What does 909010 tire mean?

[Natalie]

909010 is an incorrect way to write tire specifications. The correct format is: 90∕90-10. Here's a detailed explanation: 1. 90: Represents the tire width, measured from the sidewalls of the inflated tire, with a width of 90 millimeters. 2. 90: Indicates the aspect ratio (90%), which is the ratio of the tire's height to its width. A higher ratio means a rounder tire, while a lower ratio indicates a flatter tire. 3. 10: Denotes the tire diameter of 10 inches (1 inch = 25.4 millimeters). 4. Tire replacement requirements: The specific tires used for a car should be determined based on the vehicle model. Generally, it is not recommended to use tires of different brands on the same car. There are principles for replacing car tires. It's important to note that tires on the same axle must be of the same brand, primarily for safe driving considerations.
