The time required to replace a tire varies depending on many factors. The following is an introduction from the perspective of professional repair shops and personal replacement:

Replacement at professional repair shops

1. Ordinary family cars: If the repair shop is well-equipped and the technicians are skilled, it usually takes about 15-30 minutes to replace a tire. If four tires are replaced at the same time, it may take 1-2 hours. This includes a series of operations such as lifting the vehicle, removing the old tires, installing new tires, performing tire dynamic balance tests, and installing them back on the vehicle.
2. Large vehicles or special models: Large vehicles such as buses and trucks are difficult to replace due to their large tire size and heavy weight. It takes a long time to replace a tire. It may take 30-60 minutes to replace a tire, and it may take 3-5 hours or even longer to replace all the tires of the vehicle. For some supercars or high-end models, the installation of their tires and wheels may be more complicated, and the precision of the operation is required. The time to replace tires will also be relatively long. Replacing four tires may take 2-3 hours.

Personal replacement

1. Experienced car owners: If the car owner has some experience in car maintenance and has all the tools, it may take 30-60 minutes to replace a tire. However, if there are special circumstances such as the tire is tightly attached to the wheel hub, it may take longer.
2. Inexperienced car owners: For those who have no experience in changing tires, it may take 1-2 hours or even longer to change a tire. Because they need more time to familiarize themselves with the operation steps, they may also encounter various problems during the operation, such as difficult to tighten the bolts, unskilled use of the jack, etc.

The above time is only a rough estimate. The actual time to replace a tire may also be affected by factors such as tire brand, model, vehicle condition, work efficiency of the repair shop or individual, and whether additional inspections and adjustments are required.
