Why are there reflective lines on the side of tires?

Reflective lines are clearly visible when illuminated by a car headlight. The material is retroreflective, i.e. it reflects in the direction of the radiation source. The two tire sized circles of light make a cyclist easily seen and recognized.

In many countries, a reflective strip is allowed as an adequate replacement for wheel reflectors. Other reflectors are only permitted when they form a similar circle of light like the reflecting rings on the tire.

Because of this considerable safety advantage, we began to use reflective lines years ago as standard for all high-quality touring and city tires.!Reflective Strips on Tires
