flat tubeless tyre

[EttienneCT]

Hi everyone

 

Been riding for 3 months now recently purchased a 2nd hand 2015 Giant Trance 2 650b.

 

After riding last night found the rear wheel completely flat this morning with the liquid running out. Tried to pump the wheel up, but the tyre is not sealed on the rim and the sludge is causing the tyre to stick to it's self and rim.

 

Being completely new to tubeless, please let me know where i should start to fix the problem or what my options are.

 

Thanks

Go to the petrol station and use their pump. Inflate HARD and leave in the sun for a while, spinning occasionally

You will need to re-seat the tyre. Probably best to remove the tyre, replace the sludge and then seat it with either a compressor or a CO2 cylinder, you need a sudden rush of air to seat the tyres on most rims. Once you have the tyre on and the sealant has been added spin the wheel a bit to distribute the sludge before you try to inflate it. It is important to seat the tyre properly, make sure that the line above the bead is an even distance from the rim lip, if it isn't then pump the tyre more with a track pump and push it around a little until it is properly seated.

 

Why it lost pressure is another story. Check your valve, sometimes it works loose and you can lose air there. Could also be that your sludge had dried up and you got a puncture.

What tyres do you have? Some tyres that are NOT tubeless specific can go down easily without actually getting a puncture. 

Like said above you need a compressor to pump the tyre initially because you need to blast a large volume of air into the tyre quickly and a standard bicycle pump isn't enough. You could also use a "bomb" in severe cases but they sometimes react with the sealant and then you need to change it so only in emergencies use a bomb.

Tubeless can be a bit of a black art and daunting to the uninitiated. All my tyres and rims seat and seal easily without using garage compressed air. A high volume floor pump should work.

 

Chances are you have a rim/tyre combo that is not ideal for tubeless. There are ways around this by trying different tyres. Best bet talk to a decent bike mechanic for some tips and assistance...

thanks guys for the advice. i don't have the connector for the petrol station pump, probably be best if i just go down to my nearest bicycle shop. any recommendations in the Bellville area.
