I know a staggered tire set up is not good for the AWD system. i will be swapping out my fronts soon. Question is if I run staggered for a short period of time (< 1 month), should that be ok?

Also, would 245/45/18 or 225/45/18's be better for the G35x?

 

your vdc may be off for a month but i wouldnt worry if its only a month.

 

staggered rims on an awd car are fine as long as you run the same tire diameter on all 4 wheels.

 

i picked up 19x8.5 for the front and 19x9.5 for the rears for my car and am going to run 245 35 19s.

 

Why does this question need to be answered so often?

The width of the wheels do not matter, it's the total diameter that throws of the VDC.

This is in the sticky.

 

225/45/18 = 25.972" diam
245/45/18 = 26.681" daim

fronts approx 2.85% smaller (diam) than rear. Dont know if the G35x AWD system has a threshold regarding tire size differentials.

 

I AM referring to tire diameter, not width of tire nor rim.

 

no offense but why did you assume the diameters were the same... OP did post the two tire size options he was going with( one is stock front size and the other is stock rear size) which have different rolling diameters(sounds like he picked up coupe wheels-edit:he did, its in his sig.)


I really think your only issue will be that the speedometer will be off by about 1 mph. And make sure watever tire size you run, its close to your OEM g35x wheel's overall rolling diameter.

 

stocks were 215/55/17 = 26.311" rolling diameter.

w/i .4" on each new tire rolling diameter.

 

I will post this again and most likely again. I am running a 225/40/19 and 255/35/19 with no problems. I got a flat going to cali and ran a 225/50/17 on front and still had no problem. Keep the diameter close.

 

I misread your post originally, but what I said stands. I believe this information is also in the sticky. I'm going to check now...

You can run a 3% (max, it might be 4% or 5% though...) diameter difference before the VDC will notice anything at all.


EDIT It's not in the sticky, does someone want to verify the percentage and I'll PM Tim to add it?

 

^^^3% is maximum you want it to be off by so speedometer will be off by less than 1 mph when it reads 60 mph on the cluster.

OP- go with 225/45/18-its larger by a difference of 0.47 from your OEM specs.

245/45/18 is larger by 3.12% in its rolling diameter

that would be great.

 

245/40/19 all around on mine with Staggered coupe wheels. No issues. Like everyone else said, try to keep OD the same and youll be fine.

 

235/45/18
265/40/18


I run/ran on my X no problems.
