Hi,

Long story short, my rear stock summers wore out crazy fast (10,000 miles). The inside of both rear tires was warn almost to the metal while the center and outside was fine. So I went to the dealer and had the car aligned (my G37S coupe is stock - suspension not modified)

I have the results from the alignment before and after. Toe was OK except for one wheel which was way out, but both rear wheels had a negative camber of 2.5 deg, which I assume is the reason why the inside of my tires was worn. After the alignment, I am surprised to still have a negative camber on 1.3 deg on both rears.

So my questions are:

- What are the specs for toe and camber? I can't find them in the manual. Is a -1.3 camber normal?
- Can normal driving cause the camber to change that much? How often should you check the alignment?

I've never had such a tire wear issue on other cars, but this is my first rear wheel since my beloved Chevette in the 80's and 400$ a tire, I'd like to keep this set a little longer

Thanks,

Steve

 

Camber will wear tires rather quickly, but toe will absolutely chew through them. How would you describe your driving habits? If you like to drive relatively hard, then a little bit of toe in the rear will go a long way.

The 2.5 camber is higher than stock spec. Are you lowered?

 

The nominal setting for the rear camber is -1.33 degrees with max at -1.83 and min at -0.83 so you are right on the money. The specs are on page RSU-27 in the FSM.

 

Dropped on Eibachs with SPC rear camber kit. Could use a front but it's close and tire wear is normal.

 

My car is not lowered and I drive like granpa Seriously, I don't drive that car real hard and TC is on 99% of the time.

Glad to know that after 1.3 deg camber is normal...

I still don't get it. What caused your camber to be so off??

 

I would suspect that lowering the car + getting the camber kit, without immediately getting an alignment afterwards caused the extreme tire wear.

 

toe is more important than camber for uneven tire wear. i run -1.0 front, -1.7 rear camber but with 0 toe all around. just get your toe to 0 and you'll be fine.

 

He is stock suspension per several of his posts.

 

oops I thought the post above was the OP.

Could it be that he hit some potholes too hard? Regardless, an alignment should help with tire wear. 0 toe as suggested above will add tire life.

 

How much do alignments at the dealer go for? I gotta get mine done.

 

We have horrible roads up here, so it's the stock answer from dealers with regards to alignment... Still, I find it hard to believe that the camber could have been so off, just by hitting potholes.

Alignment was 110$

Somewhat related question - Now that I have new tires and an aligned car, I had a feel at the temperature of the tires after a 30 minute (easy) drive. The inside is significantly warmer than the outside, at least 15F I would guess. What would be a normal temperature gradient between inside/outside of the tire?

110 is average price.
