Latest 4WD Tyre Technology

Latest 4WD Tyre Technology


If you spent as much time researching
tyres as you do when buying a car you would always choose Cooper tyres. Cars
have come a long way since they were first invented. They were hard to control
and didn’t even have brakes. Today cars are lot safer and reliable then way
back then. ABS braking, airbags, traction control even seatbelts and air
conditioning are all improvements made over time that we now take for granted.
There’s a massive difference among car brands and models and it comes down to
technology. Well just as with cars not all tyres are the same. They look similar
but there is a massive difference in technology and that matters. Your tyres
are the single most important safety feature on your vehicle. So take a closer
look at the difference the latest generation in tyre technology makes to
safety, stability, strength, performance and value for money. We’d like to help
you get more involved in choosing your next set of tyres. You can work out
whether a tyre has the latest generation technology by looking at three things –
the tread design, the way the tyre is built or it’s a “carcass”, and the
materials used to build it it’s compound. All you need to remember is “TCC”. That’s
“Tread”, “Carcass” and “Compound”. Right now let’s look at tread designs for four-wheel drive tyres. You wouldn’t wear hiking boots to work, and you wouldn’t wear work boots to the beach. A tyre’s tread pattern works the same way so it makes
sense to understand whether a tyre will be safe, stable and represent value for
money. In a nutshell whether it suits the way you drive, the places you go and the
value you are looking for. So let’s take a closer look at the features of tread design that represent the latest generation in tyre technology. The most obvious difference in four-wheel drive tread design is Cooper’s famous deeper treads. You don’t have to get this far into a tyre to see the difference. You
can use any type of measuring stick to measure a tyres life expectancy by
comparing tread depth. The more tread the longer the tyre will last. Better
still ask your retailer to measure the tread depth of all tyres you’re
considering, and take a closer look. Ever wonder what these tiny cuts are?
They’re called sipes and they reduce slipping in the wet. As the tread comes
in contact with bitumen, the sipes expand and pump water out from under the
tyre, giving you more grip. Cooper’s latest generation Micro Gauge
Sipes are thinner. The benefit of the thinner sipe is that it can be cut
deeper into the tread block, giving grip all the way through its life not just
the first 20 or 30 thousand K’s. Thinner sipes also play a vital role in
performance off the bitumen helping to prevent stones from getting trapped and
drilling into the tyre. This improves wear and avoids tread damage. Cooper also employs other anti-stone retention technology across their four-wheel drive
range. Sawtooth grooves and serrated edges create a biting action for
traction and helps throw out stone and debris. To help prevent tread damage. And if that’s not enough, raised rubber ribs and angled groove walls work together to
eject stones and gravel to maintain grip. All this technology reduces the risk of
stones and gravel cutting and chipping away at your tyres. Here on the tyre’s shoulder you’ll find the “Flex Groove”. It reduces resistance by dampening the
impact of uneven rough terrain and improves sidewall flexibility, especially at low pressures. It means more safety and off-road grip. Maintaining a firm grip off-road can be
challenging especially in muddy conditions. These little pockets are
called mud dimples and these larger scoops create air pockets to prevent mud
from sticking between the tread blocks. Together with Cooper’s unique angled
shoulder scoops they help traction by clearing mud out the tyre faster. “WHOAH!” Right now let’s look at carcass construction for four-wheel drive tyres. When you build a house you make sure the foundations are strong and suitable for
the construction that’s going on top. It’s the same with tyres. You might be
surprised to learn that while the tread is critical it’s the carcass that
accounts for up to 70% of the tyre’s performance. What you can’t see under the
tread is a foundation that the tread sits on. The layers of rubber based
compounds, steel and polyester cords all joined to the sidewall which has its own
construction elements. It all comes together to form the carcass of the tyre.
Four-Wheel drive tyres rotate at different speeds and different pressures causing
significant friction and generating heat. This is a volatile environment and tyres
are under huge pressure it’s the strength of the carcass that keeps the
tyre firmly and squarely on the road and running balanced and true. So you
want the latest generation technology to protect you and your tyres from these forces. Underneath the tread and in the sidewall of Cooper four-wheel drive tyres are high tensile cords that’s 33% stronger than standard cords of the same weight. This means less risk of damage and a higher load carrying capacity. In the steel belts
under the tread you’ll also find “Super Tensile” that’s 15% stronger than more
commonly used high tensile steel. Adding a greater impact strength and better
puncture resistance. And because the materials are lighter, Cooper’s high
tensile construction reduces weight and rolling resistance to improve fuel economy. More adventurous off-roaders might
require extra protection. For them the “Armor-Tek3” carcass construction
is the answer. Cooper added a third layer of cord at a
unique 8 degree angle. This reduces damage and tear. It works like this this…
this material represents construction of a typical 2 or 3 ply tyre where all plies
run in the same direction. Take a sharp rock like this found on any
four-wheel drive track. Watch how easy it is to puncture and tear down through the
material. Now this material it’s better quality because it’s “rip stop”. Woven
across at regular intervals just like the plies in Armor-Tek3.
You can see it’s nearly impossible to puncture or tear. Armor-Tek3 also
improves steering response. Take a look at how Armor-Tek3 helps this
vehicle return more rapidly to centre steering. Compared to this vehicle fitted
with another common four-wheel drive brand. Right now let’s look at tyre compounds. The mix or recipe of ingredients that determines the tyre’s grip and wear characteristics. There’s a lot of technology and chemistry that goes into Cooper’s latest generation rubber compound. It’s like each tyre has its own
magic recipe and getting this formula right is something of an art.
Plastic comes from the same basic ingredient. We’ve all experienced that the quality
of plastic can differ dramatically. Some are cheap and brittle and break easily,
and some are more durable stronger and more flexible. They look the same but
they’re certainly not it’s the same with tyres. Cooper had been developing leading
compounds for over a century. Making tyres renowned for safety stability,
strength, and performance. Today, Cooper uses this amazing ingredient
called “silica”. Used properly coupled silica works like this… like a Cooper
tyre this ball has high content silica while this ball is just like most other
brands with low or no silica at all. Without silica the plain rubber ball has
high rebound. In the ball with high silica the rebound
is reduced. In a tyre that simply means more contact with the ground, less bounce, less friction, better grip, and more mileage. Now many other brands claim to
use silica but if it’s not chemically infused coupled silica mixed with other
materials in a certain way, these benefits just aren’t delivered. The magic
lies in how its added that’s what makes the greatest difference. Imagine baking a
cake with chocolate chips that don’t melt or blend in and become part of the
mixture. You’re going to end up with a lumpy cake, with occasional chocolate
taste. Compare that to a cake made with
chocolate chips all melted together. You get a uniform taste with every bite…”Mmmm”. In building tyres with all the benefits of silica this latest generation mixing process is known as “coupled silica”. Cooper uses up to four times more coupled
silica throughout the range, the extra grip combined with Cooper’s strength
means more miles without sacrificing grip. For wet weather breaking, or an
emergency lane change you’ll appreciate the extra grip of coupled silica. And remember – your tyres are the single most important safety feature on your vehicle. With Cooper tyres you get the latest technology in “Tread Design”, “Carcass Construction”, and “Compound Formula”. For strength, safety, stability, performance, and value for money. Tested and proven in Australia, With a mileage warranty of up to 80,000 K’s you get a tyre designed to go the distance. And that’s what makes Cooper, tyres worth owning.
