some relatively easy CMP 15-cwt questions for you...

Bonjour Von Cougar

Tire size was fairly simple...... on the CMP I believe that only two sizes of wheels existed..... the 16 inch rims.... usually with 900X16 tires... some of the smaller 15 cwt truck carrying a heavy load... such as radio trucks had 10:50 X 16 tires.

The larger 30 and 60 cwt trcuks had 20 inch wheels...again usually 900 X 20 tires... special applications had 10:50 X 20 tires.

In both cases the wheel rim is made of two pieces bolted together approx. 3/16 inch thick... I beleive that most wheels were made by Keyes....which still exists today.... they were stamped using a 1500 ton press..... some nut cracker....
