I am planning to pick up some Five:AD S5:F with these specs below:

FRONT 19" x 8.5 Offset +20 PCD 5x4.5
REAR 19" x 9.5 Offset +25 PCD 5x4.5

Do I have it correct?....And will these work with these tires?

FRONT 245/35/19
REAR 275/35/19

***Note: I do NOT plan to lower my Z at all... will this look ok?
or should i go with another tire specs?

'Newbie here...so any info/suggestion would be great! thanks!!

 

I could be wrong, but you will have a hard time installing them on a Z with that lug patern.
Don't they offer a 10.5? If so i would throw 10.5 in the rear and 9.5 for the front.

Edit, i looked and yes they offer 10.5 rears, and BTW the tire sizes you selected are perfect, same height as stock tires just wider.

 

^+1... you mean 5x114.3 PCD right? 35's may look too skinny for a 19 though w/o being lowered.. i'm not 100% sure.

 

5x4.5 = 5x114.3 just different units of measurement.

 

370Z tires are:

Bridgestone Potenza RE050A, 245/40R19 / 275 /35R19

So you will be running the same size except front 35 instead of 40 series. This will be perfect.

 

All looks good.

4.5 * 25/4 = 114.3.
I agree about the 9.5 front and 10.5 rear, if at all feasible and if it makes the wheel look "better".

 

Everything looks good except wheel (rim) widths, so change to this:

9.5" fronts
10.5" rears

Try to keep the offsets for both around et.20.

 

Gotcha.. thanks

 

wait... so if i run 9.5 in front and.....10.5 in the back....what tire sizes would be correct?...and ideal offset?

 

255/35 and 285/35 and a low +20's offset will be good.

 

edit: ^beats me

245/35 front and 275/35 rear

or

255/35 front and 285/35 rear (more sidewall = more circumference)

ideal offsets would be around 20mm for normal flush look on 9.5" and 10.5"

 

ok...thanks for all the info guys!
