Hey, Does Anyone Have Staggered Rims On Their X? whts the widest tire you can get on an x? the guy at UT told me a 245 was as wide as i should go but i would like to get a 275 on here.........any one have pics or opinions?

 

Only thing that comes to mind is if the front upright is any thicker, otherwise your limitation's would be the same as on any RWD sedan. You can run 255's in the front with 8.5" wide rim with a 38mm offset. And up to 275's in the rear on a 9.5" wide rim with a offset ranging from 45mm to 55mm.

I just did a fitment test where I removed a front shock/spring and mounted one of my 255 rear tires on the front. I don't see any reason that a 265 can't be run on the front of the sedan, except that the tire will start to go out past the fender wheel well, it would start to stick out about half way down the fender opening. Kinda hard to explain.

I would not run anything narrower then a 245 tire in the front if your going to the expense of buying rims and tires. Can't say I'm a fan of staggered setup's either, but some do like the look of such setups.

 

I dont think you can go staggered on the X without messing up your AWD system. Basically the fronts and rears will be running at different rpms. The AWD system would compensate somehow but I would think it would cause some long-term damage? My $0.02.

I'm getting 245s put on tomorrow all around. Will post.

 

yeah, my dad has a cayenne turbo w/ 21s that are staggered, and he has a 911 Turbo w/ 19s that are staggered, both are AWD and he has no problems, whats the diffrence? i would like to get a 19x8 or 8.5 for the front and a 19x9.5 in the back........it just doesnt make sence that if other AWD cars can have staggered rms why can a G35 AWD?

 

The OEM Porsche setup is staggered.
The difference is that the Porsche logic algorithm was developed
for a staggered setup & the G35x was not.

I have had other (non-staggered) AWD such as Audi & was told by a tech that I could
damage the AWD system.

 

so no one has staggered rims on their x? i thought that if the overall diameter of all the wheels was the same then they would all be going the same rpm right?

 

Finding such a close match in diameter may not be good enough. Depending on the type of center diff, it will either wear/overheat the diff, or cause the tires to wear excessively. Not to mention, it could potentially cause a dangerous situation. AWD OEM staggered set-ups will likely be part-time AWD or be geared correctly on each end to match the tires being used.

 

It also has a lot to do with the AWD/4WD technology. Like what kind of transfer case: Is it fluidic, mechanical, etc. What kind of fluidic mechanism? etc...

Running on a staggered setup on an AWD system that was not designed for it will result in:

Best Case scenario: Nothing
Medium Case: Overheating of the transfer case, leading to future failure.
Worst Case: Complete Failure, resulting in/from shattered gears/teeth/etc, resulting in lockup, possibly causing loss of control and/or a crash.

 

so no one in the world has put staggered rims on their G35x??????

 

I too would like to find out, as I was planning to get a staggered setup on my X as well. I had ask the same question before and someone on this board said it would be fine.

 

i would like to go 275 rear 245 front on my x, and i dont see why i cant.

 

thats exactyl the setup i want, but it cant be done from what ive been told.....Mike At UT said you cant........

 

I think someone needs to explain this a little more, from my humble understanding the AWD system in the X is normally 100% rear drive anyway right? And it only kicks in and variably redistributes torque between front and back when there is slip. Is it also safe to assume that the VDC programming between the RWD and AWD is the same? So how exactly is a staggered setup bad? Considering the staggered setup would only be spring/summer maybe fall applications and in the winter and snowy conditions it would be back to the non staggered OEM wheels with snow tires. I would appreciate if someone with better knowledge on the ATTESSA-ETS AWD system can provide a better (more technical?) answer as to why / why not. Also don't folks with GTR's run staggered setups, how much of a difference is their ATTESSA-ETS Pro version different from ours?

 

i agree with you, it just doesnt make sence to me why you cant stagger them if the rolling circumfrence is the same........

 

Ok for those still interested, I've just confirmed with the GTR folks on Freshalloy, staggered width rims won't be an issue with Attesa e-ts, as long as the the wheel+tire diameters are the same front and back... woo hoo.
