TRY AGAIN GENIUS!

When I changed my tires on my '04.5 coupe the fronts were worn to 2mm on the inside edges while the outside edges still had 10mm. This contributed to the loud thumping noise while driving. Reason - one sided wear due to the camber. Here's a clue for you - check out this web site for the facts: http://www.procarcare.com/includes/c...dtirewear.html

If you can't base your opinion on facts, please, keep your mouth shut.

 

The problem with our tire feathering seems to stem from a negative camber issue. Since the camber settings are not adjustable, nothing can be done other than changing control arms which are super expensive, finding a camber alignment kit, good luck! or modifying the settings through a specialty alignment center. Any of these things can be costly. Our tires are performance tires and although do not last very long (12-15,000 miles) they are not totally to blame. They will get noisey when they are at the end of their lifespan but signs of wear with low mileage on them is a sign of an alignment/suspension problem. Also, unidirectional tires seem to be more susceptible to the inside feathering. One thing I have learned is that getting our cars aligned within manufacturers specs does not mean our cars will not show tire wear. Why aren't other sports cars plagued with the same issues? There seems to be a design flaw similar to the Nissan 350Z that needs some kind of modification either in allowing camber/castor settings or finding out if there is some other front end distortion that only Albert Einstein can determine.

 

my new set of michellins are feathering in the front.. im getting pissed, i only got like 5k miles on them

 

It's a sports car that comes from the factory with negative camber and sticky tires for performance reasons; this is going to cause early tire wear. Take a look at any sports car, they all burn through the insides of tires for the same reason. Yes driving style will also add to this but even if you drive like a grandma the insides of your tires are going to wear out quickly with negative camber and a tire with a tread wear rating of 140!

I agree that Infiniti should have made these cars with adjustable camber for people who could live with the degraded handling to get better tire wear. But they didn't so just go get a set of Kinetix front and rear camber kits for ~$800, set your camber to 0 degrees and go get some hard tires that will last longer. That is your only solution. If you can get Infiniti to pay for all/part of it, then more power to you.

 

you all just need to stick with driving a Honda Accord.

 

I also had major feathering issues at 7.5k miles. Ended up arguing with dealer, they flipped tires and realigned which I paid for. I registered complaint with Infiniti Canada and got nowhere.

 

Go to Http://nissantireproblems.com/ and file your complaint with a zillion other unhappy Nissan/Infiniti owners with tire wear issues. There is a special section just for the G35 Tire wear problems. Good luck and with enough complaints Infiniti actually might come out with a TSB and throw us a bone like a few free tires and an extra alignment on the arm.

 

So how much of a negative camber do the stock G35 have....... I'm more concerned with the front camber...... Is it around -1.0 or more?

 

I got 25K out of mine with NO feathering.

 

I realize this.......sorry for the missunderstanding but there are a lot of things that could cause feathering.

 

Thats about right I believe its -.92 or something

 

I hate stupid people. No **** you are going to have more wear on a tire on the inside when you have negative camber. Dont patronize me telling me I need to look up my facts. Who the hell are you. My mothere knows more about this car then your feable little mind and she thinks its a Lexus. Dont shout out general facts and say that I dont know crap.

 

Until this feathering issue gets closer to a resolve (probably never) I am getting my front tires rotated from side to side by dismounting, flipping, remounting, rebalancing and put on the opposite side of the front. BJs will do the entire operation for $9.00 per tire. How can I go wrong? In the meantime, I can get some additional life out my unidirectional Avons before they are feathered to death. My outside and middle treads are wearing perfectly even. I may have to do this process every 3,000 miles to keep the treads in check.

I agree. If you want a car that provides outstanding cornering, you've got to go with an agressive alignment and soft tires. There's no car that going to corner at .9G or better with tires that will last 40K miles.

I disagree with the comment about extending tire wear by grandma style driving. Gentle cornering could actually accelerate the uneven wear, since the idea of the negative camber is to give you the maximum tire patch when cornering at the limits. In other words hard cornering will shift the contact patch to the outside of the tire, which will help promote more even tire wear.

 

There are many 'sports cars" out there that handle as well or better than the G that do not prematurely wear the inside of their tires. Those manufacturers include Honda, Mazda, BMW to name a few. I love my G but am able to admit Nissan has a design deficiency when it comes to this suspension and the affect on some G's and Z's.

Tire life on some cars is vastly compromised because of this feathering. Most of the tire has many more miles left on it but the feathering on the insides creates additional road noise and forces early tire replacement.
