EV Performance Tyre Requirements (Critical)

BMW i4 M50 places extreme demand on tyres due to performance and weight.

Key Factors

Instant Torque (AWD EV)

• Very high acceleration forces

• Increased tyre wear

• Requires strong grip compound

High Vehicle Weight

• Battery significantly increases load

• Requires correct load index rating

Noise & Comfort

• EV cabins are quiet

• Tyre noise becomes more noticeable

• Prefer tyres with acoustic foam technology

Staggered Setup Explained

BMW i4 M50 uses a rear-biased staggered setup.

Benefits

• Improved traction under acceleration
