Tire Rotation:

Tires should be rotated every six months or 6,000 to 8,000 miles. (2300 英裏太勤了，沒必要)

4-wheel alignment:

For most cars, there are no specific requirements. Your mechanic would typically recommend doing the wheel alignment every two-three years or if there are signs that the alignment is off. Often, the wheel alignment is recommended when new tires are installed.

四輪定位 (4-wheel alignment) 不當的症狀是什麽？
– 直行時方向盤偏離中心
– 在平直的道路上行駛時，車輛向一側拉
– 車輛的行駛狀況不佳，感覺不穩定，左右搖擺
– 轉向時輪胎在尖叫
– 輪胎磨損不均勻
