Driving increases the heat of the air inside the tire and the pressure rises. A heated tire does not reflect an accurate pressure. The best pressure is that which give the acceptable ride and minimum wear on the tires. Regularly checking tire pressure and watching for tire wear is a good guide.
In 1823, Samuel Brown patented the first internal combustion engine to be applied industrially. In 1860, Belgian Jean Joseph Etienne Lenoir produced a gas-fired internal combustion engine. In 1864, Nikolaus Otto patented the first atmospheric gas engine. In 1872, American George Brayton invented the first commercial liquid-fuelled internal combustion engine. In 1876, Nikolaus Otto, working with Gottlieb Daimler and Wilhelm Maybach, patented the compressed charge, four-cycle engine. In 1879, Karl Benz patented a reliable two-stroke gas engine.
On January 29, 1886, Karl Benz received a patent for a crude gas-fueled car, which he demonstrated later that year on the streets of Mannhelm, Germany. And in 1893, Charles and Frank Duryea, of Springfield, Massachusetts, built the first gas-operated vehicle in the U.S.
