What Do 165/70 R14 Tires Mean? | JWHEEL

What do 165/70 R14 tires mean? "165" means the width of the tire is 165mm. "70" means that the percentage of the section height and width of the tire is 70%, that is, the aspect ratio of the tire. "r" stands for the word RADIAL, which means it is a radial tire. "14" means the diameter of the rim is 14 inches. JWHEEL small wheel are affordable. Small wheel are not easy to bulge. Thicker tires have a higher cushioning capacity for shocks, so they are not prone to damage and bulge when encountering large shocks. Smaller wheels are more comfortable. Thicker tires are better at isolating noise and vibration from the road, less likely to cause road noise and bumps, and higher comfort.

The size of the contact area between the tire and the ground is the tread width. Car owners cannot blindly pursue a larger tread width when replacing or modifying tires. The wider the tire, the larger the contact area. The advantage is that you will feel that the car is more stable to drive, and the improved grip will make you more calm when cornering and braking. The disadvantage is that the rolling assist also increases, resulting in higher fuel consumption of the car. In addition, the wider tread will produce more tire noise when the tire touches the ground. The lower the number, the smaller the tread width. The reduction of the contact area will naturally bring advantages, the friction force will be reduced, and the fuel consumption and tire noise will also be reduced. The downside is that the car's grip becomes poor, and the driver and occupant will feel unsteady, especially during high-speed cornering.

The aspect ratio is also the aspect ratio, which is simply the aspect ratio of the tire. Similarly, the flat ratio can not blindly pursue high or low. For comfort and fuel economy, choose a high aspect ratio. If you want to improve the visual effect, class and handling performance, then choose a low aspect ratio. Pay attention to the use of high-flat ratio tires, and slow down when turning, otherwise the body will easily roll. Pay attention to the use of low-profile tires, and slow down when passing speed bumps or potholes, otherwise the tire sidewall will easily bulge.

The size of the hub is the diameter of the hub, and the diameter of the hub is equally important, so you must not choose it casually. Large-diameter wheels with better handling properties are suitable for sports cars and racing cars, so sports cars can also choose it. Smaller diameter wheels with better comfort, lower fuel consumption and better value for money are suitable for family cars.

In simple terms, the load index is the maximum weight that the tire can bear under a certain tire pressure, so the owner of the car should not exceed the load corresponding to the index, otherwise there will be potential safety hazards.

The certified speed rating of a tire within a certain speed is the speed rating. Speed class letters are J, K, L, M, N, P, Q, R, S, T, U, H, V, W, Y, ZR, where J-Y represents 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, 200, 210, 240, 270, 300 km/h, while ZR stands for 240 km/h. The further back the speed class letter is, the faster the tires run. So the speed level is the same as the load index, you can't exceed them, otherwise there will be safety hazards.
