Weight ratings are numerical values that indicate the maximum load a vehicle, tire, or other equipment can safely carry. These ratings help ensure safety and performance by preventing overloading, which can lead to mechanical failure or accidents. Common examples include the Gross Vehicle Weight Rating (GVWR) for vehicles and the Load Index for tires. Understanding weight ratings is crucial for proper usage. Exceeding these limits can cause excessive wear and tear, reduced handling, and increased stopping distances. Always refer to the manufacturer's specifications to determine the appropriate weight ratings for your specific vehicle or equipment.
