When you build a house you make sure the foundations are strong and suitable for the construction that is going on top.
It’s the same with tyres. You need a strong foundation for the construction that goes on top.
You might be surprised to learn that while tread design is critical, it’s the carcass construction that accounts for up to 70% of a tyres performance.
It’s the strength of the carcass (what you can’t see under the tread) that keeps the tyre firmly and squarely on the road and running balanced and true.
Cooper has developed three different carcass constructions to match your specific requirements; R-Tech Engineering, High-Tensile Construction and Armor-Tek3 Technology.
So let’s take a closer look at the carcass constructions that represent the latest generation in tyre technology.
Today’s SUVs have a higher centre of gravity, allowing you to have a better view of the road. Cooper Tires has specially developed R-Tech (Response Technology) to meet the requirements of today's high riding SUVs.
R-Tech Engineering works in 2 ways:
|Extended Bead Filler
The bead filler which runs along the inside of the tyre is extended to further reinforce the sidewall and strengthen the carcass construction. This improves lateral stability for safer handling, enabling a faster steering response and more control in emergency maneuvers such as sudden lane changes.
|Variable Density Nylon
A nylon overlay of varying thickness, wraps around the steel belt of the tyre. This nylon overlay works to offset the stiffness of the bead filler. This means you will get a smoother, safer, more comfortable ride.
4WD tyres rotate at different speeds and different pressures causing significant friction, generating heat. This is a volatile environment and tyres are under huge pressure, not to mention the challenge of the terrain. Why wouldn’t you choose tyres that are built to withstand extreme situations?
Depending on how adventurous you are, Cooper has developed 2 kinds of carcass constructions to meet the needs of your off-road adventures:
High-Tensile Construction is made up of 2 main components:
Underneath the tread and in the sidewall of Cooper 4WD tyres are High-Tensile cords (or plies). This gives you 33% more strength than standard tensile cords. 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 steel belts. This gives you 15% more strength than commonly used high-tensile steel belts, adding greater impact strength and better puncture resistance.
Armor-Tek3 works in 2 ways:

Not only does High-Tensile Construction provide maximum strength and protection, you also benefit from improved fuel economy thanks to the reduced weight and rolling resistance from the construction. While with Armor-Tek3 you are covered with extra protection off-road for peace of mind.
