Hi.
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

I believe the original rims are 16" x 4.5"

Correct. 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.

If you're smart enough to take it apart, you darn well better be smart enough to put it back together.

Kevin,

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.

If they have 6 hub cap clips, they're likely 4.5" wide. 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.

I got 3 clips and 6 clips mixed up in my mind. Yes. The earlier rims - 4.5" wide - have 6 clips. The later rims have 3 clips.

Just picked up a 16x4.5 with 3 clips to go along with my other 4.5’s with 6 clips. I added 3 more. Now the clips don’t match. Original 3 are fatter, but so…

37 GC If your truck is an art deco series, as opposed to an AD, it would have come with 4" wide wheels. Early AD wheels (47 and 48, I believe) also used 4" wide wheels. But the wider wheels should fit fine.

Yep, I was aware they should be 4”. 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?
