tire advise... switched to 275/35 not happy..
I switched to 275/35 and 245/40 and honestly I do not like the look. The sidewalls are just too bulky its too much meat. I'm running PSS and want to stay with PSS for sure
I just cant decide if I should go back to stock size PSS or maybe go 265/35 in the rear and not sure front. Anyone have any suggestions for me?

Im running stock sized pss and i have to say theyve got a pretty wide sidewall fills the gap decently but i think 265 in the rear might be the perfect fit
The stock size on the front looks good to me with the pss

and I like the results. There is almost no discernible additional sidewall bulge and the slight increase in sidewall height fills up a little fender gap quite nicely IMHO. Since I am not going to lower the car, the additional rubber is the only way to fill the open space.

Why did you bump up the aspect ratio AND tire width? When going wider, most folks either reduce the aspect ratio or leave it the same. I just went from the stock setup:
255-30-19 F
235-35-19 R
to
275-30-19 F
245-35-19 R

I was always under the impression stock was 40 front and 35 rear?

275/30 is a 1/2" shorter in height than the 255/35 whereas a 275/35 is less than 1/2" taller.
And these cars need a little extra sidewall on the rear to look right IMO. The 255/35's on my car look like ****, so I would have done the same.
OP, do you have pics you could post?

From your pics, 275 rears don't look too tall to me. I am running 265 with stock aspect ratio in rears, stock size fronts and they look fine to me, but they are bridgestones. I'm going to go 265 PSS next time around.

What is the problem actually? Look / fitment / performance ?
Based on your pictures I don't see any problem apart from the fact the rear are bulkier but it fills the gap pretty well. I assume you are not lowered?
It seems you will enjoy better traction as is

Does the bigger tires make your car look higher/taller off the ground??
I have stock wheels and I'm thinking about going wider, but I don't know much about tires at all so I've been reading threads about tires and I'm still confused.
I have 18's I want to go 275 rear and 245 front
The dealership told me stock is
F 235 40 18
R 255 35 18
But people are talking about aspect ratio and stuff and that has me confused.
Can someone explain this to me?
What are the positive and negatives of going wider?
Thanks

I wanted a wider more aggressive look... I didnt care about performance or tranction aspect. I just wanted more aggressive
after making the switch its just too meaty for my taste, I'm more of a all wheel no tire kind of guy. I should have went 35 front and 30 rear I think.

For 18s those are the stock aspects with 235/255. That makes the rear smaller than the front though. I run 235/40 and 265/35 on my 18s. I think going down a size would make them look less chunky. The new M3/4 on 18s has MASSIVE sidewalls. They look like truck tires!

The second number (30, 35, 40, etc) is the height of the sidewall as a percentage of the width. So a 275 35, for example, would have a sidewall height that is 35% of 275mm. We can do simple calculations to try and keep the height the same as stock with wider width, but sometimes it doesn't work out exactly.
