if you were to look at the tire. Back right in which color would tire feathering appear just need simple answers.

 

In some cases feathering can occur all across the tire. Generally it is in the yellow or green sections (the outer sections of tread).

 

Mine always happened in the yellow.

 

Look at the inside tread. Compare to the outside thread. You can see that some of the blocks are high while others are low. Run your hand along the inside. The edge of the tire feels “cupped” or “feathered.”

 

So if i was getting fat abnormal wear in the pink and some blue portions would that be due to offset camber? im running proper psi at around 35 they are just eating tires like a monster. or would this be considered normal wear

 

That really sounds like your psi is higher, making the center bow out more rather than feathering. But if your psi is where you say it is, I don't see how that could be the case.

Feathering will have the pattern in the picture shown above, with alternating light/dark marks on the inside or outside of the tire.

Camber will typically wear down the inside of the tire faster than the outside but it will be even without alternating patterns. (assuming it's negative camber).

 

No if he is running 35 PSI, that is way too high. I just replaced my stock REAR Bridgestone Potenza's on my 06 350Z and I ran it with an average of 30psi since that is what a lot of professionals recommend. There was a lot more wear in the center of the tire when there was still more tread left on the outsides which tells you the tire is over-inflated. When I got my new tires, the shop set them to 35 and it was raining outside, I thought 35 was really high but I gave it a shot. I would spin soooo easily just average driving, like 3000rpm , if u gassed it slighty too sudden, even if u hit only 3k rpm, I would f*****in spin, it was annoying.

Anyways my point is you wanna run around 25-27psi (below 50*f)on the rear and maybe like 30psi(also below 50*f) on the fronts still since fronts aren't drive tires and front tires bare more weight with the engine. Set your rear tires to 25 PSI if it is cold outside, set them to 30psi if it is warm or average outside, and if its a really hot summer day maybe set it to about 33psi. Temperature makes a huge difference. Air expands and contracts, where I live, temperature lately has fluctuated from below freezing to as high as 70*f. With that much temperature change you will notice a 5psi difference easily, and with your tire pressure monitor built into your 350Z, you can watch it happen.

And yes 25 psi is fine if you like to burn rubber, I love burning rubber, I drift sometimes, very fun stuff. I also respect a drag here and there especially if some hot shot is daring me at a stop light. 25psi gives me nice grip if you hit it at 4-4500 rpm, and if you wanna break the grip for a drift, just rev that **** to 6000. 25psi rear/30psi fronts on my Z seems to be an ideal all-around psi setting, safe in the rain too.

These are my experiences on my 2006 350Z Enthusiast. It might be different among tires of different compounds, treads, and sidewall depths, I am only talking about the stock wheels and tires.

 

i would disregard the top post. You have to think that you are pressing the gas in cold weather. Wheel spin will be there. 36 psi is right with my stock tires. I don't ever have wear in the middle..or non for that matter.
