Everything I've read and see says that the wheels should be the same as the 2018 Civic (and the 2017 Civic that I have - the tires are the same size). However, that's for a full size wheel. Here's a link for a thread for a compact spare (which will fit in the Insight trunk) - there's also parts info for the jack - and I think it is the same as a Civic jack.
