Hey guys, total newbie here with a quick tire question. I have OEM style 361 wheels (8x20" ET36 front, 8.5x20" ET47 rear; OEM tire sizes are 225/35/20 front 255/30/20 rear). I've already replaced my rears with 255/30/20 MP4S tires, and am planning on getting a pair of MP4S tires up front to complete my set. I've also been planning on adding spacers on all four corners. My car is currently lowered on H&R Supersport springs, so my biggest concern is avoiding rubbing issues.

My first reaction was to replace my OEM tires with the same 225/35/20 size and then add spacers (10mm front, 12mm rear). Would it be possible to just put on 235/35/20 tires up front and no longer need the spacers up front? I've done some digging and it seems like 235/35/20 should work with these 8" wheels, but I'm not sure if the lowering springs affect the answer.

RWD or xDrive?

With RWD just use 245/30-20 up front without spacers, and add 15mm (or 18mm) spacers for the rear wheels.

With xDrive it's a bit more complicated.

Thank you so much for your help!

I am RWD. Do you think that would be fine to avoid rubbing issues as well, with in mind the H&R supersport springs I have on as well?

Should be no problem.

245/30-20 is slightly shorter than OEM 225/35 front tires.
