Tires are primarily absorbers of visible light. Most passenger-car tires are black because they contain carbon black and dark polymers that absorb most visible wavelengths and convert the energy to heat. They are essentially opaque, so they transmit virtually no visible light.
They do reflect some light, but mostly as diffuse (non‑mirror) reflection from the rough rubber surface — typically a small fraction of incident light (a few percent to maybe ~10% depending on tire color, compound and surface condition). Wet or polished tires can show more specular (mirror‑like) reflection. In the infrared, tires also have high emissivity, so they absorb and emit thermal radiation effectively.
Short answer: mostly absorb, a little diffuse reflectance, and negligible transmission.
