13'GT Black

My car has 15k miles on it and i noticed all my tires are slight cupped when i was checking my tire life. Is this a characteristic of pirelli nero zero? Its very unlikely my struts and shocks are bad already.

how often do you rotate them? usually cupping can be caused from poor manufacturing. or poor tire care (i.e. low pressures or not rotating them)

also heard a lot of people barley getting 15K out of their pirellies. i think its discussing lol

What pressure are they at?

I rotated them at 10k and as for tire pressure i checked and adjusted probably 5 times in those miles. I can see identation on every other block on the thread. It seems to be cupped on the side and not the middle. Are these tires low quality or something?

A lot of people report low tire life on this forum. Personally, I have had good luck with these. That said, they aren't intended for long life like a normal passenger car - they are high performance. The trade of for performance is tread life.

In my experience Pirelli makes a high quality tire. Pirelli sold me on their products with the Scorpion line, and I have purchased a bunch of tire sets from them. It's quite possible you got a bad set - or there is an issue with your car / something in your control. I'm sure someone will weigh in soon with solid information as to the cause of your issue.

Pictures would be helpful

The stock Perelli's are decent around town tires but not very good on tread life. Cupping is typically a symptom of worn suspension components or alignment. Its not uncommon for a car to come off the assembly line with a bad alignment. Depending on your road conditions, you may also have knocked the alignment out early on. If you trust your dealer or a good shop, have that checked first before you begin replacing parts or continue to blame the tires.

Im not blaming anything, just trying to find out whats going on. I posted a thread awhile back regarding to a bad wheel bearing noise which turn out to cupped tires. I rotated and balanced them at 10k but Im not sure if it fixed the problem. It will probably take too long before its all wear evenly. I just dont want my next tirea to be cupped.

According to this site i have alternate lug wear, its just like in the picture but not that uneven and mine is only on the shoulders of the tread. Their cupping pictures literally has a cup shape across the tread which is not what i have. I find alot of alternate lug wear on truck but not on coupe or sedans.
