What does 14pr tire mean?

[Ricky]

14pr tire represents 14 ply rating. Below is the relevant introduction about tire ply rating: 1. Introduction: Tire ply rating refers to a specific strength indicator of the maximum load that the tire can bear under actual usage conditions. The tire ply rating does not represent the actual number of fabric layers in the tire. Instead, it indicates that a tire made with high-strength material cords for the carcass has a load-bearing performance equivalent to the number of fabric layers in a tire made with cotton cord for the carcass. 2. Tires with different ply ratings cannot be mixed: Different ply ratings indicate different load-bearing capacities of the tires. Even for tires of the same specification, their load-bearing capacities differ if their ply ratings are different. Therefore, tires with different ply ratings should not be used on the same axle. Otherwise, it could be dangerous when driving at high speeds with a load.
