The rears offsets come in 35, and 40. Which offset would give me a nice flush fitment? I was also thinking 295/30. Thanks for tour help. Also if you have pics, please post them.

I am running 20x9.5 +17 F and 20x11 +37 R with 265/30/20 F and 295/30/20 R PS4S tires. I think this fitment is pretty much spot on with no rubbing at all front or rear and my car is lowered on Bilstein coilovers.
If you are stuck on a 20x9 front, you can probably get away with a +15 offset without issue. I would NOT recommend 255/35/20 F paired with a 295/30/20 R. The front tire would be very slightly taller than the rear tire (27.02" F vs. 26.97" R). That will look whack and will cause significant DSC interventions as the car is expecting a front/rear tire stagger where the front tire is a good .6" or so shorter than the rear tire.
I'd go for 265/30/20 F and 295/30/20 R or if you want to stick with 255s, get 255/30/20 F and 285/30/20 R to stay close to stock stagger.
Here's a picture showing my fitment:
