So it's time to get winter tires for my G, and this is the first winter that I've gone through with this car so I was wondering if a set of 16s would fit. Thanks guys. (Right the front tires are 225/45ZR18, back are 245/45ZR18)

Sure it will fit but you don't some oem wheels to rock?

Dayum 16's?? Are you talking about fitting them inside the trunk? You can fit like 6 maybe. Dont do 16's as you will prob lose control in the snow or something, and having such a small diameter wheel and having 240ftlbs on a heavy azz car. Find some oem 17's or cheap aftermarket 17's somewhere.

is this a trick question?

16" wheels don't affect the diameter! you'll be ok. Narrower tires offer MUCH better winter grip on ice and snow. Now finding a set of stagger fit 16" winter tires is gonna suck, so he is right in advising you to look for a cheap set of 17's.

i believe the base model 2002 skyline comes with cloth interior, no radio controlls & OEM 16's so you should be fine.

They fit on non brembo. I used 16" steelies with 205-65-16 in winter-they rocked, sliced through deep snow like a knife.
