Tires come in various types depending on their intended use and weather conditions. The main types include summer tires, designed for warm, dry conditions with soft rubber for grip. Winter tires have deeper tread and harder rubber suitable for snow and ice. All-season or all-weather tires are meant for year-round use in moderate climates. Other specialty tires include run-flat tires that can be driven short distances on a puncture, and performance tires with stiff sidewalls for handling but less durability. Tires are also classified according to their size, speed rating, tread pattern, and materials like rubber, fabric, and silica.

3. What is tyre ????

4.  A tire (U.S. English)
or tyre (British English) is a
ring-shaped vehicle
component that covers
the wheel's rim to protect it
and enable better vehicle
performance. Most tires, such
as those for automobiles and
bicycles,
provide traction between the
vehicle and the road while
providing a flexible cushion
that absorbs shock.

5.  On what basis should tyres be classified…?

6. Tyre types and classifications
 Sizes
 EU labelling
 Tread
 Season of use
 terrain
 Speed rating

7. Tyre materials
 The materials of modern pneumatic tires are
synthetic rubber,
natural rubber,
fabric
carbon black
silica
 They consist of a tread and a body. The tread
provides traction
 body provides containment for a quantity
ofcompressed air.

9. SUMMER TYRES
Built with a soft and
grippy rubber compound
In most instances, will
become nearly useless near
or at the freezing point
They will be noisier
Recognized by its H or V
speed rating and typically
more aggressive tread
pattern
They also expected to
expertly disperse deep
water.

10. WINTER TYRES
 designed specifically for
the snow and ice covered
roads, so when
temperatures decreases
these will surely help on the
tricky road surfaces.
 fine block design with
grooves that are deep ,
also come with spikes,
the rubber compound is
perfect for low
temperatures .
They are very popular in

11. WET-WEATHER TYRES
 have a specially designed structure
making them better adapted for their
application
 are cut or moulded with
patterned grooves . This allows the
tyre to quickly displace the water
between the ground and the rubber
on the tyre. As a result hydroplaning
does not occurs.
 also made from
softer rubber compounds to help the
car grip in the slippery condition.
 larger in diameter and smaller
"footprint" reduces the chances of

12. ALL SEASON TYRES
Commonly referred to as a Touring all-season:
Are of a harder compound with softer
sidewalls
• quieter than any type of performance
tire
Designed to last a long time
Can be used on wet, dry and, to a
lesser extent, snow covered road
surfaces.
have a good ability for water
evacuation
Typically sport a “T” speed rating

13. ALL TERRAIN TYRES
 tyre tread patterns give stability
when travelling over rocks, sand and
dirt.
have improved traction, greater
gravel wear resistance and decreased
stone retention.
 provides exceptional on-road
handling, with good driving comfort and
low noise.
 has a multi-layered steel cord belt
and an extra rubber layer fitted
between the belts.
offer good versatility by offering

14. RUN FLAT TYRES
designed to resist the effects of
deflation when punctured, and to
enable the vehicle to continue to be
driven at reduced speeds (up to
55 mph (90 km/h)), and for limited
distances of up to 100 mi (160 km).
 contains an extra lining within the
tire that self-seals in the event of a
small hole due to a nail or screw.
 the loss of air is prevented from
the outset such that the tire is either
permanently self-repairing or at
least loses air very slowly.

15. PERFOMANCE TYRES
This type of tire is conceived for
the utmost levels of grip .
:Will excel in both wet and dry
conditions.
Are characterised by very stiff
sidewalls for better cornering
abilities and crisper handling.
Will not work in cold weather
because their compound is
designed to work at higher
temperatures.
Will wear out much faster
because they are intended to be
stickier and will be noisier

16. TUBE

17. TUBELESS

18. ECO TYRES
By introducing silica to a tyre
compound the previously
impossible is made possible.
it can absorb different amounts
of energy at different frequencies
for fuel consumption and grip.
 tyres maintain the correct tyre
pressure and making allowances
for varying speeds and different
driving characteristics, Eco-tyres
offer a 20% reduction in rolling
resistance which equates to a
5% fuel saving.
