Toyo Tires’ new e-balance technology for commercial truck tyres improves fundamental performance characteristics and their compatibility with one another. These characteristics are tyre life, irregular wear resistance, endurance and fuel consumption. All of these improvements help to lower fleet operating costs and make e-balance tyres more environmentally friendly.
The new technologies of e-balance incorporate improvements in the areas of Tread Profile Retention, Bead Profile Retention, and overall Simulation for optimum tyre design.
Tread Profile Retention
Tyres that utilise e-balance exhibit improved tread profile retention, meaning less service growth compared to conventional tyres. The flatter tread radius provides an optimised footprint shape resulting in even wear, less irregular wear and longer life. Strain at the belt edge is reduced by approximately 30%, which also helps to improve tread profile retention.
Simulation of Vehicle Behavior
Blue Truck: e-balance
Red Truck: without e-balance
e-balance tyre has better handling performance than the tyre without e-balance.
V: 40km/h Steering Angle 90°
Bead Profile Retention
Tyres that utilise e-balance have higher bead stiffness to achieve improvements in bead profile retention. This leads to a reduction in irregular wear and an improvement in endurance. The bead area profile is retained even after service. Increased bead stiffness is achieved through the use of a high stiffness bead core, which is then surrounded by high stiffness rubber. A low heat build-up rubber is also used in the bead filler area. Strain at the ply turn-up edge is reduced by approximately 20% over conventional tyres.
There are four simulation technologies utilised in e-balance. Tyre irregular wear, tyre profile change, tread pattern noise and vehicle handling behavior. All of these areas are analysed with careful consideration to how they affect one another. This new simulation technology allows for optimisation of tyre design with much higher accuracy than what was possible before.
