A catalyst for the production of methyl isopropyl ketone containing aluminum and titanium oxides, treated with Group 1 or 2 metal hydroxides, or their salts. In the pneumatic tire with such a configuration, even in the case where the electronic circuit device is mounted on the tire inner surface and liquid such as puncture repair liquid is injected in the tire at puncture, there is no possibility of damaging the electronic circuit device due to adhesion of the liquid to the electronic circuit device such as an air pressure sensor. The element is present at the first side and coupled to the connection layer. While the embodiments of the invention have been disclosed, certain modifications may be made by those skilled in the art to modify the various size of the tube as well as the size of the bit or the size of the standard threaded hole to accommodate particular applications.
