Tesla Model 3 - Finally.

[flyingcheesehead]

Several years ago I was doing some work in a Michelin warehouse when I noticed a batch of lower profile tires coming down the line that had about 1 - 1.5" of foam - like the packing foam in a camera or gun case - stuck along the tread part of the inside of the tire. I asked what that was all about and they said it was extra noise deadening for electric vehicles.

Yes! My factory tires were the Continental ProContact RX "ContiSilent" made specifically for Tesla. The "ContiSilent" refers to having the foam inside. Each brand has a different name for it.

FWIW, these Goodyears are even quieter, but AFAIK they don't have the foam. I think maybe they designed the treads to somehow be lower noise?
