If you were going to remove rear wheels on a dually for winter use and MPG improvements which ones would you remove, the inside tires or the outside tires? Any thing special needed to do this or is it just a straight remove one and bolt the remaining one back into place.

Just a thought for those who like to make other people go how about running the inside on one side and the outside on the other side.

For good looks I would choose the outside ones left on. Would that hurt the axles any? Too much offset causing increased load on bearings?

I don't haul anything in the winter and with fuel prices the way they are anything to save a buck.

 

Well, I haven't heard of this theory before but if it was me doing this, I would just get a set of the SRW rims/315 tires to use for the winter. I know that a dually stinks in the snow and ice and my truck does way better than the dually I had before it.
Actually there's a guy on another board that did this permanently to his truck. I think he runs 315s all around and kept the dually fenders on the truck. He probably got some rims with a lot of offset to the outside....

 

It's not so much the driving in snow as for MPG reasons.

As for putting on different size tires I'am not going there, Too many ad-ons on the last CTD and all it cost me was a bunch of money and headaches. I bought the truck stock and that's the way it's going to stay.

I have heard of other guys removing a rear wheel on there duallies and I don't think it hurt anything, but I was checking just to make sure.

 

TTT. Some one on this forum must have done this or has information.

 

How much mileage to you expect to increase?? I have done this on an old truck I had-no gain.

 

Cant see as youed gain a measurable amount, unless you removed the fenders also for less wind resistance. But then the way the fenders are shaped they slide through the air quit well as is. I doubt you could measure any gain.

 

You'd be losing about 150 pounds of unsprung weight, and reduced rolling resistance as you'd have two less tires on the ground.
Due to the tires being offset, the difference in snow would be negligible.
The front tires just push the snow directly into the path of the dual rears.

o.k. thanks for the information, but which wheel combination would you take off or doesn't it matter in terms of good verses bad for rear axle.

 

I have pondered this same thing for sled pulling if I remove the inners I could make it into the lower weight class. But I would only remove the inners because if you remove the outers you could make the truck unstable! Because you are actually running the inners inside the front wheel track. I could see bad things happening in the snowy winter months that would make running just inners a very scarry thing. So I would have to say if you do go for it Go out
