I buy the arguments for the summer, but for winter your car will handle worse.

I would go with what BMW designed in terms of widths for winter running. They did a lot of testing to work out what worked best.

Out of interest my winter set is 225/45/17
Thanks for responding. To be clear, I'm in Florida. It snows about once every 30 years here (and just flurries) . Our roads are pretty good, partly due to year round mild to hot weather. I run summer tires year-round.

I'm running DW all around. My guesstimate for difference in 8 vs 8.5 161's is 1 to 1.5 lbs (per the bathroom scale). Tirerack claims difference between DW 225 and 255 is three lbs, so if I stayed with DW, the increase is ~4 lbs up front. To go with DW 245/40 sq, front would gain ~3 and rear would lose ~1. To go with PSS 245/40, increase is 5 lbs and rear increase is 1.

I'd love to make the lightweight wheel play as part of this, but again, not in the budget.
