i did it........ i found tires that fit 3500 dually`s without spacers i have them on my truck right now i will try to get pics soon. it is hard for me cause i do not have a digi camera. the tires are super swamper ssr 35x10.5x16 they are a d rated 8 ply tire but the load # is 3415lb per single.which is more then a 235/85/16 E rated bfg. the max tire pressure is 65 right now i am running 50 and i have about a 1/2 maybe a hair more between the two back tires. i am sure that with 65lb of air in the tires they will not touch with a load. also i have a fiberglass cap on my truck so that is alittle weight most of you do not have....

 

I'm sure they look good. What's the rated load for duals? I bet if if you put 4k lbs. in the bed of the truck they would touch if you only have a 1/2 inch clearance right now......just a thought
Try to get some pics up

 

Yes, pics, pics. The only thing holding me back from lifting is the **** dually rear end. Unfortunately I have the 17" rims, but if you get 35's to not rub, I'll get some hope for a 17" version.

 

don't forget about the 37" buckshot mudders.
