Armour EV4 — a tyre designed for front loaders and heavy trucks operated 24/7. It's a reliable power element of the chassis, providing stability of special equipment's working characteristics over a long period.
Strength Architecture
At its core is a high-load carcass containing 20 layers. This cord density allows withstanding peak overloads and provides a colossal margin of strength during dynamic impacts against rocks. Reinforcement in the breaker zone minimizes the growth of radial cracks and guarantees the stability of the contact patch shape even at increased pressure.
Harmony of Traction and Self-Cleaning
The tread pattern geometry is a key factor in performance. The design features asymmetrical blocks with variable pitch. This pursues three goals:
- grip on loose soils;
- stability on hard surfaces – the "broken" edge of the blocks increases the contact area during turns, reducing the risk of lateral drift;
- self-cleaning – the structure promotes the ejection of viscous mud and small gravel from the grooves, preventing "clogging".
Fighting Overheating
Here, the rubber compound recipe has been revised – the high content of heat-resistant polymers has reduced internal heat generation by 12% compared to analogues. This extends the tyre life and maintains the elasticity of the tread up to 60% wear.
Key Features of Armour EV4:
- an ultra-strong 20-layer carcass provides load capacity and puncture resistance;
- universal kinematics for gravel, sand, and rocky terrain – active self-cleaning of grooves from abrasives;
- an enhanced bead ring design prevents the tyre from coming off the rim during sharp maneuvers;
- minimization of the risk of tread separation during prolonged summer operation due to thermally stable additives;
- the tread pattern allows for deep cutting.
