So far, I am very pleased with these tires. They are comfortable and quiet. I am still within the break-in period, so I have not had a chance to test any other aspects of the tires. They do seem less responsive than my previous Bridgestone Potenzas (which were almost completely bald) but that could be due to tread squirm on the new tires. I would definitely recommend these tires for any passenger car, but haven't tested their performance capabilities yet, so I don't know if I would recommend them for sports cars.
