What does 18565r1588h on the tire mean?
1 Answers
185 indicates the tread width of the tire, measured in millimeters. 65 is the aspect ratio, which represents the ratio of the sidewall height to the tread width. R stands for Radial, indicating that the tire has a radial structure. 15 is the outer diameter of the wheel rim, measured in inches. 88 is the load rating, which varies according to different manufacturers' specifications. H denotes the speed rating of the tire, indicating a safe speed limit of up to 210 kilometers per hour. Tire maintenance tips: 1. Check tire pressure: Both underinflation and overinflation can cause abnormal tire wear, shorten the tire's lifespan, increase fuel consumption, and even raise the risk of a blowout. It is recommended to check tire pressure once a month to ensure it is at the correct level. 2. Pay attention to tire wear indicators: The wear indicators are located in the main tread grooves and appear as small rubber bars with a trapezoidal cross-section. When the tread wears down to the level of these indicators, the tire must be replaced. During the rainy season, to prevent the vehicle from slipping on wet roads, the tread depth should be maintained at least 3mm above the wear indicators.
