System for evaluating the condition of a tire

A system for evaluating a tire condition, the system comprising:

• a housing;
• a tire-wear detector, which detects a tire-wear condition;
• a tire-presence detector, which detects a presence of a tire on the housing;
• and
• an electronic activator, which activates the tire-wear detector when the tire-presence detector detects the presence of the tire on the housing,
• wherein the tire-wear detector, upon activation, detects the tire-wear condition of the tire when the tire passes over the housing while the housing is placed on a ground surface,
• wherein the tire-presence detector detects the presence of the tire on the housing by detecting vibrations caused by contact of the tire on the housing, and
• wherein the tire-wear detector is deactivated in accordance with a falling edge of a signal from the tire-wear detector.
