Lốp dự phòng để dùng khi xe bi bể bánh. cán đinh, gắn vào chạy tạm về nhà, sau đó đem con lốp đã bi tháo ra đề vá sau đó gắn vô lại.Chứ ít ai dùng lốp dự phòng để xài luôn vĩnh viễn.
Xe chạy 30k km mà chưa đảo lốp là sao ? Thường người ta khuyến cáo chạy cứ 5000 dặm hay 8000km là phải đảo lốp bên trái sang bên phải, rồi sau đó là lốp trước ra lốp sau để lốp mòn đều
Lốp dự phòng chỉ dùng khi cần kíp chứ không nên dùng vĩnh viễn như các lốp gắn theo xe nếu lốp dự phòng là lốp gin theo xe còn nếu lốp dự phòng không phải lốp gin mà là mua loại y chang như 4 lốp đã gắn theo xe thì cứ vô tư mà gắn

Since the spare tire is used so infrequently, carmakers have switched to narrow, compact spares to save space and weight. Of course, a spare tire is a lifesaver when regular tires go pop, but leaving the temporary tire on for longer than the manufacturer recommends invites a host of problems. First, a temporary spare isn't as durable as a normal tire. The real strength of a tire comes from the plies—layers of steel and polyester underneath the rubber—and spares don't have as many plies as regular tires. A typical space-saver spare has only one layer of polyester in the sidewall and two belts of steel with a layer of polyester in the tread—about half as many plies as a normal tire. This greatly limits puncture resistance and cornering ability. In addition, as the name implies, space-saver tires are intended to take up less room in car and crossover trunks so that those trunks can be deeper. For that reason, these tires are narrower and have a smaller contact patch. This reduces the amount of traction for the tire, increasing stopping distances and making handling potentially unpredictable in emergency maneuvers. It also means ABS and traction control aren't as effective at keeping you out of danger. And you're not going to have the same ground clearance. If you're towing a trailer, you'll have to leave it behind—spares have much lower load ratings than regular tires. Long-term use of the spare can cause a serious mechanical issue, too: The smaller-diameter tire can put a lot of stress on your differential.
