Did the web sight with the wheel and there numbers help with your question. I have combat rims and matched my wheel number to the web sight and got the correct ones at 1/4. I don't believe in running a bigger O ring than what the wheel calls for. Double check both half's of mating service and clean them out good with air and use tire soap on O ring and tire. My new combat wheels came with two regular nuts holding the wheel together. I use the two regular nuts across from each other to pull the two half's together evenly. Then use the distorted nuts on the rest of the studs taking them down to snug. I replace the two regular nuts with the last two distorted nuts and tighten to specs.Got it together a couple days ago and tested it, worked good up 50psi and then started leaking. No better than what I'm already dealing with. I suspected it might do that since I saw a few spots that looked like it might not maintain contact with the two sealing surfaces. I will get the o-rings but had a question before I ordered enough for all the rims. I've seen two different styles of sealing surfaces, the tapered rim seats on Ken Nelson's rims (Nelson studios on YouTube) and the type on this one rim I already have apart that pinches the o-ring and holds it in place. Ken said that his rim had a 5/8-18 studs, whereas all mine are the 3/4-16 studs. Can I count on all my rims being the same as the one I've already pulled apart? And 1/4" seems a bit small for an o-ring on this rim, do I need the 3/8" ones instead?
Thanks
