some people theorize that the curing process makes the wheels brittle. I have seen no empirical proof of that, only stories of friends of friends whose friend had a powdercoated wheel break. One member on here did have wheels fail after coating, but I believe by what he posted it was because the coater put them through a much higher temperature burn cycle to burn off the original paint. I know that Forgestar and other wheel manufacturers powdercoat their wheels.
The downside to painted is that they are much easier to mess up during the mounting and dismounting process. Once the tires are installed, they hold up fine though.
