The simpler things get the more difficult the choice?
I've had tube creep on a 175cc bike with around 16psi .. it is not the HP that count it is the torque .. after first gear and clutch slip! And you can get front tube creep too.
I've riddeen on flat tyres .. not much different to riding in sand.. and if your doing both at the same time! More modern tyres can have very stiff side walls that mask flat tyres were well.
The inner tube stem will stay put by the action of the air pressure.. there is not much else acting on it. If the tube has crept to the point where the tube cap is holding it from going into the rim .. well it is well pass the point where the the tube would have been ripped out of a stem fastened to the rim by the nut. I've seen people riding with no stem visable .. it had dissapeared inside the rim... with the cap!!!
