Factory tire size

[One Chevy Scotty]

In 1972, on the C20 trucks 4x4, what was the tire size that it came with? and if anyone knows the tire manufacturer/models that would be great help too...the truck that I purchased has 35's and I want a more sedate original look. I am pretty sure that I don't really want the 16.5 rims, but rather am thinking of some 16x7.5 plain steel wheels painted white...what do you think?

If you're interested in original tire size, stick with the 16.5's... That's what it came with. I believe the tire size was somewhere around 33 x 12.50 16.50 on the 4 x 4's. The 2WD came with 9.50 x 16.5 up front.

I have 35's now and they look too big...I thought that they came with like 285 or 265 size tires...still searching the net for the right size...I keep coming up empty....thanks for the insight.

There was more that one stock size.... mine came with 7.50-16s, which were tube-type tires on lock-ring wheels. Depending on brand, the tires ran 31" to 32" diameter. 235/85-16 is fairly close to 7.50-16.

There were no stock 33/12.50s, and I'm not aware of any OEM 35" tires offered to the public.
