The large tires with air give the child a ride that is smoother and more comfortable, plus they make the parent’s job of pushing much easier on all surface areas. Just like with other transportation objects, such as hand trucks, these strollers can glide over problem areas easier than ordinary strollers with just rubber or plastic wheels. The air in the tires give the stroller the buoyancy it needs to move smoothly over branch debris, rocks, pebbles, sand, dirt, and grassy areas easily.
