Can't speak to the brand, but:
Assuming they're both on the same side, I'm impressed that the tire place put TWO new tires on. It sounds like they know what they're doing... so often shops/owners overlook the probability that the adjacent tire was damaged in the blowout, too. Too many same-side tires that "look fine" are damaged internally, and ten miles down the road they give up the ghost, too. The cascade-of-flats effect!
This is why we carry two spares on our tandem axle trailers. Protocol is, if one blows, its neighbor comes off, too, until it can be inspected on the inside.
