What Issues Should Be Noted When Replacing Tires?
5 Answers
Issues to be noted when replacing tires are: 1. After installing new tires or performing tire disassembly and assembly, dynamic balancing is required; 2. When replacing new tires, new valve stems should also be installed, as valve stems are rubber products and may deteriorate over time; 3. Check tire pressure to avoid overinflation or underinflation; 4. Perform a four-wheel alignment when installing new tires. Tire maintenance precautions: 1. Underinflation or overinflation can cause abnormal tire wear, shorten tire lifespan, and increase fuel consumption; 2. Tire pressure checks should be conducted when the tires are in a cooled state, using a tire pressure gauge or a tire pressure monitoring system; 4. The standard tire pressure is approximately 2.2 to 2.6 bar, neither too high nor too low.
When working in a repair shop, changing tires may seem simple but requires attention to multiple details. First, ensure the vehicle is parked on level ground, the parking brake is engaged, and the transmission is in gear to prevent rolling hazards. Use a jack to support the designated points on the vehicle frame—avoid incorrect placement to prevent chassis damage. When loosening lug nuts, do so diagonally to maintain even pressure and prevent warping. Check that the new tire specifications match the original, including size, load index, and speed rating, as mismatches can affect handling and safety. After installing the new tire, tighten the lug nuts to the specified torque, typically in two to three diagonal passes. Don’t forget to perform a dynamic balance test to eliminate tire vibration issues. Weather conditions also matter—exercise extra caution when working on wet or slippery surfaces. Finally, test-drive to ensure no abnormal noise or vibration. Regular tire wear inspections are recommended for proactive replacement and peace of mind.
As a safety-first veteran driver, I prioritize hazard prevention when changing tires. After parking the car securely, turn off the engine and wear gloves and goggles to protect yourself. Use the proper jack and backup tools—never risk using bare hands. Loosen the lug nuts and remove the tire slowly to prevent reactive force from injuring your arms. After installing the new tire, always confirm the tire pressure is correct before driving—both overinflation and underinflation affect fuel efficiency and the risk of a blowout. During rainy weather or at night, it’s best to seek assistance or move to a safer location for the task—working alone is hazardous. Replace old tires promptly, as reduced grip increases accident risks. I also recommend checking tread depth every 10,000 kilometers—don’t delay if it’s too worn. Safety is no trivial matter—this habit ensures more confident driving.
When I first started learning to drive, changing tires made me nervous. First, prepare the basic tools: a jack, wrench, and spare tire gloves. It's important to find an open space to park—don't do it on the roadside emergency lane. Before loosening the screws, take a photo to remember the order, and operate diagonally to avoid twisting them randomly. When installing a new tire, clean the rust stains on the wheel hub to ensure a smooth contact surface. Don't cheap out by buying tires of different brands—consistent size and tread pattern are essential for stable driving. Test the tire pressure for about 30 minutes and adjust it according to the value on the car door label. A common mistake beginners make is either not tightening the screws enough or over-tightening them—using a torque wrench for calibration is more reliable. After changing the tire, drive a short distance and check the dashboard for any warning lights. With practice, you'll get the hang of it and won't be afraid anymore.
From a cost-saving perspective, I consider more details when changing tires. First, evaluate the condition of the old tires—if the center wears out quickly, balance the wheels; otherwise, directly purchase new tires matching the original specifications, avoiding mixing different models for convenience as it affects lifespan. In terms of price, economy tires are durable and easy to maintain but have poorer grip. The right time to replace is when tread depth falls below 1.6mm or there are multiple sidewall cracks—replace early to avoid emergency braking accidents. Used tools can be used during the job, but ensure reliable vehicle support. Pay attention to even torque when tightening screws to avoid wasting effort on repeated adjustments. After replacement, check tire pressure monthly to extend usage. This approach ensures both safety and cost-efficiency.
