What should be noted when changing wheels?

Here are the precautions for changing car tires: Choose the appropriate tires: The specifications of the tires should be the same as the previous ones and must match the other tire on the same axle. Replace the valve stem as well: After changing the tires, the aging cycles of the new tires and the old valve stems differ. During the new tire's cycle, the valve stem may develop issues. The installation direction should align the arrow on the inflated wheel with the direction of the car's forward movement. When inflating, you can fill to the maximum pressure allowed by the tire and then reduce it to the manufacturer's standard pressure. Installation of new tires: New tires are best installed on the rear axle of the vehicle. If more worn tires are placed on the rear axle, it can reduce the rear wheels' water drainage capability, thereby increasing the risk of driving in rainy conditions. Therefore, if only two new tires are installed, they should be placed on the rear wheels.
When changing wheels, I focus on safety issues. The wheel size must match the original vehicle specifications. If it's too large, it may affect brake clearance, and if it's too small, the tire won't fit, both of which could lead to brake failure or accidents. The bolt hole pattern and offset value must also be checked. If these are incorrect, they could rub against the suspension system, directly threatening driving safety. Additionally, pay attention to the wheel's load index and speed rating. Don't opt for cheaper wheels that don't meet standards, as they could be dangerous when carrying heavy loads or driving at high speeds. After the modification, it's essential to perform a four-wheel alignment and dynamic balancing to avoid shaking and wobbling during driving, which increases the risk of accidents. It's recommended to choose products from reputable brands and not to overlook these details for the sake of speed or convenience.
As an experienced car owner, I prioritize the performance impact when changing wheels. Switching from smaller to significantly larger wheels can slow down acceleration, increase fuel consumption, and worsen handling; conversely, smaller wheels may feel lighter but reduce comfort. Incorrect offset (ET value) can make steering overly heavy or light, and in extreme cases, cause brake disc rubbing, affecting braking performance. Material-wise, I prefer lightweight alloys to reduce unsprung weight and improve cornering agility, though steel wheels are more durable and better suited for rough roads. Before making changes, calculate the overall impact on fuel efficiency and power response—balancing aesthetics and practicality is key.
