I've noticed shorter expiration dates on just about everything

Yup. I just heard a mattress ad on the radio, in which they were trying to say a mattress has an expiration of 7 years. Whatever!

When my wife and I went out to Idaho to pick up our truck, the tires had great tread and no visible sign of dry rot. Because the owner told us they were "very old", we toyed with the idea of replacing them before we set out to drive it back home to NY, but decided they looked good enough. On the 2nd day of our trip, we regretted the decision when the front right blew out and almost threw us off the road at 55 MPH. After a quick change of shorts, we decided to buy 4 new ones on the spot. Here's how it looked:

Looks like you got lucky and did not damage you sheet metal.

This is interesting- a lot of good info. I read an article on how rubber hardens with age. When tires are new they're much softer than aged tires. The article mentioned a farmer who bought a new combine and used it to shell a field of corn. Corn stalks can be pretty tough and by the time he was done with his first field- the front tires (think monster truck tires) had stalks stalks sticking out them and they were going flat. Firestone replaced them but told him to install stalk skidplates in front of the tires to smash the stalks down. They also said that if these tires were a year old they would have hardened enough that the stalks wouldn't have punctured them. Maybe some tires come apart because they're getting too hard??

Looks like you can see contrast between aged grey outside vs nice black inside. Did you notice born on date?

Didn't know about that back then. Actually, my spare is one of the old ones. Next time I'm under there, I'll check it out.
