. HIGH-SPEED TIRE
HIGH-SPEED TIRE CON-
STRUCTION & FEATURES
CONSTRUCTION
INNER LINER
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
lengthened like other inner tubes, so
when nails are inserted into the tire,
breaks will not be enlarged because
the nails are suppressed to avoid air
leaks. When tire break occurs, the
inserted nails will spring out to make
the tire run under low pressure. It is
very dangerous because the tire
temperature will raise highly to make
tire wobble during riding. Therefore,
riders must be very careful to check
tire pressure and inserted nails before
riding at high-speed.
•Tire pressure
•Tire deformation and damage
•Tire groove depth and abnormal
wear
Tire Depth: Front : 0.8mm
Rear : 0.8mm
•Imbedded metals, stones, or other
foreign matters
The bead base where tire and rim
contact is wrapped by rubber fabrics
called tire bead in order to reinforce
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
damage when the tire falls off, and
protect tire from damage due to
friction of wheel rim while riding.
