So, my rims say "Tubeless tire applicable" and I read a bunch about running tube vs. tubeless and decided to go w/o a tube. I ordered tubeless tires in 130/90/16 and 100/90/18. I put the front tire on and the tire is sitting in the rut in the middle of the rim and will not jump up onto the outer rim spots no matter what. Tried to strap it, tried water, soap, air, 3 people. Should I just go with tubes? I mean, what would a tire shop do differently? Am I missing something?
