Switch to 17?, or stay with 18

[lane47]

My 2025 TRD Sport came with 265/65/R18. After 10 to 15 thousand miles I plan on new tires and wheels. I would like a slightly taller, and no wider (even narrower) tire.
Since I plan to buy wheels, is there a practical, or performance reason to stay at 18, or to switch to 17?
I don’t offroad, an occasional gravel road, but 95% paved, with little interstate driving.
would there be a weight savings with an 18 over a 17, for same height and width, or would the slight reduction in amount of rubber, be offset by extra bead material?

17’s are lighter, have more size options and usually cheaper tires.

I am actually trying the opposite direction. I have TRD OR and picked up some take off 18” wheels (same TRD OR style) to go with a 265/70r18. I wanted a 33” tire but didnt want to go to a wider 285/70r17. Lots of choices in the 265/70r18 size. I will probably go with Falken at4w’s in sl.
