Most city driving is below 22mph, so this is a useless bit of info. Living next to a stop sign in San Francisco, 100% of the traffic near my place is at speeds less than 22mph and I can assure you that the tire noise is completely inconsequential compared to the revving engines and obnoxious exhausts.
Living in Boise's Downtown, I live next five lanes of traffic drive 35 or 40 mph on an asphalt road fortunately not chip sealed, like many of Idaho's roads. The revving engines are bad, but tire noise is easily 50 dB 15 meters off the street.
And I can assure you that most of the car noise where I live is tire noise (typical speeds around or exceeding 40 km/h which is the default limit in urban areas around here) Especially when the streets are wet and/or when it's studded tire season (that is to say, about five months per year). I realize that both of those conditions are almost completely alien to Californians, but there is a whole world outside the Sunny State as well!
Same. My street is (steeply) uphill, so it's a mixture of exhaust smoke, huge revving, burnt rubber, tire skidding, burnt clutch... A veritable bouquet, at 8h30 in the morning.
All at <35km/h. Can't open my windows before ~10am.
