Tires for 1974 Beetle

I cannot find tires for my 1974 Beetle - 165/R15. Apparently P165/75R15 and P175/70R/15 will work, but having trouble even finding them. Any other options for tire size, and where I might find them. I live in the Washington, DC area. Thanks. Ted

they are on a backorder though…

These guys have just about any size, not cheap:
