The tire load rating is engraved on the side of the tire, indicating the maximum load capacity of the tire. For driving safety, this load limit should not be exceeded. For example: In the tire specification 195/65R15 91V, the load index is 91, which corresponds to a maximum tire load capacity of 615 kilograms. The tire load rating indicates the maximum weight the tire can bear under normal inflation conditions, that is, the numerical value representing the maximum load a single tire can carry under specified conditions with proper air pressure. The speed rating is indicated by a letter, ranging from J to Z. Under the corresponding load capacity of the relevant load index, each letter represents the maximum speed allowed for the tire. These two factors together are referred to as the service description.

I remember paying special attention to the load rating of my car tires, which is indicated on the sidewall. You'll see a combination of numbers and letters, like 225/55R17 98H, where 98 is the load index. Each number corresponds to the maximum weight the tire can bear, for example, 98 represents approximately 750 kilograms. Never underestimate this data—my old SUV once had tire deformation on the highway due to insufficient load capacity. Later, at the repair shop, I learned how crucial it is to match the tires to the vehicle type, as SUVs typically require higher load indices than sedans. During routine maintenance, I make it a habit to crouch down and check the sidewall markings to ensure the values meet the standard, giving me peace of mind while driving and avoiding the risks of overloading.

I noticed that the load rating of the tire is clearly marked on the sidewall near the edge. That line of code is usually connected to the size and speed rating, for example, 91V is part of the load index 91. A rating of 91 can carry approximately 615 kilograms, and different tire designs vary. When selecting tires, it's essential to match the vehicle manual standards; otherwise, long-term overloading can accelerate tread wear. As a car owner, I glance at that spot during my monthly checks. Maintaining stable tire pressure can extend their lifespan—don't wait until a blowout to regret overlooking these details.

The load rating of a tire is located on the sidewall label, near other specification numbers. It determines how much weight the tire can support, and a low index might cause issues on rough roads. I once saw a neighbor's car experience a tire blowout due to insufficient load capacity, so now when buying a car or replacing tires, I always make sure to check the index value to ensure safety.

Every time I maintain my car tires, I first check the load index in the sidewall code, such as the '94' in 94H, which is the crucial part representing approximately 670 kg of load capacity. It's located on the middle section of the tire's outer sidewall—easy to see yet often overlooked. When selecting new tires, make sure the index matches the original factory specifications, otherwise it may affect handling and stability. I recommend requesting clear photos of the markings when purchasing tires.
