Since you are at it, please post close-ups of the tires with the fenders. Interested on how much they stick out. Front and side shots of those close-ups would be great
Thanks.
Thanks.

All you have to do is look at the closeup picture of the tire on the rim. Its not as though the tire is bulging out excessively past the wheel , or at all
345's fit this wheel just fine, the only thing people have reported is throwing the occasional error codeSo OP, have you had any sensor or error codes thrown with these larger 345's like other have occasionally reprted

The sidewalls on the Michelin's are typically softer than the GYGEN:2's too which equates to a less crisp steering response. It's the main reason I stick with the GY's.

I don't think they look narrower but I don't think they look wider. I just see more sidewall and a "fatter" tire.

I'm still on my factory originals and I really don't mind the ride or noise. I know that the Bridgestone 325's do look narrower but I thought for sure the Michelin 345's would look wider. Could be the camera angle too.

The M PSS tread on the 345/30-19 is 1.4" wider than the gen2 GY ROF's 325/30-19. The overall section width is 0.8" wider

It was 40 degrees out here in Cincy yesterday. 
Took the car on 3 freeway trips and watched the tires warm up on the DIC from 29 to 32psi.
Then, on the way to dinner last night- with warm tires- I was driving a wide swooping on ramp and once the road straightened, stabbed it in 2nd at about 40 mph.
I have never felt my car pull like this.
Tires stuck and catapulted us to redline with no skipping, hopping or sideways drama.
I then tried 1st from a roll. Lost grip at about 4k rpm.
On the bright side - the loss of traction was predictable- not the normal hopping and drama experienced with the stock GY's.
Hopefully warmer temps will allow the tires to stick more! My fingers are crossed cause the headers and cams are going in next week!
I'll be sure to get better pics when we get a nice sunny day. Supposed to be 60 on Tuesday.

Here's what I have:
For the price the NT05's are hands down the best bang for the buck.
Currently I'm running the Mich's PS2 stock sizes and they offer the best grip with very predictable behavior, but cost more.
If you put a 345 on a stock wheel you're not getting the full benefit of the wider tire and you're carrying the extra rubber.
I run stock tire sizes on rims wider than stock rim sizes not the other way around. I've tried that too, and it's a waste of money.
The proof is in the G meter that I can consistently max out.
That's how I rate the available grip of a tire.
Haven't been able to pin the G meter with the NT05's yet but been close.
Now it's time to choose!

BLW By, where my NT-05's pulled 0.93 and 0.98 G, my new stock sized PSS pulled 1.07 and 1.08G. The NT-05's were 295/335 although the 325PSS were wider than the 335's. Both are on OEM rims.

Take that a step further on wider wheels and you've got a better handling ride.
Just trying to help, but if you all want to put the bigger rubber on, by all means.
Just curios if anyone would like to calculate (guess) on how many tire combos I've R&D'd in my 88,000 mile venture in 5 years.
