Ben - Question regarding sizing. I know BMW recommends a square 235/40/18 setup (which I'm fine with) but this is almost an inch shorter than OEM rear so it'll hurt mileage as well as add phantom mileage. A 235/45/18 is .02" taller than OEM rear while maintaining the 235 section width as recommended but is roughly .75" taller than the OEM front. Would there be any problems running this size in the front? Any reason this isn't the recommended size, other than it being slightly larger than BMW's recommendation?

The only real snow I have to deal with is a few unplowed roads before I get to the priority and B roads before I get on the Autobahn. The priority and B roads and the Autobahn are all plowed regularly. Once I'm on base everything gets plowed eventually but then we only have a 50kph limit. Would a staggered setup be ok, or even preferable?

My M won't be here until mid January so I have a little time left before I have to buy but I want to consider all my options first.

Thanks.
