REAR TYRES

R1 agriculture tyre

These tyres are known as agricultural tyres and provide

the best traction for farm field condition

R1W (deep lug tyre)

Tyres have deeper lugs that provide increased traction in

wet, sticky soil conditions. Distance between the lugs & lug
height is more to avoid the sticky soil deposition.
REAR TYRES

R2 TYRE

Tread type used typically crops grown in wet muck or flooded

field. Tread depth of R2 tires is approximately twice as deep as
R1 tyres.

R2 tires also have the widest spacing between lugs to allow

mud to shed easier.

R3 TYRE

These tyres have a very non-aggressive pattern and are thus a

good choice for work on golf courses, lawns, etc.

R4 TYRE

They can handle high weights and pavement. They are ideal

Parts Of Agriculture
Tire
BEAD
Beads Anchor the tire to the rim and allow
the tire to stay "seated" on the wheel.
BEAD FILLER
Bead Fillers stabilize the lower sidewall by enveloping the
bead and extending up tin the sidewall to maximize stability,
steering response, and case durability.
 INNERLINER
Liners protect the cord body by insulating the tubes from the cords. Liners
are essential for resisting air and moisture permeation.
 BELTS
Belts determine the shape, or footprint, of the tire. Belts work in conjunction
with the cords to add stability and strength.
 TREAD
DESIGN
Treads serve to interact with the soil or paved surface and provide traction.
Tread design varies between tires to maximize traction and resist wear and
tear.
SIDEWALL
Sidewalls are made of flexible rubber and provide lateral stability. The sidewalls
keep the body plies and inner liner of the tire protected from stubble and debris.
Sidewall flex is a big factor in deciding what tire is right for what job and what
piece of equipment.
UNDERSTANDING TIRE SIZE
 LUG
BUTTRESS
Lug depth is important for traction. together with the lug buttress, this
component provides tread stability.
 BODY PLIES
Cords run radially from bead to bead and determine the strength of the tire,

 What are the
material use to
production

23
The tyre’s basic material is rubber, and it is here that the differences begin between a top-
quality and a lessor quality tyre.
Natural rubber (latex) comes from Hevea tree sap and has irreplaceable qualities: it is resistant,
elastic, impermeable and reacts excellently to vulcanisation.
It’s the quantity of natural rubber used which will give the tyre is characteristics, such as
resistance or elasticity.
Discount tyres tend to be made of synthetic rubber which is much less resistant and durable
than the original version.
Companies like Bridgestone have their own plantations in Liberia so as to be able to
incorporate a larger share of this pure latex in their tyres and to ensure the ecological and
sustainable management of natural rubber.

These defects can affect the tire's

BREAK AT THE END
OF THE
REINFORCED PLY
When you notice a fissure between the bead
and the sidewall, even if it is very slight, it’s
often too late. The separation has occurred at
the level of the ply turn-ups just above the bead

BREAK IN
THE BEAD
WIRE
A break in the bead wire generally occurs during
inflation at the time of the “water hammer effect”.
This is the moment when the pressure is sufficient
within the tyre to push the beads into their end
position in one go.

Advantages of Agricultural Tractor Tyres
• Traction: Tractor tires are designed with deep, aggressive treads that provide excellent traction on
various surfaces, including mud, gravel, and fields. This traction is crucial for efficient plowing, tilling,
and other farming tasks.

• Stability: Wide and robust tractor tires offer enhanced stability, especially when operating on
uneven or sloped terrain. This stability helps prevent tipping and ensures safe operation.

• Load-Carrying Capacity: Agricultural tires are built to handle heavy loads associated with
farming equipment, allowing tractors to carry implements and machinery without compromising
performance.

• Versatility: Tractor tires are versatile and can be used in a wide range of applications, from
Cont.

• Flotation: Larger tires with lower inflation pressures distribute the weight of the tractor more
evenly, reducing soil compaction and minimizing damage to the fields.

• Durability: High-quality tractor tires are engineered to withstand the demands of rugged
agricultural environments, including exposure to sharp objects, rocks, and abrasive soils.

• Customization: Farmers can select tires with specific tread patterns, sizes, and load-carrying
capacities to match their specific needs and equipment.
Disadvantages of Agricultural Tractor Tyres

• Limited Speed: Tractor tires are designed for lower speeds compared to regular
automotive tires. This limitation can result in slower travel times between fields or
farms.

• Tire Wear: Heavy loads, rough terrain, and harsh conditions can lead to accelerated
tire wear, necessitating more frequent replacements.

• Fuel Consumption: The deep treads and sturdy construction of tractor tires can
contribute to increased rolling resistance, potentially affecting fuel efficiency.

• Vibration and Comfort: The robust nature of tractor tires can transmit more
vibrations to the operator, leading to reduced driving comfort during long hours of
operation.

• Maintenance: Tractor tires require regular maintenance, including proper inflation,

alignment checks, and timely repairs, to ensure optimal performance.
Cont.

• Specialization: While versatile, certain tasks may require specialized tires (e.g., flotation tires for
wet fields, narrow tires for orchards). Using the wrong tire type can impact performance.

• Cost: Quality agricultural tires can be costly, especially for larger tractors or specialized
equipment. Replacing multiple tires can add to the overall expenses.

• Environmental Impact: In some cases, the use of large and heavy agricultural equipment with
tractor tires can contribute to soil compaction and disruption of natural ecosystems.
