Ok, I have done a thorough search and found that the opinions and statements are all over the place and are far from definitive. Too many "widest tires" threads deal with stock 18's.
I have a 2014 507 Coupe. Stock to the bone. 8 x 19 and 9 x 19. I want to replace my stock tires with 255-35-19 in the front and 275-30-19 in the rear (from 235 and 255 respectively). WILL THEY FIT WITH NO RUB?
I don't recommend 255 in the front though, a bit wide for the 19x8... it might feel unstable with bulgy sidewalls. But I'm sure it's not as noticeable on 19's than it would be on 18's.

Agreed.
Just do a 245 and call it a day. No reason to put that wide of a tire up front especially on a 8" wheel.

I'm not concerned about the 275-30 in the rear. It seems almost unanimous that a stock 507 can accommodate that size. I'm concerned about running a 255-35 in the front.
Admittedly, I know little about tire sizing. I just thought that it might be a good idea to go up 20mm on each axle to keep the car from detecting a differential between front and rear and potentially affecting the ABS or traction control calculation.
On my 2009 C63, I had random traction control warning lights when exiting spiral offramps after replacing just the rear tires. Presumably because the computer was detecting a change in rolling distance between front and rear due to new tires in the back and old ones in the front. I'm less concerned about this, though, than I am rub. I'm also not concerned about a slight loss in handling due to sidewall height. I'm 50 years old and drive this car fairly conservatively. No crazy G's ever.
Bottom line, if 255's in front will fit, I want to run them if they won't look dopey.

You're more concerned about how a tire looks than how it fits and performs? Wrong way to approach it.
The answers are in here... Get 245's in the front, and 275's if you want for the rear. Many people run these sizes just fine. Virtually nobody runs a 255 in the front on a stock wheel, I don't think I have ever seen it here.
If you're worried about sidewalls matching perfectly (which really wont be a problem with 245/275) then drop down to a 245 and a 265. After all, you're 50 and drive conservatively so you wont notice a difference between 265 and 275.
Unless you're into having below stock performance and a mushier feeling in your steering.

As to your first point, not exactly. I doubt seriously that my driving style will reveal ANY performance deficiencies so I'm not really choosing between looks and performance. I'm choosing looks and likely identical performance to me.
Second, when I do push the car near it's limits, it's usually in a straight line. Rarely, if ever, do I test the limits of a tire laterally. Therefore, that steering mushiness you describe will probably never be discernable to me.
That said, I'm going 245 in the front. The tire mfg recommended at least an 8.5 inch rim for the 255 I was looking at. I should have looked there first.
Congrats! Sidewall bulge will really depend on the tire brand. Each brand will have varying section width even though they all say 275. For example, Nittos tend to run much narrower, so you can go as wide as 285 with a Nitto, but not with a Michelin PSS.
After you get some miles on them, you'll have to report back on how those tires perform. I drive hard enough, and enough miles that going through PSS might get too expensive, so I may need a bit cheaper alternative for just daily driving.
Installed the Sumitomo HTR Z III's today. 245-35-19 and 275-30-19. Pics below. Surprised to see almost no additional sidewall bulge in the rear.

Looks amazing! I've been contemplating what to do with my tires since I need to change them and I want to go wider. Can you post more pics like side profile and show us the wheel gap. Any issues with rubbing esp on the rears? I'm looking to do 235/275 Michelin PSS for my 507
I can tell you the 275 rear is a great filler. Granted, I am running 18's, it looks great! Unfortunately I have no pics yet but if I get some good ones I will post them.

I'll take some more shots tomorrow and get you an idea of what the increased tire size does to the fender gap. I like what I ended up with.
I recently installed PSS tires on a 507 sedan (OEM wheels) -- 265/30 R with 10mm spacers, 235/35 F with 12mm spacers. Also lowered on H&R springs. Rides great with no rubbing.
