STRUCTION & FEATURES Tread
CONSTRUCTION
INNER LINER
Inner Tube
A layer of rubber (inner liner) which
replaces the inner tube is stuck to the
inside wall of the high-speed tire. The
inner liner is made of thick rubber, a
material that high-pressure air can not
pass through. The liner can not be Circle Boundary Tire Shoulder
lengthened like other inner tubes, so
when nails are inserted into the tire,
breaks will not be enlarged because Tire Flange
the nails are suppressed to avoid air
leaks. When tire break occurs, the
inserted nails will spring out to make Tube Valve
the tire run under low pressure. It is Tire Bead
very dangerous because the tire
temperature will raise highly to make Tube Tire
tire wobble during riding. Therefore,
riders must be very careful to check
tire pressure and inserted nails before
riding at high-speed.

its function. The fabrics is specially
adopted for the high-speed tire to
keep its air density because air can
not pass through this material. Also,
the fabrics can keep the tire from Tubeless Tire
damage when the tire falls off, and
protect tire from damage due to
friction of wheel rim while riding.
