So from what ive read so far, it seems the best combo for stock rays 19s is:

245/35/19 Fronts
255/40/19 Rears

I really didnt want different sidewall sizes for the fronts and rears i think i would focus on that way too much and keep staring at it..

Are there any xxx/35 sizes for the rear that I could use? Ive also thought about doing 275/35 which i have now but still wondering if i should go back to the "safe" route

 

245/35 and 255/35 aren't really that noticeably different so you could go that route no problem.

Other than that, all I would suggest is running 245/35 square or 255/35 square and just running an oversized tire in the front. You don't have many options due to the very small stagger on the OEM 19s.

BTW, 245/35 and 255/40 isn't a very good set up, just realized that's what was suggested and I suggest against that personally.

 

I am 245/35/19 255/35/19 feels good with my new v12's. I'm thinking of going 235/35 255/35 on next change.

 

thanks guys went with your advice and got 4 new V12s
245/35 in fronts
255/35 in rears

so far so good!
