Depends what size you like to run.
A direct replacement is the Hankook RA10 is a 185C15
Not easy to find tho' - you have to do your research.
You can still find Firestone F560 in a 165x15; But you have to keep your ear to the ground. Firestone make batches of them from time to time and if you know you can grab a stock. Then when they are gone, you have to wait a couple of years for the next batch.
