空気圧はそのままとする事が殆どであった。However, in the case of conventional cars, the car must be stopped in order to adjust the tire air pressure, and adjusting the air pressure itself (especially the work of increasing it to a higher level than before) is necessary.
Because it was troublesome, even if driving conditions and road surface conditions changed,
In most cases, the air pressure was left unchanged.
