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).
As the cervix effaces and thins out, it also begins to stretch and open. This is called dilation. This widening and opening makes it easier for the babyâs head and the rest of its body to pass through from the uterus into the vaginal canal for delivery. The degree of dilation is measured in centimeters.
