G35XS-Can I run Staggered Wheels/Tires?

[harleydav88]

Hi. I am thinking of purchasing a set of Staggered 19" OEMs (Enkeis) thatwould came on a G35/G37 Coupe for my 2008 G35XS Sedan.When my tires go, I will put snows on my 18" NON STAGGEREDrims for the Winter, and use the 19's for the Summer.

Does anyone think this is a problem? Should I not run Staggered on an All Wheel Drive?

Lastly, the Car will look hot right? I am pretty conservative, and full chrome or anything DUBBED up would notfit with me.

Thanks for the Advice.

You can run a Staggered setup on an AWD car.I know this because I do on my AWD.

The important thing with AWD is to keep the total diameter (rims + tires) of the fronts and rears as close as possible to each other.

This tire size calculator should help...http://www.miata.net/garage/tirecalcold.html

I think you need to ask one of the techs about that...

I think the AWD system could get messed up by running a staggered up!

As riceqx2 stated, you'll be fine as long as you keep the overall tire diameter the same, front and rear.

I stand corrected and I assure you that I was wrong as Jerome knows his stuff!

Hahaha. Yeah. Whenever I make a post, I'm always 100% certain of the answer. Whenver I'm unsure, I say so.

My understanding is that if you stay within something like 3% difference (the closer the better) that you will be ok with the AWD system itself.

However before you go this route it seems to me that there may be an issue with the VDC so you may want to check into this with an Infiniti tech.

VDC is based on the rotation rate of the wheels compared to each other. Therefore, if you have the same tire diameter all around, VDC will not be affected. You could run a 2" wide wheel in the front and a 10" in the rear (extreme example). The only thing that the car "sees" is how many times each one rotates compared to the others.

You'll be fine.

VDC= Vehical Dynamic Control.

A sudden change in surface consistency can affect your car's stability during evasive driving. Vehicle Dynamic Control* uses various sensors to help determine your steered path and keep you in control. If your vehicle begins to understeer (plow forward) or oversteer (fishtail), VDC applies appropriate brake pressure to individual wheels and/or reduces engine output to help keep your vehicle on its steered path.

*Infiniti VDC system is designed to help improve driving stability, but does not prevent accidents due to abrupt steering or by careless or dangerous driving techniques. Always drive safely. (Infiniti site)

If I remember the full write up on this it involves more than just looking at rotation.

VDC does far more than just measuring wheel rotation. Besides wheel rotation it also meansures steering angle and involves accelerometers in helping determine actual vehicle position in relation to intended vehicle direction.

I have a 2008 Sedan, the following is from the 2007 ESM:

2007

System Description

• Vehicle Dynamics Control system detects driver′s steering operation amount and brake pedal travel fromsteering angle sensor and pressure sensor. Using information from yaw rate/side G sensor and wheel sensor,VDC judges driving condition (conditions of under steer and over steer) to improve vehicle driving stabilityby controlling brake application to 4 wheels and engine output.• During VDC operation, it informs driver of system operation by flashing SLIP indicator lamp.• Electrical system diagnosis by CONSULT-III is available.

I believe you have a 2005, the following is from the 2005 ESM:

2005

VDC Function

1. In addition to TCS/ABS function, VDC detects driver's steering operation amount and brake pedal travelfrom steering angle sensor and pressure sensor. Using information from yaw rate/side G sensor andwheel sensor, VDC judges driving condition (conditions of under steer and over steer) to improve stabilityby controlling brake application to 4 wheels and engine output.2. SLIP indicator lamp flashes to inform driver of VDC operation.3. During VDC operation, body and brake pedal lightly vibrate and mechanical sounds may be heard. This isnormal.4. If vehicle is rotated on turn table, or rolled and rocked on ship, ABS warning lamp, VDC OFF indicatorlamp, and SLIP indicator lamp may turn on. In this case, start engine on normal road again. If ABS warninglamp, VDC OFF indicator lamp, and SLIP indicator lamp turn off after restart, it is normal.5. When driving in steep slope such as bank, ABS warning lamp, VDC OFF indicator lamp, and SLIP indicatorlamp may turn on. In this case, start engine on normal road again. If ABS warning lamp, VDC OFF indicatorlamp, and SLIP indicator lamp turn off after restart, it is normal.

Therefore I believe it would be wise to consult Infiniti before making changes of this nature.

Ok. My bad. It does do more than look at wheel rotation, in all. It does have accelerometers.

Regardless, the vehicle can not tell AT ALL that you're running staggered wheels. My point still remains valid that if you keep the same overall tire diameter, the vehicle will not sense a difference...

No need to argue. It will work.

[adren77]

You can run staggered wheels...

You must have identical tires on all 4 corners (identical outer diameters to be more exact). If you get 4 same tires you will have no problems.

You wont be able to rotate your wheels so your tires wont last as long.

No need to argue. It will work.

If you change the lateral acceleration of the vehicle it can tell. In fact Infiniti states so:

2007:

If steering angle sensor, steering system parts, suspension system parts, ABS actuator and electric unit (controlunit) or tires have been replaced, or if wheel alignment has been adjusted, be sure to adjust neutral positionof steering angle sensor before driving.

2005:

If the following components are replaced with non-genuine components or converted, VDC OFF indicatorlamp and SLIP indicator lamp may turn on or the VDC system may not operate properly. Componentsrelated to suspension (shock absorber, strut, spring, bush, etc.), Tires, wheels (exclude specified size),components related to brake (pad, rotor, caliper, etc.), Components related to engine (Muffler, ECM, etc.),Components related to body reinforcement (roll bar, Tower bar, etc.).

Note the statement for the 2005 (exclude specified size).

Whether it gives a negative effect, it appears it CAN affect it. On other forums there are statements to the effect that it may cause the VDC to activated earlier.

So again I would consult Infiniti before stating that it will not affect the VDC when Infiniti appears to state otherwise.

For those interested in what can occur with changes such as these look for 'scrub radius'.
