@Limited22 this is the best solution I've found so far, is to run the Ford 6.5" steel inners plus aftermarket 6.5" aluminum outers. Should help minimize the amount of spacer needed, if one is needed at all. Will also allow you to keep the tire warranty since the OEM 6" wheels are 0.5" too narrow if they want to get technical about their warranty (Minimum rim width is 6.5" for the 255/85R17).No spacers, but running 2020 ford inners (17x6.5") which have a slightly higher offset. +6mm additional offset (IIRC). Same bolt pattern/hub bore. Going to replace the night edition rims with some aftermarket 6.5" wide rims eventually.
It's apples and oranges with aftermarket wheels vs OEM. The aftermarket have conical lug nuts that gain more thread engagement than the factory 2pc flat faced lug nuts since they thread down past the face of the wheel. For OEM wheels, it appears the longer studs 6509420aa are needed to be able to run a 1/2" spacer and maintain the 21mm of thread engagement. You want "1.5 x thread diameter" thread engagement. 14x1.5=21 which is exactly how long the threads are on the OEM nuts.


The answers are literally in this thread already. Tons of examples.Hey guys, could I get some input here?
2018 Ram 3500drw. Stock steel 17’s. Looking to do a 2in lift, front and back.
Can I go 255/85r17 without spacers on the rear? Any pics on here of this size tire with or without spacers on factory Ram wheels?
Difference in stickout with 255/85R17 on an American Racing 204 6.5" wheel vs a Ford OEM 6.5" steelie. It's roughly 13/16" more stickout.
Comparing the Dodge vs Ford steelies, the Ford moves the rear inner ~5/16" closer to the leaf springs, reducing the amount of wheel spacer needed to be able to run a 255.

Summit or Duallywheels dot com. I'd discourage doing business with Duallywheels after the experience I had though. They fed me all sorts of incorrect info and I ended up buying front wheels twice.where are you getting the Ford inners from?
You need a minimum of 1" between the closest points of your tread (at the bottom). 1/2" spacer is barely good enough for 255's. You'll need 2" wheel adapters for 285's.Hey fellas, so i have a 2024 limited dually for my welding rig, and need to replace these garbage nexens before our cdn winter hits. Thinking about going with the toyo AT3, a friend of mine is running 285/70R17s on his identical truck, so it really has me thinking about going with a 285/75r17 on mine they look awesome, he has a 1/2" spacer and longer studs ordered for his truck. I know there not technically supposed to go on the 6" rim but it also seems like many are running this size tire with success. I was just curious for those of you running this size are you seeing even wear on the tire? The fella with the black ram and at3's with 285s truck is almost exactly what i am going for. I forget what size spacer he was running but we calculated there should be about 1/2-5/8" between the tires with a 1/2" spacer. I think the less agressive side wall on the AT3 would help in that area as well.
That looks scary AF.I run a 1/4" spacer with 35x10.50r 17's.
Ive had 14k lbs hooked to her more times than I can count and never had an issue.

Nice! What are you running for a tire? I have a 1/2” spacer and longer studs. Iam just torn what route to go 255-80-17 or somthing similar to yours. A 10.5 wide 34 or 35 would be awesome. Id really like to go with the 285-75-17, math says there should be pleanty of gap. Although tough to tell… with the welding bed fully rigged out iam about 3500 lbs all the time on the truckI run a 1/4" spacer with 35x10.50r 17's.
