Prius 17s

[Maverick06xx]

Hi all,
I'm new to the site and wanted to ask you all about wheels. I'm looking at upgrading my 2008 vibe wheels to 17s. My model has the 16s steel wheels and I wanted to gets 17s. The stock 17s vibe wheels are expensive and can hardly find them however, I found a set if 2011 prius 17in wheels. The owner of the wheels doesn't think they will fit the vibe because of the offset. The prius wheels ar 17x7 and offset is 50mm. The stock 17s are also 17x7 and offset is 45mm. I tried searching dor pictures of prius wheels on a vine and had no luck, any help? Will they fit? I'm at stock height and not lowered.
