M1028 dually tires

[319cssb]

Has anyone tried to mount hmmwv tires on a dually? Is it possible without doing major changes? Would you need a spacer on the rear tires? I would like to keep it as a dually set up.
How could that work out?

For starters you would need 16.5 diameter dually wheels.... and yes spacers will be needed.

A Toyo MT 255 85 16 should fit with no spacers and they measure every bit of 33.5in tall.

I may not have been clear. I want to use HMMWV tires on 16.5 rims. Has anyone managed to put these on a 1028 dually?
Is there actually a truck that uses 16.5 dually wheels?

I have hmmwv tires on my 1028A3. You need 16.5 dually wheels with a 4.5 inch diameter bore. I made the mistake of getting wheels with a 4.75 inch bore and then had to get hub centric rings made to center the wheels.

You will need 3/4 inch spacers between the brake drum and inner dual on the rear. I have 2 inch spacers between the duals but could have/should have gone with 1.5 inch apacers.

You may need a spacer in front. I have 1/2 inch spacers up front and I still rub the tie rod at full right turn.

16.5 wheels are getting hard to find and dually 16.5s ... I haven't seen any of those in years. A lot of that old stuff has been crushed and melted back when scrap price was so high. Good luck, it does have a nice look.

Where did you find your rims, curtisje? And how much did this swap cost you, overall?

I also had to get longer studs for the front. $200

Hub centric rings. $40

4 inch lift to clear the tires without cutting sheet metal.

Would it have been possible to use the HMMWV wheels on the front or some non-bud wheels (I have some older trailer rims that are 16.5)? Looks good.

 

[Curtisje]

Yes, you could use hmmwv wheels on the front.

Complete set. I bought and used 2 of these on snow plow and salt spreader trucks. I have since retired the trucks and still have the adapters. 16" dually wheels were a popular item they fit utility trailers we had.

 

[Curtisje]

But that set is to convert a SRW to a DRW. He already has a dually (I think) and he wants to mount 16.5 inch hmmwv tires.

Correct, i have duallies on the m1028.
I am not sure if i want to lift the truck though. Have to let that idea marinade a bit.

This is my 1984 M1008 with hmmwv wheels and tires. I used Off Road Design zero rate 1 inch block and did a lot of trimming on the front fenders. I used Arrowcraft front axle dually adapters on both axles to get the wheels out and get the front wheels to clear everything. (The same company cucvrus referred to, great product)

The rear tires cleared with no problems.

You wouldn't need the front adapters but if you want to run 37's your going to have to either trim your fenders considerably or lift the truck, or a less aggressive combination.
