The spare tire, as the fifth tire in the car, is always quietly lying in the trunk. Because of this, many car owners often overlook the maintenance of spare tires, and wait until one of the other four tires accidentally occurs. When the spare tire is taken out, it is discovered that the spare tire is not cracked or cracked. Point out the precautions for the maintenance and use of several spare tires.
Maintenance items 1 Always check spare tires
In routine maintenance or before long-distance travel, few vehicle owners test the spare tire, and some unprofessional repair shops often neglect this point. The spare tire inspection is mainly to check the tire pressure and whether there is wear and cracks, and to replace the tire as soon as possible before the tread wears to the wear mark line.
Reminder: If there is a small crack on the side of the tire, you cannot use it to run long distances or high-speed driving, because the tire sidewall is thin, high-speed traffic is prone to puncture.
Matters needing attention 2 Oils and spare tires are not put together
The main component of the tire is rubber, and the rubber is most afraid of all kinds of oil erosion. Owners often store lubricants and other oils in the trunk. Once the tires touch the tires, they will distort the tires, which will greatly reduce the service life of the tires.
Reminder: If the tire is oiled, wash it with a neutral detergent in time.
Maintenance items 3 Spare tire life about 4 years
Many owners think that if the spare tire is left unused in the trunk, it can be “longevityâ€. This is wrong. There are often cases where the owner wants to replace the spare tire after a puncture, but he finds that the spare tire has been severely deteriorated after it has been placed for many years and is already a scrap tire. In fact, because the tire is a rubber product, aging will occur if it is stored for a long time. Generally, the aging period of the tire is about 4 years. Therefore, the spare tire should be replaced after 4 years.
The use of 1 spare tire should not be used for a long time
The spare tire has low frequency of use and less friction with the ground, and some spare tires are smaller in size than the right tire. The flat rate, tire width or tire diameter are different from those of normal tires, so replace the spare tire. After the four tires have different friction coefficients, different ground adhesion, and different air pressure, long-term use will have a certain impact on the vehicle's braking system, steering system, and suspension system, causing hidden dangers to traffic safety, but also to the same direction. Other tires produce uneven friction and so on.
Reminder: Some spare tires use brighter colors. The purpose is to remind the owner to replace the spare tire in time. In addition, when using spare tires, especially small-sized spare tires, pay attention to the control of the vehicle speed. Normally, it should not exceed 80 km/h.
Use matters 2 after repair tires put rear wheels
Some owners will use the repaired tires as spare tires. If these tires are to be used again, they must be placed on non-driven wheels. Generally, the middle-level and lower-level vehicles we drive are front-wheel drive vehicles, and due to the front tires The direction of the car is less easy to control, so the repaired tires should be placed in the rear wheels.
Replace the spare tire five steps
Many drivers only know how to drive. When a problem arises in the vehicle, even the most basic operation of replacing the spare tire is not possible, especially female drivers. In fact, the steps to replace the spare tire are also very simple.
The first step: remove the spare tire. In most cars, the spare tire is placed under the luggage compartment divider.
The second step is to use the jack to slightly support the car, and loosen the wheel's tightening nut before the tire has left the ground.
Step 3: Continue to use the jacks to hold the car and remove the original tires after the tires are completely off the ground.
Step 4: Install the spare wheel and fasten all nuts. Note that tightening should be done in the order of the diagonals so that the bolts will be evenly loaded and the tires will not play when driving.
Step 5: Lower the jack, and the tires will be replaced.
