About five hours because I'm slow like that.

Took off all the wheels so I could inspect for punctures, wear and to wash 'em throughly. After roughly 7,500 miles the fronts look great! Even wear on both tires and they look almost new. The rear tires are a different story however. I took the car into the dealership for my last free oil change about seven months ago and had them check brake pad wear and alignment because the car was pulling to the right. Everything was within spec limits including rear camber. My question is that is it normal to have almost no wear on the outside part of the tire and have the inside worn so that the area highlighted in green in the attached picture is almost bald?

Oh, I also washed the car.

BTW, stock 18" with Michellin PS rubber: rears weigh 52 lbs and the fronts 48 lbs.

 

It's because you have negative camber, get a rear camber kit to straighten the wheels out and your problem will be solved. Just because the rear camber was in spec doesnt mean its not out. The specs infiniti uses are the specs all g35's come with.

 

Problem solved, but how will the car handle when you reduce its camber? The car comes from the factory with negative camber dialed in. I admit the Pilots should last longer than 7500 miles, but I really don't know your driving habits. If they are somewhat aggressive, then reconsider taking out your rear negative camber unless you know how to deal with oversteer. The dealer did say everything was in specs, so it goes back to your driving habits.

 

it's not camber in your case, it's your toe setting.

the car comes with a lot of toe-in from the factory. have your car aligned
with milder toe-in if you want tire longetivity. straightline stability will
diminish a little, but unless your car is lowered it shouldn't make much of
an issue.

 

I have 20k miles and I haven't changed my tires yet.

 

Ummm, negative camber means it LEANS inwards, causing the INNER portion of the tire to wear out quicker, as seen with dropped vehicles with no camber adjustments. His car has a stock suspension, so it might just be a simple alignment to do the trick. Ever hit any pot holes real hard Eldridge? And yes, the toe may need to be adjusted. But you DON'T need a camber kit.

 

Adjust the toe? G35's have significant negative toe? Did you measure this? Just looking at the car I never noticed that. If you adjusted the negative toe, the car would be a bit faster too.. correct me if I'm wrong.

 

Hehe, I think there's a little bit of confusion about my post. My car has negative camber--I can see it. The part of the tire I highlighted was meant to show what part of the tread is actually worn on the _inside_ part of my tires. I couldn't get a shot of a Pilot Sport's tread head on so I used that picture and highlighted the outside part of that tire to show what was worn on my tire.

I haven't hit any potholes and the wear pattern is the same for both rear tires which leads me to believe that it's a stock alignment issue. What I really want to know is that should I go somewhere to have the tires rotated? I'd also like to point out that the tire on the inside is not completely bald... It's only worn to the point that the particular grooves (highlighted in the picture) is almost bald. The larger grooves on the inside are still about 80% after 7,500 miles.

 

Do you know what your rear specs are? You might be on the extreme negative side of the specs, which is -2.0.

 

I'll try to find the sheet when I get home. They've got to be somewhere with my records of the car. I will also snap some pictures and post 'em up.

 

yah, Ive never seen "negative toe" on any car either.


toe is measured in or out in degrees, mm, or inch.
camber is measured positive or negative in degrees.

 

Here are some pics to better illustrate.

 

whats up Eldy? You get socom 3? if so throw me on your friends list.. SkyLineG35 is the name

i'll say it again for people who dont know. i worked at west hou infiniti over the summer. i would go out after work and look at all the used tires out there and see if there were anything good enough to drive on or waste away for the weekend. i noticed this exact same thing on every single coupe tire out there, stock tires or not this is something that happens.

getting the proper alignment and looking at the spec sheet to see where your car is at right now will help you. unfortunately, you cant rotate the wheels. wheels up front are 18x8, rear is 18x8.5. what you could do, since they are directional tires, is have them take the tires off teh back wheels and swap them. this will allow even wear. in an extreme situation, you could always drop the psi of the tires by 5psi(~28psi). This will help even it out as well as giving you a larger footprint from the tire.

hope this helps
