My tire life was just fine, but I put new front and back on just because. In back went an Avon AV72 (200-55/r18 as I recall). Monday (while it was 93 out), I picked up a nail and found myself baking by the side of the interstate. Long story short, I call Avon sales and they tell me every tire they sell has a one year limited mileage road hazard warranty on it! I told my dealer (who had been happy to take another $300), and off we went. We'll see how I all rolls out in the coming days, but that's a pretty strong customer commitment. They'll get more of my money for sure! Now the speedo is at least closer, and I seem to be up to 27MPG too.
