A tire's section width (also called 'cross section width') is the measurement of the tire's width from its inner sidewall to its outer sidewall (excluding any protective ribs, decorations or raised letters) at the widest point. This measurement is made without any load placed upon the tire and after the tire has been properly mounted on its industry assigned measuring rim and has been inflated and reset to its test pressure after 24 hours.
Overall Diameter
A tire's overall diameter is the outer diameter of the tire measured in the center of the tread. This measurement is made without any load placed upon the tire and after the tire has been properly mounted on its industry assigned measuring rim and has been inflated and reset to its test pressure after 24 hours.

Also;
Tire Circumference Differences; "...
ensure that the tires you decide on buying are not discontinued (not now manufactured by the tire maker). Ask around - don't rely on verbals by just one dealer. Because; A tire slasher messed my plans up $ wise in JAN when he slashed two 32x11.50 Daytons; they were just a year old at the time. I found that Dayton stopped making em (in 32s) right after I bought them and None are avail anywhere....; so I ended up w/ two Michelin LTX® M/S 32x11.50R15 in an emergency buy that late Saturday afternoon; guess what? right, they stopped mfg em too! Prob is finding tires in the future to replace the Daytons that have an actual inflated diameter close enuf (see below) to whatever is in in-place so that we can do the std rotation & don't rip up the Xfer case, etc. This is by BW for its Xfer cases, esp the 1356; Diameter & Pressure Difference for Transfer Case Operation; "...Before attempting any diagnostic work or trouble shooting on the transfer cases, make sure that the tire pressures and circumference are all the same. Do not just compare tire sidewall labels, you must measure each tire around the center of the tread. A stagger gauge will let you do this with the vehicle on the ground in 5 minutes. The tires must match in size to ¼” (.250) if they do not sell the customer on a new set of tires and again measure them again..."
