Yeah I'd like to find more coupe guys running a 255/40/19 square set up

 

Not sure if he has any others on site but he's a +18, you'd have 12mm more to go out if you want more tire. Staffer Lt8che was running 18x9.5 +30 on 265s and his fitment was spot-on, but 265s aren't as easy to source

 

The 265/40r18 on the 18x9.5 +30 fit perfect with the eibach drop
The 275/40r18 on the 18.9.5 +35 fit pretty well too, a slight tuck

 

I'm starting to look around for new tires to go with my summer wheels, Vertini RF1.1 19x8.5 ET35. Typically I've seen the usual setup is 245/40/19, but would a 255/40/19 setup be acceptable also?

Noticed a 255/40/19 setup here: https://www.myg37.com/forums/19/2765...ml#post4165705

I do have an AWD sedan and currently at stock height, with a potential drop planned either with Swift or Tanabe lowering springs.

245/40/19 = -0.1% Overall Diameter Decrease
255/40/19 = 1.1% Overall Diameter Increase

Thanks,
Matt

 

255 on 8.5 is safe, and will look good IMO. I have 255 on 9.5 all around and it looks a little stretched for my tastes. I wish I had gone with 8.5 square. But yea no worries about that size. You may want to think about running a spacer too. 9.5 + 35 is about perfect on a lowered sedan IMO, which translates to 8.5 + 22.

 

Either of those options will be fine. The 255 will give you a little more meat and a slight tire bulge, but I think the 245 will look the best since it's only 8.5.

 

I've read through this thread a lot but I still wanted some opinions on a possible set up on my 2011 G37x Coupe:

Wheel: 19x9.5 35mm offset
Tire: 265/40R19

Not lowered or anything.

Thanks!

 

On a coupe I would shoot for +25 or even +20

 

If he's not planning on lowering, the +35 will be fine with OEM camber. You'll poke a bit with the +25 at stock ride height. The 265/40R19 will be a bit tall (27.3 inches overall, stock is 26.7), but again, at stock ride height you shouldn't have any problems. If you want an exact match to OEM, 275/35R19 will still fit with plenty of room on a coupe, without bulging too much (depending on the tire you choose).

 

Thanks for the info guys. I'm not 100% on all of the wheel terms but I'm assuming poke means "sticks outside of the wheel well"? I definitely want to avoid that. My goal is to get as close to flush as possible and not have a "stretched" look.

There's no plans on lowering in the future so it looks like this setup should work then. Thanks again for the help!

 

Yea you are right. +35 will be better.

 

Welcome to the site, looks like you've been put on the right path
If you do choose 265s I would go w/ the 35 series, like Chaos mentioned the 40 series will be about .6" taller and over 2% taller than oem size. The 35 isn't great (diameter-wise) at almost .5" shorter but better than the 40.

Also keep in mind the 265 widths are a bit scarce compared to a 255 or 275 width, so I'd lean towards either a 255/40 or 275/35, these are much easier to find as far as the tire models and might be cheaper???

Only caveat w/ 275s is the wider tires in front will tend to slow your steering response and may be more prone to tramlining. But they DO look badas$

 

This looks like a screamin deal on these wheels, but I have a hard time believing that A: they're authentic and B: they actually have stock. This website has downright frightening reviews across the board, so I was curious if anybody here has actually dealt with them before . . .

Assuming this is legit, I'm curious if I could use (4) of these for a square setup on a G37xS Sedan. The +47mm offset I'm thinking might be an issue.

 

47 offset won't be an issue, since they're 9 wide they will fit close to where the 8.5 +43 would at the fender edge.
Check this site first since it's an actual Nissan dealer, only a few bucks more and they should be able to tell you the true availability of these wheels.

Found those a couple years back for an even better deal but no one was able to land them.
G/L and let us know what you find out.

 

Intriguing, I'll check it out. Thanks! Do you know of anyone that has put these wheels on a G sedan? I'm curious what they'd look like.
