I have them, and i couldn't disagree moreThey grip AS well as my kumho 712s in the dry, havnt driven them in the rain yet, but i expect them to handle it fine. They have a large water groove. They also ride a lot smoother than my 712s did. The 712s would NOT balance properly and i had vibrations at highway speeds. The 512s balanced perfectly.
The only thing negative about these tires is they have noticeable tread squirm with their tall tread. It can be an odd sensation at first to feel the car squirm during turn-in, but after they set they grip really well. I'm sure as the tires wear down they will have less squirm, but honestly it doesnt really bother me for driving on public roads. I plan on getting a set of Azenis for autox.
Did I mention that they have pretty sidewalls and a rim-guard lip?
They most certainly are. They are listed as an "all-season ultra-high performance tire"; i.e., wet, dry, and snow. They are NOT a dedicated summer-only tire. And, as I stated, I was comparing their snow performance to the many other high-performance all-season tires I've used on the three cars I've owned. I think with the possible exception of a set of Bridgestone Turanzas I had on my 1991 Escort GT for a while, they're the worst in the snow I've ever used.I have them, and think they are better than the 712. As far as the squirming, Falken has always had a coating on the tire that wears off after the first 500 miles(It's what the tire dealer told me) So you need to be careful until it wear off. They are a great wet and dry tire, but not for snow, and since they are not made to be used for snow, I dunno why some of you would use them in the snow and then complain that they suck.
My driving is 97% expressway (by miles), so I don't know how my results will compare with what you might get. I put about 40,000 miles on my car a year, and they lasted 1 year. I probably could have kept them longer, but I don't like to push it. I do too much driving to use tires with very little tread left. They wore out faster than other tires I've used on my other cars, but they also grip better in the dry than the other tires I've used.Since you're on your second set, how many miles did you get out of the first set?
