Changing Tires
I know the rule is to change tires between 5 & 7 year of age no matter the miles...but just how many of y'all do this?

So here's the science behind the tire aging limit:
Rubber compounds age according to temperature. It's called the Arrhenius equation. A quick and dirty version is: Chemical reactions double with every 10°C.
What that means is that tires in - say - Phoenix age much more rapidly than tires in - say - Minneapolis. That's one of the reasons why there is disagreement between users.
Then we have the issue of trailer tires. Many of these weren't designed well and failed early. This had little to do with aging and a lot to do with material fatigue. This is also influencing how people perceive tire life.
