What does 105V tire mean?
1 Answers
The 105 in tire 105V indicates the load index, meaning each tire can carry a load of 925KG, and the V indicates the maximum speed of the tire is 240 km/h. The load index of a tire refers to the maximum load capacity the tire can bear when inflated to the specified pressure, while the speed rating of a tire refers to the maximum speed at which the tire is allowed to travel, generally represented by uppercase English letters and marked on the side of the tire. The maximum load capacity does not mean the tire will immediately fail if it exceeds this limit, but prolonged operation is not allowed. Prolonged operation will generate more heat, ultimately leading to tire fatigue damage, reduced lifespan, or even structural failure causing a blowout. Different letters represent different speed ratings. For example, "L" indicates a maximum allowable speed of 120 km/h, "T" represents 190 km/h, "V" stands for 240 km/h, and so on. Generally, higher-end cars use tires with higher speed ratings. However, the speed rating of a tire will decrease over time due to aging and reduced elasticity, and tire pressure also affects the speed rating—lower pressure leads to a lower speed rating. In daily use, pay attention to the following points regarding tires: Regularly check the tire surface for cracks, deformations, or other defects. Due to wear from driving, the tread grooves gradually become shallower. If the tread is worn flat, it loses its drainage and anti-slip functions, significantly reducing the car's performance. Small cracks may seem minor but can be a hidden danger for blowouts at high speeds. Additionally, promptly remove small stones stuck in the grooves. Try to park on flat ground. Avoid parking on roads with thick, sharp, or pointed stones. Do not park near or in contact with petroleum products, acids, or other materials that may deteriorate rubber. After parking, the driver should not turn the steering wheel, as this accelerates tire wear. Do not splash water for cooling. In hot weather or during high-speed driving, tires can overheat, and pressure may increase. In such cases, stop to allow the tires to cool naturally. Never release air to reduce pressure or splash water to cool them, as this may cause abnormal aging of the tread rubber. Avoid sudden braking. Try to minimize frequent or hard braking to prevent accelerated tread wear from dragging against the road.
