Ride Quality. 17s are a more comfortable ride.

Noise. 17s are a little quieter.

Venerability. The 17s are less vulnerable to damage --either curbing or bends from potholes.

Tire Choices & Cost. The choices for 17s are plentiful and the cost is cheaper.

Weight. The weight of a 17" wheel + tire is usually (at least a little) < than the weight of an 18"+ combination.

Aesthetics. This is subjective. The 18s are probably the sweet spot, but I like the way 17s look better than 19s.

Square. I prefer a square set up over staggered. Probably another whole topic by itself.

I am a function over form guy -- How it works is more important than how it looks.

Truth right here

I'm installing a set of second-hand 17" winter tires on my new-to-me 2015 235.

The stock wheels are staggered 18". Pressures are set to 33 front, 38 rear.

What is the recommended pressure for 225 17" square?

I set my 225 17" winter tires to the same pressures that are recommended for my staggered summer tires, and it doesn't seem to be an issue.

Winters are on, just after first hard frost here in DC area. Turned into a project.

I couldn't get the lug nuts off with my home compressor/wrench, so I took it to a small tire shop nearby. They broke the lug key on the second wheel. Those BMW locks are very good - the shop tried their 'special tools' but couldn't budge the locked lugs.

Drove the car with the one 17" snow and three 18" summers to the BMW dealer, where for a small (hah!) fee the locks were extracted with the master key and the swap completed.

I like the look with the square 17" wheels. Ride is very smooth with a bit more tire noise than the summers.
