Needed some advice on my situation:

Currently looking at a really good deal consisting of 4 Vertini Drift rims, but thing is they are all the same size at 19x9.5. I noticed almost everyone in this thread has there rear rims bigger at 10.5+. Are there any drawbacks for putting on all of the same size rim other than the deeper/concave look on the rears?

For tires I was then going to put 245/45/R19 on the front and 285/45/R19 in the rears.

Not sure if I need spacers or not to make the wheels flush with the car.

Does my plan make sense? Could I do 295s on the rears as well?

Thanks everyone!

I think the most important point to address is your tire sizes. a 45 series front and rear would make your wheel/tire diameters huge; particularly in the rear. If those are the tire widths you want I would suggest going with the stock sizes of 245/40r19 in FR and 275/35r19 (i.e. stock sizes for Sport Rays) You could also go 285/35 in the rear, but that would be the max.

Other than that the next question is: what are the offsets of the wheels? Depending on the offsets you might want/need spacers

maybe someone who is running them with spacers can chime in for you.



I do know you can run up to 345 wide tires in the rear of the Z.

Ahh ok ... I just wonder if that's possible with the oem rays

You sure they are 35 in the rear and not 30? I only ask because I am looking at running about the same size maybe a little bigger on the tires. Thanks!

no issues. tons of grip.

i dont think it will matter.

if youre on stock suspension and 20mm spacers you should be fine. that just pushes the edge of the wheels closer to a flush fitment since the OEM wheels are sucked in a decent bit.

the tires aren't oversized in the height department so you shouldn't rub. the diameters of the tires are 26.3 which I believe are just bit smaller than OEM. believe OEM is 26.5" diameter

Right now with the stock tires the 20mm spacers make it flush to the fender...I guess where the confusion is ...since i will be going with a wider tire will it stick out more if i go with your setup ? or does the width of the tire added towards the middle? hope i explained that right :icon14:

these 305 RE-11s fit so nicely on the wheel it looks like that's how they should have came stock.

the tire choice is up to you. I will recommend RE-11 based on they run just a bit skinnier than other 305s for good fitment on the stock sport wheels but they are super sticky and they are the best tire I have personally used so far on my Z.



most people go with RE-11s, Michelin Pilot super sports, or hankook RS-3's for superior traction.



if you want just a all-season or something less aggressive you need advice from someone else. I've only gone with max performance tires.

I don't want all seasons since I have snow tires. I want an aggressive look. I'll also look into the Michelin pilot ss and the hankooks. I know I also want less profile because the stock tires make the 19" rays look like 18s.

I don't feel like it takes away from the 19s at all.

I was just reading how important overall tire diameter is... and the amateur i am ..forgot to mention that i will not be replacing the front Bridgestone Potenza RE050A
F: P245/40R19

and only replacing the rear for now. As far as tire choice, and I now limited as far as what I can put in the rear? Can I still replace the rears with 305/30/19's??
Im bombarding you with question sorry man :bowrofl:

245/40/19 is 26.9" OD and the 305 rears are 26.3" OD so you're fine in that area.



now I will say 2 things on these setup you're going with.



1. a 60mm difference between front and rear widths may throw you some extra under steer. I'm at a 40mm difference and from what I've gathered and have been told it's about the top of the limit before introducing a little extra understeer. some may not notice it based on not driving their car very hard others who do will. not knowing what your plans are with the car that is up to you. this is why I went with a 265/305 set up. stock specs on sport package is a 30mm difference and nismo it's a 40mm difference.



2. It may be my OCD but I could/would never run different front and rear tires especially if one is a much higher performance rated tire vs the other. just could lead to issues if driving hard and whatnot. in a moment of desperation when my rears almost were on the verge of blowout due to inside wear I threw 2 new rears on to get me through 2 weeks until I put the car away for the winter.



i'd suggest going with 4 new matching tires and possibly bumpin up your front width. but I don't know you situation nor driving aspirations so it's ultimately up to you in the end.



in closing your current path of 245/40/19 RE050A's and 305/30/19 rears should do fine regardless of my above suggestions.

This was very informative thank you. My intentions are just to get me through this summer as a daily driver and not tracking it. I'm trying to use up and not break the bank all at once. Then switch up the fronts tires next summer

you'll probably want some 10-15mm spacers for the rear, but otherwise you will be fine with those offsets.

Does anybody know what is the meatiest (widest) tire that I can put on the stock base wheels without modifying anything? I've been searching in a lot of threads but all I found were dimensions of tires for the 19'' rays. Is there any information about the 18'' stock wheels?
