What are the best winter tires for a rear-wheel-drive JDM car?

A dedicated studless ice-and-snow tire beats any all-season on a RWD JDM car, where traction is already the weak point in the cold. Look for a severe-snow (three-peak mountain snowflake) rating and a soft winter compound that stays pliable below 45 degrees. Mounting them on a cheap second set of wheels is smarter than swapping tires on and off your summer wheels twice every year.
