I just replaced all 6 tires and decided NOT to go with Michelins. I researched for a couple months and ended up going with Toyo OPEN COUNTRY H/Ts from Les Schwab Tire Center (all over the northwest).
Here's why: The specs were very similar to the Michelin Ribs I was going to get (steel sidewall, etc). The price was about $100 less per tire. They are in stock at every Les Schwab around the west (very important). Finally, they installed all 6 in less than an hour.
It's already payed off: While heading into Reno last month I got a puncture from a large bolt. I found a Les Schwab only a mile away and they replaced the tire for free in less than an hour. Crisis averted. I made a video about it:

My lesson learned: Go with quality tires you can easily find replacements and service for.
