Correct me if I'm wrong but if his camber caused that, he would have been running on a positive camber. The wear is on the outside of the tire so the tire would stick out from the top a bit, right? Maybe Tay's wheels are set toe out?

I currently have a similar problem but my wear is on the inside and thread is showing down the center. The toe setting is pointed in, which I think is the culprit.

 

READ this Thread!

all that wear is on the inside of the tire, on both the rear tires. The FR tires are new perfect also.

So even through I have had two alignments in the last 6000 miles that still happened.

So what Im being told is when the alignment was done it was either done incorrectly or it was even done at all, correct ?

I know about the straggered directional rotation stuff and I have read alot on the camber issue, I was just VERY suprised to see that bad of a wear after just 600miles and two rotations.

how did you rotate them?

 

this is a copy from that other link...

There has been some question on how to Rotate tires on the 350Z

(Or Any with Directional tires on a Staggered setup)



Forward:

On a vehicle with Negative Camber the Inside of the tire naturally wears more then the Outside. This technique will prolong the life of your tires.


When to do this?

Once the Inside of your tires being to show Tire Wear. If the Outside of your tires look brand new then do this just before the Inside of the tire reaches the Wear Indicator's. If the vehicle is driven in hard corners or on the track so the Outside shows signs of tire wear the sooner this technique is done, the more even the tire wear will be. Make sure to do this before the Wear Indicators are fully worn or the Tire Cord begins to show.

What will I gain from this?

If this technique is done the Tires will last almost Twice as long! (depending on driving habits of course)


How To:

STEP #1

Dismount Wheels from the Vehicle.

*For Explanation Purposes we have labeled the wheel & tire:

Front Left = #1
Front Right = #2
Rear Left = #3
Rear Right = #4

Image 1A displays the wheels before this technique is performed on the vehicle.




STEP #2

Put Wheel #1 on the Tire Mounting Machine. On 95% of wheels the face of the wheel points up (the out side of the wheel will be facing up) ((in cases of Reverse Mount wheels (Racing Hart etc) the wheel will be upside down / outside facing down))

Dismount the Tire from the wheel. Flip the Tire over so the Inside is now on top.

Mount the tire so what was the Inside is now on top and the Outside is now on the bottom.



Repeat for all wheels.


STEP #3 Time to put the wheels back on the car.

Since we flipped the tires they can not be put on where they were originally. The LEFT FRONT #1 will now have to be mounted on the RIGHT FRONT position. The original RIGHT FRONT #2 will be in the LEFT position.



Notice how what was the FRONT LEFT #1 wheel is going the Same Direction only on the FRONT RIGHT Position.

The illustrations display the Number Box on the INSIDE of the tire. The Arrow shows the Direction of the tire.

This technique can not be done with Asymmetrical Tires like the BF Goodrich KD TA.

This technique CAN be done with the OEM Tires to get more life out of them as well as popular tires like, TOYO T1S, POTENZA S0-3, BFG KDW 1 & 2, and other Directional Symmetrical Tire.


Sorry about the chicken scratch images, I do not have photoshop at home at the moment...

 

Im thinking they didnt rotate them correctly, so thats how I endded up with to blad rears

Im going to print out and give this to them next time, thanks for the help Jason

Incorrect TOE settings will cause faster tire wear than just negative camber alone.

Incorrect TOE settings + too much negative camber...say bye bye to your tires in a couple thousand miles.

 

the only other way they could have rotated them would be to just put the left wheel on the right, then the rotation would be wrong... YOu probably would have noticed that...

The method I describe above will get more life out of your tires...

and best of all is cheaper then a camber kit./.

 

quote tay "suprised to see that bad of a wear after just 6000miles and two rotations"

okay i'm confused, if your that diligent to rotate twice in 6000 miles (who does that?), how could you not notice the uneven wear.

and to answer your question - IF, in fact, you did have an alignment done at all, it was done incorrectly. post a scan of your alignment sheet.

pp

 

Well first I have to find the sheet, second I have a 2 year alignment deal and thrid I dont handle the tires, they are tucked under the fender.

The wear was all on the inside, and hearing the BS I was geting feed about the toe being perfect and cra*p I endded up with this.

Luckily I notice before a tire blew on the freeway

T

 

whats wrong with rotating every 3K instead of 6K if its paid for, and if its better for the wear of the tires

T

 

I have a feeling they told you they "rotated" but didnt do anything...

common...

 

tay - if its free, sure why not. my point is if your diligent enough to rotate that often then you gotta figure your diligent enough to check your tires. if you aren't the type of guy that checks his own car, then okay..... your shop failed you on 3 points.

1. they either didnt do an alignment, or did it poorly
2. they didnt rotate your tires....
3. and if they did, they failed to recognize or notify you of uneven wear when they rotated the tires (any reputable shop would tell you this)

sorry to hear your situation and yes, it is good it happened in your driveway and not the freeway

pp

 

oh I think thats it too

T

 

Listen to this guy! ^^^

Camber shouldn't chew through the tires THAT quick???


I still say bad alignment, bad toe settings.

 

yeah, i had the same type of wear on my fronts, actually my tires were t1-s and were showing a lot more threads on the inner 2 inches of tire. I had bad toe settings too after installing the nismo suspension kit. I didn't notice any noise or any weird handling characteristics with the bad alignment, but after doing an alignment seemed to have less bump steer. So far my T1-R's seem to wearing pretty evenly.

 

They're fine, just a bit of black paint, and your sorted.

 

ok well after I get the wheels fixed and a new color on them Im going back to my suspension shop have the toe looked at again.

thanks for the insight everyone

I dropped my Z using the Tanabes (from mynismo.com of course) After dopping the springs I gave the car 1 week to settle then took it in for an alignment.
The fronts were ok, however the backs, no way in hell could they pull them out anywhere near factory specs. from the back my rear wheels looked like / \
ok maybe not THAT bad but it was pretty darn bad.

1 camber kit later and all 4 wheels are almost within spec, still not 100% but damn close.
