OEM front is ET29, so ET33 is 4mm plus 15mm as the tyre goes from 245 to 275. Wheel width does not matter because the tyre increase is wider than the wheel.
But as you said, most likely 19mm will not clear. |
You are correct about the et29 offset. The et31 I remember is from the 1M.
However, the stock 245 is stretched on the 9" wheel. If anything protrudes past the outside it will be the rim protector portion of the tire. I don't think that the rim protector of the 275 on the 10" wheel will stick out further than the protector of the 245 on the 9" wheel.
If you are comparing tread widths, the top of the wheel will have a 30mm total difference, or 15mm per side. However the widest part will still be at the rim or the tire protector on the rim.
That said, after doing a quick search I found a thread where they tested the 18x10 et33 EC-7 with 275/35/18 on a F82 M4 and they cleared the suspension. Seeing as the M2 utilizes a lot of the same suspension components the et33 with 275 might actually work.
