Book 3 — Changing Wheels Equalizes Wear on Baby-Cab Tires
Reading edition
The front and rear wheels of a baby cab are usually of the same size and the tires on the rear wheels are worn much more rapidly than those on the front wheels. By changing the position of the wheels, the wear on the tires is equalized, making it unnecessary to renew them until all are worn out.—J. Cecil Alter, Cheyenne, Wyo.
