Like the experience HDX has posted, I have found that you almost never save any money buying cheap tires.
Same goes for cars, pickups, semi's, and off road gear. I have been burned every single time I bought less than a top quality tire.
My money is on Michelin being the best tire out there, in almost every application I have come accross. They carry a heavy premium up front, but the savings down the road are huge. Goodyear and Bridgestone are the other tires I will reccomend, at least in certain situations.
I ran a couple of sets of Chinese tires, 26.5 X 25, on my haul trucks. They were cheap, and a "special deal" from the tire man. I have michelins that were 2/3 worn when the Chinese rubber went on that are still running, while sidewall blowouts have ruined over half of the Chinese tires before they made 500 hours. The good ones have made 1,000 to 1,200 hrs, while I usually get 3,000 to 4,000 from Michelins. Granted, I am running in pretty tough conditions, or they would last longer yet, but 1/3 the life at best is just no deal.
I have seen the same thing with backhoe tires. Had some off brand ones on the front, and was getting flats every week or so. Put a set of Michelins on, and they wore like steel. Only 2 flats in 2 years after thyat, doing the same type of work.
The Chinese and Korean tires have come a long ways, but they are still years behind on quality. For me, it is not worth the gamble.

Let us know how the "wind power" tires hold up after a year or 2. I doubt that you will be as happy with the quality then. I hope I am wrong for your sake, but it is a road I have traveled many times.

2200 per tire for Michelin vs 1500 per for no name. I know there are a lot of them, but the cost of downtime plus the risk of an accident with the huge loads you haul, and I know I would want the peace of mind of a good tire.
Sorry for the rant. been stuck too many times by "cheap" tires.
