Those are on 6" wide wheels as well...It looks like his is only on 2" wide spacers due to the width between the rear tires. His setup looks very similar to mine with 35x12.50s.

Within reason, there is nothing wrong with mounting wide tires on narrow wheels. The taller the tire is, the less noticeable it would be..i.e. 35x12.5 will be better than 33x12.5, but 33x11.5 will give about the same effect as the 35x12.5. The only concern with the wider tires on narrow wheels is the crowning of the tread, but by keeping the air pressure a little lower you can limit that, only air them up when you know you will be hauling something heavy.

My tires are rated at 3860lbs at 65psi. If I had them aired up that high the tread would be crowned significantly causing the middle of the tire to wear faster than the outer lugs and the ride would be terrible. I run mine at 35psi in the rear and 40psi up front. This keeps my tread nice and flat and a much nicer ride. At that pressure my tires are still rated to hold roughly 12,000lbs, much more than the truck, and even with a 7,000lbs trailer behind it and pretty heavy tongue weight the tires did not appear to sag or heat up at all so I didn't even air them up for that load.

Here you can see that the tread is still nice and flat, with no sidewall sagging or irregular wear, and they still have nice tight handling (as tight as you can expect with a 35 year old 1 ton truck )


And here it is on my old tires, 285/75R16 which works out to about 33"x11.2"
