dually wheel question

[rs74]

Who owns the brown and the black dually in the photos above. I like the black one and are those wheels chrome plated. I am sure it cost a bit to have them resized and then chrome plated but I am sure it would be worth it.

Anything that increases track width will cause more wear on the wheel bearings, but look at it this way, it is no more leverage on the bearings than if you bought wider wheels with less backspacing. If you are afraid of wheel spacers creating more leverage, then forget buying wide offroad wheels because it will have the same exact result. I have ran 1.5", 2", and 2.5" spacers on 3 different trucks now and have had no issues with any of them. One of them being a 01 2500HD with 135k mi on original bearings in the rear axle, and the front hubs were replaced at 80k mi when the lift went on. For the last 55k mi the truck was on 38x15.50 tires with 2" spacers in the rear to match the front track width and regularly towed 10k lbs or more with no issues.

I couldn't find the owners name. He is a member here, that is where I found the trucks months ago when I was looking around, but I actually had the pictures saved.

I think around here widening a wheel runs $50 or so for just widening/narrowing, or around $75 if the center needs to be moved as well.

You can buy just the outer hoop from MRT racing wheels for around $75 in any width you need and just put your center in it, or they also sell centers, but I am not sure if they sell one concave enough to work for dually applications. Stazworks can build you a complete wheel in any width you need with many different center options for around $300. Of course you are getting to the price of or beyond aftermarket wheels now but keep in mind you are getting something one off, no one makes 16" dually wheels any wider than 6.5" in the aftermarket, although I think there are some 7" wide 17" dually wheels out there.

I was thinking maybe some 35's, so I didn't know if they would fit on a factory rim or not. I also had the thought that maybe having a set widened would be about as much as an aftermarket set but wasn't sure. I was kind of going for this look.

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"
