REDUCING ELECTRIC VEHICLE NOISE CAN BE ACHIEVED THROUGH UPGRADES TO MORE QUIET WHEELS, AND ADDING NOISE-DAMPENING INSULATION BEHIND THE INNER FENDERS
Soundproofing fenders and chassis is costly and does not reduce the source of the noise.
The greatest effect is achieved by using tires that emit as little noise as possible on coarse asphalt. Summer tires with a soft tire casing and medium-hard summer rubber provide the lowest measurement results on a Tesla Model Y. Not the EU value that is measured outside the car on the roadside.
Some winter tires also have their advantages with softer rubber that in itself dampens road noise. However, some winter tires emit a lot of noise if the tire tread pattern has a small degree of longitudinal tire tread. We have some winter tires that can actually be recommended as all-season tires.
Here are some good tips:
SPECIALIZED ELECTRIC VEHICLE TIRES WITH FOAM INSERTS REDUCE THE RUMBLING NOISE MEASURED INSIDE THE CAR
We measure the internal noise in the car with a noise meter at 70, 75, or 80 km/h, depending on the car model we measure, thus eliminating other noise sources. The potential for improvement is 1 - 5 dB, depending on which tire one is coming from. The so far measurably quietest Winrun R330 W-Silent can give a 5 dB gain compared to a hard sports tire, (marked SPORT on this website), in addition to better longevity (Treadwear 420 versus sports tires at 240), and significantly less tracking. Hankook has also made a good original tire for Model Y, but Winrun still measures slightly better on both noise and lifespan. Tracking is also slightly less on Model Y.
It is likely that the measurements we have done on Tesla Model Y are transferable to other electric vehicles with a similar weight and wheel size.

HERE WE MEASURE THE NOISE LEVEL ON MEDIUM ROUGH ASPHALT, INSIDE A TESLA MODEL Y
The EU value for noise is measured externally from the roadside on fine laboratory asphalt and provides misleading information.
