This has come up before and I have saved the data thanks to the original
contributor John Edwards, as below:

1) for single vehicles
    - yellow circular sign with black numerals
    - sign is painted or attached to front or side of vehicle below drivers
line of vision
    - signs on front of vehicle are 9" in diam, side mounted plates are 6"
in diam
2) for combo vehicles (semi-trailer)
    - any tow or trailer that operate as one complete unit or rig
    - the front plate must have a RED "C" above the bridge class number
    - side mounted plates on a combo show separate bridge class numbers on
6" sign

To assist all concerned there is an expedient formula to use.

W = (A*P*N)/2000 where

W = gross weight of vehicle
A = average tire contact area in square inches (tires on hard surface)
P = tire pressure in PSI
N = number of tires

then round the number up to nearest whole number.
