Michelin MICHELIN Bib Mousse Foam Tube 90/100x21 (M16)

The Michelin Bib Mousse is a foam insert that replaces and eliminates the need for a conventional tube inside your tire. With the Bib Mousse's solid construction taking the place of your tube, you'll no longer have to deal with pulled stems, lost pressure, punctures, pinched tubes, or flats of any kind associated with traditional tire tubes. The Bib Mousse is ideal for off-road use, where it can handle speeds up to 80 mph and has a pressure equivalent of 13 psi, making it ideal for all types of terrain. And with its long 6-month lifespan, you won't have to worry about flats for a while. For off-road use only. Maximum speed of 80 mph and 20 mph on hard surfaces, size equivalents: 100/100x18 = 120/90x18 Michelin M18, 110-120/100x18 = 140/80x18 Michelin M14, 100/90x18 = 1 Michelin M12, 110/90x19 = 130/70x19 Michelin M199, 140/80x18 = Michelin M02, 80/100x21 = 90/90x21 Michelin M15, 90/100 x21 = Michelin M16
