There's nothing on the box? Are the edges angled instead of 90°? Put two together and see if there's a gap formed. That's how my last two tile projects worked. Of course that's only if you want the minimum spacing.

I cannot get the photo to load, yes, tile is with bump out. The box doesn't say. Wondering long term if there are buckling issues with them close together...

Post a picture of the tile in a comment . But in most cases you will need some space for the grout or you will have a really big mess in about a year.

If there are bumps on the tile those align when the tile is installed and creates the correct spacing. No issues with expansion and contraction with ceramic tiles.

The edges appear to be smooth so you need spacers. Or post a photo showing the entire tile.

Google tile lugs and you see the kinds of bumps/nubs people are talking about. It doesn’t look like your tile has them

Yes, you need spacers, I just finished a kitchen with the same tile and used 1/8" spacers
