Help me with some fitment questions?

hey guys, first post here on stanceworks, ive been looking around for a good while though. so i have an 09 bmw 328i sedan and am about to start putting the wheel project into the works. i guess my first question is tires. sorry if i sound like an idiot but ive never had to figure out what tires to put on a car other than replacing what was already there. so ill be running staggered LM reps that are 19x8.5 and 19x9.5 on a stock suspension for now. however, i will probably want to tuck the wheels up in the wheel wells in a year or so when i can afford it (aka drop it about an inch all around) so basically i just want to know what tire setup to use and if i should stretch and if i should how much. im not exactly clueless but guidance woud be helpful, and like i said i havent done this before so any help is greatly appreciated, and if i left anything out let me know. thanks in advance guys.

So youre going just for looks - no clearance issues - until you drop the car. As long as youre not lowered id recommend you some tires close to stock sizes. Im not a BMW guy but have a look at may the E90 M3 wheel/tire combo

Front: 245/35 R19 ET 29 (8,5) -> tire wall of 8,5cm

Rear: 265/30 R19 ET 23 (9,5) -> tire wall of 7,9cm

Id now look into some affordable tire. Maybe a 225/35 which has a tire wall height similar to the M3's rears...

Problem with stretched or really low profile tires that your car will look like its raised - which you probably dont want right?

yeah exactly i dont want it to look awkward, and i want to fill up the wheel well as much as possible for now. i was thinking of doing 245/35 fronts and 265/30 rears anyways so thats perfect. last question i guess is i know my offsets are not that aggressive, if i threw some spacers on without the car dropped will it look awkward as well? in my head a flush wheel would look better regardless of gap between the tire and the fender.

Id say small spacers (maybe 10 to 15mm) will be alright but the more flush the wheels sit the more you place emphasis on the wheel gap...spacing them out too much will result in a nasty 4x4 status...
