This document discusses the structure, properties, types, and functions of tires. It begins by defining a tire as a cylindrical component made of multiple layers that provides traction, supports vehicle load, absorbs shocks, and enables smooth driving. It then describes the main parts of a tire including the tread, sidewall, bead, plies, belts, and inner liner. The document goes on to explain the main types of tires such as tube tires, tubeless tires, and differences in carcass construction including cross-ply, radial, and bias ply styles. It finishes by listing the key functions of tires and providing diagrams of standard tire dimensions and specifications.

3. TYRE
 ATYRE IS CYLINDRICAL COMPONENT MADE UP OF MULTIPLE LAYERS
OF MATERIALS. ITS PRIMARY FUNCTION IS TO PROVIDE TRACTION
AND SUPPORT VEHICLE LOAD, ABSORBS SHOCK AND PROVIDE
SMOOTH SAFE DRIVING.

5. STATIC AND DYNAMIC PROPERTIES
1.The outermost part of tyre that contacts the road
surface. It consists of a patterned design to enhance
grip and traction.
2. Sidewal: It often contains important information
such as the tyre size, type, and manufacturer’s
specifications.
3. Bead: The bead is the inner edge of the tyre that
securely attaches to the rim of the wheel.

4. Plies - Tyres have multiple layers offabric cords known as plies. The plies
provide strength and stability
5. BELTS - provide additional strength, stability,and resistance to punctures. They
also help maintain the tread's shape andprevent it from excessive flexing.
6. Inner liner - It acts as a barrier to retain air withinthe tyre and prevent it from
leaking through the tyre structure.
7. Casing: The casing refers to the entire
structure of the tyre, including the plies,belts, sidewalls, and tread

7. TYPES OF TYRES
TUBE TYRE
A tube tyre consists of a tube that is filled
with air. This tube is fitted between the rim and the tyre
itself. The valve of the tube is attached to the rim hole
and is used to inflate the tyre. So, when a sharp object
pierces the tyre, the air in the tube will find its way out
fast.

9. TUBELESS TYRE
 A tubeless tyre looks like a standard tube-type clincher tyre but
requires no inner tube and, once ‘seated’ (seating is the process of
snapping the beads into position), it forms an airtight seal with the
rim. A valve just like the one you’d find on an inner tube is fitted
directly to the rim.

10. TUBELESS TYRE

11. CARCASS TYPE
 CROSS PLY TYRE
Tyre consist of carcass layers made from nylon cord. They are placed
diagonally across each other in the tread and the sidewalls, at an
angle of 55 degrees. Multiple rubber plies overlap each other and
they form a thick layer, resulting in less flexibility which can make it
more sensitive to overheating. Therefore all high speed Tractor tyres
are of Radial construction

13. RADIAL TYPE TYRE
 A radial tire is a particular design of vehicular tire. In
this design, the cord plies are arranged at 90
degrees to the direction of travel, or radially.
 Radial tires consist of one or two casing or sidewall
plies comprised of either fabric or steel cords and
aligned 90 degrees to the beads. Tread plies are then
added for directional stability and puncture
resistance.

14. RADIAL TYPE TYRE

15. BIAS TYPE TYRE
 The carcass of a bias tyre is made from ply cords in layers
arranged at an angle. The layers are placed so that the cords
create a criss-cross pattern. The whole structure is uniform
throughout; the crown and sidewalls of the tyre have similar
mechanical properties.
 Bias Ply tyres have a sidewall that runs diagonally from bead to
bead, with multiple layers of rubber-coated fabric plies that run
at angles to each other

17. FUNCTIONS OF TYRE
 LOAD BEARING
 TRACTION
 ABSORBING ROAD SHOCKS
 STEERING CONTROL
 NOISE REDUCTION
 STABILITY OF VEHICLE
 SMOOTH RIDE
 PROTECTION TO VEHICLE AND CHASSIS
