"if you are willing to take the risk and suffer the irritation of trying to ever get the tubless tire off the rim with ordinary tools in your kit for a road fix or home tire change then have at it"
I guess I just don't see this.
For example, the Michelin Activ 3.50-18 is in the size of the older bikes, yet it is a tubeless tire and by their own instructions can be used for BOTH tube-type wheels AND tubeless wheels. They, do, however, say to use a tube on a tube-type rim with their tire.
But how would removing THIS tubeless tire off a tube-type rim require any special tools? I have changed my tires myself on my '78 R100 both front and rear, and used all tubeless tires (with tubes except for one and it was a tube-type tire) with NO special problems in removing or installing. Why the special tools?
The only problem I have ever had was recently when I installed a Michelin on the rear of my bike, I, nor a local dealer could get it to seat - I think that the tolerances were too tight. I had to go back to a Dunlop, and it worked fine - a tubeless one none-the-less.
My issue is this.
I am not sure why one would want to eliminate the tube in these wheels? If a tubeless tire will work anyway, why not just run a tube inside as Michelin recommends?
