I tried researching on this forum if that tire size is okay.. couldn't find much. So I asked around to some people I know who know quite a bit about cars they told me I'd be okay..
OCD,,,look in the door jamb & it will tell you what size came on the car...if it still has the factory wheels it came with.

Put these tires to the test today, since it was a warmer day out today I figured it'd be a good day for it.. anyway, car seems to have fast acceleration and also didn't have any traction lights come on, abs lights, etc. I think I'll just keep these on until I have to get new tires again and next time around I'll get a different set up. Maybe 255/40/19 front and 285/35/19 in the back

With your 245,275/40/19 setup; this may be the most diameter differential I've seen without causing the Christmas Tree effect.
Around a 3.5% difference @ right at a full inch taller in rear.
Is your Z a Sport with 9/10 stagger or 9.5/10.5 Nismo stagger?

Yes I'm running different tires front and rear right now. It is the height you need to watch for not the width.

With that inch taller rear tire remember you are effectively changing your rear end ratio, which is a torque multiplier. Your speedometer will also be off now, as will the mileage you are putting on your odometer.

Yeah I know, that's why I'm not a huge fan of this set up. Like I said before it just sucks the previous owner had these tires on in the first place. That's why when I get some money saved up I'm just gonna get some nice summer tires for spring and summer and I'll just keep this all season set up for winter only when it's only used for a little bit.

RE-11, 245s up front 285s in the rear. Great summer tire setup that will get you a lot of miles. (40k on my last set) It does not get cold enough to be an issue here but I wouldn't leave them on (or any max performance summer tire) in the winter in Nebraska.

I'll look into those tires. My plan is to get new summer tires and new black aftermarket wheels when I get my tax return.. I am pretty excited for it! And since I live in the Nebraska my plan is for when the winter comes around I'll just put these pirelli all seasons on and swap them every winter/spring.

Putting my odometer to the test. I went to the gym this morning and looked up the miles to the gym and my odometer was right on the money. It's GTG so far. I'll keep doing tests on it
