Okay, well according to Rota's website, both wheels in 16" are 7" wide, so your tires will work fine...but first make sure that the tires you already have are the tires you really want on your Accord...remember that civics have smaller diamter tires, so you might actually want to get a different size tire for your Accord...use a tire calculator to figure out what size tire you want. Search for "miata tire calculator" on a search engine and use that one.
It's good you are doing your research this time before buying.
