Tires loose air pressure at unacceptable rate, constantly having to re-inflate. All 4 loose air at same rate (about a pound per day if vehicle is parked, 2+PSI loss if driven). Contacted Nokian but no response. Gotta go, time to re-inflate again.

At first I thought that they were louder than the tires they were replacing but I soon realized that they were making a higher frequency noise so they were more noticeable. After a couple of hundred miles they have quieted down to a point that I don't notice them with the radio off. Recently I drove through flood conditions hitting water occasionally 4 to 6 inches deep at 35mph and I had complete confidence in the car and tires.

I replaced some Goodyear Assurances with the Nokian One. At first I was angry, I thought the Nokians were noisier than the Goodyears until I realized that the sound was a higher pitch and there for was more noticeable. After a couple hundred miles, the tires are either quieter or I have gotten used to that sound frequency. I sometimes turn the radio off and listen to the tires and road noises and I find them quiet for the different highway surfaces. They handle quite fine for tires on an SUV.
