My 04.5 G35 coupe has 11,000 miles and I have noticed that my tires have been making alot of noise and the drive feels weird. So I take my G in and they say my tires are wearing out unevenly and they want to charge me $1200 to replace all 4 tires. I never burn out on these tires and its weird that the tires are wearing out so soon. I know they have the feathering problem on the Z. Is there something I can do? Please help me

Thanks in advance

 

Get the new tires and make sure that you get an alignment and get the new tires weighted properly.

 

yup.
I had same issue, tires worn uneven..My insides were worn, the outsides were OK. The center stripes were down to the wear marks (OEM Michelin 225/45, 245/45). At 15000 miles.

I bought some Michelins from tirerack.com..even with shipping it was cheaper than anything in town.
I took them to a tire store, had 'em mounted, balanced, and aligned..done.

Tires are important..I respect tires....and brakes..

 

Get a good lawyer. I had the same issue on my previously owned 350z and through raising enough hell managed to get them to buy the car back. It's rather ridiculous that the G35 has the same issue yet Nissan won't recognize it like they do on the Z. I actually had my tires replaced twice and cross rotated once all under warranty when I owned the Z. Good luck.

Is it just the rear tires? or all four? I would speak to the dealership about it. Have them check the alignment.

 

My brother's coupe has exactly the same issue, and now needs new tires once again after ruining the OEM's and then the second set. The alignment was checked twice and found to be fine, and neither set of tires was abused in any way.
The first set of tires lasted about 20k miles, the second about 10k miles so it's getting worse, and it's not the alignment or tires pressures that the dealer and Nissan will lead you to believe.
The dealer would do nothing for my bro because Nissan will not step up with warranty like they did with the 350Z, and no amount of complaining has done any good. They say there have been few complaints.

He's considering selling the Coupe out of disgust and not buying another Nissan product of any kind. He's really pissed, as you can imagine.

It's obvious that there's an issue in the front end of the Coupe, but they'll do nothing to help.

Oh, and we live in Southern Ontario, Canada. I don't know if anybody has gotten any help in the U.S.-- I seriously doubt it.

You probably need $1200 to replace your rubber every year if you don't change your driving habbit. I still have my original rubber on 18000 mile and they look fine. Drive safely at race track not on the street.

 

this happens on 350z's all the time. nissan replaced tires and realigned cars that were affected - even extended that coverage again to oct 31st this year for 2003 models whose warranties were already up.

 

Yes, but I wish they'd step up for Infiniti owners too. So far Nissan/Infiniti has not acknowledged that there's anything wrong at all with any of the complaints they've received on the Coupes.


ChewChew_G, I see you answered both threads the same way, so I'll direct you to my previous answer instead of rewriting it.
Here's the link:

...and are you in Canada or U.S.?

Ditto on the problem. Mine has been properly aligned and has the inside feathering. The tires are not worn out but dramatically shortened the life of the OE ones plus I had to pay to have them flipped and scratch 3 of them. Dealer or Infiniti won't step up. It has been an exasperating experience to date and I am not through yet.

 

What I find strange; is that no one has clearly defined what is causing the problem.

Since sedans, coupes & 350Z all have the same basic suspension components...
It clearly seems to be related to suspension height.

.. sedan ~ haven't heard of any problem
.. coupe ~ some problems (1/2" lower than sedan)
.. 350Z ~ big problem (1" lower than sedan)

Is it related to the geometry of the lowered suspension?? (not just alignment)
For example the angle of the lower control arm changes.......

I'm certainly no expert;... I just don't understand why this problem hasn't been figured out

 

I have to agree Ian. Why? When you speak to Infiniti they have a canned spiel about the bad roads, getting alignments and all kinds of other nonsense...essentially everything to get them off the hook.

They are also very defensive when I mentioned the 350Z issues and claim it is an entirely different car with issues that have been corrected and there are no related issues with the G.


Update:
Just spoke to my dealer service manager. I am heading in to see him in person sometime next week. He was very attentive and knows there is an issue with the G feathering as there was with the 350Z. He has spoken to head office but has been told basically to service cars and that he is not an engineer. He said alignments concentrating on the toe (which he felt caused my feathering) should be done at least every 6k on these cars since the tolerances for this "race car" are so close. Not too hopeful there is much to be gained from meeting with him but I just have to go through the process before I fill out my most recent customer service dealer satisfaction survey from Infiniti.

Yes Ian, to me it's obvious Nissan/Infiniti is trying to snow us, since we know the suspensions are basicly the same..- and yes the Sedan probably wont have any issues due to a less aggressive/sporty alignment spec.
They just don't want to step up for so few (so far) Infiniti owners.

There's no doubt the alignment settings are very aggressive for the Coupe, and that will worsen the issue but shouldn't cause such excessive and premature wear.
When my brother bought the second set of tires from Jerry at Infiniti of Yorkville, Jerry expressed concerns over the "compression rods" on the Coupe and that they were probably the culprit.(no he didn't look at the suspension)

I'd bet that the people in the know at Nissan are very familiar with the issue but are hesitant to even admit any knowledge of it for fear of liability claims.
(check out what Nissan told Deane's service rep. on the subject.......With that kind of Draconian attitude, there's not much hope of getting any help unless many more Coupe owners have the same issue and complain long and loud.------- Then something might be done such as with the Z owners.

For now tho, the prospect of buying a new set of tires every summer isn't sitting to well with Terry.

Thanks for the thoughts, tho. One can only hope that Nissan is paying some attention.
I'd like to think that they're interested in keeping customers with decent service as well as a decent product. -- If one of those necessities is missing, in my humble opinion "you ain't got diddly".

Hi Deane, true the tollerances are tight for the Coupe as well as aggressive and would have a big bareing on tire ware, but Terry's alignement on his Coupe was checked after the first replacement tires were installed , and now after 10k miles (15k kilometers) the alignment check reveals that it is 'spot on'--------absolutely no changes required!

Terry has complained to Nissan/Infiniti, and pressured the dealer to contact Nissan tech....... all to no avail.

They're just not going to bat for so few....and they don't want to spend millions again as in the Z fiasco, so they're backing right away...
That's a pity.....because they'll find customers will 'back right away' too.

G/L with the service manager next week. It very much sounds like his hands are tied too, but let's hear what he says anyway.
-- I wonder if he can find out how widespread this issue is? It would be nice to know nationally how many owners/rides are involved at this time.

Folks,
What you think good or bad tire wear is worth knowing I think. 18000 kms (11K miles) if I understand "1985" correctly is what he has driven in his 280 hp, 3400 lb sports car with tires with a 220 wear rating and maximum performance designation. highway miles, or lots of launches from light to light? If the tires have worns substantially more in the centre, that's overinflation. Were the pressures checked every two weeks? PV=nRT- it's the only thing I remembered from Thermodynamics classes. Summer heat equals overinflation.
I kept my inflation checked, drove spirited in the city and on the highway, and replaced my rear michelins on my 03 after 18K kms. I did, since I know how pricey these bad boys are, have the dealer check wear and include the report of wear on my invoice every 6K. And I noted that wear and traction were better at 34 psi vice 35.
But so you know, Acura, Mazda, Porsche, and BMW have all, in the past, had to tell customers to go pound sand, when it comes to tire wear with sports cars. I'm doubtful there's any solice in my comment, but you're not alone. I'm expecting to replace my 140 treadwear RE050s even sooner, regrettably. But it won't stop me from enjoying what is a great car. btw, no scalloping/feathering to report as yet in 2 g coupes totally 50K kms.

Cheers,
D
