I am on my 2.125nd set of Michelins (had to buy just one recently). The first set still looked brand new when they came off despite their age, and I am 18 months into a set of Energy Z Coach tires (315 / 335s on 22.5s) . They are absolutely fantastic in terms of road holding, ride quality, and emit almost no road noise at any posted speed. Better than the already great set I had before. I have heard Toyos are a fine tire too, but when you're talking many thousands of dollars either way, I went with what I thought was a safer bet based on prior experience.
