What is the Difference Between 4-Ply and 6-Ply Tires?

[VanKinsley]

Here are the main differences between 4-ply and 6-ply tires: 1. Ply Rating: 6-ply tires have a higher ply rating than 4-ply tires. The higher the ply rating, the stronger the tire's load-carrying capacity. The ply rating refers to the nominal number of cord layers in the tire's rubber, which may not exactly match the actual number of cord layers, but it is an important indicator of tire strength. 2. Specifications: For both 4-ply and 6-ply tires, the meanings of the letters or symbols in the middle are the same. 'X' denotes high-pressure tires, 'R' and 'Z' denote radial tires, and '-' denotes low-pressure tires. Specifications are the geometric and physical performance data of a tire. Tire specifications are usually represented by a set of numbers, where the first number indicates the tire section width and the second number indicates the rim diameter, both measured in inches.
