Tires ~ Converting tube to tubeless type.

[Aussieflyer]

Alain,
our CB1100 spoked rims have safety bumps on the inside of the rim such that the tyre should not easily fall inside the rim ... which would be a huge issue for a tubeless tyre! These bumps are a slightly raised surface that runs around the rim inner just to the inside of the landing area where the tyre bead sits. This feature is a common method for the safe 'seating' of tubeless tyres. After sealing the spoke nipples in the rim a tubeless tyre should install and operate safely on these rims. I took the gamble and converted my spoke wheels to tubeless tyre a couple of years ago. So far no issues on the two sets of tyres I have used over the past 5 or 6 thousand Kms.
