I am using my 07 dually for mostly commuting, and snow is amost gone. Has anyone tried running only the outer wheels and taken the inners off to increase mpg? Just want to make sure it is safe and if it makes a gain in mpg. Thanks in advance for any advice, Scott

 

I have seen this done on another truck around town.....dont think it was done because mileage. the truck looked stupid IMO and i dont think it is really that safe. I would say if you that worried about mileage then you might as well just get a single wheel instead of a dually. that might gain you a little mileage but probably isnt worth all the hassle

 

you can do it dont believe that the less 200 pounds will matter

 

I've seen people do it to get a bit better traction in the winter. Reminds me somehow of a dog that came back from the vet.

Mileage wise, I doubt it would improve that much. The dually I have now gets about 1.5 or 2 or so less on the freeway than the SRW I had, but I think part of that would be going from the 03 HO to the 600 and from the NV to the G...

Safety wise, as long as the lugs are tightened properly I don't think it would be an issue.

 

The loss of the weight is not the key, it is the loss of the rotational mass that makes the most difference. I haul a 32ft tag trailer 4-5 times a year and appreciate the dually for that. The rest of the time I use it for work and contracting with small trailers and loads. I just want to be sure it is safe first. (I can always slap them back on if there is no mpg gain) Thanks, Scott

 

I'd say, then, break out the floor jack and the torque wrench and try it.

If it handles funny, or doesn't improve MPG, it would only take a few minutes to put it back.

Since my last SRW and this dually weren't identical otherwise, I can't say I've made a direct comparison, but my semi-educated guess is that you might see 1 mpg or a fraction there of...

Let us know how it turns out.

 

Dually's rule

 

why not just go to a super srw?

 

AKA super single

I think Rickson offers something like that.

Any increase in mileage isn't going to make up for how funny it will look.

 

Yes it is safe. Savings? Less wear and tear on $400 plus worth of tires and breaks. As mentioned above less rotating mass to start and stop. All things combined you should see some savings but I don't know if you'll notice it.

You can now have 3 tires and wheels to put into a rotation schedule and extend the time for tire purchase.

 

BINGO.....what does he win?!

 

I used to bolt up a set of SRW type wheels/winter treads on my Ford dually in the winter. It DID look funny but was much better in the snow/staying in the tire ruts, etc.

If you have your dually rims and use the rim pointed out, it should look fine as far as the tire going to the outer edge of the wheel well. Not a safety issue, should tighten up just fine. I know weveral people who only run all their dually tires when hauling/towing heavy. It should decrease resistance.

As for the rest of you fashion model/srw haters!! ;o) I gotta try something to get those mpgs up, S

 

Actually if you have some nice dually mudflaps on your truck most wont even notice.
