a couple years i had new tires put on t 140 with new tubes.
couple days ago
the rim lock pinched the tube
With respect, if a rim lock really pinched the tube after two years, the rim lock cannot be the problem, something else is wrong and you're missing it blaming the rim lock.
Fitting a tyre and tube on a rim with locks is easy:-
. Put the lock between the rim and the rim tape (you did check new tapes were fitted with the new tyres and tubes?). Saves weakening the tape with holes for the lock threads and the tape holds the locks in place.
. Screw each lock nut just on to the end of the lock thread.
. Fit the tyre on one side of the rim. As the "spoons" (or the fitting machine) get close to a lock, simply push on the end of the thread to move the lock into the tyre - the tape'll hold the lock in position in one direction, the nut on the thread will stop the lock dropping into the tyre.
. Fit the tube. The tape is holding the locks against the rim so they can't pinch the tube (you are putting a little air into the tube to give it shape?).
. Fit the tyre on the other side of the rim. Again, as the spoons or the fitting machine get close to a lock, simply push on the end of the thread to move the lock into the tyre - the tape and the tube'll hold the lock in position.
. Seat the tyre in the rim, set the correct pressure, fit the rim lock washers and tighten the nuts.
what do guys use as tire lube ?
Whatever the tyre fitter uses.
I took the rim locks out 20 odd years ago and never had a tyre creep on the rim.
Just keep the pressure up where they should be.
How do you do that when you have a puncture?
Cure: Remove Locks. Place trash can about five feet away.
This is a good cure if you never have a puncture on the move afterwards. Otoh, if you have a puncture on the move, my personal, first-hand experience is having one in a wheel with rim locks is infinitely-less underwear-staining than having one in a wheel without rim locks.
