Quick google says regenerative breaking has ~65% efficiency at energy recovery, but that includes the 10-20% lost when converting stored energy back into kinetic energy. So it sounds like regenerative breaking would covert ~75%-85% of kinetic energy into stored chemical energy. I'd expect to see similar reduction in tire and brake wear as well, maybe even more it probably depends on how break dust is generated, if it has a curve where more is generated with greater breaking force applied, by dropping the force on a break pad to 15% of it's previous value we might see an even greater reduction. This is all speculation though, I am not a physicist.
