New owner 1967 C10 swb fleet

[TDH1989]

Hey guys just wanted to join the site now that I've got a 67 c10. I've had the truck for roughly a year and been working on it to get it up and going. Had a couple of questions as far as what size tires I could fit under it. It's bone stock as far as suspension but I was hoping to fit 20 in. rims with a tire that has pretty good side wall to it. Thanks for any suggestions or help y'all can give. Pics would be awesome also. The names Ty. Also if some can tell me how to post pics I'll do so.
