37" tires on a Dodge Dually

[timmcgraw67]

What is necessary to mount 37x12.5x16.5 on Ford 16.5 Duals? Spacers, Lift, anyone done this? I was thinking a 3" lift may do it but need input. I have 315 75 16s on my 98 Dodge Ram 2500 Currently. No lift. So that is where I have an idea that it May??? work on a 3" lift..... Correct me if I am wrong. Thanks

I just put 37x12.50x17s on my 97 with a 2" spacer. The only rub I get is on the back of the inner fender where it sticks out toward the front.

I used to daily drive 37x12.5x16s and it took a 2" rear wheel spacer to run the tires with factory wheels as well as a 7" lift but I could have run them with only 3-4" of lift.

So you ran a 2" Spacer on the front, 2 between hub and inner dual, 2" between dual? No lift? or was it 2" Coil Spacer, if so what did you have for your rim spacers?
