The centre hole on the h2 wheels is to small for my truck. how did u guys with h2 wheels make them fit your 3rd gen

 

You have to have the center hub hole bored out to fit. You can do it yourself using a hole saw or router, or pay a machine shop to do it. I think the hole needs to be 4.775". I really don't remember the exact size. But if you do a search, you will find all types of info on this process.

The reason for this is because the GM H2 has hubcentric wheels; where Dodges are lugcentric.

 

I had a set done with a cnc machine ... tires still on them to 121.5 mm. Fit perfect after.

 

As the others stated above. You need to machine the center of the wheel out to 4.774". I took mine to the machine shop to get them CNC Machined out. Fits perfect and powder coated them black. Cost roughly $20 a wheel to machine the opening where I got it done at.

 

thank u guys for the help i will be taking them to a machine shop tomorrow

 

You may not find a machine shop that will do them. Find a 4 3/4" hole saw use cutting oil. The hole saw will self center on the rim so no problem there. The rims are not hubcentric so machining them to .001" is not important. If you were to buy aftermarket rims you might see that the hub opening on them are about 5". I test fit a $500 rim a month ago(very nice rims) and there was almost 1/4" clearence around the hub. I took one H2 to a couple of machine shops and they could not figure how to chuck them. I have done two sets of H2's with the hole saw and the best part is you do not have to dismount and remount the tires.

 

i was wondering if i would have to dismount the tires. There is no way i am going to pay to have them remounted. Is there any way that they would beable to do it with out dismounting the tires

 

as said above use a hole saw

I think the router method is the best way to do it with the tires mounted, the hole saw method doesnt make a very clean hole...

 

I burned my drill out doing this to the set on my 03. You also have to be careful with the holesaw because even using a drill with the handle on the side the saw will try to walk out of the hole if you aren't careful. If that happens, you will be very unhappy when it walks across the face of your rim... Also make sure you make the hole large enough so that it's not a tight fit on the rear hubs. You may have a very hard time getting them off if it is tight.
I have an extra set of lugs if anybody needs them. You either have to put two sets of lugs on your studs so the second set can hold your caps on or you have to cut your caps down which is a pain in itself.....

 

i used a flush cut 1/2in routr bit when fine BUT I did have to cut a tad more with a rotory grinder to to slip on. But all is well now for my brand new $400 hummer rim and tires. sold old tires and wheels for $500

 

Opened the center hole on mine with the 4 1/2 angle grinder with the guard removed so it would fit in also works better if you have a couple older grinding wheels that are a little worn (fits better) just take off the little lip on the wheel fits perfect. I cut the center caps down with a dremel cutoff wheel. Total cost about $5 for grinding wheels & dremel cutoff wheels, a couple hours in the garage, a few beers it was a hot day out!

 

I have started to do it with the grinder no place around here sells 4 3/4 hole saw.

 

Just keep going round and around so you dont go to deep in one place. I actually sat on my rolling shop stool and rolled back and forth with the tire rolling and basically just holding the grinder still so you dont have to keep turning it completely around let the tire do the work 4 U. If you have a dremel and cutoff wheels you can cut down the centercap urself. I didnt want to pay to dismount, remount, balance, plus machine shop.
