Very good tire for the value. I used them as go-flat replacement in my BMW with sport suspension and 18 wheels and the ride was much better in terms of comfort and noise with almost no difference in handling to the original run-flats. I am using them in my MB and just bought 2 extra ones to replace front tires (rear one have 3000 miles) which are the previous General model but with 30k in them.
I recommend highly this tire. However, I must say that the General tire model they replaced (Exclaim UHP) somehow felt they had better handling. Pity General discontinued it.
