This is due to Formula 1 Technical Regulations on maximum brake size which is limited to a diameter of 10.9" or 278mm and to limit the cooling potential they limited the rim size. The thinking is that 13" rims (332mm max) would limit ability to cool the brakes because of the limited space. The high side wall is a consequence of the small rims.
FYI, F1 cars were braking 4.5G going into turn 10 at the German GP, so I guess that is limited.
