What does 225/45r1791w mean?
1 Answers
It refers to tire specifications, where 91W indicates the load index and speed rating, 225 is the tire section width, 45 represents the aspect ratio, and 18 denotes the inner diameter size. 91 stands for the load index, and W is the speed rating. Below is relevant information about tires: 1. Tire Introduction: Tires are the only components of a car that come into contact with the ground. Some car owners only replace the tires on the drive wheels when changing tires. For example, some front-wheel-drive car owners may only replace the two front tires, while some rear-wheel-drive car owners may only replace the two rear tires. In fact, this practice is acceptable. 2. Tire Aging: Tires are made of rubber and will age over time. It is recommended that car owners replace their tires every four years, even if the mileage is low within those four years. This is because tires can also age when left unused for extended periods, so it's important to check the production date when purchasing new tires.
