Spoke with my local dealer The KTM Centre in the UK and KTM are against all this due to probs with the Tube / Tyre prob , i have tried and failed to find an answer on your main thread so sorry IF its an obvious answer

well there are three basic genres of tubeless wheels....

A,,cast/forged/ alloy wheels with machined surfaces

B,,,genuine tubeless rims made of steel or alloy that are void of any item that needs sealing they would fall into several sub-categories:

1,,,steel rims on your car BWOE

2,,,wire wheels with steel/alloy rims that have a place for nipples or spokes to attach to hub ie Moto-guzzi/BMW,Aprilia Caponord use this X-laced spoke technology

3,,,other types use a ''sealed rim with a flange that is part of the extrusion,,and attach it to the hub via spokes ala Gas-Gas trials bikes or riveted metal plate spokes like the old Honda Comstar wheels

C,,, all other wire spoke wheels that try to be sealed for tubeless by a variety of technologies,,ie liquid sealants of all types,,ie:silicone/plumbers goop/ Seal All etc,,,,or special taping systems,,or
special nipple/o-ring systems ,,,,or the new Tubliss System using bicycle tires and tubes to hold the
tire against the bead and seal off the area where the nipples come through the rim

here's another thread with more info on this topic


PS,,the main concern is that you use rims/wheels that were designed and speced for tubeless application in conjunction with a tire that was designed for tubeless application,,our current tubeless technology is the result of a collaborative effort between the wheel and tire manufacturers. it requires tight specs on both their parts
