How many holes can you count?

No real dramas, pulled it over, spare on, off we went. But then this week I've been trying to get a replacement 185r14C for a spare. Good lord do they not make them anymore? Ended up getting a part worn as it was all I could find. Was I just having a bad google day getting one or are they super rare? Plenty of car variants but no 'C' ones. Is the 'C' that important, can you get away with normal ones?
Still on the plus side poor replacement tyre availability will help me justify getting some alloys on with the mrs
