I have looked at some of the threads and online tools, but wanted to check in with you guys who have more experience. I have a 2013 M56S, stock height. I am looking at Rohana RFX5 wheels 20x10 with an offset of +22 in the front and +40 in the rear. I am trying to verify what tire size would clear either 245/40/20, 255/40/20 or 275/35/20. I am open to the 275 rears and 245 or 255 front if needed. Would any of these work stock height? I am open to RS-R lowering springs, but have had some trouble finding a shop to install (in the Sacramento, CA area). I appreciate any advice. Thanks in advance!

I saw a post with Rohana RC7 20x10 et+25 front 245/40 and 20x11 et +28 rear 285/35 with coilovers. No fender mod, no rubbing.
