Tire repair tools generally include tire patches, air chucks, stitchers&scrapers, air hydraulic pumps, combi bead breakers, cross wrench etc. . A tire pressure gauge is a tool for measuring the tire pressure of a vehicle. There are three kinds of tire pressure gauge: pen tire pressure gauge, mechanical pointer tire pressure gauge and electronic digital tire pressure gauge, among which digital tire pressure gauge is the most accurate and convenient to use. Air pressure is the life of the tire, too high and too low will shorten its service life. If the air pressure is too low, the deformation of the carcass will increase, and the side of the tire is prone to crack, flexing movement, resulting in excessive heat generation, causing rubber aging, cord fatigue, cord broken. The insert seals is a kind of unique cold-resistant and heat-resistant technological formula, which is used for the adhesion, repair and beating of the tire and the tread, make the repaired tire can adapt to all kinds of road environment, effectively improve the wear rate and service life of tire retreading, and make retreading tire more beautiful.
