We tested the Hercules Raptis performance tire (205/55R16 stock size) on a 2002
Subaru WRX wagon for approximately 11,000 miles. They were
reasonably quiet and did not squeal during spirited handling. Rain performance

are showing the tread wear bars or are getting close, they are not
going to perform well in the rain, regardless of how good your tire was when new!
