fitting inner tube

Drummer99 · Nov 6, 2015

I am fitting the inner tubes on my 74 commando they are michelin airstop tubes They come with a washer and 2 nuts can anyone tell me how the nuts and washers are applied does the one nut hold the washer and then installed inside the rim ? and then one nut holds the inner tube from the outside. Would appreciate some guidance on this
Thx Jack

Yes. You are correct in your thinking. The box doesn't show this, & lots of people fit the washer on the outside. Not really sure why Michelin use these dished washers. Continental make very good quality tubes & don't fit them.

This may not be correct per Michelin, but I put the washer on the stem inside the rim, and only use one nut as a locknut under the valve cap. That way if the tube should shift inside the tire/rim the valve stem would no longer be pointing straight out, and you could spot that visually. That's an old enduro set up tip.

That is how I always fit them, however, I know others prefer to screw the outer nut up against the valve cap.

With the added advantage that it doesn't rip the valve out of the inner tube leaving you stranded.

+1
except after the tube is installed and aired up I throw the outer nut in the bin and save it for something useful.
