Aspencade 1984 ,what size and what brand?

hi all
i heard about this size for my bike
165/80R15 but they are rare here around my location,
do i have other options of size and what brand should i looked for?

and what about by front tire,my Dunlop D404 Front is almost done,


thanks for your advise,
Gervais

The Bridgestone Battleax BT45 is a great front tire, it is compounded hard in the middle for good long life and soft on the sides for the curves. I got 27,000+ out of my last one.
