91h on car tires refers to the load index of the tire. The number 91 corresponds to a load capacity of 615 kilograms per tire, and the letter h represents the speed rating, with h indicating a maximum speed of 210 kilometers per hour. Precautions for replacing car tires include: 1. Check the expiration date; inventory should not exceed 3 years; 2. Observe the tread pattern and color; 3. Inspect whether the joint between the tread and sidewall is smooth; 4. Avoid mixing tires of different structures and sizes. Tires are one of the critical components of a car, directly contacting the road surface and working with the car's suspension to mitigate impacts during driving. Their functions include: 1. Ensuring good ride comfort and smooth driving; 2. Ensuring excellent adhesion between the wheels and the road; 3. Improving the car's traction, braking, and off-road capability; 4. Supporting the weight of the car.
