Here was a good test review done on Vredestein tires against other top manufacturers. Vredestein are more known in Europe and are becoming more popular here in the states usually with German car owners and are priced very competitively. Anyhow take a look and something to perhaps to consider with your next tire purchase. I am!
I'm surprised they didn't review any bridgestones. My favorite tire for grip is the potenza re050a. It's a nice soft compound that's nice for daily driving and it's really predictable. Only downside is it's really expensive haha.
They are great tires, I have them on my car, they are quite expensive about $1200 for the set for me.
