The Kendas wouldn't be original, so it matters not what the original tires were, since you can't buy them.
The Canadian-Market 1976 Bridgestone Submariner I bought at Goodwill on January 1 still had it's original front gumwall, "The Original High Pressure Tyre" or some such.
I rode the bike with it's badly decaying "tyres" for some weeks before replacing them one night after riding it home on a pinch-flatted rear tire. I was running 55psi on- and off-road for my 145lbs and neither tire blew (sigh).
