4S stores themselves require significant capital investment, which makes tire prices higher compared to ordinary auto parts markets or repair shops. Here is an introduction to automotive tire-related content: 1. Cushioning Impact: Automotive tires are one of the important components of a car, directly in contact with the road surface, and together with the car suspension, they cushion the impact received during driving. 2. Comfort: Ensuring the car has good ride comfort and smooth driving, ensuring good adhesion between the wheels and the road surface, improving the car's traction, braking, and off-road capability, and bearing the weight of the car.

Last time I was also shocked by the price when changing tires at the 4S shop. The mechanic explained that the high cost comes down to three points: First, the original factory-certified tread compound is specially formulated to match the vehicle's suspension system, offering better grip and noise control compared to generic tires on the market. Second, the accompanying electronic alignment equipment can fine-tune the camber angle to one-thousandth of a degree, a precision unattainable with ordinary shops' mechanical alignment racks. Third, they always perform dynamic balancing plus four-wheel alignment during tire changes, with equipment calibration alone taking over forty minutes. After the tire change on my SUV, the steering wheel vibration disappeared, and it feels rock-solid on the highway, as if glued to the road. This precision service is truly worth the price.

With over a decade of experience in auto repair, I've figured out the tricks. The high tire prices at 4S shops come from their 'all-inclusive' service. Look, they always check suspension bushing wear before tire replacement and reprogram the TPMS sensors. After installation, they even top up nitrogen for free and offer free wheel alignment correction if uneven wear occurs within six months. Last week while fixing a client's steering pull issue, I discovered that although the tires replaced at a chain store were 300 yuan cheaper, they failed to detect slight wheel rim deformation, which ultimately cost the client an extra 700 yuan for bearing replacement!

Comparing the bills for three tires revealed some tricks: the 4S shop's quote included 48 standard inspections, such as tire removal and installation with anti-scratch wheel hub coating, and wheel bolts tightened in three stages to factory torque specifications. Chain stores skipped these steps, hence the lower price, but a friend once experienced a dangerous situation with loose bolts on the highway. Now I understand—what you're paying for is that ISO-compliant process, where even tightening a screw requires an electronic torque wrench beeping to confirm it's done right.
