My Saxo was lowered 40mm with 16's on and the tyres were 45 profile. It wont be easy to get 17/45's on. imo 17's are way to big same with 16's. I put 16's on mine because the lip makes it look smaller. Also the ride will be terrible.
imagine what it would look like dropped another 10mm and and inch bigger wheels and the tyre profile will be the same
