NOw, I'd like to keep the steel wheel as it is and change the tyres to 185X55 R13.

Is it a proper change?

Has anyone tried that?
Any idea on the possible sidewall scraping?

I can just add that fitting 185 tyre on a 13 inch Steel Rim is not recommended. If you wish to go ahead with 185, then upgrade to alloys (upsizing is an alternative too).
