should i replace the tires/tubes to sell vintage bicycle? new to this site.  I have a vintage GT Pro Performer from my youth, all original and am considering selling it.  The tires are original but would fall apart if someone tried to ride it.  Is it worth replacing the tires/tubes with new ones to get more money when i go to sell it.  Trying to figure out if I should just leave it alone and let the next owner worry about it or if it would add value to the sell greater than the price of the tires?
thanks...
If it's really vintage (collectible) and has value for being vintage and the tires are original, don't change them.
When people buy vintage (collectible) thing, they want everything vintage, even if not immediately usable; if you change anything thing, it will loose value (as a collectible object)
The best thing would be for you to find good working order original tires.
