I keep track of tire age on my vehicles and trailers.  I tend to err on the side of caution.  If it were my truck, it would get new tires.  Here is the Discount Tires position, which I where I get my tires.  They would not service them.  And yes, I have replaced tires based on age that looked brand new, such as spares which never hit the ground.
