In page Transport in Antarctica:

"

A normal car on tires has very limited capability in Antarctic conditions. Scientific bases are often built on snow-free areas (oases) close to the ocean. Around these stations and on a hard packed snow or ice, tire based vehicles can drive but on deeper and softer snow, a normal tire-based vehicle cannot travel. Due to these limitations, vehicles on belts have been the preferred option in Antarctica. In 1997, two specialized cars with very large tires running tire pressure as low as 1.5 psi (0.10 bar) travelled onto the high Antarctica Plateau, giving strong indication that tire based vehicles could be an option for efficient travelling in Antarctica.[1][citation needed]
