35 offset on 18X8.5 wheels?

So tire rack states these will work on the F30 but to me something seems off.

BMW stock wheels 18X8.5 (on a staggered setup) use 47 offset, so won't these have some issues with a 35 offset and that same width?

actually those 47et are only factory specs, factory specs are very conservative and sink in. on the aftermarket side anything from a 18x8.5 35et -45et will work but i would stay close to the 35et, 38et. now as for a staggered set up like a 18x9.5 do 45et

Correct! Generally stock wheels are very conservative, allowing for a slightly wider wheel and/or lower offset.

8.5" ET35 can work perfect on all four corners. If you wish to go staggered, 8.5" ET35 Front & 9.5" ET45 rear will be a perfect fit.

These should fit no problem. We have run this sizing on F30s already.

Now my plan is to use these on a future M3 as well (in 3 years). Will I have any issues with that? I am guessing I will need spacers for the rear since it will be flared out more.

M3's traditionally can take much wider wheels than standard 3-series. In fact, the OEM M wheels will likely be wider than these are which would make using these on an M a bit of a downgrade.

Maybe purchase new wheels later down the line?

Please don't do this. M3 deserves the concavity. Not wheels with spacers.

These would be for my winter set up on the M3 not my main wheel. And I wouldn't want any thicker wheels than 8.5 for winter.
