dont undertstand why my post was deleted?
so...
my z has stock premium wheels... the chrome wheels.
i believe the stock rear wheels are 8.5, correct me if i'm wrong.
Can i stretch fit 225/45/18 sized tires on there?
Any help would help.

 

stock rears are 245/45/18

 

I would go 215 mm.

 

Dude. It wasn't deleted. It was moved because you put it in the wrong section.

do you think they are premium because they are chrome?

 

It wasn't. You have two posts, this one and the other one you asked this question in previously:

I believe it'll work since I've even more drastic ones, but, why would you stretch the rear and not the front? But, I suppose that's for you to answer.
