals. I purchased my tires at Sam's club, as it's 6 months no interest on the sam's club credit, $40 Goodyear rebate, and unlimited road hazard, rotation and balancing included. Best of luck.
