Tire tubes

Stev, That is what I thought. Thanks for the reply.

As I understand it, the combat rims need the flaps, true split rims do not. If one lives in Western Oregon, or Western Washington, or plans on fording creeks & other bodies of water, it would be a good idea to use flaps if you are using tubes.

I also have mounted tires to true split rims on semis, & other heavy equipment & still have all of my fingers & toes. IMHO, unless it is done wrong, they are no more dangerous than "safety" rims. OTOH, supposedly they do not like to be underinflated. If they get low on air pressure, supposedly, the ring can become unseated & at the next inflation it could fly off. I have only heard this from folks who are afraid of split rims & never from folks like Uncamonkey, who were/are in the industry.

I have mounted hundreds of aircraft tires which are like combat rims in that the rims split in the middle. Some use flaps & some do not. Flaps add weight, which is a big no-no on aircraft. I assembled them according to the aircraft manufacturers publications. I never pinched a tube & I never had a leak.
