New method of automotive tire pressure detection and safe identification

The invention provides a method for correspondingly marking the most protuberant part of the deformed rubber corresponding to the outer side of an automobile tire with a white fluorescent paint line and coating a red fluorescent paint line in the position which is one second distance below from the white line as a safety mark according to the allowable normal inflation pressure standard range calibrated when the tires of sedans and miniature vehicles leave the factory (for example, the allowable normal inflation pressure standard ranges of a 1.5t FIAT sedan, a 0.6t CHANG'AN STAR miniature minibus and a 1.0t LINGYANG sedan are respectively 2.3 to 2.8 Kg / cm<2>, 2.2 to 2.5Kg / cm<2> and 2.2 to 2.6Kg / cm<2>). When the red fluorescent paint line disappears and the most protuberant part of the deformed rubber on the outer side of the tire is above the white fluorescent paint line, the tire pressure is indicated to be too low, and measures, such as inflation, tire repair, etc., should be carried out. When the most protuberant part is below the white fluorescent paint line and above the red fluorescent paint line, the tire pressure is indicated to be too high, and the measure of deflation should be carried out. The method has the advantages of visibility, rapidness, convenience, safety, practicality and low cost, and is easily accepted by drivers and tire manufacturers, completed at one time in the tire manufacturer and easily generalized and applied.
