Tire Grip vs Rolling Resistance
Optimise tread compound and construction locally per tire zone and integrate vehicle torque control to balance grip with rolling resistance.

Business Context
Tires must generate sufficient traction for acceleration, braking, cornering, and stability across varied road and environmental conditions. Characteristics that increase mechanical grip can also increase tire deformation and energy losses, contributing to higher rolling resistance and greater vehicle energy consumption. Reducing rolling resistance improves fuel economy or electric range but can create concerns about braking, wet-road behavior, or dynamic performance if achieved through inappropriate reductions in traction capability.
Automotive TRIZ Resolution
Automotive TRIZ separates traction requirements according to location, operating condition, and tire behavior rather than treating grip and rolling resistance as one fixed material property. Tread compounds, internal tire construction, pressure management, tread geometry, and localized material characteristics can be optimized for different functions. Vehicle control systems can also manage torque and braking more precisely, reducing unnecessary tire slip while preserving available traction when demanded.
Applicable TRIZ Principles
Principle 3 – Local Quality assigns different material or geometric characteristics to tire regions according to their functions.
Principle 15 – Dynamics adapts tire-related operating conditions and vehicle control according to driving demand.
Principle 35 – Parameter Changes modifies material properties, pressure, deformation behavior, or tread characteristics to alter the relationship between grip and energy loss.
Expected Outcome
Maintained or improved tire traction
Lower rolling resistance
Reduced vehicle energy consumption
Better integration between tire and vehicle control behavior
Decision Indicators
Early indicators that this contradiction is limiting vehicle development include:
Lower rolling-resistance tires produce unacceptable traction losses.
Grip improvements significantly increase energy consumption.
One tire compound must satisfy substantially different local functions.
Tire deformation contributes disproportionately to vehicle energy losses.
Vehicle control systems frequently compensate for limitations in tire behavior.
Monitoring these indicators helps identify where traction and efficiency requirements can be differentiated rather than balanced through a single uniform tire characteristic.
