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).
Station: How far the baby is down in the pelvis. Measured in negative and positive numbers. -5 is a floating baby, 0 station is said to be engaged in the pelvis, and +5 is crowning. Uterus: Female reproductive organ that weighs about 2-3 ounces and is about the size of a small woman's fist prior to pregnancy. During pregnancy this organ becomes 10 by 14 inches and weighs in at about 2-3 pounds. This is where a normal pregnancy takes place.
