Bought a 1999 Honda Accord 4-door V6 with these tires on it 23 months ago.  Tires had about 10k miles on them.  I've put @68,000 miles more on them, and they still have probably 10k miles to go - these tires are unbelievable!

I have had them rotated and balanced about every 12-15k miles. 

I do a lot of highway driving with my job, and these tires have been awesome - very very smooth at 75+mph, with an acceptable level of road noise.  Excellent handling in all road conditions in TN/N. Alabama.   I really couldn't ask for a better tire, and will be purchasing another set without any thought...
