Series 1 Jota cast wheels - inner tube or not ??

all the tyre shops that I know of no longer fit plugs from the outside to car tyres, they remove the tyre and fit a mushroom heeded plug from the inside, the same parameter must surely apply to bikes but even more so, one wheel down on a car is bad enough but on a bike????

The Laverda cast wheels can and do take tubeless tyres, but this is not approved, in Germany, I imagine you could find yourself in big trouble with TUV and type approval. The "inside" edge of the tyre on "proper" tubeless rims has a shoulder to bear on, on non tubeless rims (not specifically Laverda) this is not present. It only works on Laverda cast wheels because the dimensions are very tight, witness how hard the tyres can be to mount and dismount, from memory thin flange wheels are worse than thick in this respect, or did I imagine that?

Your defo not imagining that "witness how hard the tyres can be to mount and dismount" ::)

No difference in stickyness between thin and thick rims, Clem.  Only, the thin ones bend easier... they can be deformed by the tyre bead starting to go over the edge while removing.

I attack old stubborn 20+ year-old tyres with an angle grinder, cut one bead about 1/2 way through, the rest just snaps under tension, easy-peasy.  Stinks to buggery and fills the workshop with smoke, but better than bending an irreplaceable rim.  :o

Seriously doubt that a run-of-the-mill T?V inspector would spot a tubeless conversion during normal test procedure.

Yay! My favourite thread!  Never needed an angle grinder yet, but do have a tyre machine. Laverda rims are the hardest bastards due to a very shallow well, that?s why they are so heavy.  (70000 km on tubeless thick web wheels on the Jota, but don?t tell grants insurance company)
 
Congratulations to all.
3 pages and still going strong.

I put tubes in mine by the way. Corinnes 500 and the cast wheel Electronica which is still in quarantine in Italy.
