How Giti Tests EV Tires

Giti combines computer-based simulation, proving-ground testing and vehicle-manufacturer validation when developing tires for EV applications.

For the BMW iX1 and iX2 project, Giti designed the GitiSynergy H3 at its European R&D Centre in Hannover. Testing took place at Giti's MIRA proving ground in the United Kingdom, followed by additional validation in Germany and Spain.

Giti's AdvanZtech platform also includes rolling-resistance prediction, pattern-noise simulation, structural-noise simulation, energy-optimization simulation and durability-testing technologies. These tools help engineers assess efficiency, comfort, handling, load capability and wear before and during physical vehicle testing.

It starts with the vehicle, not just the tire

An OE tire program 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:

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 optimization, simulation and physical testing.

A simplified OE development journey looks like this:

BMW as a real-world example

For the BMW iX1/iX2 program, 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 optimizing one tire characteristic in isolation.
