wheel question

[rookie]

When i remove the run flats do i need to get new o rings or gaskets for the 2 piece rim or can i reuse the same o rings

You can reuse..I have. If you can get the rims a parts and not disturb the oring that's even better.
i will put RTV in one or both channels, then let it dry after assy for 24hrs before I air up.
but reusing is not 100% guarenteed to seal....but neither is new if done wrong.

The ability to reuse an o ring has a lot to do with how well its put together. If the o ring is still pretty much round I say go for it. A lot of times they wont get bolted down right and part will squirt out of the channel screwing up the o ring. It tends to mashed flat making it un usable. Some times a thin layer of silicone or rtv in the channel the fitting the o ring above it to cure will help fill voids. You should tighten a combat wheel just like the lug nuts 12-6-9-3 o clock but dont run them down tight. You need a fairly even compression of the o ring.

I have had great success using tire bead sealer from NAPA on the O-rings! Aired them up after 30 mins.

O rings cost about $4 or less, are you willing to risk your vehicle for $4? I've reused O rings in the past when I had to but for cost it doesn't make sense not to install new ones when doing wheel work.

Or, having to break down the tire and rim again. If out in the sticks, I may try re-using, if working in the driveway, use new.
