As you all know, the tires of the car are the most worn parts of the car, and they also need to be replaced and maintained regularly. after all, the tires bear the weight of the car, and they are also in direct contact with the ground below, which is the communicator of power. so wear is also normal, so tires need to be reversed regularly to maintain the wear degree of tires and reduce the probability of accidents while driving. My car changed the tire in October last year. It has been a year now and has traveled 18000 kilometers. It is time to change the position of the tire. I didn’t take the time to go to the repair shop to do tire maintenance for my old Xuan wing. Strong engine compartment cleaning a series of sanitary activities.The unknown wing of Lao Xuan is quietly waiting for inspection.Sexy little butt that’s a little dirty. Go and give her a bath when you’re done.The kind-hearted Nissan logo is still bright after ten years.Check the tires and find that the wear is uneven, the tires of Flying feet are fat, silly and cute.Check the tread to see if there are any pebbles in the tires.The Little Flying foot of 19560R16 89H runs more than 18000 kilometers a year. The overall feeling is OK.This is me rubbing against the kerb, the road in the community is too narrow, two cars can not break the road, only with the help of the roadside kerbstone. Looked at the tire rub problem is not big, the heart felt relieved.The material of this tire is quite exquisite, and none of these small rubber spots have been worn out.Get to work, unload. Unload. Unload.This time the tire is a common pattern, if it is a radial tire, it can only be reversed forward and backward, not cross-replaced, and if it is an ordinary pattern, it can be cross-replaced, and the drive wheel should be changed directly, and the non-drive wheel should be crossed. Of course, if you can’t, you can also go to a special person for help. After all, it is best to do a dynamic balance check after replacement, so that the car will be more stable.This is the tool of dynamic balance.First of all, install the unloaded tire on the dynamic balancing machine and fix it.The mechanic was so serious that he picked out all the pebbles in the tires.This time my car has cross wheels, that is, the left front tire reverses to the right rear tire, and the right front tire reverses to the left rear tire. One by one. Take your time.A polished brake disc.The tires are being balanced.As long as the two scarlet letters are the same or zero, it looks simple, but the actual operation is a bit cumbersome, but fortunately, I only take pictures, and the mechanic will unload the tires in an orderly manner-do dynamic balance, debug correctly, and then cross-install the tires.This display is normal.The mechanic disassembles the car in turn, balances it, and installs it diagonally. When putting on the tire screw, the four nuts should also be in order, which should be first down, then up, then left and then right, so that it is faster and safer.If there is an air conditioner, loading and unloading screws is fast.Continue to balance the tiresThis is the left front wheel installed.Installation of right rear wheel is completeThe installation of the left rear wheel is complete, and the installation is finished in turn.Start checking tire pressure.This electronic tire pressure instrument shows 2.11, but how can my digital manual manometer be 2.4? There seems to be an error.Each tire is inflated to a moderate degree to ensure a long-distance ride during the holidays.The mechanic is full of gas according to the standard.Start checking brake oil.Finally, use a Phillips wrench to reinforce the screws one by one.After the car came out, the mechanic specially cleaned the air conditioner for me.All of a sudden, the dust is flying.Open the four doors and let the dust fly away.The mechanic cleaned my engine compartment by the way.Blow, blow. Blow… Keep blowing until it’s clean.After half an hour, the dust is gone with the wind, I am also ready to give Lao Xuan wing a bath, let’s go!Look up at the blue sky and white clouds, the empty sky.Now after environmental protection, there has been a long-lost blue sky in the city.In fact, the car is for us, but also a member of our family, as long as you check on time, regular maintenance, in addition to problems timely repair on the line. I am looking for a medium-sized shop that is familiar with car repair and maintenance, and we can discuss if there is a problem. Just do your best on both sides! The post is over, thank you for watching.
