I've got P6000s (215/60/15)on my car right now. I've had them for about 4000 miles with no problems. I replaced these as soon as i got the car, and I have no expierience with any other tires to offer a comparison. From what i know, they're a great tire. I've never had a problem in wet weather. In fact, i cruised through the entire state of Geogia on Route 75 going 100 in the pouring rain without one slip.
They were expensive though, $115 a tire, including mounting and balencing.
Someone mentioned that they lose their round quickly. Which might be why i've got the steering wheel shudder. Something i'll look into.
