Still in use on a few lines of the Paris Métro
This is one of the things I strongly associate with Paris: the slight smell of burned rubber when you enter a Métro station of a line with rubber tires.
Pro tip for Paris visitors with children: ride with one of the automated lines 1, 4 or 14, and enter through the very first door. There is a fake (printed) control panel for children below the front window [0].

I said “used to” because, from what I understood, the development of ABS made breaking characteristics of traditional trains much better than before, which reduces the improvement you get with tires.
(Don't quote me on that though, I got this from a coffee machine discussion with a former metro driver when I was working for RATP 10 years ago so my memory may not be 100% accurate at this point)
At least for tramways I know for sure[1] that the tram will happily have you break your arm inside the tram because it braked too strong in case of emergency rather than crushing a pedestrian that crossed in front without paying attention.
Maybe the rules are different for metros though, given that there aren't as many pedestrian on the way…
[1] because I got the information from the system design team of a big tramway manufacturer I worked with no later than last year so my memory is much fresher, and the source is more reliable.
It mentions Paris Metro line 14.
Ten of the lines are rubber-tired. Instead of traditional steel wheels, they use pneumatic traction, which is quieter and rides smoother in Mexico City's unstable soils. The system survived the 1985 Mexico City earthquake.
