OT? bicycle tires

1) I thought, starrting about 1978, that bicycle tires had to have a
reflective strip on each side, so the tires would show up in
headlights. I've seen tires for sale without that. ???

I don't think it was the tires that needed a reflector, I think the
rule required that the "wheel" have a reflector. Mine have them
attached to the spokes.
