And it's good to know you buy new tires prematurely - it keeps the stock piles of cheap used rubber stacked up waiting for me to buy.
Blow outs don't just "happen." The factors involved don't even necessarily come from defects let alone age, they come from under-inflation. When you run a tire under-inflated at highway speeds, they generate enormous amounts of heat. Coupled with, say, a 40ton load, now the heat is too much for the glue holding the tire together. (yes, ALL tires are just glued together by the way, not just retreads). Once that happens, the tread rips off. Since the radial-belts are contained in the tread, all that's left are the bias belts so the tire balloons way out of proportion and explodes.
This is exactly what happened with the whole Firestone saga a few years back as well. Under-inflation.
If you refuse to use a tire that's a few years old, by all means go right ahead and replace them, but don't talk to me like I don't have any idea what I'm talking about.
