Tubliss is a full circumference pneumatic rim lock that secures the entire tire bead to the rim, completely eliminating the use of a conventional tube. A weight savings of up to 3 pounds per wheel instantly translates into less rotating weight and increases acceleration. Eliminate flats from pinched tubes. Replaces old technology with a stronger, modern and efficient system. Even if you get a flat, the bead stays seated to the rim. Improved traction. Tubliss secures the bead so securely that it allows a tire pressure range of 5 to 25psi for improved straight-line traction. Without the weight and friction of a conventional tube installed, tire temperatures are greatly reduced. This also eliminates tire pressure increases during the course of a moto.
