100/90 rear tyre on Scootrs tubeless.

[10 inch Terror]

Hi all, has anyone fitted a Raceman 100/90 tyre to a Scootrs tubeless rim and used it on the rear? I've tried it with a Michelin S1 and it rubbed on the casing. I want to make sure before I fit the tyre as it will need to be cut off it it won't work. Any advice gratefully recieved. Thanks Pete.

Got one on mine and it does rub slightly at times.Think mb do a spacer to fit behind cone?
