What function does a pneumatic tyre’s flexibility serve when rolling over small surface irregularities?

Correct answer

It helps absorb shocks and improve comfort.

It helps absorb shocks and improve comfort alongside the suspension. A tyre also supports load and transmits braking, traction and steering forces. Behaviour depends on design, pressure, load, speed and road surface; there is no universal percentage of irregularities absorbed that can be assigned to every tyre. Maintain the manufacturer’s recommended pressure.
