The difference between tires 97h and 97v is that 97h indicates the load index and speed rating of the tire, while 97v represents the load index and speed rating of the vehicle tire respectively. Below is relevant information about tire specifications: Tire specifications are commonly represented by a set of numbers. The first number indicates the tire section width, and the second number represents the rim diameter in inches. For example, 165/70R14 means a radial tire with a section width of 165 millimeters, an aspect ratio of 70, and a rim diameter of 14 inches. Some tires may also include other letters or symbols with special meanings: "X" indicates a high-pressure tire; "C" indicates a reinforced type; "B" indicates a bias-ply tire; "-" indicates a low-pressure tire. M and S are abbreviations for Mud and Snow in English, indicating that the tire is suitable for use on snowy and muddy roads. Tire model numbers are mostly marked as follows: 215/70R15. The meanings of these numbers are: 215 represents the tire section width in millimeters; 70 is the aspect ratio, which is the ratio of the tire sidewall height to the tire section width, with 70 representing 70%; R is the abbreviation for Radial, indicating that the tire has a radial structure; 15 is the outer diameter of the rim in inches.

The main difference between 97H and 97V on tires is the speed rating. The number 97 indicates the same load capacity, both capable of carrying approximately 730 kilograms. However, the suffixes H and V determine the maximum speed: H allows up to 210 kilometers per hour, while V can reach 240 kilometers per hour. This means if you enjoy driving fast or frequently use highways, V is more suitable due to its better heat resistance and stability; whereas H is ideal for daily city commuting. Additionally, speeding is unsafe, so when choosing tires, consider your vehicle type and driving habits—don't compromise handling to save a little money. Regularly checking tire pressure and wear is also crucial to avoid blowouts caused by aging or improper use. Safety first!

What to Do When Car Wheels Are Frozen?

Solutions for frozen car wheels: Prepare a large amount of warm water, ensuring the temperature is not too high as excessively hot water can cause significant damage to the car tires. While using warm water, you can also add salt to it, which helps speed up the melting process. Another method is to use a car inverter. Plug the inverter's electrical connector into the cigarette lighter socket, start the car, and once the inverter begins operating, insert a hairdryer into the inverter to melt the ice. It's important to note that when using the hairdryer, avoid continuously blowing air at one spot. Instead, move it in a circular motion to distribute heat evenly and keep it at a safe distance from the ice to prevent water from entering the hairdryer. If the wheel freezing is not severe, you can try starting the car and moving it back and forth. If it doesn't move, then resort to other methods.
