What should be paid attention to when changing tires?
2 Answers
Precautions for tire replacement: 1. Consistent specifications: The replacement tires should have the same specifications as the original tires installed on the vehicle. 2. Balance: When replacing two tires at the same time, each wheel must be rebalanced after replacement to ensure that the mass of each part of the assembly is very uniform. Tires are one of the most important components of a car, and their main functions include: 1. Support: Supporting the entire weight of the vehicle, bearing the load of the car, transmitting traction and braking torque, and ensuring the adhesion between the wheels and the road surface. 2. Smoothness: Reducing and absorbing vibrations and impacts during driving, preventing severe vibrations and premature damage to car components, adapting to the high-speed performance of the vehicle, reducing driving noise, and ensuring driving safety, handling stability, comfort, and energy-saving economy.
I've been changing tires for over a decade, and safety is the top priority. Always find a flat and secure spot to park—never attempt it on curves or steep slopes where traffic is heavy and dangerous. Once parked, firmly engage the handbrake and shift into first gear or reverse to prevent rolling. Position the jack correctly on the chassis support points, avoiding plastic parts to prevent body damage. Loosen the lug nuts with a socket wrench but don’t remove them entirely; wait until the car is lifted to take the tire off. When installing the new tire, tighten the nuts in a crisscross pattern in two stages: first halfway, then fully after lowering the car to ensure even pressure and avoid warping. After replacement, check if the tire pressure meets standards—overinflation risks blowouts, while underinflation hurts handling. Don’t forget to test warning lights and indicators. Regular pressure and wear checks can reduce replacements. Extra caution in rain—slippery ground increases mishaps. A few minutes’ patience beats taking risks.
