About Zero people use riser pads in modern skateboarding. Nobody cares about wheel-biting either, even with loose trucks. if you wheel-bite and fall, you failed to land your trick. The goal is to land 'bolts', as kids say. (Source - any skate video)

I skate risers with tight trucks. As parent suggested, it helps with stairs and drops.
