I also cannot see why regenerative braking alone is any different, in terms of tire wear, than caliper-on-rotor braking used for the same deceleration. There is something associated with regenerative breaking that I can see being a tire wear issue... one pedal driving.

In an ICE car, oscillating around the proper pedal position needed to maintain a particular speed leads to a cycle of coasting (not so hard on tires) and accelerating (harder on tires). With one pedal driving, at least with excessive oscillation, the cycle consists of regenerative breaking (harder on tires than coasting) and potentially more acceleration because the car slowed more rapidly. The more consistent you are at maintaining pedal position, the less the difference.

This might be best exhibited in downhill driving. An EV nudges the driver to be intentional about their downhill speed by applying regenerative braking, thereby requiring the driver to push the pedal down to reduce the braking. But on steep enough hills, there is still some braking. In an ICE vehicle, the driver might be more prone to just coast and let the car go a bit faster than they would have intentionally chosen.

It is generally trivial to maintain a steady speed with one pedal driving.

I think you're absolutely right, assuming the driver is paying attention. Too many don't. I encounter a lot of people bouncing around in a 10-15 mph range (sometimes 20-30 mph) on the highway while they are looking at their phone. This happens in all kinds of vehicles, but the coasting vs. regenerative braking impact on tires emerges in these situations.
