Why is tyre noise more noticeable in an electric vehicle?

Tyre noise can be more noticeable in an EV because there is less engine and exhaust noise to mask sounds generated by the tyres, road surface and airflow.

EV tyre development therefore considers tread-pattern noise, structural vibration and the transmission of sound into the cabin. Giti’s noise-control technologies include:

• Pattern Noise Dislocation Technology 
• PDT 4.0 Pattern Noise Simulation Technology 
• Vibration-Reduction Structure Design 
• Structural Noise Simulation Technology 
• SilentCavity Technology 
• GitiSilent Technology 

For the BMW iX1 and iX2, the GitiSynergy H3 was specifically engineered to deliver reduced noise alongside low rolling resistance and extended wear life. Giti AdvanZtech noise-control technologies, BMW OE engineering details
