What is the difference between single-ply and double-ply tire sidewalls?
1 Answers
Tire sidewalls with single-ply and double-ply differ in the following ways: Single-ply sidewalls are softer in hardness, have lower toughness, but feature thicker cords and lighter weight. Double-ply sidewalls offer higher hardness, greater strength, and enhanced toughness, but with reduced comfort. Tires are typically mounted on metal rims to support the vehicle body, absorb external shocks, maintain contact with the road surface, and ensure driving performance. Tires operate under complex and demanding conditions, enduring various deformations, loads, forces, and extreme temperatures during use. Therefore, they must possess high load-bearing capacity, traction performance, and cushioning properties, along with excellent wear resistance, flex resistance, and low rolling resistance with minimal heat generation.
