These tires where on my truck for the last 3 1/2 years or so and I've never had a flat or even so much as had to add air to them. The approximate tread remaining is as follows 1 @ 6/32", 1 @ 5/32", 1 @ 4/32", and the last one is 2/32 or less and is pretty shot. These are very similiar in tread design to a lot of the AT tires out there in this size. So if you only really need to replace 2 or 3 of your tires to buy some time before shelling out $1000 or more for new tires, then this is an awesome deal for you. All 4 tires DO hold air, and have NEVER had to be patched, plugged, or repaired in any way. These are very good tires, just worn as described above. First $100 takes all! . 410-322-8333 Location: Forest Hill/Belair 21050 it's NOT ok to contact this poster with services or other commercial interests maryland
