Hummer wheels on 05 2500?

[Bertram65]

Carli Suspensions sells the light bar. It is one beefy unit. They have a special running on the old style that mounts where the tow hooks go. You have to lose the tow hooks. I don't care as my plow frame already made me lose the tow hooks.



They have a new design that allows you to keep the tow hooks. Smoking deal on the old style one.





Back to the Hummer wheels...



The can be lugcentric. You don't necessarily have to have a tight fit on the center hole. The nuts are conical. I used to think they were hubcentric but with conical nuts I'm not sure it matters.



With that said you can save yourself time and money by using a HoleHawg drill that runs low rpm and a 4-3/4 hole saw. Yes that's right I'm not crazy... many have done it this way. That size hole saw fits perfectly into the depression. Turn it on slow and it cuts right through. Than you use a die grinder or a RotoZip with a burr cutter or coarse sanding drum and slightly enlarge it evenly to fit without interference.

Wow, after all the aurguing, what made you change your mind and agree they are lug centric now?

Every so often I open my eyes :-laf



I still can't explain why Dodge makes the stock aluminum rims and the axles hubcentric AND lugcentric.



Why would they spec precision machined axles and precision machined wheels when only the lug nuts do the work?



I'm no longer standing behind any conclusion on this. I'm just confused.

Since both the hub and the wheel have to have SOME dimension, where is the extra cost to spec one to fit close to the other? It doesn't cost Dodge any more to spec that hole at 4. 774 than it would to spec it at 4. 780, would it?

With that said, I still think there is value in having that hole machined and not gawed on with a hole saw. I got the chromed H2 rims and tires with 20 miles on them for $800. To me, it was worth the $150 to have a shop deflate the tire, machine the hole and keep the rims shiny. The cost of the saw, arbor, drill rental, sanding drum/roto saw/file or what ever is used is going to come close to this price anyway. This way, they are perfect and look wonderful.





BTW, someone pointed out that by adding a second nut to the studs, our center caps fit perfect without needing to be trimmed. Since the; cap will hold the second nut from spinning, there's no need to torque them tight to the first nut either.

Before I took mine to a wheel specialty shop to have the tires dismounted and the centers machined, I called several other tire shops and asked them how they mount wheels for tire balancing. Universally the reply was on the centers.

So, if you open up the centers of the H2 wheels with a hole saw or a die grinder or whatever, the centers will never be concentric to the wheel OD and you're not going to be able to balance new tires.



Just my 2 cents.

Some of the better machines use the lug holes or have adaptors.



I didn't remove the tires... . same air in them that GM put in them the whole time I ran them.

Have seen wheels where the center hole was opened with a hole saw? how can you say it will never be concentric? it leaves a perfectly round hole centered on the wheel, the lip the H2 wheels have allows the hole saw to be started in the hole so it self centers. As far as dismounting the tires and then having them remounted, it is very unlikely you can get anywhere close to as a good a balance as how they come from GM, just look at the amount of weight on them if you have them balanced at a local tire store compared to what they origionally had on them. The machine GM uses takes into account the way the wheel is balanced as well as how the tire is balanced and then puts them together so a minimum amount of weight is used.

Since the hole is very close to the center of the wheel and relatively small compared to the overall size of the wheel, and the type of material and thickness at the flange, I dont believe a reasonably rough, off center, enlarged hole, would have a huge effect on balance.



GM does not exclusively own those type of tire balancing machines. My local performance shop used one of those on my Toyo/H2 setup just last month. He explained how it worked exactly the same... . takes all forces into account to calculate the minimum weight requirement.



First tire required ZERO weights. Worst tire took 2 oz.

I did not mean to imply the balance would be thown off by changing the center bore whichever method is used.

As far as those tire balancing machines, they are not very common, for instance NTB and national tire do not have them, it would be great if they were available everywhere.

What is the backspacing on the stock wheels?

No one has told me if these H2 wheels will rub under compression yet with 35x12. 50's.
