My '78 CB750F came with a tubeless Dunlop K187 Mk II on the rear and a tubeless Dunlop Gold Seal F11 on the front. I don't remember what kind of mileage I got out of them, but in those days, if you wanted good performance and longevity, you'd install a Continental K112 on the rear and a Continental RB2 on the front. That's what the R100RT's came with and lots of touring riders soon adopted them. They too were tubeless bias-ply tires and worked fine on the '78 Comstar rims (though your '76 had spokes and required tubes).
