In my area motorcycle shops, as a rule, do not repair punctured motorcycle tires regardless of whether the puncture is in the tread or sidewall, tubeless or tubed, two seasons old or one day old. Strangely enough some of the automotive tire shops will repair a motorcycle tire if the puncture is small and not near or in the sidewall. I am located in Ontario, Canada. I know tire technology has come a long ways since I started riding over 40 years ago. The same applies to tire/tube repair materials as well. Collectively riders and drivers used to fix flats without reservation, so why the refusals to fix a flat now? What is the experience of riders in other countries?
