What is the difference between 120 tires and 130 tires?

[DelAdeline]

The main difference lies in the section width. A 120 tire has a section width of 120mm, while a 130 tire has a section width of 130mm. This type of tire specification is commonly used for motorcycles. Below is a detailed introduction to tire specifications: Specification model representation: Tires come in many specification models, and different specification models are suitable for different types of vehicles. The specification model identification is usually found on the sidewall of the tire, represented by a series of alphanumeric characters, corresponding to the tire's tread width, aspect ratio, type, rim size, load index, and speed rating. Speed rating: Based on the maximum speed they can withstand, tires can be divided into different speed ratings from A to Z, with the A rating further subdivided into eight different levels from A1 to A8. The further back the letter representing the tire's speed rating is in the alphabet, the better the tire's performance.
