Hello im new to the threads first post with my newly purchased 06 350z. okay let's start when I first got the car it had 19 inch rims, 3 days after I got it. my front right tire went flat, after taking off the tire I noticed the inside of this tire had worn down faster than the rest of the tire ( the tire had about 50 to 45% of the tread and the inside was so bad i could peel the rubber back on itself). I took it to the dealer that I got it from and they took it get an alignment and I was told everything was aligned right. Two months later I had to do the same thing to the front driver side tired it had the same wear just not as bad because i caught it soon. I took it to the tire shop, as the tire was offI looked at the camber and suspension and didn't notice anything fancy both stock. Now I'm wondering do I have to change my cambers or my suspension to get rid of this problem. Has anyone ran into this problem?from research I don't think you can adjust stock cambers ,anyone have any ideas thanks

These are pictures of the second tire

 

factory camber is not adjustable in the front.... you would have to buy aftermarket upper control arms and then even still shops wont touch it because according the the computer the front camber is not adjustable, you would have to take it to a tuner shop

 

that's what I was thinking any suggestions for a good upper control arm kit. I worked on transams before this taught me a lot about working on cars, the do's and don'ts. I'm pretty sure I can put it on but am I going to need an alignment after ?

 

they are pretty straight forward and easy to install. i had the spc's on mine but they are not easily adjustable. friends have the kinetix and they are easily adjustable, each turn in is a certain amount of degrees... cant remember off the top of my head what it is exactly

 

I just came here because of the cambers. I don't have anything more to say than what travlee said. That looks an awful lot like camber though.

 

Okay - you have a serious issue here.

This is called cambers.
You can thankfully sell your cambers on ebay for roughly $20 USD per 0.1 degree.

Or, I can sell you some of my cambers?

 

You probably have a bad bushing and it's not holding alignment

 

that too... going to say lower inner

 

Agreed. It looks like toe wear and not camber wear. Which makes me think you have a bad alignment(toe wise) or bad bushings that allow for an extreme amount of negative camber on the inside tire in a turn. Check compression rod bushings and lower control arm bushings.

 

Alright ill get it jacked up as soon as i get off work. Thanks for all the suggestions ill be sure too look into them.

 

if the lower inners are shot... the arm will not be centered..... this happened to mine

 

I have the same issue on both of my front tires, my right side being more extreme. Alignment didn't seem to help with the issue at all since I've had this problem with my other set of tires. Is this solely due to bad bushings or the lack of front camber arms? Or can this also be caused by a suspension issue as well?

In addition, my driver's side rear tire has a very slight, wavy wearing pattern on the inside-- I can hear "warbling" noise while driving. However, the tread seems to be wearing fairly evenly through the whole tire so it doesn't seem to have the same issue as my front tires.

Can anyone provide any additional information on what might be the cause of the issue and if there are any reputable shops that can handle this? I don't have the technical mechanical experience to troubleshoot the issue and any help would be appreciated.

Right off the bat, your first picture has an awful lot of cracking in the main groove. I'm betting this is a pretty old tire and should probably be replaced (hope you already did). Check out this article on checking date codes: http://www.tirerack.com/tires/tirete....jsp?techid=11
Shouldn't be rolling around on any rubber older than 5yrs.

Is the car lower than stock at all? while things may look factory, a set of H&R springs are black and can wind up on the stock struts.

When you had the alignment checked, did you get the numbers? is it a reputable shop? Always ask for the paperwork, as it will help you diagnosing problems and you can hold the shop accountable.

Regarding the lower control arm bushing, that may be causing your toe issues. This thread outlines what a failed bushing looks like, as well as how to replace it if you should feel like trying to tackle it yourself.
