Four-wheel maintenance should be performed after driving a new car for three months, and then every six months or 10,000 kilometers. The main purpose is to check if there are any issues with the four wheels during driving. If no problems are found, the car can continue to operate normally. Four-wheel maintenance includes: Inspecting the wear condition of the four tires, the braking system, and the vehicle's chassis. Four-wheel maintenance can be performed together with regular maintenance to save time. This ensures the vehicle runs smoothly and enhances driving safety. Four-wheel alignment is required in the following situations: After replacing new tires or repairing collision damage; uneven wear on the front or rear tires; heavy or shaky steering wheel while driving; the car pulling to the left or right when driving straight. If the data recommended in the vehicle manual matches the data in the four-wheel alignment system, it can be considered standard.

I've been driving for over ten years, and I usually perform four-wheel maintenance every 15,000 kilometers, mainly focusing on wheel alignment and tire inspection. This includes checking for even wear and proper tire pressure. If you frequently drive on mountain roads or carry heavy loads, it's advisable to shorten the interval to 10,000 kilometers. For city commuting, checking every 20,000 kilometers is also fine. Regular maintenance can prevent uneven tire wear, extend tire life, save fuel, and enhance safety. I remember one time I forgot to do it, and the inner side of the tire was completely worn out, causing scary vibrations at high speeds, which ended up costing me a lot more for replacement tires. So, I recommend combining it with oil changes—it's both convenient and economical. Also, pay attention to whether the steering wheel pulls to one side during normal driving, and inspect the tires promptly after driving on bumpy roads.

As a car enthusiast, I believe four-wheel maintenance is crucial for enhancing driving pleasure. Generally, it's recommended to perform wheel alignment and tire balancing every 20,000 kilometers. But for someone like me who frequently speeds or races on tracks, I need to check every 15,000 kilometers. Good tires make handling more precise and braking more reliable. Neglecting them can lead to sluggish steering, instability at high speeds, or even excessive tire wear affecting braking performance. I also combine checks for tread depth and tire pressure to ensure the car remains rock-solid under extreme conditions. I remember once delaying maintenance, and the tires vibrated noticeably during mountain road turns—costing me extra money for repairs afterward. Regular maintenance is the foundation of car enjoyment, keeping your beloved vehicle in top condition for a more thrilling and safer drive.

When traveling with children, safety is the top priority, so I schedule a four-wheel maintenance check every 18,000 kilometers. The process is simple: checking wheel alignment and tire wear to ensure the car drives straight without deviation. If there are many gravel roads or rainy/snowy conditions, I add an extra check at 10,000 kilometers to avoid sudden loss of control risks. Neglecting maintenance can easily lead to uneven tire wear, and unstable tire pressure may affect braking, especially dangerous on highways. My neighbor once experienced a tire blowout accident due to poor maintenance, with unimaginable consequences. Therefore, I’ve made it a habit to include an additional inspection during routine maintenance—it’s both convenient and ensures family safety. The key is to combine it with daily driving habits—smooth driving can extend intervals, while avoiding aggressive maneuvers is crucial.
