I have a '67 c20 that is stock height. I have a set of the H2's and I have read that the rims will work, but I need a useful recommendation on tire size.
I have done searches on this forum and Google 'til I'm blue-in-the-face but have not found anything definitive. I have trial fitted the H2 rims on the truck and have measured and plotted and figured, but cannot come up with an answer on tire size that would make me comfortable to pull the trigger on buying tires. If I have to use spacers.. so be it.

At present, I am feeling very stymied in my efforts.

Again, anybody run H2s on their stock height, 2 wheel drive C20?
If so, what tires are you using?

Which H2 rim? 17" or 20"
