UPDATE - A definitely wanted to let everyone know about this.
Sidewall flex with these tires at high speeds is VERY apparent.
I am going to try and increase the PSI to see if that helps, but I won't like, it feels scary weaving on the highway at speeds of 80+. The sidewalls are definitely softer than my liking.
Weird that someone found noise to be an issue. These are (IMO) very quiet, but to each his own.
Had a chance to drive in the rain with all 4 tires and they are superb.
I'm just concerned about the high speed performance at the recommended PSI.
