Hey all,
Just picked up a vintage 70s Raleigh Sport. It looks like it has very old, if not its original, 26 inch tires tires. As a part of my overall restoration plan, I'm looking to replace these with something new (safer). I want something that goes well with the vintage look and I'm digging gumwall tires. I'm not too familiar with tire brands. Can anybody recommend a 26 inch gumwall tire model? Or feel free to recommend any other type of tire that you think looks good on these vintage bikes.

Also, if I wanted to, would it be possible to switch to 700c tires on these old bikes? I'm guessing it would entail replacing the whole real internal 3-speed hub, but it hasn't been working well and if I can't get it fixed I was planning on installing a modern (new) internal 3-speed hub anyway.

I'm new to bikes and pardon me if these questions don't make any sense mechanically.
