rear tire wear
Ok starting from the beginning, I have an 06 350z. I don't spin my tires or anything like that I drive normal besides the occasional acceleration while goin down the road already. My factory tires lasted between 10,000 and 15,000 miles. Before I put a new set on I asked a nissan service guy why the back tires sit funny. I don't know whether to say they are angled in or out guess it depends on how you look at It. The top is angled in and the bottom where it touches the pavement is angled out. This causes the inside of the rear tires to wear fast and not even. I was told this was for cornering. My second set are Goodyear eagle gt's and they are doing the same thing. They've lasted between 25,000 and 30,000 miles.I am due for a third set of tires and before I get them I want to know If this Is normal. I plan on getting an alignment regardless. Thanks in advance for any info.

thats because of camber.. Max-G is right... your tires sit like this-> /---\ (maybe not that extreme, but its the right idea i think) right? so the inside (towards the car) wears faster than the outside, correct?
Yeah, that's exactly right. Didn't think about showing it like that but yea they sit like /---\.... My question is, is this normal? Was the Nissan guy right in saying its for cornering?
yes, that is normal. if i am correct, when hard cornering and the weight transfers to one side of the car, the tires will "un-camber" so the tire sits entirely on the ground for more grip around the corner. anyone is free to correct me if i am wrong...
Actually the tire flexes and the tread flattens out onto the ground. Thats why we run so much camber on the roadcourse. We also gain camber as the suspension compresses during cornering, helps with traction.
It's negative camber. In a turn the weight transfer causes a bit of body roll, this will cause the outside suspension to compress. The camber or tilted in tire helps counter the body roll and maintain traction by keeping as much contact patch as possible.
Most daily drivers do alot of straight line driving so most of the time you're only riding on the inside portion of the tread.

Summer performance tires do wear quickly, and much of that wear is due to spirited driving.

Was just wondering if the way the back tires sit was normal and just for cornering because it causes the inside of the tire to wear faster and not even. In all honesty these tires wore funny in the back period. The center wore like if i were to run too much tire pressure which I am not and the inside wore faster because of the way the tire sits. As I stated before I had asked Nissan about the way they sit before I even put these tires on and they said it was normal. Then, some guy from the goodyear place told me my car was out of alignment since the back tires sat that way when I went there to see if i could get the back tires replaced because like I said the center wore. I knew the inside wore because of how it sat but he said the back was out of alignment which caused the center to wear....

Wear is very interesting. Tire appears worn in the area marked. This is an asymmetrical tire and should NOT be swapped. Suggestion: Your next tire should be symmetrical. You CAN swap a symmetrical tire.
