Hot vulcanizing patch is highly reliable. It can completely ensure the safety of the tire. However, the hole caused by the nail should not be too large; holes smaller than 2 millimeters can be securely repaired. Below is an introduction about tires: 1. Introduction: Tires are circular elastic rubber products mounted on various vehicles or machinery for rolling on the ground. 2. History: In 1845, R.W. Thomson, a civil engineer born in Scotland, invented the pneumatic tire and obtained a patent from the British government under the title "Improvement in the Wheels of Carriages and Other Vehicles." On December 10 of the same year, the first pneumatic tire was born. Tires are usually mounted on metal rims, supporting the vehicle body, cushioning external impacts, ensuring contact with the road surface, and maintaining the vehicle's driving performance. 3. Function: Tires are often used under complex and harsh conditions. During driving, they endure various deformations, loads, forces, and high and low temperatures. Therefore, they must have high load-bearing, traction, and cushioning performance. At the same time, they are required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation. Half of the world's rubber consumption is used for tire production, indicating the significant demand for rubber in tire manufacturing.
