Anyone running 285/75R17 with fiberglass?

Coming up on needing tires soon and wanted to step down from my 315/75R16 as they seem like a little too much.

I’m going to switch over to 17” wheels and wanted to try a skinnier 34/35” tire. My local Schwab was recommending a 285/75 as its 34” and 11.2” wide. So I’m losing a little over an inch in width and about a half inch in diameter.

Just trying to see if that would look ridiculous with my glass fenders or not.

 

Pictures would help. Also what fenders and length arms?

 

McNeil 4” flare, +2” total chaos arms. There’s also wheel spacers up front, I wanna say they’re 1 1/4” but not certain. Would like to get rid of those if possible with a different offset wheel.
