An engineer, of suitable background, will tell you the "grip" of
the tire is doing the trick.

Friction is one of those subjects that people discover, in fits and
starts every once in a while, to be yet still more complicated (and
interesting) at the micro/nano scale than they thought as of the last
go-round. I don't have access to hardcopy or online journals at the
moment, but if memory serves, Nature has run some interesting articles
over the last couple of years.

I don't know that this falls in the "friction" dept. but the stuff
they've been finding out about gecko feet is pretty interesting.
