Default Infiniti G37 owners....tire wear question.....

Figured I'd get more traffic here than in Other Cars......I have a 2010 G37S Sedan and just rolled over 13K miles. While changing the oil this weekend I was checking the tires and I noticed that all 4 are wearing pretty much the same, the outsides have worn down about twice as fast at the insides on all 4 tires. Those that have the Ss know that you can't rotate the tires do do the tire design and size differences with the fronts/rears, similar to our Vettes.

Has anyone with a G37 noticed similar tire wear on their OEM tires?? No feathering or such, just a more worn tires on the outside on all 4 corners. If I could I'd remount the tires on the other wheels for the other side but just can't do that either, the outside MUST stay on the outside.

currently have an 04' coupe and did have an 08' sedan... the 08' never had any problems and my 04' has ridiculous camber (on purpose) so obviously it wears on the inside but it's supposed to...

obvious answer is to get the alignment checked as well as the camber/toe... dealer should do this free if everything is stock and you've got warranty.

Common problem with the G series cars.

Factory set up towards handling.

The front end does not allow for camber adjustments needed for proper wear.

Well, that's a heck of a way to put a major car line into production.

Where's the OP? Probably out enjoying his Infiniti.

You can't rotate by dismounted and moving side-side?

Anyhow, go over to G35Driver and ask there.

That's my thoughts. I put Z06 alignment specs on my 2000 C5 and my rears wear more on the insides by design, but the fact that all 4 of the G37s tires are wearing more on the OUTSIDE is just plain baffling. I do drive kinda zippy, even in the G37, but nowhere near hard enough to warrant such accelerated tire wear on the outside of the tires. And it's so uniform across all 4 tires it makes me think the car is dialed for that sort of wear. Guess I'll need to join up at the G35/37 forum and ask the peeps there. Thanks guys!

I had an 07 G35 coupe and didn't even get 19k out of the factory Bridgestones. Like you I couldn't rotate them. I had the sport suspension and I think they are sticky, soft tires for handling. But I had hoped for many more miles than that before they wore out.

I had an '05 G35 Coupe with the Sport package. I got about 22k miles on my stock tires.

The G35 Coupe is based on the 350 Z. Nissan had a lot of problems with tire related wear on the 03 and 04 models, to the point where there was a class action suit against them. The tires would scuff and the noise after a while was unbearable, not to mention the loss of tread. Their response was to alter the wheel alignment and give customers a new set of tires. From my time on the Z forums it appears that the suspension geometry on those models was the real cause but it would have cost a fortune for Nissan to replace the front suspension on all their Z models. Subsequent years were better but I've never heard of anyone getting a lot of mileage out of their front tires. On the plus side my Z was the best handling car I've ever owned and was the easiest to drive. The handling was telepathic!

If I were you I'd get in touch with Infinity to see if there are any service bulletins or at least get their recommendation on alignment specs.

My sons 05 had the problem. His wore on the inside, and the best camber he could get was around -0.8. Tires seem to be doing better now.

He went to a stiffer spring to raise the front end up a tad to get the front camber to -0.8, it was well above -1.0 before.

I misread the the OP's problem, thinking it was same as my sons G35.

Nooooo

No car and/or suspension setup is supposed to wear tires unevenly. The kind wear you're talking about is more about a mismatching of suspension setups to driving style.

Driving aggressively on a conservative setup will typically give you outside wear likely indicating a need for more negative camber among other things. And vice versa driving conservatively on an aggressive setup will often yield inside wear.

Again, this is not how things are ever "supposed to" be. It is just how things will be if you don't setup your suspension to match your driving conditions and habits.

Yup not a lot you could do with the stock suspension to adjust, that was one issue. It was more prevalent on the Z's than on the G's.

I also think another issue is the cars tended to bring in a lot of people who were not used to higher performance cars, so there were tons of complaints about noisy brakes, brake dust, etc.

I know what you are saying BUT if I have more negative camber dialed in on my C5 and it's lowered a bit it does wear the inside rears more. I obviously can't drive it like I'm on a track when I'm on the street. Not excessive wear on the inside but when I'm to the wear indicators on the outside, the insides are smooth.

Perhaps the stock settings on my G37S is such that it wears the outsides more cause of more aggressive driving but it's not like the car is getting track-type cornering when I'm driving it, just seems excessive based on my driving style and that the car is only a year old.

Bummer that it appears that you can't adjust the stock suspension very much to help dial in some more negative camber and balance that out. Maybe the sport suspension allows more adjustment then the stock suspension. Really need to ask the G35/37 peeps in their forum...eventually.

08 G37 coupe, tires replaced at about 30k. Now have about 8k on PZero's and still look good.
Earlier G35's had problems, but I never heard of 7's having any problems.

I forgot about the brake dust. My Z was the absolute worst car on the planet for brake dust. It was so bad I actually changed pads at about 10K miles. I couldn't put up with it any longer. The pads I put on made no dust and stopped just as well as the stock ones. Other than the brake dust issue and tire wear it was a great car.
