Knew these were everything I hoped for before I got off the tire center parking lot and to the first traffic light down the main street. Had run Fuzion tires 47,000 mi in 3 yrs so everything the TIRERACK ratings said about these Serenity Plus tires was immediately evident---QUIET, SOFT, SMOOTH RUNNING, LOW RESISTANCE, allowing me to let off the gas way sooner than before when approaching any reason to decelerate or stop. Both my wife and I wear double hearing aids, so the lack of background tire noise has been a real blessing to us. The 1300 miles of this first month included 400 miles interstate TX to KS and back again. Have nothing but praise for the tires and, again, the reliability and accuracy of the TIRERACK evaluations.
Had previously twice selected tires based on TIRERACK evaluations after OE ones on new 1999 Mercury Cougar wore out at 37K. TIRERACK choice with wider tread gave me 87K off two sets of 40K tires and fantastic road gripping on curves and cornering.
Have only driven these new tires in dry and light to moderate rain conditions, thus the N/A ratings on hydroplaning and snow. Did find that on county gravel roads in KS I had to drive 5-10 mph slower than before, as the extra-deep (and softer?) tread really grabbed the crushed limestone and threw it up under the car. Son-in-law in his Suburban following me asked what happened that I cut back our usual speed and maintained the lower speed on the gravel portion. Gravel a very small portion of our driving, so still say these tires are the best, at 75K warranty and UTQG rating of 600. Thanks TIRERACK.
