Sorry, I did an extensive search but couldnt find the exact answers to my questions:

I have a 2008 G35xS. After getting an oil change at my dealer, the invoice had "tire inspection" as one of the charges. I assumed this didn't include a tire rotation, so had my local mechanic rotate my tires (I have +11k miles).

He rotated them front to back because he noted that the tires up front were slightly more worn than the ones in back, but not side to side.

My questions are:

- Can you rotate G35xS tires front to back AND side to side, or only the former?

- Do the front tires of the X typically wear more quickly than the rear? I ask because I'm not positive if my dealer rotated my tires or not. My worry is the rears were more worn than the fronts and the dealer already rotated them and my mechanic just switched them back...

Thanks in advance!

** Note that the more worn tires had the wear closer to the sidewall of the tire (and I dont drive aggressively - no peel outs, etc.)

 

This should help.

About the wear on the X. It depends from the driver. If you push your car in the corners on the X it will use more tires on the front. If you just like to go fast in straight the rears will worn faster. If you don't push your car and the outside wear faster than you might have some alignment issues. It is hard to tell when the X is going to fast. Sometimes you don't feel it is fast but the tires are spinning.

 

why wud you do that anyway . . .
G's tyres are not typical and are different in size .
front size differes than the rears . .
i believe rotations wud harm your tyres .

 

The xS uses the same size tires all around. They aren't staggered. Anyway, my rears have always worn faster than the fronts. I'm a non-X, though.

Also, your stock tires are Dunlop Sport Maxx A1? I'm pretty sure they can rotated every which way.

 

My rears wear slighty faster than my fronts. Rotate them often. You want to keep them all as close to the same outer diameter as possible or it can have negative long term effects on the AWD system. Mine usually get rotated when I switch from my winter setup and at some point through the summer. I do it myself.
TIP - get yourself a tire tread gauge. They only cost a few bucks.

 

u r wrung and ignant

 

haha thx everyone for your input. So from what I can gather, it looks like I can put any tire on any side, and should rotate back left to front right, and back right to front left.

 

ignant ?!!
what r u tryin 2 say ?

 

So you're saying when you went to the mechanic after the dealership, the fronts were more worn? If so this means the dealership rotated your tires, most of the time the X uses only the rear wheels when driving. If your mechanic switched the more worn out tires to the rear, he pretty much just switched them back. And I don't understand why he would do this being that your tires would last longer in the front.

edit: and yes the xS is non staggered

 

I have a 2008 G35xS and have rotated the tires every 5,000 miles using a rearward cross and that has worked well. One alignment at 15K just for good measure. The Dunlops have worn well, I feel. They'll make it to 25K miles with roughly 3/32nds-4/32nds left. Not enough tread depth for Western NY in winter, however, so some Hankook Ventus V4s are being ordered up (I was tempted by the Kumho Ecsta LX - a friend has them on his G in 17's and they are great - but the Hankook is more performance-oriented and has gotten good reviews). The V4 is a directional tire, unlike the Dunlops, so back to a front/rear pattern. The key is rotating at the VERY least every 7,500 miles...but 5-6K is better.

 

The tires wear faster on the outsides of the fronts. The X has a front weight bias and this goes exponential when cornering.

 

OK so I confirmed w/ my dealer - "tire inspection" on the invoice does NOT indicate tire rotation, they were only inspected. So the front tires did wear a little more than the rears on my G35x probably due to what Liquid Gx suggested.

One last question - does it matter as much if I do (or don't) rotate the tires laterally? I only swapped front to back, but not left to right.

 

If your tires are not uni-directional, you should be bringing the fronts to the back (same side) and the backs to the front, crossing sides.
If your tires are uni-directional, you can only go front to back.

If you tires are staggered, you do not rotate them.

 

Aren't the stock Dunlops that come with the Xs unidirectional? Mine have a big directional arrow on the sidewall showing the direction of rotation. I have only rotated mine front to back, no side to side.

I have shown more wear in the front than the rear, particularly on the outside edge.
