How to Inflate a Spare Tire?
2 Answers
Generally, the spare tire should be inflated using the onboard air pump. Open the left partition of the trunk, take out the spare tire and the accompanying tools beneath it. Locate a gray air pump approximately 20 cm in length and width, connect the air pump's nozzle tube to the spare tire, plug the power cord into the cigarette lighter socket, and turn on the air pump switch to inflate the spare tire. Maintain a pressure of 2.2-2.4 bar, which is normal for tires. The maintenance methods for a car's spare tire are as follows: 1. Regularly check the air pressure of the spare tire to prevent leaks and other issues. 2. Pay close attention to the usage period of the spare tire, which is generally four years. However, this should also be judged based on the tire's aging condition. If cracks or significant wear appear, it should be replaced promptly. 3. Be mindful of the spare tire's storage location. Typically, the spare tire is stored in the lower compartment of the trunk, but with the increasing variety of car models, there are also hanging spare tires. Hanging spare tires are usually located under the car's chassis. Over time, the spare tire may come into contact with various harmful substances on the road. If the hanging tire is not protected, these substances can corrode the tire.
Before inflating the spare tire, first locate its position. In most vehicles, it's hidden beneath the trunk floor panel. Lift the cover to reveal the folded jack and air pump. Connect the air pump to the cigarette lighter power source or its built-in battery, then securely screw the air hose onto the spare tire's valve stem. Gradually inflate while monitoring the pressure gauge - standard car tire pressure is typically 2.3-2.5 bar, with exact specifications labeled on the door B-pillar sticker. Pump in multiple short bursts, constantly checking the gauge to prevent overinflation. After inflation, shake the pump a few times to dissipate heat as the rubber hose gets extremely hot. If the spare tire shows rubber cracks or valve leakage, it's essentially unusable and requires replacement. Never use a temporary spare tire for long-distance travel - its worn tread pattern provides inadequate braking performance.
