Here's the front wheels I used. (Notice the picture they're using! They did ask and I did say they were welcome to use my pics.)

So the front wheels I used are lighter than the stock steel wheels and stronger than both the stock steel wheels and the rear Alcoa wheels that you would normally use for the fronts. The wheels I used for the front obviously are strong enough for single rear wheel use. They're also a little wider, 7" vs. 6" for stock steel and rear Alcoa's.
Yeah, there were a few people that went crazy in my wheel swap thread saying how reckless I was being and that I was going to kill myself and others in the process. Lol. This ain't my first rodeo. Hundreds of thousands of people have put WAY heavier wheels and tires with huge offsets on these front hubs, along with putting wheel spacers on every imaginable vehicle. What I did is basically like putting a wheel spacer on a stock hub, but actually even safer than that because it's a steel spacer made by Ford. The front hubs and bearings on these E450's are extremely strong and I believe they can easily handle what I've done.
Not only that, I went over exactly what I was doing with the big wig Engineer/tech at Buytrucktires.com that has a ton of experience on wheel swaps and he actually said it shouldn't be an issue.
