Tire mystery solved

So we got some good and bad news about the truck. There isn't anything wrong with it, I think that's good news. The bad news is that this is just what this truck does to tires. It seems we noticed it sooner than most others because Paul drives so much for work. We got the truck in May '06 and we have 63,000 miles on it. The front end mechanic at the dealer we took it to has the same type of truck, although a few years older, and he is on his third set of tires in about 60,000 miles. His wear pattern is the same as ours and he said this is normal. This puts us in a bad position since it means we would need to replace the tires about twice a year. The only suggestion is that we try going down to 17 inch wheels and tires. We may try it next time we need tires but the idea of buying new wheels AND tires doesn't make me very happy. If we do decide to try it there is no guarantee it's going to make any difference. I wish an older used car was an option but I don't think anything in our price range can handle the amount of driving Paul does.
