Most alphanumeric tires feature a load range of B, which indicates that they are restricted to the load that can be carried at a maximum inflation pressure of 32 psi. C, D, or E tires are capable of greater loads. Most load range C, D, and E tires are intended for light-truck applications.
By Maria Pyanov in Birth. âYouâre really small. âYour baby bump is huge! Looks like a big baby is on the way. If youâre on the petite side, or if youâre expecting a larger baby or if youâre a first time mother-to-be, you might hear a great deal about babies being too big to fit through the pelvis or birth canal. When a baby cannot fit through the pelvis, this is called cephalopelvic disproportion (or CPD for short).
The difference between the male and female pelvis The pelvis is a bony ring, interposed between the moveable vertebrae of the vertebral column which it supports, and the lower limbs upon which it rests.he size of the lesser pelvis is particularly important in obstetrics because it is the bony pelvic canal through which the fetus passes during vaginal birth. To determine the capacity of the female pelvis for childbearing, the diameters of the lesser pelvis are noted radiologically or during a pelvic examination.
