I just replaced my Bridgestone Dueler H/L Alenza with the Turanza Serenity Plus. I was very happy with the Duelers and planned to buy them again but went with the Turanzas due to the lower price and current rebate.
It was raining/snowing/sleeting in the town where I had them replaced (100 miles from home) so I was able to drive in changing conditions right out of the tire shop. As I got closer to home, the weather changed and I was able to drive on bone dry pavement. I've only driven 150 miles on the Turanzas so far but am very impressed. They handled well, stopped on a dime and were smooth as butter.
I am very impressed with how quiet they were. I've read a lot of reviews regarding tire noise but I didn't experience any. As of now, I highly recommend these. If they are this nice with such few miles, I'm very interested to see how they perform once they are broken in.
I plan to update this review periodically as I rack up more miles.
