You guys think any certain air pressure will help?

 

Help the wear problem? Nissan recommends 35psi cold, my dealer put 32psi in the OE tires. I know, because I checked the next day because I was checking if there was too much air causing the miserable ride. Maximum psi is 44 warm, so thats 39 or 40psi cold, I wouldn't put that much in the tires, especially the OE tires. It would be riding on rocks, IMO. I use 33psi in my Michelin Pilot A/Ss, but I tried 35 recently and I can't feel any difference.

Long ago, we at this site decided uniform tire pressure was critical on the OE tires because the tread was so soft. Not maintaining at least 32psi might cause faster wear was the thought and the OE tires get more mileage with ***** out driving, it seems, and not all do that or maintain the psi uniformly once a week or so. I hated the OE tires before I got the car because I read Tire Rack's Customer reviews, which were bad. My long-winded answer is I don't know for sure but underprssured tires wear sooner on most cars, I have a hard time imagining running more than 35cold. Some run 39-40psi cold. I couldn't do it, they must have cast iron butts.

Iwish I had a better answer, but I don't.

 

Thanks, I'm now running 33 lbs cold and that means 33 lbs at 30 degrees outside. I know that your tire pressure goes up or down 1 lb for every 10 degrees of temp.

 

learned that lesson the hard way too in my G, was passing a slower car in a 2:1 lane setup, just stomped on it and the 2-3 shift must have kicked some wheelspin, 'cause the next thing I know the car is kicking the tail out toward the curb, VDC on.
Back off the throttle, back on and the car jumps straight...had I been to his left I'd likely have fishtailed into the car next to me, not just open pavement.
My Z had no LSD, TSC, VDC - Base as it gets in that area. Would never have pulled that stunt, just maybe chirped the tires and left a pair on the pavement. Now the downside is if you parked with one wheel on snow and the other on dry pavement, you could easily get stuck 'cause the right tire would just spin away.

I think the VDC/LSD is a little overly agressive in kicking power away from the wheel it thinks is slipping, esp. under hard acceleration, IMHO...

Plus, you can't powerslide into a parking place with the VDC on

 

Autoweek just released new info on their 350z long term test:

http://www.autoweek.com/cat_content...._code=08918235


Looking the article over, they rehash the same story as their earlier long term test. I like the opening - seem's like a jab towards the 350z owner's.


"WHEN YOU LOVE SOMETHING (or someone), you can overlook flaws that others, less enamored with your subject, would find objectionable. That’s what happened during the third quarter of the long-term test of our Nissan 350Z"



Thanks autoweek for taking up the issue. Those new set of 18"s must have done the trick.... sellouts

Check out the Motor Week long term test. They say almost the same things as Autoweek. It is interesting how they don't go into much detail about the problems and how there is no fix for it. Looks like at 10k miles they replaced the tires then at 13k miles the tires were feathered again. Yet somehow that is not a problem.......ahhhhhhhhh

Let these people know what you think...

 

At this point, after reading numerous posts that describe the same story over and over again, I think it might be advantageous to look at the issue as a potential class action lawsuit. It is irresponsible for Nissan to try to cover up an issue that is affecting many of its patrons. In addition, it is not only costly but in poor customer relations to expect your consumers to purchase new tires every 9-10 thousand miles. The only way large corporations understand that they have imposed an inordinate amount of grief and frustration on their consumers is by taking the issue up in court. In this manner, Nissan would have to admit to their mistake an compensate those injured by it.

 

Autoweek Quote from Long Term Test:

"....Nissan to issue a service bulletin saying the suspension design/geometry of some models is causing the inside of the tires to wear in a choppy fashion."

First I have heard of Nissan admitting a suspension design/geometry issue with some of the models. OK Autoweek, where is this TSB you quote mentions that. Talk about the Silver Stake/Golden Bullet if it existed.

 

In order to push this along anyway possible, I just brought to the top of the "Repairing Forum" list my thread about Crain/Autoweek's request for our comments.

Have we all sent them an email yet? Now's the time.

 

Here is my 12/17/03 alignment printout ... which is the only one the dealership faxed to me, even though I brought the vehicle in twice after that to be re-aligned because of a crooked steering wheel. They claim that the vehicle was only aligned once, and that it was not aligned the second and third time I brought it in because the alignment was within specification. They also claim that my off-center steering wheel is within the 'acceptable limit' ... it's not accetable to me. BTW - getting them to fax this information to me was like pulling teeth, I had to ask three times before I actually received anything.

Here is my alignment sheet, can someone look at this and tell me if I am OK here?

A little bit anyway...

MotorWeek Long Term 350Z Article

oops...already been posted.

 

I finally brought my Z in for this problem in at 8,973 miles. The road noise started for me right at 7,500 miles. I'm 6th in line to get new tires. I'm thinking my tech was trying to be smart and hit two birds with one stone with me. Because he thinks that new tires will solve the pull to the right and figures I will need two new tires anyway for feathering. So, he got away with only ordering two tires for me since it has taken this long. Well, we all know the tires will not SOLVE the pulling or the feathering.

 

Here's a quick update on my car:

After getting about 1000 miles on my new front tires, the "feathering" had already begun, and was bad enough that I could hear it. This was when I first tried to bring the car back in after getting new front tires. I scheduled an appt and went to drop the car off, but they refused to work on it. After a lot of arguing with the service manager and general manager at my dealer as well as NNA, they decided to try to fix my car again. I had already began talking to attorneys about a breach of warranty case since they wouldn't even try to fix it.

When they finally took it in again with about 1500 miles on the tires, they were obviously getting worse. All they did was play with the toe setting again. I don't know what it takes for Nissan to figure out that playing with the toe isn't going to fix it. I guess now I'll drive around for a while until the wear gets a bit worse, then go complain some more and get one more repair attempt. My patience is wearing thin with Nissan....

 

you guys need to spring for a four wheel alignment at an independent shop of your choosing. look around and find a reputable shop you trust and go there. letting the dealer play with your alignment is like playing russian roulette.i took my car to firestone after my dealer had supposedly aligned it and all the settings for the rear tires were out including thrust angle. that may not be the cause of the problem but it sure didnt help either. we are never going to find out whats causing this as long as we dont know what our cars are set at.

 

Here we go again with the Nissan can't do an alignment thing. And Firestone can? Yeah right, I have all my work done at Firestone. There is only one ****ing adjustment on the car and that is the toe angles. I could do it in my garage with no alignment rack. I have done it in my garage with no alignment rack. On my previous Z's anyway. They didn't cup the tires in 3500 miles. But the 350Z is very sensative to alignment because it is a highly tuned sports car with an aggressive suspension you say? ********. Why is it that, remarkably, only the toe is sensative to alignment on the 350? Everything else that is not adjustable, well, there is some margin of error there right Nissan? Sorry I would be in a better mood but I just had to drive my POS 350Z with my brand new transmission and my feathered tires home from work and feel it banging into third gear on every shift. You suck Nissan.

 

I appreciate your anger sir, but you are wrong about only the toe being adjustable. everything is adjustable but the camber. thrust angle is also important. If you never take your car to an outside shop and only depend on the Nissan dealer you will never know what you have unless Nissan lets you stand there and watch. you dont have to go to firestone. go to a race shop like the other guy said. if i hadnt gone to firestone id be cruising around right now with 98% of my adjustments out of range as my dealer was supposed to have done an alignment and didnt. you have to find out where your car is at. but thats up to you and mine is just a suggestion sir. plese dont be rude to me again or you will regret it.

 

Actually Caster and Camber on the front
When you adjust tow in the rear the rear caster changes too..

Camber on the rear is adjustable to some degree, else you need adjustable Camber rod's like Hotchkis or LSDunique

Bull Dog...

It must be the Strut's and shocks

I think the fellow that put in G35C struts an Shocks is the fellow we should ask that question. Sorry I don't remember his handle/name...

Ok, let's not get at each other's throat people, we need to get at NISSAN!!!!. They are suppose to have a car show/conference here in Nashville over the summer, I say we all show up and throw our old tires at 'em.
