I currently own a 2004 Nissan 350Z and I'm experiencing a problem with severe front tire feathering. I have made Nissan aware of this problem which cause a loud roaring noise and vibration during braking. I originally thought the problem was my brakes but after just 10K000 miles replaced the front brakes and realized this did not fix the problem. After my second time to the dealership I was informed that my front tires were no longer good and need to be replaced at just under 14000 miles. I was told that this was a design flaw with the tires and possibly a toeing problem with the Nissan 350Z's. I registered a complaint to Nissan at 1800-Nissan-1 and it doesn't seem as though they will resolve this problem. This problem also occured with 2003 350Z's.

First noticed by vehicle owner at approximately 10000 miles, dealer confirmed at 12000 miles, my 2004 Nissan 350Z touring model has developed abnormal wear of inner edges of front tires--front tires forming a cupping shape. The result of this abnormal wear has created unstable handling and ride, but most importantly a safety concern with regard to tire performance and handling. Nissan has issued a service advisory bulletin acknowledging this very problem for the 2003 350Z mode, but not for the 2004 model. Nissan has indicated that the suspension is the primary problem for causing the abnormal tire wear and has authorized a partial fix to the problem. Nissan refuses to acknowledge this problem with the 2004 model--request investigation for safety concerns and consumer protection.
