Can a Spare Tire Still Be Used After 6 Years?

[TimothyDella]

Under normal circumstances, a spare tire stored in the trunk for 6 years can be used for emergency purposes, but it should be replaced with a regular tire immediately after emergency use. Below is some information about tires: 1. The main functions of a tire include dry traction, hydroplaning resistance, providing comfort, reducing driving noise, impact resistance, wet traction, load capacity, handling performance, average wear, and mileage. 2. The cross-sectional structure of a tire can generally be divided into 4 parts: tread, shoulder, sidewall, and bead. Each part has its own function. 3. The tread mainly contacts the ground, the shoulder and sidewall provide support, and the bead contacts the wheel rim to provide sealing.
