Should Car Tires Be Stored Vertically or Horizontally?
2 Answers
For long-term storage, car tires are generally placed vertically because the sidewalls are thin and horizontal storage can easily cause deformation. However, if the tires are mounted on rims, they should be stored horizontally to ensure even force distribution and reduce the risk of aging. When stored horizontally, the force is concentrated on the sidewalls, which are relatively thin. If tires are stored horizontally for an extended period, the increased pressure on the sidewalls can damage their structure over time, potentially leading to deformation. The tread, being thicker and harder, is less prone to deformation when stored vertically, but care must be taken to avoid squeezing the tires. It is best to use a rack to support them. Tire Storage Precautions: As tires are rubber products, they are susceptible to expansion and contraction due to temperature changes. During storage, they should be kept away from direct sunlight, heaters, and similar appliances to prevent deformation. Tires should be stored in dry, well-ventilated areas to avoid damp environments, as moisture can accelerate aging and rotting, ensuring the tires remain unaffected. Keep tires away from chemicals and oil-based products, as contact with these substances can cause corrosion and aging.
The way tires are stored is really important, and I think it's best to store them vertically. I once tried stacking unmounted tires horizontally in the garage, and after a few months, I noticed some deformation on the sidewalls when I took them out, which made the car unstable at high speeds. Storing them vertically helps maintain the tire's original shape and reduces pressure on the sidewalls. Also, avoid storing them in direct sunlight or near oil stains. Using a simple tire rack or leaning them against a wall is safer. This not only extends the tire's lifespan but also saves you the hassle of readjusting them when you use them next time. The same principle applies to spare tires—storing them vertically prevents pressure-induced air leaks or rubber aging, especially during long winter storage in northern regions when changing tires.
