Must the tire specifications be consistent when replacing tires?

[DeJulia]

Replacing tires requires consistent specifications. If the specifications differ, the tire radius will vary, resulting in different distances traveled per rotation and causing inaccurate odometer readings. However, temporary substitution is acceptable. Tire Specification Introduction: Tire specifications are commonly represented by a set of numbers. The first number indicates the tire section width, and the latter denotes the rim diameter, measured in inches. For example, a tire marked 19560R14 represents a width of 195mm, an aspect ratio of 60, and a diameter of 14 inches. Tire Classification: Tires are categorized by usage, including load-bearing tires, passenger vehicle tires, and mining tires, among others. Load-bearing tires must indicate the ply rating in addition to the specification dimensions marked on the sidewall. However, it is important to note that the ply rating of load-bearing tires does not refer to the actual number of layers but rather to the load-bearing performance equivalent to that of tires made with cotton cord layers, using high-strength material cords for the tire body.
