These goodyear are overall good tires, i bought them because they were OEM on my bmw 535i. My overall experience with them is Fair-Good, due to the point that are are not quiet as they said while driving on highway speed at 70mph but when you reach over 80-85, they are good, not sure why... i have to get them rebalance more then 3-6 times from different shop to get that good smooth ride.
These tires come as OEM for my BMW 535i 2011, when time for replacing i decided to go with them again witch i did. The overall, they are very good tires even without balance they still run good. I do noticed, it depend on where you get it install and balance and what type of weight they put on it to give it a good smooth rides. For me, i got it get it rebalance from 2-3 place before it actually run smooth. Until one time, i decided to put the weight on myself and now it run extremely smooth at even high speed. Here the secret i had discovery... it may or may not work, but for me it work and i put over 1000 miles on it so far and it still run smooth..
I have never really gotten the performance out of a run flat tire that I am looking for, but these Goodyear Excellence tires are the best Ive used.
