I purchased a set of these tires just over a year ago after getting a flat while driving to work. After lots and lots of research, breaking down the Tire Rack test results and reading every single review, these stuck out the most. I was willing to give up a (very) little in the performance department for an increase in ride and noise comfort, and the price was well below competing tires. All in all, I'm very pleased with my decision.
Handling, dry/wet traction and road noise were all significantly improved over the Goodyear Eagles that had been previously on the car. It would launch with more authority and even allowed me to run an 8.833 second 1/8th mile at Qualcomm Stadium in San Diego. This run was done in cooler temperatures and with lots of wheel spin in 1st and 2nd gears, but what can you expect from a drag strip that doubles as a parking lot and using non drag tires? Overall, I'd say not bad for a comfortable tire that's reasonably priced.
As for my driving impression for other than a straight line, grip is very good that's both predictable and controllable at the limit. I can regularly go twice the suggested speed for most curves without fear of excessive understeer or breaking loose and have maxed my car's g meter at 1.14 during a blast around a right handed on ramp onto the freeway. I would have NEVER attempted those feats with the old tires for fear of completely losing control.
For as many miles as I've put on the car in the last year, I'm pretty pleased with how they've held up. They will get some flat spots overnight in cooler weather, but nothing too significant and it goes away after a few miles warm up. In my opinion, it's a great tire for the price and you won't be disappointed. For my next set though, I am considering stepping up to a 265/40 to increase the grip and traction a little more. Gotta to do something to rein in those 400+ horses..
