Rusty, the Hankooks are 2 steel + 2 polyester + 2 nylon, so yeah, they are different in construction from the Michelin XPS Rib. That said, functionally they're pretty identical... both are ribbed highway tires not intended for snow, with better-than-average rolling resistance.
I just got home from a 20 mile drive to get the Hankooks. First impressions:
1. I LIKE the handling and the ride and the quietness... but then, I'm coming fresh off of big ole lugged snow tires, so almost anything else would be smoother and quieter.
2. Don't know about wet traction yet; the roads are bone-dry. Stay tuned.
3. They ran just a touch warm on the way home, but its my understanding that's expected for brand-new tires, until the plies all get to know each other and settle in. Again, stay tuned... .
4. Thank goodness the sidewall lettering is black. I just HATE the name "Hankook". Just screams "oriental import... another job shipped overseas". And, somehow, I find the word "kook" on my tires to be a little disturbing
The guy at the tire store says he sells tons of 'em to ambulance and paramedic fleets. I consider this a good recommendation, since I used to drive an ambulance many, many years ago and know that when you're doing 70 down the wrong side of the road in the rain you live or die by your tires, and ambos are even heavier than our trucks.
