My friend has a '04 G35x and wants to buy 350Z wheels. The wheels are 18x8 in the front and 18x8.5 in the rear. These wheels however have the same size tires all around; 225/45-18.

Will installing these wheels cause any driveability or AWD reliability issues? Any other problems this setup can cause?

If running these wheels is safe, should he run the 8.5'' in the front and 8'' in the rear or vice versa & why?

Thanks

 

should be fine, run the 8.5" in the rear and don't rotate. Running a wider wheel in the front would just be a bad idea, and can lead to instability at speed in corners and/or unpredictable steering

 

My understanding is the variance in tire height between the two aspect ratio, front to rear. For example 26.2 in front and 27.2 in rear.

Typically a 2wd sedan would run 8.5 in the front and 9.5 in the rear. It's in the faq... or some other faq :-)

 

As long as you're running the same size tires all around, you should be just fine.

 

I'm thinking about doing the same thing.
But running the same size tire all around should actually make your front tires taller, but I don't know how much taller....I assume very little.

Although it might look goofy...

 

Out of curiosity...
I thought the G35X is Attesa-etc 4WD instead of AWD.
Which runs RWD most of the time but front will have power when lose of traction at the rear.
A lot of Skyline GT-Rs run stagger tires so i thought G35X are fine with stagger set up.

 

I thought 4WD is four wheels driving, all-time, split, and is selectable. AWD splits power as needed. I'm pretty sure being staggered will effect the system. It really doesn't kick in often, but I'm not sure I'd risk it regardless.

I'm also looking for new wheels and having to opt out of staggered ones is a major PITA...

 

4WD is spilts power as needed and AWD is all time 4WD

ATTESA-ETS is 4WD

So is it just people just normally think staggered is bad for G35X based on they think G35X is AWD?
All the GT-Rs are 4WD and many of them run staggered set up.
R35 GT-R comes with staggered set up stock.
