Should all four tires be consistent when picking up the car?
2 Answers
All four tires should be consistent when picking up the car. The purchased tires should match the original car tires: The specifications of the purchased tires should be consistent with the original tires equipped on the car. The same car should be equipped with the same specifications: The same axle should be equipped with tires of the same specifications, structure, manufacturer, and tread pattern (load index and speed rating should be consistent). The replacement tire load index should be greater than or equal to the original tire: The load index of the replacement tire must be greater than or equal to that of the original tire, and the speed rating of the replacement tire must be greater than or equal to that of the original tire.
It's crucial that all tires are completely identical when taking delivery of a new car. Manufacturers ensure that all four tires have uniform specifications, tread patterns, and brands when leaving the factory. If you notice any tire that differs or shows signs of repair, you must raise the issue immediately. An old friend of mine working in 4S店 after-sales has seen too many disputes, including a batch of cars where spare tires were swapped during transportation, and customers only discovered high-speed steering wobbles after six months. Tires are like shoes for humans - inconsistent sizes and tread patterns can lead to differences in friction coefficients, and uneven water drainage in rainy conditions can easily cause skidding. Remember to check whether the brand model codes and DOT date numbers on the tire sidewalls are identical across all four wheels.
