What are the reasons for solid tire scrapping?
2 Answers
Solid tires are scrapped due to reasons such as expired vulcanization time and issues with solid tire rubber compounds. Below is an introduction to the causes of solid tire scrapping: Expired vulcanization time of solid tires: If the vulcanization time of solid tires expires and the mold is not opened in time, it can lead to over-vulcanization and aging. Solid tire rubber compounds: Uneven mixing or heating of the rubber compounds for solid tires. Poor insulation of the tire embryo: Poor insulation of the tire embryo and temperature fluctuations in the vulcanization machine can result in under-vulcanization. Harsh actual usage environment: A harsh actual usage environment can cause the tire to be cut by external forces. Corrosion: Exposure to chemicals during application. When the tire wears to the wear limit indicator: When the tire wears to the wear limit indicator, it must be discontinued (i.e., when the tread pattern depth is below 1.6 mm). Tire and rim inspection: First, check the compatibility between the tire and the rim, i.e., whether the tire specification and model to be installed match the rim model. Rims of the same specification may vary in width, so this should be confirmed before installation. To ensure smooth installation and reduce friction between the tire and the rim, the inner hub of the tire and the outer surface of the rim should be sprayed or coated with a lubricant during installation. Common lubricants such as soapy water or detergent water can be used, or specialized tire lubricants if available. However, industrial lubricants like grease must never be used as they can swell the rubber and damage the tire.
I've been operating forklifts at construction sites for over a decade. The most common reasons for solid tires to be scrapped are being cut by hard objects or getting crushed out of shape. These tires aren't afraid of nails, but they can't withstand long-term overloading or rough handling. Especially when turning, the frame squeezes and deforms the rubber, which eventually leads to chunking and material loss. One vehicle in our fleet wore out two tires in just three years - when we removed them, the steel wires inside were already exposed. Chemical corrosion is another issue - last time a barrel of cleaner leaked in the warehouse, the tread became as hard as plastic. We always need to watch for penetrating cracks or localized bulges on tires, as these usually mean replacement is necessary.
