Well. The tubes have metal stems. And a conical washer with nut at base of stem which clamps stem to rim and is inside the rim. Outside the rim you have a second stem nut. Thus you have two options with 2nd nut. 1) leave the outer stem nut loose dirt bike style so you can visually check if the stem begins to angle which indicated the tyre is slipping on the rim. Slip is usually the result of running low pressure - planned or not - without rim locks. 2) tighten the outer valve stem nut against the rim like it came from the factory. if you run low pressure you won’t know the tyre is slipping until the stem rips out of the tube for a fast flat. But we have TPMS. So option 2 Friend on 1090 has run Sykik for two years with a trip to Baja and back. Another on T7 has run Sykik for a year. No problems.
