Tire Information for the M37
and Similar Military and Civilian Power Wagons
Note: The following information is copied from the 1979 Tire and Rim Association Yearbook and from a 1949 Budd Company Catalog. This information is being provided as a service to fellow owners of this vehicle, but no guarantee is made to its accuracy either by the author of this page or of the source material from which it was created.
This page has been created to provide a summary of tire nomenclature, size, load, and fitment information for tires that may be mounted to the stock Budd GY-LTS rims found on the M37 and similar military and civilian Power Wagons. I have several pages on this website that discuss different types of tires that can be fitted to the stock rims. These pages have discussions on tire selection, purchase information, use of tubes and flaps, and mounting and can be accessed from the tire discussion page. There is a similar page to this on that has basic rim information.

The tires fitted to the M37 and similar military and civilian Power Wagons are 900x16LT or 900r16LT (LT standing for Light Truck). As can be seen from the chart below, the tires are mounted on a 6.50H 5° degree semi-drop drop center rim. More information concerning the rims used on these trucks can be found on the rim info page.
Using the information in the above two charts and looking at the general data chart below, one can learn various general facts about the design of the tires used on these trucks such as the width, diameter, and tube designation.
The following chart has basic load information for various tire air pressures and vehicle speeds for bias ply tires. Always consult the tire manufacturer's specific information for the tire you have fitted for confirmation of these values.
The following chart has basic load information for various tire air pressures and vehicle speeds for radial ply tires. Always consult the tire manufacturer's specific information for the tire you have fitted for confirmation of these values.
