When you buy tyres they actually come with a dB rating, at least in the EU. See: https://www.protyre.co.uk/car-help-advice/tyre-selection/wha...

Tires for my car range from 67 to 72db, which isn’t much of a range

> Personally I think we need to put cars underground
Nope, unless drivers foot the bill entirely. Tunnels are horrendously expensive to build and maintain. Projects like Boston's Big Dig cost billions of dollars, went over budget, and move a smaller number of people than a proper subway train system.
> without tunnels we'll be in traffic hell forever
Also nope. Adding more lanes just induces more traffic demand. We will never solve traffic by building more car infrastructure. We can only solve traffic indirectly - by mixing residential and commercial building, by making streets safe to walk and bike, and by building a world-class mass-transit system.
Could you expand on this? Above 20-30mph tire noise is the dominant noise from vehicles [1] and I haven't yet found a reference that shows significant reduction by choice of tires
Personally I think we need to put cars underground - without tunnels we'll be in traffic hell forever[2]. And imagine the quiet.
