Overall diameter of the given 15's are larger than what you have now. So if you're rubbing or at least experiencing some problems with your 17's (I'm assuming you're running 205/40/17 tires) it's going to be worse with those 15" size tires.

Unless you get those 15's and get some new rubber to go with them of the proper sizing.

They might work. Anyway to test fit before buying?

Rubbing doesn't all have to do with tire size, but also wheel offset. The correct size for Civics are 17x7" with 42-44mm offset and 205/40x17" tires. For 15s 195/55x15" or 195/50x15" are the prime. Pretty sure with plus/minus sizing 185/65x15 or 185/60x15" should work too, but your gearing will be off a little and your mpg will change too.

If you're using 15's go with 205-50-15 or 195-50-15. I didn't think Mini Cooper wheels fit because I thought they were 5 lug. Make sure they're 4x100 mm bolt pattern.
Post a picture of what wheels look like.

That is insane ballooney for a 15 on a civic. To get stock rolling diameter, you'd have a 50 series tire, or maybe 55 with a 185 section width. 65 series sidewall is huge, any way you cut it.

OK, so here's the breakdown:

205/50-15 = 23.1 diameter, 72.5 rolling circumference
185/65-15 = 24.5 diameter, 76.9 rolling circumference

So it'll be an inch and a half bigger than stock, and will roll 4.5 inches farther every rotation. It will also handle like garbage and look silly, but it's your call.
