Wheel / Tire experts here?

I recently lucked out on a find from Craigslist.

Found 17" wheels for my snow tires that apparently used to be used on a BMW X5.

Center bore is a match, along with bolt pattern. (They are not BMW wheels, though they look similar to the early X5 model 17" wheels)

The differences are what I'm curious about. Instead of my stock wheel size of 17x8, they are 17x8.5 and the offset is et43 instead of et46.

The offset doesn't concern me, however the slightly wider wheel shows a noticeable decrease in my sidewall flex since it's stretched over slightly.

What I am curious about is whether this is a problem (though I doubt it is?) and whether or not my tire pressures should be lowered slightly for the increased sidewall stretch?

I tried looking through Google, but not sure how to sift through the wealth of hits to drill down to the info I want.
