Trailer Tires...trusting the Goodyear Endurance?

I had ordered the Carlisle Radial Trail HD in a D range. There was a shipping problem. Discount Tire is stepping up to the plate offering the (in stock) GY Endurance tires at no additional price (from $57 to $108 / tire).

Doesn't seem many miles have been put on these? Surely Goodyear did all they could to eliminate another mess of a trailer tire.

It seems like an obvious decision price wise, but what say you?
