Hi
I have a question about 19" rim.
will 19x9.5+29 front and 19x10+10 rear fit a 2004 350z?
Thanks.

 

yes.

 

and usually i notice that people use 19x9.5 and 19x10.5.
will it be weird for 19x9.5 and 19x10?

actually how to calculate the width if i want the wheel to stop at around the fender, but not outside the fender?

 

Use a offset calculator to compare your current wheels to the new wheels. With the new dimensions, check the car with a tape. Do you clear the suspension, brakes calipers and fenders? Reference: http://www.1010tires.com/WheelOffsetCalculator.asp

 

for front wheel,
if I compare original stock setting 18x8+30 to 19x9.5+29
inner clearance is 18mm less (the inside of the wheel to the strut housing)
would that be a problem?

I might have a 5mm spacer.

 

+10 is a very aggressive offset so a spacer on your front wheels would help with your front looking slightly tucked.

 

Not at all. Maintain a 20 mm difference in tires and you will be fine.

 

thank you all for help

 

I realize that people use 20-30mm larger rear tires.
it stabilizes the car better?

 

No. A 20 mm difference will maintain the proper tire circumference. This will make VDC happy.

 

As a reference, 255/35/19 front and 285/35/19 rears get you pretty close to OEM tire outer diameter to keep vehicle dynamic system (and wheel gap) happy. And it just so works out that there is a 30mm width difference between front and back.

 

icic. thanks.

 

I would do a 10mm spacer in the front to even out the offset from front to rear.

 

What is the bolt pattern, and what size tires do you plan to buy for them?
