it was a puncture but after taking the tyre off cleaning everything and

refitting it i cant find owt wrong with it, just wondered if i am running it

a bit on the low side 4.5psi.

jsp

FF its got a michelin on and its tubeless

You can run them at 2 or 3 psi without problems - they'll generally stay on the rim even when punctured.

Unless there is something wrong with your particular tyre you must have just been unlucky as there is nothing else I can think of that would cause it to come off the rim, unless maybe it was never seated properly in the first place

how offten do you check your pressure

if it had crept down yot may not have noticed

i run 4 psi back 7 psi front but check regularly

Take off the chain and spin the back wheel to make sure it is true and you havent got any dings in the rim. Maybe you caught it on something and didnt realise.
