I wrote to Michelin about the ride-on product and this is their response:
"Thank you for the interest in Michelin motorcycle tires Khalid.
While Michelin Motorcycle does not recommend the introduction and use of any sealant type material in its tires, the use of this material, by itself, does not void the warranty. However, if a tire is rendered unserviceable due to the introduction and use of this material, warranty coverage would be void under the heading of abuse.
We do not recommend the introduction and use of any sealant type material in our tires because some of these products may cause damage to the inner liner. The long term effect of these products is unknown (chemical reaction when exposed to pressure, temperature and time).
Because some of these products may be flammable, we strongly urge you to advise a tire dealer of the use of these products before having the tire and wheel serviced. Failure to do so could lead to serious injury or death.
Please refer to the warnings and instructions provided by the manufacturers of these products regarding their use.
I trust this clarifies Michelin Motorcycle's position on this issue and that the information that I have provided will be helpful to you.
We appreciate your business and thank you for choosing Michelin.

not a clear cut but I think they want to be on the safe side and rather not recommend it
