C20 wheels/tires suggestions/thoughts?

[KevinK7]

I've got a '68 C20 that I plan on lowering (currently thinking 2.5/4) and wondering about wheels/tires.

What's out there in a diameter greater than 16" and less than 20" ?(along with readily available tires in whatever diameter)?

I believe the factory size wheels on the C20's ('68) was 16.5x6 8-lug.

I would like the wheels/tires to fit/fill the well with the lowering I have planned (2.5/4) and I'm thinking of black rims.
I like the look of the Detroit 8-lug Steelies, but I believe they are only available in 20", and I think I'd like more sidewall in the tire than I'd get going that route.
I also know there are steel F*rd rims 16x7 that would work.

SO, what's out there that in somewhere in the 17/18" range 8-lug wheel?

Pics would greatly be appreciated

Thanks,

Kevin

Here's the truck now (and I plan on keeping the patina look)
