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.

- globular-toast 2y agoWhen 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/what-is-a-good-noise-rating-for-tyres-tyre-noise-ratings-chart-explained https://www.protyre.co.uk/car-help-advice/tyre-selection/wha...

- nayuki 2y ago> 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.
