Typically, the specification of a passenger car tire is marked as ***/**R***, where all parts are numbers. Taking 185/60R14 as an example: 185 = cross-sectional width of 185 millimeters, 60 = aspect ratio of 60%, R = radial tire construction, 14 = rim diameter of 14 inches. Below are related introductions: 1. Support the full weight of the vehicle, bear the load of the car, and transmit forces and moments in other directions. 2. Transmit traction and braking torque, ensure good adhesion between the wheels and the road surface to improve the car's power performance, braking performance, and passability; together with the car suspension, mitigate the impact during driving and dampen the resulting vibrations. 3. Prevent severe vibrations in car components, adapt to the vehicle's high-speed performance, reduce noise during driving, and ensure driving safety, handling stability, comfort, and fuel economy.

Can You Still Drive with a Damaged Tire?

Whether you can continue driving with a damaged tire depends on the actual condition of the tire. Here are more details about tire damage: 1. Punctured tire: (1) First, check the tire pressure. If there is still sufficient air pressure, you can continue driving, but be sure to keep the speed low—no more than 60 km/h. (2) If the tire remains flat and severely deflated when pressed, you should not continue driving and must replace it with a spare tire. 2. Assess the extent of damage and tire material: A completely blown-out tire cannot be driven on. However, if the vehicle is equipped with run-flat tires and the rim is intact, you can replace it with a spare tire and continue driving.

What is the wheel size of the Baojun 310?

The Baojun 310 is equipped with Linglong brand tires in the specification 165/70R14. At first glance, the 165mm tread width may seem narrow, but this is typical for small cars in its class. It is paired with a 5-spoke aluminum alloy wheel, and the braking system features front disc and rear drum brakes. When replacing the wheel hub, the following parameters should be noted: 1. Center Bore (CB): This refers to the size of the wheel hub's center hole. Although wheel hubs with different center bore sizes from the factory can be installed using adapters, this is not recommended for safety reasons. 2. Pitch Circle Diameter (PCD): For example, a wheel hub with a PCD of 5x120mm means it has 5 lug bolts forming a circle with a diameter of 120mm. This value should also match the factory specifications. 3. Offset (OFFSET): Also known as the ET value, a positive offset means the mounting surface is outside the centerline, while a negative offset means it is inside. Passenger cars generally have a positive offset, and this value significantly affects the vehicle's driving stability and cornering tracking.
