Has anybody using tubeless had a problem with bubbles forming under the tread? I mean a bulge, but one you can press on it and feel the inner part of the tire. I guess itís a separation of the tread from the rest of the tire? Iím wondering how common this is. The wheels are Mavic Crossland, if I read the sticker right, and Maxxis Lust tires front and back. Day before yesterday I noticed one on the rear and one on the front. Today when I checked the one on the rear was gone and now there are two on the front. Maybe the Stans fluid glued the back one down? Iíve been looking for an excuse to replace both with something not knobby so hopefully they will get me to work and the bike shop this weekend
