Gang,

I think that we may have a major problem with the “Z’s”. I have been noticing a loud roar in the car as we slow down to a stop. This has been getting louder and louder as time and miles have increased. We now have just over 4900 miles on our Redline Touring 6sp and the front tires are JUNK!! The insides edges are “Cupped” badly and are worn beyond use. I spoke with my Dealers Tech this afternoon and there are no TSB’s out on this. He told me that he had hoped that Nissan would have this problem fixed with the new 350Z. He said that this was common problem with the 300ZX and I got the impression that there never was a true fix on those cars. Check your tires and let’s get together on this one so Nissan NA can be contacted for a fix. If we don’t act as one on this problem, we will be putting new tires on these cars every 5000 miles or so out of our own pockets. So like I said “Check your front tires NOW!”

 

Call BS on them. I have ~5000 miles on my Z and am not experiencing any issues with the tires or with excessive road noise.

Take it back and tell them to make the measurements as shown on pages FSU-5 through FSU-7 of the service manual. The actual measurements are on page FSU-21. Ask them to provide you the results in writing so you can complain to NNA directly.

 

Did they check the alignment? If the wear is only on one portion of the tire, that could be a factor.
