What should be paid attention to when changing tires?

Precautions for changing tires are as follows: 1. Choose tires with the same specifications as those originally installed on the vehicle. 2. When replacing two tires simultaneously, each wheel must be rebalanced to ensure uniform mass distribution across all parts of the assembly. Below is relevant information: Tires are one of the most important components of a vehicle, and their main functions include: 1. Supporting the entire weight of the vehicle and bearing its load. 2. Transmitting traction and braking torque to ensure adhesion between the wheels and the road surface. 3. Reducing and absorbing vibrations and impacts during driving, preventing severe vibrations and premature damage to vehicle components, adapting to the vehicle's high-speed performance while reducing driving noise, and ensuring safety, handling stability, comfort, and fuel efficiency.
Changing tires is something I often do myself, the key is ensuring safety measures are in place. Park on a flat and solid surface, engage the handbrake firmly, and use rocks or wheel chocks to prevent rolling. Have all the tools ready: place the jack at the designated lifting points on the chassis—don’t jack randomly to avoid body damage. When loosening the old bolts, first turn each one half a turn, then fully unscrew them in a crisscross pattern. When fitting the new tire, align the wheel hub with the axle, hand-tighten all bolts before using a wrench to gradually tighten—don’t over-torque; follow the manual’s specified value, usually around 100 Nm. Checking the new tire’s pressure is crucial—adjust it to the standard value on the door-side label (too high risks blowouts, too low damages wheels). After a short drive, always re-tighten the bolts to prevent loosening accidents. Take your time during the process—step by step for peace of mind, saving plenty on repair costs.
Changing tires yourself can be quite enjoyable, with the key being having the right tools and following the correct steps. Find a parking spot with level ground—avoid mud or slopes. Before jacking up the car, loosen the wheel nuts by one turn, then fully remove them after lifting. When aligning the new tire with the wheel hub, hand-tighten all bolts first to prevent misalignment; then use a wrench to tighten them just enough—over-tightening could strip the threads. Having the right tools makes it easy: a lug wrench, jack, and spare tire are essential. After changing, lower the car and re-tighten the bolts. Take a short test drive to listen for unusual noises, and adjust if needed. Ensure the new tire's pressure is accurate for fuel efficiency and safety. Regular tire maintenance keeps your car running longer and saves money.
