Background: SYNOPSIS: Goodyear tyres have joined the space programme with the announcement that Apollo 14 heads for the moon in January. It will carry the first year to be used on the moon. They have been specially designed for the space Administration and are ordinary looking black rubber tyres, 16 inches high, four and a half pounds in weight, and are self inflating. Walt Curtis, research designer, talked of it's history.
There were other designs prior to the latest which changed as theories of the moon changed. One resembled an open chain link fence covered with more closely woven wire. Another was fitted with discs that looked like pads.
The lunar tyres will be fitted on aluminium wheels which have been tested for endurance and for extreme cold. It is though that they will have to withstand a temperature of minus 60 degrees.
They are inflated in a vacuum chamber to a pressure of one and a half pounds per square inch, travel in a state of collapse under normal atmospheric pressure, and inflate in Space.
The tyres will be fitted ton a rickshaw type vehicle called the modular equipment transporter. It will be pulled by the astronauts and will carry the 120 pounds of equipment and rock samples. It is designed for trips up to two miles from the landing site.
