My front tires have been cupped and or feathered on the inside. It makes a very load roaring noise when coming to a stop. I don't feel safe about my car due to its handling. The tire wear is very uneven.

Various things gone wrong with this car: -rack and pinion / steering pump failed at 4000 miles. Car refused to steer when at idle. Very dangerous. Replaced under warranty after 2 weeks. -two transmission replacements. Second transmission replacement requires new flywheel, clutch disc, and pressure plate. Both under warranty. -uneven tire wear. Dealer told me that I'm a "young speed racer" and that I need to "slow down". denied my appeal for new tires, I bought new, wider rims and tires, alignment, and problem went away. Tire sizes are 245/40/18 and 275/40/18. Bridgestone potenza S03. No feathering after 11000 miles. Unfortunately, this car is not very safe... and Nissan service / customer service is very uncourteous and rude in their approach to the situation at hand.

I own a 2003 Nissan 350Z. I purchased the car on July 3rd, 2003. Since that purchase, the front tires have been "feathering" and all Nissan will do is pull the tires off and rotate the problem area to the outside of the wheel. Now the inside will start to "feather" thus creating the ride even rougher and more unstable. Not only is this causing excessive wear to the tires, but once rotated, it has increased the chance for a blowout even further. Nissan continues to Dodge my request for a suspension adjustment, as this is apparently the problem, by saying that it is not the suspension or the alignment, but the tires themselves (which is just not true.

Nissan 350Z-2003 with 7,500 miles. Experiencing tire feathering/cupping on front tires due to vehicle alignment being improperly set at factory. Excessive tire roar and shake.

- Barre, VT, USA

Nissan 350 Z owners have a severe problem with the suspension of there new car. Nissan is not repairing this problem. They have addressed the issue with a tsb. This repair is just enough to get the owners passed there 12,500 mile warranty. The problem is that there is no adjustment for caster or camber on the 350Z. The cars left the factory with an alignment problem, and there is really no repair available. This has left all 350Z owners, replacing tires almost every 6 months.

I have owned a 2003 issan 350Z for almost 1 year and in that time I have had several problems with the car that Nissan denied until pressed. The tire feathering problem is well known but had been denied knowledge of the problem when speaking to Nissan. The radio in the car is also a well known problem which they also denied any knowledge of. They replaced the front tires but mamy people have stated this problem will return. I deserve a guarantee that if this problem persists that Nissan will replace the tires as needed.

- Tallahassee, FL, USA

Tires cupping on the inner edges. Loud roar when you brake from about 30 mph to a complete stop. I think is a suspension problem because the 2004 cars don't have the problem.

- Taylors, SC, USA

Tire feathering on my 2003 350Z after 10,000 miles. Brought in to be fixed by dealership at 13,000 miles. Still have problem and trying to get 2 new front tires with little luck at 18,000 miles. Inside of tires are feathering again and I'm think this will cause a major loss of traction, especially in rainy conditions.

I have a 2003 Nissan 350Z that has exhibited abnormal tire wear on the front tires. The symptoms include cupping/feathering on the inside of the tread and increased road noise/roar. The noise appeared at 5,000 miles on the odometer and worsened. I took my car to star Nissan in niles, il, and they told me they were ill-equipped to perform Nissan tsb #ntb03-006 (tire road noise when braking). I called Nissan Consumer Affairs and informed them of the problem and I will try another local dealer. When I asked if tires would be replaced if the tsb did not solve the abnormal wear, the Nissan representative told me that I'd have to call them back if the problem persists.

Front tire wear, due to bad design, seems non correctable.

Tires are cupping/feathering and will not be acknowledged by Nissan North America. I believe this will provide for a situation that could be hazardous. The solution provided by Nissan is to have the tires taken off the rim and rotated, as well as performing an alignment. The problem continues to persist even after this action was taken. The tires are brigestone RE04's - feathered at 5,000 miles.

My 350Z had a terrible growl noise and vibrations coming from the front when braking. Tires were very feathered on the inside of the front two tires. Filed a complaint with nna and they had the dealer take the tires off the rims and swap the front tires. I don't think they fixed the issue just delayed the inevitable.

Front tires feathering. Return to dealer. Dealer rotated tires and redid alignment. Was told to go to a frame shop. They say it is so far out of alingment they cant fix. Caused by pot hole? other Z owners have the same problem of feathering.

I am concerned about my Nissan 350Z suspension/tires. I have been reading a lot of bulletin board entries on www.my350Z.com and www.zcar.com about vehicles manufactured before Dec. Of 2002. I also visited the Nissan website and see that there is a tech bulletin posted about the wear on the tires. There appears to be an issue with the suspension set up on the 350Z that is resulting in excessive wear on the tires or feathering. There are a lot of pictures on the www.my350Z.com website of actual tires. The feathering seems to begin anywhere from 5000 to 10000 miles.

Tires feathering very badly on all four tires.
