Pretty sure those are 17x8's.
I think the only option for 17x8.5 is a +40 or +30 that would be remotely close to fitting our cars and the +30 would not work unless you were going for that stretch look and ran massive negative camber. I was going to get RPF1's about 4 or so years ago and decided against them cause the only real option was the +40 in 8.5". I wanted to go with something closer to a +45 so I could use spacers to get the right depth if necessary and it wasn't offered with the 8.5". Easier to space the wheel out than figure out how to bring it in.
Anyway, if those were 8.5" wide they'd stick out way further and your tires would a more rolled sidewall, less vertical.
