I have a set of three Dunlop SP Maxx tires 295/35 R21 with 7000 miles on them. We had one of the four go flat and had to replace all four of them. The joy of all wheel drive. Tread depth new is 11/32 and these are 8/32. We kept the three that were still good. These are typically $500 a piece will sell for $250 plus shipping and handling which will be added on your price based on your location. I have photos as well.
