obsolete 1939 B Rim Clamp

The first 6000 or so 1938 B rear rims were 24" 3 piece split rims with special 3/4 bolt clamps cast to fit them.

In later 38 and into the most all of 1939 production one piece 24" rims were mounted using the 2 footed clamps pictured. Still using 3/4 plain and excentric bolts. Anyone know what tire size was used on both of these obsolete rather narrow rims back then ?.

I have one somewhere with the original size tire. I am not sure the weather has not removed the size from the side wall. The rain has it so slimy where it might be that my electric wheelchair will not get to the area until it dries up or freezes. I moved getting stuff out of the way to put an addition on my shed. The rim was about gone.

Dick L I'm so happy you posted a reply. This photo of the second style B rim used showing one of the four small angles riveted to the bottom of the bead flange says a picture is worth a thousand words . The two footed special clamps fit behind the tab with a foot on both sides to keep them in place when tight. Do you have any of the special clamps that used 3/4 bolts ? I have extras if you want a set. For Free of coarse. By the width of the drop center you can see how narrow these old rims were. Less than 7 Inches.

I ran across a old thread where you doubt Split Rims were ever used on a B. I wish you could have been here when Gary Arneson and I Restored his B #751 with its split rims back like it was when new. ME LIKE A DUMMY TOOK NO PICTURES to show you. The special clamps used with the split rims had AM casting numbers. I will be seeing Gary soon to see if he has any pictures. He sold B 751. It may still be here somewhere in Texas.

Good to hear you are still here with us . God Bless

Thanks Paul Maybe we can one day convince Dick L that early 1938 Bs had split rims.

In those days the tire width was defined by the rim width, not the maximum width of the tire. The tire dimensions specified on the tire changed in the next 10 or 15 years to be the maximum width of the tire, wider than the rim width. Today farm tire catalogs available from most tire makers list the preferred rim width for a given tire width. With an 8" rim the tire might be as wide as 10 inches. You have to watch for fender clearance inside the rim for wide tires or add spacers to move the rim further from the fender so the tire clears.
