I have been building my 8x8 for almost a year now. It's going to be the best truck on the streets, period. It sounds like the OP has a good idea of what needs to be done and is heading in the right direction.

Yes sir. I went with the skinny ones. I think the skinnier ones will work better as this truck will be used mostly for highway commuting. I also plan on putting 3 stacks coming out of the bed. I like to be different.

Didn't work for me either.

You need a Rebel flag with those stacks and weren't you getting Thornbirds?

Yup MonkeyDog, that's the one.

I've never driven one, but my brother tells me the duece and a half's all drove like shit, front duals or not. He says the only way they ride better is in the back of a cargo plane!

So you're building one curbdog?
I checked your profile but didn't see anything about it. Do you have a thread up somewhere or can I pick your brain here in this thread?

Grassman has been over helping too. He has a sweet camera phone. I will ask him to get some pics next time he is over.

Hmm. I have thought now about the comments on the extra loads and the alignment settings.
Both have merit. The front duals will add extra loads, and the alignment will have to be played with.

The business end of any truck is the bed, and nothing there is changing significantly besides a worker style bed and a sleeper cab. All told, it would ad about 1000 lbs.

The front will get extra weight in the form of a bumper, winch, and the modified fenders. Less than 500lbs up front.

Considering how overbuilt these trucks are, I "think" the extra loads won't matter enough to care about.

The alignment might be a real problem. Tell me if I'm thinking thru this reasonably.
The tires I'm going With are speed rated at 100mph. I gotta tell you, if I'm gonna do 100 in this rig, it's because Satan and all his demons are chasing me, and if that's ever the case, speed won't matter! I'll be happy to govern the speed as 75. That's plenty for me in this type of vehicle. If I want speed I'll build a Jeep Wrangler or a hotrod car.
So the speed limits will affect the alignment needs.
The caster setting won't be too big of a deal with wider tires, or in this case, duals.
Camber will have to be triged out to find the max angles that can be used and not wear out the tires faster than I can replace them.
Eyeballing the triangles, I'm guessing the camber will have to be reduced by about 30%, which would make for more wandering while driving in a straight line.

Hmm. Maybe, instead of running the same size tires on both rims, I can run a slightly smaller diameter tire on the inside. It would prevent me from rotating the tires without breaking them down and moving them to other rims in other locations, but it would allow me to run a reasonable camber angle and not wear the inside tire more than the outer.
I think I like the 2 size tires in front, but it isn't a perfect solution either. I can still carry only one size spare, but if the inner fronts need to be replaced, I probably will have to order it, since I don't think I'll carry a spare for it.

Part of my reasoning for these thoughts is because the front rim is the same as the rear inner rim, so adding the second wheel is just a matter of adding the outer rim, and clearance for the outer tire. And then tweaking. Maybe lots of it.

As for things getting caught in between the tires, there is a higher risk in the front, but I don't think it's as severe as it sounds.

Any thoughts?

You sound like you got it all figured out. The 2 tires sizes up front should make a world of difference. Time to start spending some cash and start building. It will look badass as hell!

You start putting extra weight on a steering axle and you will quickly find just how "overbuilt" it really is.

To give you some idea I plan on running 54" tires offroad which will be less weight as your tire wheel combination will weigh. I am placing these on a 5 ton axle and still I expect to have some breakage due to the tire size with my driving style.


Sounds like your dead set on doing this. The only real world benefit will be the very slight amount of a larger footprint that your going to get offroad.

Why not just use the second "outer" wheels for off road use only?

How are you even going to mount these? Maybe, some kind of hub spacer ring thingy like the cheap import wheels use? You going to run the inner wheels hub centric with the outers lug centric and constantly tighten them to avoid the tire heading off into a playground?



A better option is just to buy some wide off road only tires designed for the terrain you plan on running and run normal street tires on the street.





I am cheap, and think outside the box, but there is no real world benefit in doing this. Now if this is some kind of thing where someone says you can't do it then I get it. Go ahead and do it to prove them you can down a road where if something happens no one will end up dead. Then remove and go back to normal reducing the damage you have caused. I would rebuild the hubs after running a few miles knowing just how much strain your putting on them.


The trucks that you see doing it are show trucks, trucks running at slow speeds over short periods, or someone not willing to spend the extra to get the proper tires.

There are very few axles that will support the weight, strain, and fit under your truck. Your talking like a 106 or 5 ton outer's and 14 bolt inner hybrid to even get close to have the bearing support needed. That's just to avoid the constant bearing wear. There is nothing to fix the fact that at highway speeds your going to chew up the tires due to alignment.

I am not trying to wreck your idea. But, this should really be a off road slow speed thing to get across a field or something if done. It simply is not going to happen at highway speeds with any sort of reliability.

Yeah, I know. No matter how I figure it, there doesn't seem to be a way to do this and still have a highway speed capable and reliable rig.

What a bummer.

Thanks for the feedback. Now on to the next brainstorm!
