Can anyone recommend a tire shop in Chiang Mai that can install tubeless tires without tubes? From installation through three flats with my Michelin Pilot Sporty tires, all four shops have said "can't do" for some reason. I'd like to be able to repair the tires on my own when out riding in the hinterlands, so tubeless is the way to go. Getting a new rear tire on Monday since I shredded it on glass a few days ago so want to get rid of the tubes on both ends. Any recommended shops?
