two rims on back of a dually instead of 4 ?

[hrose]

Hey guys

During the winter, my f350 drw is not hauling or towing anything heavy,
The heavier ill be hauling is my snowmobile.

Where i live, we must use winter tires (snowflakes) from december to march, its the law.

Since my trucks gonna ride without lot of weight on it during these 3 months, can i only use two rims instead of 4 on the back ?
(Wheels exterior side)

It would spare me to spend a couple hundred bucks for 2 additionals
Tires that i kinda dont "need". Its also gonna give me a better traction i guess.

Im planning to buy rims and tires soon an id like to know if someone already did it or if you think its a bad idea for some reason, let me know please.


Thx guys

If you do this I would say pick up a set of steel rims to install on the inside. This will protect the brakes and then you would have the correct spacing. I would not install your old tires on the inside as you could never match the same height of the tires. I do not think any reputable tire store would install mismatched tires anyway.

The cost of the supper singles and wheels would be awful high and you would be better off just buying six snow tires that match at that point.

During a heavy snow in Illinois I appreciate having extra weight and more tread on the road. They both equate to a better "bite" in most types of snow, which is what you are trying to achieve aside from the legal requirement here. And if you aren't carrying much payload then you might not have as much wear and the tires might last longer, making the additional cost difference less of a concern.

You drinking and posting again? The only reason I understood your post was because it didn't have to travel too far...

hmmmmmm, drinking.....Dr P or iced tea.....no alcohol in either....

No, called droid auto correct.

Those michiblows were "XDS M+S" traction, had a Bridgestone all position up front, now have double coin ribs.

The GM dually had Toyo AT's up front, and M55 tractions in the rear. Used that one to go up Snoqualmie with chains required in RWD only! screw the 4wd part of the equation. Traction tires and the Eaton locker did well. Did the same with the 96 GM I had, with an aggressive Cooper hwy tire going up Stevens! Did not go into 4wd until I got into the parking lot.

Time for bed........

I can type a bit better on a laptop too!LOL!

Since it sounds like you need to buy wheels for the second set of tires. What about using wheels designed for a single rear wheel truck. It will look goofy with the tire being deeper in the wheel opening but would not cause bearing problems.

I ran four M55 Toyota on rear of 4ad dually, hwy up front. No issues in WET me us snow. Have michiblow ads attractions on dumbstruck rear, hwy rib up front. Again, no issues in snow
Super singles imho would be a better option, if I could get a traction style.

Thx for the answers, my biggest concern is about that my brakes are very exposed to get hit by something when the inner tires arent there

It doesn't work worth a damz in certain types of mud. BTDT years ago.
The drivers were always trying to climb the sides of the ruts left by the front tires.

that makes sense to me but ask the provincial govt. a dually with snow tires on only the outside certainly would have better traction than a non-dually or dually with singles on the rear.
do 4 WD or 6 WD require snow tires on the front?

Yes, 4WD (2 axles) or 6WD (3 axles) requires that all tires be the same size and same tread pattern.
Since I run M&S rated traction tires year 'round, I don't have any problem.
I'm not going to attempt to explain the leverage problems with the bearings when running a single tire where duals should be, but, yes, it CAN cause bearing failure! NOTE: That is not "WILL", that is "CAN". There IS a difference. You might get away with it with no problems. Just be aware that there could be a problem in the future.

Did it for years with my seni's when I had a flat on the road. Always singled to the outer and the lug nuts should not be an issue unless the wheels are pilot mount, then you'll need an inner rim (with no tire on it) to index the hub.

[All_I_could_aff]

As for the stud thread, Nuts will only have to travel in an additional quarter inch or so with one rim. Remember it's just perfect mess of the mounting flange of the second rim that would be different, not a whole rim width

Not good for the wheel bearings unless you run super singles!

Wont do a thing to the bearings running around empty. Agree if he was talking loaded down.

I am curious about this also. Would you use the inner wheels so that they track the front tires or the outer wheels so they make their own track? Which would give better traction in the snow?

Depends what type of conditions whether you want to track the same or advantage for the rears taking a new bite of snow. Realistically it will make pretty much zero difference in any day to day conditions.
I couldn't handle driving around like a BNSF hi rail truck, on the inner duals. Just too gooofy looking for me. I'd run singles on the outside if I had to choose.

Honestly what I'd do if I was bent on only buying 4 tires for a 6 tire truck is use some old wore out tires on the inside duals and keep the air low in them so they don't interfere and put the good tires on the outside. Mainly so I didn't look like a dufus.
