The reason I ask is that 3 of the 4 original OEM 20" Ford wheels on my '06 F-350 have cracked. 2 fronts and 1 rear. First one was a few years ago before I towed the trailer. I've found ALOT of these 20" wheels have cracked like in the picture below and should have never been put on the truck IMHO. These wheels came as part of the "chrome" package on some Lariets in 2006. These wheels are a safety issue and just looking to END the problem.
