A beach cart kit and method for transporting cargo over soft-sand may include a handle and a telescoping support member coupled to the handle. The telescoping support member allows the handle to move between several positions. A cargo deck may be coupled to the telescoping support member via a hinge. The hinge permits the telescoping support member with the handle to fold towards the cargo deck when an assembled beach cart is placed in a storage state. An axle may be coupled to the cargo deck for supporting two wheels. Each wheel is removable from the axle when the assembled beach cart is placed in the storage state. Each tire is inflated within a predetermined pressure range such that each tire rotates properly over soft-sand environments when supporting the cargo deck along with any cargo. The kit includes a tire inflation tool providing a predetermined circumference for each inflatable tire.
