Episode notes
EVs Reverse Old Tyre Assumptions
- EVs can accelerate faster than they can brake, creating new stresses on tyres.
- This reverses historical assumptions and forces tyre designers to rethink traction, wear and structure.
Tyres Consume A Large Share Of EV Energy
- Around 25% of an EV's battery energy is used just to overcome tyre rolling resistance.
- Reducing rolling resistance offers a large, direct opportunity to improve EV range and efficiency.
New Compounds Cut The Grip/Heat Need
- Modern compounds produce grip without needing heat, unlike older tyre technology.
- Hankook developed 15 patents for compounds to cut the historic grip-versus-efficiency trade-off.
