Why do cars explode easily when filled with oil in summer?

The main reason: with the increase of gas temperature, the molecular movement becomes more intense. At 30 degrees Celsius, the tire is inflated at a pressure of 2-3 bar. When the tire rubs against the ground to generate heat, and the heat generated by the friction between the brake pad and the brake disc is transferred to the tire through the rim, the gas molecules in the tire move violently, so that the air pressure should reach about 3 bar. If the tire pressure exceeds the normal value, there is a possibility of puncture. In order to avoid puncture, nitrogen can be filled into the tire in summer, because the molecular movement of inert gas does not change much after heating. Or an aluminum alloy steel ring with good heat dissipation is used,
