Front tires are cupping on the inside due to issue with car. I had the car with 7,000 miles on it when I notice problems with noise and handling. At 11,000 the deal said it need to be re-aligned which they did and flipped the tires. Now at 16,000 miles I have cupping on the inside and outside, which causes noise issues and handling problems. I'm taking it back to the dealer I have had enough.

Suspension of car causes tires on the front of the vehicle to wear unevenly. Tire tread feathers and a loud roaring sound is very noticable. I took the car to the dealer back in the spring to correct the problem, but it has now returned.

I have a suspension problem with my 03 350Z. It causes tire feathering.

- Jefferson City, MO, USA

My 2003 Nissan 350Z has a suspension problem. I had tire feathering on the front two tires and they were replaced by Nissan and the alignment was redone. Now the tires are feathering again. This seems to be a widespread problem with many of the first production cars. I would like Nissan to address the problem and issue a recall of the cars so that the suspension can be fixed. I do want to have to replace tires at 6-10K miles because of this problem.

- Bridgewater, MA, USA

I also own a 2003 Nissan 350 Z and have experienced the tire cupping/feathering. I have had the alignment at 4970 miles and tire replacement at 7500 miles due to the backorder of the tires because of so many others also having the realigning and tire replacement.

Suspension problem causing improper tire wear.

- Fairview Park, OH, USA

Excess abnormal wear to the inside edge of front tire tread causing alignment, handling, and excess road noise problems. First sign of wear appeared at around 3,500 miles on the new vehicle. Four-wheel alignment was performed at 4,000 miles. Abnormal wear continued after alignment. A "side-to-side" front tire swap was performed at 6,000. With less than 9,000 miles on the car, abnormal wear has again appeared on the inside tread along with excessive road noise and erractic handling on crowned roads.

- Murphy, TX, USA

Suspension design flaw creates uneven tire wear in the front tires. Tires will 'cup' or 'feather' within the first 10,000 miles of driving. My car in particlar ran out of tread on the inside patch at 13000 miles. Changing tires is not a cure for this issue as it reoccurs due to the suspension. This is a potentially dangerous flaw as it might cause vehicles to lose traction in wet/slippery conditions.

Tires are wearing out incredibly fast. Handling is compromised.

Nissan 350Z tire feathering problem believe to be related to a problem with the suspension.

- Glendale, AZ, 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.

- Kannapolis, NC, USA

Nissan's 350Z's suspension causes front tires cupping on the inner edges of the tires. This is the source of that loud roar you hear when you brake from about 30 mph to a complete stop. Nissan only offer to realign the suspension and replace the cupped tires but not addressing the suspension issue. The problem is caused by a desgin flaw in the suspension of the Z. it is not a problem with the tires as any tire you put on the Z will eventually start to cup again.

- San Diego, CA, USA

Suspension problem with 2003 Nissan causing tire cupping every few thousand miles.

- Adena, OH, 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

Front tires on my vehicle are feathering due to suspension problems. Manufacturer will not fix the mechanical problem. It is a Nissan 350Z 2003 under warranty with 7800 miles. I have had numerous tire inspections by different tire manufacturer's, all point toward suspension defect. Traction is less then 100%. Nissan is willing to replace tires but will not fix the actual problem caused by a suspension defect with this vehicle. Tires need to be replaced every 6000-8000 miles due to extensive wear. Car pulls to right excessively. Car is loud when driving and braking. Car is not safe to drive.
