Do hummer wheels really work as beadlocks when you use the inserts? I dont want my tires slipping off the rim when I am wheeling. Also will hummer wheels clear Dana 60 GM brakes if they have 3.5 inches of backspacing?

I think hummer wheels are 7 1/2 or 8" backspacing :p

obviously the military isn't going to put up with blowing beads all the time. I don't have the Hummer rims, but I am pretty confident they work.

I have never lost a bead or air yet with the magnesium runflats I have. Did have a leak in one seal, but the guy I bought them from replaced the wheel (it was slighlty bent) and no other problems.

Ed

what about the 8 bolt beadlock itself. Does it do a good job of holding it's bead without the runflat? As you know, Daniel, I'm thinking of welding rockstomper beadlocks to the other side of a hummer wheel, but I need to know if the 8 bolt beadlock is worth a shit to hold on what would become the inside bead.

Hummer rims are engineered to clamp the bead of the tire to the rim on each side. However, if your serious about rock crawling, you can't use the Magnesium style run flat/ beadlocks due to the possability of tire damage at very low psi. I happen to be working on a new improved design in which eliminates the runflat portion.
I will be testing a prodotype at easter Jeeep Safari in Moab this year. I can't say how I'm doing this however I will tell you they will be avalable from Jeepnakid.com & Twistedaxle.com.

The beadlock holds both sides of the tire at the same time, from inside the tire. If you don't use it and put a conventional beadlock on the outer bead, the inner will likely debead at some point. Not a great answer.

I run 16" wide 38.5" tall swampers on my hummer rims and don't have to air down as low as I used to to get the sidewall and tread flex I need. It seems the width of the tire on the "narrow" rim, combined with what I perceive as my TSL's having "broken in" (is that really possible or is it just me?) makes the tires flex quite well at 8psi. Any lower and it seems the tire just kind of folds up on the rocks instead of grabbing better. As a result, I run slightly higher tire pressure than I used to, and have very rarely hit the runflat on the tire. It has happened, but there is no damage to the tire that I can find.

When I move on up to 42's, I expect to have no hitting on the runflat at all. All that said, a beadlock that is easy to install that has no runflat built into it and will fit the military 8 bolt beadlock rim would be nice......

Ed

good answer, thanks. what kind of terrain do you run? Have you ever run anything similar to the Rubicon or the Hammers? I'm wondering how they would hang onto the 42's at around 4-5psi on ugly rocks.

hey can you go by napa and tell Derrick there to check em out??

OR do you have a 3rd (oops 5th) ring with you that I could get together and look at??

are you planing on selling them when you get it right??

Eric check that out you do not need the regular bead lock then... Lets just go with that...

Yeah, that's what I'm thinking. I'll go ahead and be the one who finds out how far you can push a hummer wheel. :D I'm thinking I'll get four of the hummer wheels w/ runflats, special alterations by you, of course. ;)

Remember, you will have to address the steering arms too. Modified high clearance arms inset to clear the rims are the easiest solution.

Ed

This sort off shows what Rock Taxi is saying, This is at 5lbs with the opposite front up on a tree. At 8 to 10 lbs the tires work much better and don't roll on the rim.

here's a shoot of the mag beadlock/runflats

And here are the arms "Ant " made me.

way to come up with the pics! you guys are on it tonight! what's the diff between mag and rubber runflats?

could a guy run those hummer wheels on dualie axles and not have the steering clearance issues? or would the rears still stick out farther than the front?

I asked that same question a month or so ago and I was told that it would work. In fact, there were several responses that said they were doing just that.

I have heard of a couple people having problems with the rubber runflats at low, low air. With the mag. runflat you need to trim it down or it will cut the tire at low air pressure. I have seen that happen twice.

would be a good show though :evil:

If you do not trim the runflat it will cut the inside of the tire. I have seen it happen twice. Don Robbins , Richard Ward, John Lockhart all have trim downed their MAG run flats. Jason Paule doesn't but he tears up tires. When you get tires given to you just to practice then it doesn't matter I guess.

Ever have any problems hitting your lockouts/flanges(lloks like you are runnign slugs) off rocks?

Pat Gremillion has been running Hummer beadlocks on his EB on the ARCA circuit for years!!!!

Just trim them down on a big metal bandsaw. Rather narrow blade, with the guide set. Bolt the tire together and then rotate it around using the guide. Clean up the edges and your done.

I also heard that there might be an aluminum 'hummer' style rim with a rubber beadlock ring, 16.5x8, regular 3.5" backspacing, 8 and 5 lug patterns.....shhhhhhhhhhhh........

later :jeep:

ok smart guys let's put our heads together and figure out how to get good solid cheap beadlocks
here is the plan:

we need someone who has access to plumbing supplies
they should go to Harvel plastics and get a good deal on 18" schedule 40 or 80 pvc pipe. This has an inner diameter of 16" to 16 3/4 ". If these were cut into 7" lengthes and drilled to allow the air in you should have an inner beadlock rim.

The problem is the price. :eek: :eek: $660 for a 20ft stick of the schedule 80 and $535 for the scedule 40:eek: :eek:

this would come out to about $25 per ring give or take a bit when you consider cutting, drilling, and shipping.
now if anyone out there has discounts on plumbing supplies I would like to talk to them.

Would the PVC be storng enough or would aluminumwork better(but would probably add to the price)

On Gohumvee they picture a thick rubber insert that is about 1" thick, is this the civilian insert? It looks like it would work best!

Wouldn't you need to slice down one side of the pvc pipe to be able to collapse it a little to insert it into the tire, then over the wheel. You got a Good idea.

I like the PVC idea. How thick is 40 and 80? 1/8" and 1/4"? I think you would need something thicker than that maybe?

What about cutting apart some low rider tires?

Or having sheet plastic rolled and welded/glued

Or wood...that would be redneck

Or having a mold made for a poly ring....mmmm....expensive

later :jeep:

the schedule 40 is 1/2 "
the 80 is almost 1" thick

you would need to squeeze it a bit but I figure it should go in the tire first. then mount the wheel
aluminum would be great, but also not cheap to roll and weld

the rubber is the civilian insert.
but you could use the tread only from a lawn garden tire

here's you assignment
pick one of these and make one and come back with a report

so the WMS to WMS is the same front and rear on dualie axles?

Well, I thought someone else might answer. Unfortunately, I don't know the exact measurements. I remember seeing them posted somewhere but can't find it now. My question (that I was referring to) was specifically about whether the extended hub on the dually D60 would allow the 7.5" BS of the Hummer wheels to clear. The answer was that it would clear and that several people were running them. Sorry I can't be more help.

bandsaw seems to be the method of choice for most people.

Bandsaw, sawsall, Lathe. I have a friend working on some aluminum beadlocks.
