single tires to duals

[DEUCE1209]

I have a deuce that came with singled out 11 x 20's from GL ( <--- my avatar). The tires are getting to the point where they need to be replaced so I've been thinking of changing it to dual 11 x 20 tires in the rear. I've searched but cant really find what i'm looking for going from single to dual tires. it's mostly the other way around in the posts. I've also looked through the TMs and still don't have a clear picture. Because the trucks i do have all came singled out, I'm having trouble trying to figure out what I'll need to get this done. I know the obvious things are 4 more tires & rims and flip the hubs back to accept dual tires. will I need a spacer between the tires or do i bolt the rims together? thanks for any help or advise.

You do not bolt the rims together. After the hub flip, you will need Budd caps to hold the inner wheel and Budd nuts to hold the outer.

II've been thinking of changing it to dual 11 x 20 tires in the rear.

I have driven my Deuce in both single (current) and dual configuration (before) and can honestly say that I would not go back.

You are not giving up load carrying capacity with singles and on-road and off-road manners are better when singled out. I especially disliked the axle binding and how the rears pushed the front wheels in tighter turns.

The only thing duals have going for them, in my opinion, is the looks.

I agree with the Cattleman, only I think you would gain a little horizontal stability on duals. I would not trade the driving ease for the added stability unless I really planned to do some serious sidehills. Glen

I'm on the other side of the fence. I like the fact that I have additionl spares onboards at all times.

Ditto-and I know this is a minority opinion but clintogf and I have had DOZENS of deuces in all configurations (dual, single, radial, ND, winch, non winch, etc.) and I just can't feel any difference in the "ease of driving" that everyone talks about.

They all feel the same to me.

My reasoning for liking duals is that I think the singles that Deuce1209 has on his truck look odd to me. I do like the look of the Super Singles or HEMMT tires, but stock singles just look anemic to me. And the fact that if you do get a flat with duals, you can drive further to a good spot to change.

I am switching my Deuce from 11.00-20 singles over to duals, mainly because I like the look more. I carry two extra spare tires now just in case. I don't think one way or the other is better, I just like the looks of it dualed.

Take the two rears from one side and bolt them on to the other. See what you think. It will tell you %100 if they will clear.

Has anybody ever put Dually wheels on the front?

Here is an Old, Old, Old Trick that we used for some serious off road slush.

We change our front end gear ratio to one revolution less than our rear.

Example:
If we had 4:11s in the rear, we put 3:08s in the front.
It enabled a truck to pull itself out of deep ruts with ease.
Hill climbing is made so much easier.

This is not a change over made for on road travel, it is only for those who are extremist.


I have always wanted to setup a set of dually wheels where the outside tire is much smaller than the inside. This way the the smaller tire can have a much more aggressive tread, and it only comes into contact with the ground once the larger tire has sunk up to its rim.

 

[toddm]

I am not looking forward to flipping the hubs back, but you gotta do what you gotta do.

My M342 came with 11.00x20 duals on the rear. That being said, I found that due to the fact that the rear boggie has a tendancy to move sideways to some degree that the inner tire was rubbing on the spring pack hold down bolt wearing out the side wall of the tire. In fact I changed back to the 9.00x20 tires because the 11's are too heavy for me to manhandle. Also all my other trucks have 9.00x20's. Fewer parts and spares in the motorpool.

Oh My God we think the same way!

Bet that is rough on bearings and U-joints. That is an enormous jump in gear ratio. I know they used to run 4.10 front and 4.11 rear, but to go to a 4.11 to a 3.08 is huge! I can hear the transfer case crying from here. Bet it was next to impossible to get out of four wheel drive.

 

[buzzinhalfdozzen]

I liked my singles. Truck sank like a rock in deep mud, but I don't think the duals would have helped much more

 

[91W350]

On the flat tire issue, I would much rather run one flat and destroy the tire than take a chance in traffic changing one. Along the same lines, I would rather recognize right away that it is flat and look for a solution, than catch one on fire not realizing it was flat. Once you get a tire and undercoating on fire, it is next to impossible to put out. Besides, it must be just my luck, but front tire flats are much more prevalent than rear tire flats for me. Everybody has their own idea of what works good for them, it would not be much fun if we were all the same in preferences and tastes. Glen

Think: snow, mud, dry sand, silt, loose gravel, and then think competition.

Like I said: It's not for everyone.

I prefer duals for the reasons already mentioned...Added stability and built-in spare tires.

My Deuce also came with 11 by 20 singles. I like the looks of duals better, but I plan to stick with the singles. The 11 by 20 singles do not look that bad and I should pick up some mpg and also less inertia to get rolling or for the brakes to stop.

BTW I am running my Deuce up to VT this week, heading up 91, sounds like your neck of the woods.
