I've got a thread going over on the 1948 - 1960 page about a conversation I had today with the owner of American Wheel Specialst, LLC. in Pasco, WA. This company can supply new tubeless 19.5" wheels that use our big truck 5 lug x 8" circle bolt pattern. They can also supply reconditioned 20" lock ring wheels for guys that want to retain a stock configuration. So go over and check it out. Stu

 

truckdog, are you sure center hole on m-h is 8 inch? my 42-450 only has 6 inch. these rears are(i believe) heavier than f-3. i just wonder why lighter truck has bigger axles? pete

 

The bolt pattern on just about all the old Ford big trucks of the late 30s through early 50s was 5 lug on an 8" circle. That figure is determined by placing a tape on the outside edge of one lug and measuring across the wheel, past the second/nearest lug, to the middle of the third lug. That measurement will be 8" on your truck. The really early trucks, back into the mid or early 30s, had 5 lug on a 6 7/8" circle. That bolt pattern was used extensively on WW2 military vehicles and post war Dodges Power Wagons.

The center bore/hole of our wheels is 5 7/8". That closely matches your 6" measure. Stu

 

stu, you are absolutely right, i was thinking of center hole dimension. never too old to learn and listen!!! now i'm going outside and hit my head on something really solid! pete

 

Don't hurt yourself. It's not worth it. Stu
