want to convert my srw to a dually and run 37" hummer take offs

[TFaucette]

when i wear my current tires out i wold like to find some 16. 5" wheels so i canstart running 37" hummer take offs and would like to make it a dually, i have swaped in a dana 80 from a srw second gen which is about 5 inches wider than the stock axle and i also have a full set of 2" wheel spacers which i am currently only using 2 for the front. so i am wondering if the srw dana 80 thats 5" wider than stock is enough to make it a dually and use the 2" spacers between the duals to allow for the wide military tires to be used as duals.

 

[DVolk]

the trick will be the wheels finding ones to fit the 37s the rear end will work just have to get a spacer is all

 

[Simplysmn]

The srw dana 80 will not work with dual's you will have to change the rearend to a drw Dana 80 or better yet just run Singles your wasteing your time trying to run dual 37's there too wide to run that way

If you get Hummer take-offs make sure that they are radial, not bias. We have the Limestone Military Refurbishment Center up here (Many Hummers are sent there) and the take off bias ply tires wind up on Craigslist and such.

Anyone I know that has tried them say that they will pound you to death. All have flat spots where the Hummers sit so much plus tires are quite old when they are removed for replacement.

will the duals clear the drum? or will a 2" spacer let it clear the drum? i was thinkking that if it would clear thn a spacer could be used inbetween the two wheels to spread them enough for the 37s

 

[Simplysmn]

Waste of Time n Money plus it would look Stupid with tires sticking out that far and I bet you would get questioned buy the cops also

DUDE! Seriously? It's his truck, not yours. Why you hatin'? That's no way to treat your fellow TDR members. Many are hear to learn, not to be chastized. They paid their membership dues, too. Chiding remarks don't help anyone, including the reputation of TDR.



Personally, I think it'd look good, but... ... With the Goodyear Military, I don't think 2" spacers will make it work. It will take at least 3" to clear the drums, maybe 3. 5, but the 16. 5s may have a little more room... ... Then you'll have too much weight on the spacers and lugs, unless you get someone to machine you a center pilot spacer, then you're going to have to have ANOTHER 3. 5" spacer, mayber larger, between the duals. You can get some custom wheels made, but they will have to be designated inside and out, as the inside can only go back so far due to clearance against the springs, so most your backspacing will have to go outward. Those tires take a lot of room to clear, and the sidewalls will rub severly without the correct spacing, not to mention, a 6. 5" wide dually wheel is too narrow for the tire cross section, and really shouldn't be mounted on a wheel that narrow... ... A dual rear axle will make it a little more feasible, where the inside wheel will center pilot, then you can use a spacer on the outside wheel to get the clearance you need. Now, there is the concern about overwidth. Some will care, some won't. If it's over 102", it's not legal, and on a regular dually rearend, it will be overwidth. Where I live, no one would care, but some places... ... ... . While I actually think it would look good, done right, I'm not sure it's really feasible. I run 35s on my '03, and it runs 100" wide. Those Military tires are wider..... It's pretty easy to go with the 35s, though. Wheels are pretty easy to find, simple spacer, and then you're ready to run.



If you're dead set on a 37" tire, try Interco Tire Co... ... They make several sizes that can accomodate what you're trying to do. Their 38. 5x11. 00x16rim in the Bogger tread will work, it's an awesome offroad tread, and they'll work with a 3-3. 5" spacer depending on your wheels... . http://www.intercotire.com/tires.php?id=13&g=1



A dually axle would make it a lot easier, and probably safer.

 

[Simplysmn]

Well what he is tring to do is put dual 12. 50 in wide tires on the back of his truck it's going to stick way out and cause alot of problem's if we can show him it's not worth it Why not talk to him . IMO he sound's like a Kid that is tring to make a drw from a srw on a budget all I'm trying to do is show him it's a Waste of Money and won't work with the rearend he has

 

[HHhuntitall]

Yeah, but that was just awful harsh. You want them to hang out and learn, not run off with their tail between thier legs. How can you expect the younger generation to learn from the older? Most already don't want to listen and think they know better. If they're dead set on doing it, it's their time and money. For the general safety of them and more importantly, the public, why not try to educate them on the subject? While I think it would look good, I'm not sure how to safely do it with his current setup, and be both safe and legal.

 

[Simplysmn]

HH your right and I'm sorry for comming off so harsh I guess I should of said please explain why you want to run dual's and on top of that dual 37's they wern't nmeant to be run as dual's Yes there a Cool tire but They won't work as dual's . Also he posted this same thing on another site asking the same thing

 

[cerberusiam]

Yeah, thats why I kept quiet. Don't like to dissuade creativity but somneone has to point out the cost and asethics may not be compatible.

With an axle already wider than normal it would probably take custom wheel to backset the inside dual enough to keep close to legal, then, too much backset and its dangerous. Same with the spacers. Even driving around empty I would be concerned about spacing that far to get enough room to run duals. Definitely would not hook anything but a small lawn mower trailer to it.

I would be concerned if something broke. Currently, there is going to much legal maneuvering around a delivery truck that blew its transmission out on the interstate. A large piece of the case went over the center divider, hit a vehicle and killed a child in the ensuing melee. The company thta owns the truck says they contract maintenance and thats the issue, the maintenance company says not our problem the operators are responsible.

Either way if you build something like this and it breaks and somebody gets hurt, well, I would have to err on the side of saying its not worth the cost and liability.

 

[HHhuntitall]

I have a bad day sometimes, too.....

Well, I'm sorry to sound like I'm busting your radial reproduction devices, but it sounded like you didn't want the guy here, and he was buggin' you..... I'm sure you have your reasons, but I didn't mind him asking the question. I think the idea has merit, and he's not the first to think of it... ...



As a tire, they function in a specific way, radial or bias-ply. In that respect, and not to be deliberately argumentative, but I believe it can be done, but the best route, IMO, would be with a Cab and Chassis axle, with custom made dually wheels. That's a lot of weight to be thrown around with road force. Now, if we don't give him some reasons, based on logic and experience, and his curiosity isn't satisfied, and if he just goes out and bolts some on, using some flunky, poor designed spacer, it could come off and hurt himself, or worse, someone else. I DO agree with you in that they shouldn't be mounted in a conventional manner. BUT, if we advise him in a good direction, he both learns something, or is at least is given the opportunity to, and potentially prevents a dangerous situation. He may never have thought about them being over-width, and spent a great deal of time and money to discover he can't legally run them that way. He may also have a private stockpile of the tires he has free access to... ... that might justify the setup costs.....



IMO, it's little to ask of ourselves to be helpful for our time here. I enjoy helping people, and when a project turns out good, it makes me feel good knowing I actual contributed to something worthwhile, even if it's only words. That's one of the things I enjoy about the TDR. Another thing is how I'm normally treated when I ask questions.



As a following thought about their functionality, and giving the merit I referenced to above, the surface area and agressive tread of those tires dualled might make for a respectable sled puller addition... ... ... Oo.

 

[TFaucette]

well, i am 25. and i personally think it would look good (saw a 2nd gen dually w/ 37 militartys all the way around that looked awesome) and just seeing if any one has any experience with it to see if i can easily do it. i want to run the 37's just because they are cheap and abundant and thought that if i have to find 16. 5 rims anyways just see if i can easily make it a dually and run 6 37's around the truck. thanks for your thoughts whether positive or negative, i find TDR to be one of the most knowlegable and helpful forums around especially compared to tdiclub.com (wife has a common-rail tdi) they can be really hard to deal with and want you to search the entire forum before asking any questions. i've also been told "this forum is for competition only!" on compdiesel before.

yeah, i was also thinking that. want to start pulling work stock if i can get the he351 off of my third gen (have a garrett gt3788r to eventually go on it)

Funny you mention TDIClub.com, I have been studying their site thoroughly the last few days (being a VW TDI newbie) and I thank Robert Patton silently at least once a day for not using the same search software as TDIClub.com (reCaptcha) that requires you to fill in the two words in the box before the site allows you to search.



What a P. I. T. A... ... ... ... sometimes it takes several attempts to get a search underway.

Have you had trouble with it as well???

And that's what I'm thinking with the single wheel axle... ... . Just a lot to mod to get it to work right. It'd be easier to do it with a CC axle... . Overwidth and if you hit anything, it's your Obummer... . I can tell you a lot of those exploding parts stories!!!



I saw a 19. 5 that came off a service truck (I guess) in the South bound lane on Loop 12 in Irving. A small car hit it and it went up and out of sight!! It dented the hood, crushed the windshield about half way up, and then rolled the roof down a little before launching up and South..... I was in a friend's '94 Western Star, headed North, looking out and up from under the Sunvisor when I saw it about a 1/4 mile ahead of us, hit the pavment and go up again. I lifted off the throttle ..... I got on the brake pedal just in time to lock the brakes down!! I barely slowed in time to keep it from hitting the truck!! One problem, though. I'm still sliding. 22 tires white-smoking(80 ton lowboy, triple axle). The tire hit right in front of my truck, but I'm still sliding around 60mph... . As it bounces, it's around 6' off the ground when it catches the top foot or so of my grill and pushes it, the radiator, and hood back on top of the motor, and then dissapears at WARP 2 speed to the Northwest, into a neighborhood. I couldn't see where it landed, but it went a LOOOOOOOOONG ways before it fell in behind the tree line... ... That image is burned into my mind... . That was around 14:00hrs, and it was close to 21:00 before we FINALLY got towed out of there..... the tire was never found, AFAIK. The old hood is behind the shop at Robert's, and you can still see half the bolt pattern beat into the grill. No one ever reported a lost tire, either... ... I still remember Robert saying in the most calm voice you can imagine,"Ohhhh, this is gonna hurt. " He wasn't upset at all..... what a guy.

It'd be easy in my opinion, but I've got most of the crap laying around to do it..... The adapter is my biggest concern. It needs to be a center pilot, and good quality steel. And those tires are really to wide to mount on a 6. 5" wide wheel... . It can be done, but I'd not recommend. ANd the tread is going to wear in the center faster than the outside unless you keep it loaded all the time. Lots of issues, there. A regular dually axle is going to make you too wide to be legal for street use. That one you saw may not have been legal... . just sayin'. I'd want to get Stockton wheel to make me something wider and stout, that I'd not have to use an adapter on. It'd be heavy, but that's not your primary concern obviously, if your installing 37's!!!! :-laf

 

[DVolk]

Id like to use a set of 35" BFGs on my dually crew cab the tires are 16. 5s

Ive thought just finding a set of single dual wheels to run them out as theyed only be winter time tires only since i have 5 of them not that a 6th tire would be a big deal the wheels are the issue if there avalible

 

[TFaucette]

sorry, but i can't help myself. i think this is just sexy.

 

[roachcoach]

You posted this on CF and I told you that you could not do it with a SRW rear end. I had 35 12. 50's on my first gen without a spacer between the wheel and drum, I am running a C&C dana 80. It is just wide enough to allow the tires not to hit the leafs. It was super close though. You would have to run a ridiculous spacer on yours to make it work. If you want to deal with the hassle of making the spacer(or buying one) go ahead but you should just find a C&C rear end. You'd probably have the same amount of money in one of those that you would in buying the crap to get your 37's to fit your SRW 80.

35 12. 50's

I'm not posting this thing up to show it off, I want to give you an idea of how far your tires are going to stick out and what it may look like. I am running a 2. 5in. spacer between the tires, I probably could have went with a 2 or maybe even 1. 5in. and made it work but I had a 2. 5 at the shop at the time.
