Has anyone out there read the latest CR? They have a pretty decent article comparing tires and the ones they list as their overall choice are the Goodyear Assurance TripleTreds. I know many Prius owners out there prefer the ComforTreds (#13 on the CR list). What is the difference between the two, other than price? I plan on replacing my OEM's with one of the two in the future, and I'd like to get opinions from those who have experience with them...thanks!
