Seating a tubless tyre with gas

[DuncanCT]

So I was having trouble getting the bead to seat on my tyres. First time trying to seat such wide tyres (29x3.0). Compressor didn't work and have seen this done before with vehicle tyres.
 
Worked really well albeit after a couple of attempts. And before anyone says any thing, I'm sure MAPP gas isn't the best option as it has quite a hot flame but it was all I had.

 

Edit: Don't do this if you have heat sensitive rim tape. Like Stans or anything thin like that.

I have seen this done on bakkie tyres. Did the heat not have any adverse affects on the tape? Also did you add the sealant after seating or was that with it in?

[fanievb]

next time, try using some soapy water on the bead

The tyre gets slightly warmer but no more than sitting in the sun I think. Also no sealant yet. Going to see if I can just crack the bead and add sealant.

The rims are really wide, unnecessary wide I think, id of 46mm. So hard to get the tyre just to contact the rim at all.

Don't bother cracking the bead it'll make life a mission. Just remove the valve core and use a 60ml syringe to put sealant in that way

Syringe and a hypodermic needle. Thank me later.

No such thing...

Nice! I have seen this before but sommer with some good old deodorant spray! Definitely worth a try for next time.

 

The only issue I ever have with doing tubeless is getting rid of that darn tubeless valve leak! farkkkk!!! Have started resorting to contact glue which seems to solve the issue...

I've @#%&ed myself here. Made my own tubeless valve out of a road bike tube without a removable core. Generally don't like removable cores because they always come out when you don't want them too.

Do you go strait though the side wall with the needle?

 

No such thing...

Think this could be a whole nother thread on it's own. Listed to an interesting pod cast on the subject that suggested the ratio of 2.2 from tyre width to rim width is good. If some one has a 35mm rim to lend me I'll mount the tyre and compair shape to the id 46 rim.

Yup, old 4x4 trick. Propane or deo work equally well.

[dave303e]

you get bead blasters now for the 4x4 and quadbike tyres... but for bicycle a big compressor will work, so just amble to nearest petrol station and abuse theirs.

Sidewall is generally where a tyre casing is thickest, so yes.

Won't the beads get stuck in the thin needle?

[lechatnoir]

Wonder what sort of pressure you can get up to, and won't too much blow your tyre off the rim? Leaving you with a big skrik and a wonderful YouTube moment we can all enjoy

depends on the sealant... hypodermics are pretty substantial though.
