I am debating to put on studs or not to. We average about 16ft of annual snowfall here. Many many steep roads. The town ranges from sea level to about 600ft above sea level. The studs help with traction on steep hills? I will be driving my 2005 WRX. This will be my first full winter here. Many cars here have studs, but many are FWD. Think it will be overkill with snow tires on the WRX?
