Rims for tubeless tires?

[PH4]

I have always run tubed tires on my 109s. Is there any problem with running tubeless tires on my stock series rims/wheels?

I was curious about this too, I was told tubeless tires can be run on rims meant for tubes, but there's no safety bead on the tubed rims, im assuming that its not recommended because if you get a flat there's nothing holding the tire on? also the bead helps the tire seat with a good seal, so im thinking it might cause leaks, ill probably be proven wrong on al least one of these things, but i thought i would try helping for once Id also like to see if anyones tried it though because ive got the origional 16s mor my 88 id like to use

I have been running without tubes on standard riveted rims for years and now on 1-ton riveted rims, with no problems what so ever, I know quite a few guys doing the same. The reason for me taking out the tubes is simple, I got more punctures with the tubes (no foreign objects, probably poor quality tubes although brand new) in tubeless tires. The reason according to a tire-specialist is that the tube is rubbing against the small lines on the inside of the tubeless tire, and since it's nearly impossible to get hold of tubed tires nowadays, he recommended to loose the tubes.

You can have problems though, if you let out a lot of air and run tubeless on tubed rims, because of the missing safety bead, but I have never experienced any problems.

Do you have welded or riveted wheels? Welded wheels are usually for tubeless tires, while riveted are for tubed.

A lot of people run the original rims tubeless- the rivets usually hold air and if they don't you can paint them, galvanize them, or put bead seal on them, then install a tr-15 valve stem fort the 5/8" hole. They lack the safety bead bump but so do some other "tubeless" rims. IIRC American 16.5s often lack safety bead bumps.

On the other side of the pond, running without tubes is frowned upon.

In short, running without tubes is less problematic. New truck radials are not smooth on the inside and with generate a lot of heat and make this type of failure likely. Tubeless punctures are easily dealt with in the field with a cheap repair kit and compressor. As for the safety bead, I have seen tires fly off with them so I am not convinced of that argument. I have 1957 rivetted rims holding air with no problems. I put some sealant on the inside as an extra insurance. I have seen 90's era GMC heavy truck rims with rivetted construction, so I am not buying that argument either.

can someone please explain the reaction in this video?

Seating the tire bead

the easiest way to seat the tire bead is with ether, and a match.

[RoverForm]

so you spray some ether on and around the bead, then light it? does the flame cause the ether to suck in air? because in the video it looks like the tire inflates also...

[bkreutz]

When you light the ether (lighter fluid works too) it expands rapidly seating the tire (and inflates it too). This is the "I don't have a compressor" method. (works quite well though)
