Connaissances Essentielles sur les VE

How Does Giti Develop Tires With Vehicle Manufacturers?

Giti works with vehicle manufacturers through an Original Equipment development process in which tire design is engineered around the requirements of a specific vehicle. Giti combines materials engineering, tire design, simulation, prototype development, proving-ground testing and vehicle validation through its globally integrated AdvanZtech R&D platform. 

It starts with the vehicle, not just the tire

An OE tire programme is different from simply supplying an existing tire in the correct size.

Vehicle manufacturers establish performance requirements based on characteristics such as vehicle weight, powertrain, suspension, handling targets, efficiency, noise and intended driving characteristics.

For an EV, engineers may need to address competing requirements such as:

Battery weight → greater tire load requirements
Instant torque → increased demand on traction and wear
Driving range → low rolling resistance
Quiet powertrain → greater sensitivity to tire and road noise
Vehicle dynamics → grip, braking and handling requirements

Giti's engineering process

Giti's AdvanZtech platform integrates R&D expertise across its international engineering network. Its development capabilities include compound engineering, tire structure optimisation, simulation and physical testing. 

A simplified OE development journey can therefore be presented as:

Vehicle Requirements Tire Concept & Engineering → Compound + Structure Development  → Digital Simulation → Prototype Tires → Laboratory & Proving-Ground Testing  → Vehicle Testing & Optimisation → OEM Validation / Homologation → Original Equipment Production

BMW as a real-world example

For the BMW iX1/iX2 programme, BMW required very low rolling resistance without compromising handling performance.

Giti engineered the GitiSynergy H3 to meet those requirements, followed by testing and validation across multiple European facilities before achieving BMW homologation. 

Key takeaway:

OE tire development is a vehicle-specific engineering process. Giti works with automakers to balance efficiency, safety, handling, comfort and durability rather than optimising one tire characteristic in isolation.
