What are the precautions for changing tires?
2 Answers
Precautions for changing tires: 1. When replacing, choose tires with the same specifications as the original vehicle assembly; 2. Replace two tires at the same time, and after replacement, each wheel must be rebalanced to ensure the mass distribution of the entire assembly is very uniform; 3. After changing tires, the aging cycles of the new tires and the valve stems differ, and valve stem issues may arise and are not easily detected. It is recommended to replace the valve stems when changing tires; 4. If using the original vehicle tires, follow the manufacturer's installation requirements. For non-original tires, the side with the production date should generally face outward.
Buddy, changing tires isn't as simple as just loosening the bolts. Last time I helped a friend change tires and almost had an accident, so I've summarized some hard-earned lessons: First, park on level ground with the handbrake on, automatic transmissions should be in P for extra stability, and wedge a rock against the wheels. Second, mark the jack position with a pen before lifting – only the chassis frame rails should bear the weight, or you'll dent the body panels. Third, loosen/tighten nuts in a crisscross star pattern, like rotating skewers on a BBQ to distribute force evenly. Most crucially, don't race off afterward – new tires have slippery release compound; my neighbor sideswiped a wall cornering too soon. Always check the DOT date code (e.g., 0719 in oval means 7th week of 2019) – reject any tires over 6 years old even if free! 160 chars
