H1 wheels on dually CTD fit's 35" x 12.5"
Every since I inherited my 93 from my dads estate I have hated the narrow front of the dually. I also needed new wheels as the Michigan winters had taken their toll on the orginal rims. I also think duallys suffer from too much weight and two little/much ground contact, this makes the front wheels sink in the mud and the rear wheels get little traction in winter.
I went searching for dually rims with custom offsets so I could run bigger tires at high loads. The max off the shelf offset dually rim I found was 5.350", since custom made rims were not in my budget I considered 19.5' but they were more expensive.
This lead me to get a complete set of 16" hayes-lemmerez coined replacement rims and a set of firestone destination M/T 235-85-16 tires for the dually and live with the narrow front. These rims give you an extra .700" between the dual tires. I still didn'te care for the look of the truck, the wheels were still small at 32" diameter. The ride was also very stiff.
Where I work we build assembly machines, well we were building a machine pressing the studs in 2 peice H1 hummer rims. I noticed that these rims have an extreme offset, 7.25", I checked a few offroad sites and they had used them with dually axles. Dually spacers are 4" so this makes the net backspacing 3.5 inches.
I then when looking for H1 rims, not much selection but there are a few. I ended up with a set of 16.5" x 8.5" one peice H1 steel wheels for 150$ these wheels have a 3800 lbs load rating @ 50 psi and are DOT approved. After some minor modifocations, clearancing the center hole to 5" and adding 60 degree lug seats they were sand blasted and painted. For tires a got a closeout deal on some Wild Country TXR tires, model GR-80 35X12.50R16.5LT 3380@50 psi load. After balancing total cost $850, plus a fith of Gin for our painter to spray them.
The next issue was lugs, 1 ton duallys got 5/8-18 lugs so I needed som 60 degree seat lugs in that thread, gorillia had some. We next mounted and instaled the tires, and removed the dually fender flares.
This makes the wheels and tires rated for 13,000 GVW, which is more then the dually rims were rated for.
My plan is to run these through the winter and then try to get a set of Cepek / Hummer products 17" aluminum wheels.

We plan on cutting the fronts to match, this will give the pre-runner long travel suspension look. We are going to bolt in some heavy rubber sheet to close the gap between the inner and outer fender. We also might look into a fender flares but I don't want to change the truck, I may want to put it back to a dually some day.

After this winter I am going to look into getting the ONLY 17" aluminum H1 aftermarket wheels so I can have many more tire choices. They are load rated to 4500 lbs!

The front is lifted with 2" lift springs from skyjacker and a 2" (ramcharger central style lift) for a total of 4"
The rear is lifted .5" with skyjacker springs that allows the removal of the rear blocks.
I now have bilstein shocks on all four corners.
The RCC lifts consists of a 2"x6" peice of 1/4" wall rectangle tubing with 1" round tubing (1/4" wall, or 1/2" hole) spacers that are on the hole locations welded in. This spacer sits between the front frame and the spring mounts and is bolted in with Grade 8 bolts. I also installed two inch longer rear shackles in the front springs to match the lift. I will get some pictures.
One note, I think the front springs rear shackle on stock trucks are all to short my springs were hitting the frame. After installing these wheels and tires and the two inches of addtional lift I have noticed that the truck rides better than ever.
Finally my only caution which these rims is that there is a very limited supply of tires these days in 16.5" There are BFG all terrians, some interco trxus M/T & STS, military 36" C rated and 37" D rated and a few other off brands in 33" & 35". Also these rims don't have a normal safety bead, its slightly less then a normal so they would be great in the rocks or in heavy duty stump jumping.

Asking myself this question, how is the load applied any different then a dually wheel? The tires is mounted on the same mounting face as a dually, no addtional spacer was installed. Yes, the tire envelope is slightly larger on the outbound side, but after over laying the rim and tires in cad the centerline of them is actually farther inbound on the H1 wheel. This is an experiment so that is why I went on the cheap with the steel wheels and the off brand tires. The aluminum wheels will take about 25 LBS of weight off each wheel which sould also help bearing life.

Can you report anymore progress on this? I think I would like to go this route, but wanted to know if you have anymore information on how it's working out.

Well my budget hasn't allowed new rims as of yet. Been watching ebay for some. I have noticed that the inside edge of the front tires seems to be wearing a bit more then the out sides, so the alignment (knuckle angle) may be off, also could be 120,000 mile king pin bushings. Nothing else to report. Wheels bearings seem to be fine. Tires are good, I want to go 37" next time. These solid H1 rims are rated to 3800 lbs each which puts GVW at 15K I have loaded this rig with 4000 lbs of cement bags and it was fine.

I realize this thread is old but....are you still driving on those wheels or did you upgrade to 17's,..also is it basically the same to do to a 2nd gen truck...I have a 96 2500 SRW and a set of civilian h1 wheels and want to do the same thing so I can run 16.5 military tires.
