What does 101w mean on a tire?
2 Answers
Tire 101w refers to a maximum load capacity of 825kg, where 'w' indicates a speed rating of 270km/h. Below are specific details about car tire specifications: 1. Specification model representation: Tires are crucial components of a vehicle, with various specification models designed for different types of vehicles. These specifications are typically marked on the sidewall of the tire as a series of alphanumeric characters, representing the tire's tread width, aspect ratio, type, rim size, load index, and speed rating. 2. Speed rating: Based on the maximum speed they can sustain, tires are categorized into different speed ratings from A to Z, with the A category further divided into eight levels from A1 to A8. The further the letter representing the speed rating is in the alphabet, the better the tire's performance.
The 101W marking on the tire is a combination of the load index and speed rating. The number 101 indicates the maximum load capacity per tire, approximately 825 kilograms, so if your vehicle's total weight when fully loaded approaches this value, you need to ensure the tires meet the specifications. The letter W is the speed rating, meaning the tire can safely operate at speeds up to 270 km/h, suitable for some performance vehicles. When replacing tires, you must match the original manufacturer's recommended specifications, otherwise overloading or high-speed driving may cause the tires to overheat, bulge, or even blow out, affecting driving safety. It's best to glance at the sidewall symbols before driving to confirm they are not worn or damaged. In daily maintenance, I've also found that many car owners overlook this detail, so I always remind them to perform regular tire checks—after all, safety comes first. When purchasing new tires, checking the manual or verifying in the store can avoid a lot of trouble.
