8 years old is 2 times too long for a tire.

I've been wondering about this. There is a lot of information on the Internet that says 3 to 5 years is the lifespan of a tire. However, it all comes from people who sell tires. Goodyear does not give a specific lifespan but says storage and operating conditions matter. TireRack.com says life span can be 6 to 10 years. My experience on low mileage cars is that after 6 or 7 years the tread starts to harden, hurting performance, but I've never had a structural problem.
This all interests me because I probably use my trailer only a few hundred miles a year. I store it inside and move it often enough to rotate the tires, so I'm inclined to push the envelop a bit on tire life.
