Tirerack is showing the Bridgestone Potenza RE92 in 175/65R14 in closeout (Fewer than 2 tires available) since some time, so if they are still being made, then Tirerack si not showing it because when you try to order the "Fewer than 2 tires" a warning pops up saying: "The specially-priced closeout items you are buying are first quality products covered by applicable manufacturers' limited warranties. They are, however, available only until our current inventory is depleted."

Tire rack usually has them.
