I have a 1951 3100. I have 16" x 6.5" bias tires on it.
The rims are 6 lug.
I do not have a spare.
I have a few junkyards around me. If I wanted to pickup a rim for a spare, what size would I be looking for?
Thanks,
JD

Later 16" rims (55.2 and up) were 5" wide. They usually had only 3 hub cap clips instead of 6. The 5" wide wheels were used with 6.50-16 tires. If 6.00-16 tires came on the truck, it would still have had 4.5" wide rims. The 4.5" wide rims were phased out (along with 6.00-16 tires) for '56 model trucks. Later Vehicle Info Kits dropped wheel size data for some reason. But they do not include 6.00-16 tires on any models.

I am not sure if the rims are original to my 51. My rims have 6 hub cap clips.
I have 16" x 6.5" tires on it, so that would mean the rims are 16"x5" correct?
Thank you.

I'm pretty sure your current 6.50-16 tires weren't installed at the factory. The will fit on the narrower 4.5" rims. That's what I have on my 3100.
When GM went to the 5" wide rims (a better fit for wider tires) they reduced the number of hub cap clips to 3, but there may be 6 clip holes, and possibly someone installed more hub cap clips, but I doubt someone went to that much trouble.

Yes. The earlier rims - 4.5" wide - have 6 clips. The later rims have 3 clips.

Early AD wheels (47 and 48, I believe) also used 4" wide wheels. But the wider wheels should fit fine.

When I brought the truck home it had one 4”, two 4.5, and one 5”. I’m using 6.50 16’s on 4.5’s and they look pretty good. I’ll use the 4” for a spare, it’s not in great shape. All are 4 slot. When were the 8 slot wheels used?
