the.com/tyre

The only part of your car actually on speaking terms with the road.

means A rubber ring fitted around a wheel's rim to cushion the ride and grip the ground.

from From 'tire,' originally meaning the iron rim or hoop fitted around a wooden cart wheel — likely a shortening of 'attire,' since the metal band was the wheel's 'dress' or covering. British English kept the 'y' spelling, 'tyre,' once rubber pneumatic versions took over in the 1800s, while American English stuck with 'tire.'
