Made it to the first oil change after installing these tires. My vehicle is running these tires in 225/40ZR18 size on 18x8 2008 model Eclipse wheels on lowered coils. I drive the snot out of my car. I push it really hard in the corners and so far these tires have not started to slip yet, grip is excellent. No signs of obvious wear either. The 2G Eclipse is a fairly noisy car in terms of road noise. These tires are by far the quietest performance tire I have had on it. Haven't had a chance to test winter grip yet because this year we had no winter in Indiana, seriously, no snow at all, no ice, nothing that even stuck to the road. I do all my own maintenance when possible. Just rotated the tires myself and went over them good. Nothing bad at all.
For those who feel the tires have weak sidewalls, try upping the air pressure, you will get better MPG to boot. I run 45psi all around which might sound tight but they perform really well here. I have noticed what I believe is minor flat spotting overnight, but it is really minimal at most. Hardly as harsh as some reviewers make it sound, but that's a perception thing. Great tire so far, will have to follow up when I make it through winter.
