Is it necessary to retorque lug nuts after tire change?
Yes, it is often recommended to retorque lug nuts after a tire change. This practice ensures that the lug nuts remain properly tightened after the initial settling period. When wheels are installed, the lug nuts might loosen slightly due to vibrations and the seating of the wheel against the hub. Retorquing the lug nuts after driving a short distance (typically around 50 to 100 miles) helps maintain the correct torque and ensures the wheels are securely attached, reducing the risk of them coming loose while driving. Always follow the vehicle manufacturer's guidelines and torque specifications.
以前在其他车铺换完胎balance了就拉倒。现在在costco换，receipt上要求开几十迈以后回来retorque.我自己在家做一下就完了。我的理解是retorque 是个good practice，有助于tire balance, Costco 可能也防止万一开始没上紧出问题吃官司。为什么其他店没要求？
Costco轮胎质量和价钱都还不错，有road hazards insurance。不过我现在放弃在他们那里补胎了，太麻烦了。上次新胎刚换个把月就扎个钉子，去找他们，特别忙当天没有walk-in的，我要把车留下来让他们第二天有空再修也不行，不让把车留在停车场过夜，预约就要好几天，离家又远。下次不在那里搞了，除非胎废了找他们要warranty.
我的02 Camry和07 Infiniti G35都要求600迈之后retorque. 我的经验是几十迈之后有的会松掉十几度。
网上有时有轮子飞出的新闻。如果Costco服务的车出事，那要不少银子来摆平的。顾客也愿意。
我的新rotor 就是让tire plus 拧过紧给拧曲掉了，换上才开了两三千迈去换胎回来我照常check 他们有没给拧过站，结果我要接上一根一米多的铁管才能拧松！转了转轱辘rotor 就有时松时紧的阻力。
轮子装上后会忪掉是因为靠固紧件连接的任何两个物件在震动时都会相对位移，程度多少而已，位移大了就松了。
达到稳定状态固定住了就不会再变了，除非有外力破坏了这个状态。
还有福特为啥在电马头一万迈的保养要求检查suspension 螺丝有没松动？
静止时的配合和震动时的配合完全是两回事，装沙袋的时候为啥要抖抖？
对此话题我的兴趣到此为止。
不拧这一次，大概率没问题，小概率您自己兜着，心诚则灵，自己看着办呗。
那你就又多了一个半小时的Costco 购物的时间，后果你懂的。
能有谁比设计制造你的车的人更知道你的车要咋保养？

Do people actually go back to the shop to get this done? If they need to be re-torqued after 100km, why not every 100km thereafter?
