Radial tires were invented in 1949 by Michelin engineer Marius Mignol. Radial tires have a particular design that improves safety and comfort compared to traditional bias ply tires. Radial tires are constructed by combining rubber chemicals in a machine called a banbury. Six components, including the tread, ply, belts, sidewalls, liner and beads, are assembled into an uncured green tire. The green tire then undergoes vulcanization, which uses heat and pressure to transform the soft rubber into a tough, durable tire.

2. What are radial tires
The radial tires come to the undustry in 1949 designed by the
engineer Michlin Marius Mignol naming the tire Michelin X. The
radial tires are nothing more than a particular design of
vehicular rim that were invented to improve our safety confort

3. How to build a radial tire?
•Tire construction starts when raw chemical additives such as sulfur, carbon black and solvents
are combined with natural and synthetic rubber. The process takes place in a large machine
called a banbury.
The Green Tire
•The six components (tread, ply, belts, sidewalls, liner and beads) come together on the
tire-building machine. These six components are assembled into what is known as an
uncured, or green, tire in two stages.
Vulcanization
The next phase is vulcanization, the molecular transformation of the soft, gummy green tire into
the tough, and long-wearing, modern passenger tire. The green tire is placed in a curing mold
and is subjected to intense pressure and high heat internally and externally for a specified
period of time.

4. Advantages
of radial tires
• Reliability. The
tread of a radial tire
does a better job of
gripping the road
and provides
improved durability
and maneuverability.
• Protection.
Radials have a thick
shoulder that
protects the interior
from shocks and
damage.

5. Disadventages
of radial tires
A ply layout that
causes the radial tire
to follow a
wheeltrack more
consistently than a
bias ply tire.
Poor transport handling,
since low lateral stiffness
causes the tire sway to
increase as the speed of
the vehicke increases.

6. Importance
The importance of a
good tire lies in the
fact that is the only
means of contact
between the floor and
the car
