The winner is: The lowest bidder. Those stinkin' wheels are cheap made, and don't hold up. I've seen several dozen broken. Seems to me it's the vibrations and road stress. The trucks I see from Western Texas all seem to have the chronic problem. The rough roads, dirt roads, and carrying a trailer or just whatever in the back make 'em break like glass. The trucks I see around the DFW area don't have the breaking like the western trucks, unless they're 4x4 and they go off roading. There is a reason why. They are cheap cast aluminum. Low bid. Poor quality. Nothing new for OEM. I've got one set on an '01 gas rig I use to feed and check cattle in, and I have a rear right one that's got a slow leak. I'm sure when I pull it down, it's gonna have a crack somewhere. There's a customer's '01 in my yard that's got a flat, and i know it's cracked, I can see it, and if you pour water over it, it bubbles. There is also a brand new set of Eagle alloys in my shop waiting to go on it when I get the time to fix it. Eagle Alloy wins my vote for quality, as they use an injection mold forging, which basically presses the molten aluminum into the mold, and squeezes the air out of it. Only thing better in aluminum is Alcoa. All others are made out of country. Alcoa forges a solid peice of round rolled aluminum @ 17" in diameter and however long, hammer forges it, heat treats it, and then cuts a wheel out of it. Not the cheap way, but the strongest way. Of course, they cost twice what others do, too. Personally, I go with Eagle's or steel wheels from Rickson or Stockton Wheel.
