I purchased these tires when upgrading my 2003 Chevrolet Trailblazer to the 20 rims. I have used Yokohama in the past and am consistently happy with the price/performance factor.
These tires are wearing wonderfully, I do rotate them every 10,000 though. They are quiet, and not harsh riding, the sidewall has some give.
It's an SUV- so as you could expect, I don't corner like a corvette. But on more than one occasion, the grip has surprised me, and the tires don't protest- no squealing through corners.
I rated these low on Hydroplaning and Deep Snow. I believe the cross section has more to do with that than the tire, but on a 5000# truck, I shouldn't have hydroplaning problems, at reasonable speeds. Also I HAVE to use 4WD now in any snow over 3- once again, I'll attribute this to the width of the tire (mostly).
Overall I'm happy, but when the snow flies, I find myself wishing for some snow tires.....
