Got the following tires mounted to the new wheels earlier this week, took some pics in reference to how wide the rubber sits past the wheels for anyone else debating on what tire sizes to go for on similar sized wheels as mine.
I'm not a fan of any amount of stretch whatsoever, so I'm extremely happy with the sizes that I purchased since having a slight amount of rubber extending past the wheel surface is exactly what I was hoping for.
My setup:
Front - 19x9.5 ET23 TE37 Ultra wrapped in 275/30R19 Michelin PS4S
Rear - 19x10.5 ET23 TE37 Ultra wrapped in 295/30R19 Michelin PS4S
The rubber extends past the outter rim of the wheel by about 3mm on the rears, and 4mm on the fronts. All pictures below are of the rears (besides the wheels standing upright in the background, those are the fronts):
