Nuts on inner tubes

[McCabe-Thiele (Ted)]

So going back to the start of this post I have certainly learnt something.

PS Now I know why my sack trolley has a wonky tube valve.

As noted on Ash's response, off road tyres are prone to moving when run at lower pressure, which you need to see before it tears the valve out.

The rears usually have two beed lock clamps to try and stop this happening, but often not tightened sufficiently to be fully effective, you have to winch them down real tight if you want to run low pressure.

An old endure race  mod was to drill a hole on the tyre sidewall to take the valve out through there such that it would then go with the tyre if it rotated in use.

Believe that the moto-gp rears run at about 9 psi static pressure and can rotate to then put them out of balance. Valve not affected as tubeless arrangement.

Didn't guys use talc powder to lessen the issue of a rotating inner tube?

Catching up on my mag reading and saw this....

Well, I learnt a new thing today. Nice thread - thanks for the shared wisdom.

Every day is a learning day J. My mate DodgyRoger (who you know  ) was only telling me in the pub recently  about innies and outies after he was watching one of his favourite late night TV shows.

Are we talking about nipples?

The comment about the endurance bike mod reminded me of what I used to to do with the rear speedway tyre valve Nigel. I use to push it out of the sidewall of the tyre as it made it quicker to change the tyre and because we used to run the rear tyre between 8-14psi depending on how deep or slick the track was. Iwade was always slick but Milton Keynes was always deep. If the valve came out through the centre of the rim it would get ripped out when the tyre 'crinckled' under power during a broadslide. Speedway tyres are now tubeless.

Just saw this on the box of a new Michelin tube I received in post today.

That's pretty conclusive Ash both nuts on the outside (3 including a rider). I must see how mine were fitted when the wheels were rebuilt by CWC.

That said my  tyre was fitted the wrong way round  according to the rotation arrows - they collected the wheel sorted it & delivered it back f.o.c.
