Tire load capacity refers to the maximum weight a tire can safely support when properly inflated. This capacity is crucial for vehicle safety and performance, as exceeding it can lead to tire failure, reduced handling, and increased wear. Each tire has a specific load rating, which is usually indicated on the sidewall of the tire, often represented by a number and letter code. To determine the total load capacity for a vehicle, you should consider the load ratings of all tires and the vehicle's specifications. It's important to ensure that the combined weight of the vehicle and its cargo does not exceed the total load capacity, as this can affect the vehicle's stability and safety on the road.
