The common automobile tire can be a very useful thing if you're looking for a certain shape of centering for building stone arches in dry laid work or mortared work. These fellows who cryptically call themselves Stone_Decor working out of Amman Jordan, have conveniently found a set of all-season tires to form keyhole openings in some sort of rustic faux dry stone palace they've been building all this season.
Wonder if they are Firestone tires or Bridgestone? I wonder too what the 'sidewalls' look like. What ever size and style they are, Im sure they still need to be rated for the correct pressure. And of course they'll need to be balanced!
