Is It Safe to Use a Spare Tire on the Highway?
1 Answers
It is possible to drive on the highway with a spare tire, but non-full-size spare tires should not exceed 80 km/h. Here is some extended knowledge about spare tires: 1. Definition of a Spare Tire: A "spare tire" is essentially a backup tire prepared for a car. In case of a flat tire or other issues with a wheel, the spare tire can promptly replace it, preventing the car from breaking down midway. 2. Spare Tires Should Not Be Used in Tire Rotation: Tire shops have strict requirements for tire rotation, and spare tires are particularly unsuitable for this purpose. Tire rotation is meant to balance wear on different parts of the tire, and it is no longer recommended to rotate tires left and right. Front-to-back rotation also presents issues with uneven wear. Since spare tires have different wear patterns, using them in rotation increases safety risks. 3. Spare Tires Are Not for Long-Term Use and Pose Safety Risks: Spare tires are intended for emergency use only, not for long-term driving. Regardless of their width, manufacturers have specific production and usage requirements for spare tires. Because spare tires are not regularly used on the car and thus have no wear, a brand-new tire behaves differently from a heavily worn one. Using a spare tire on the car inherently carries certain safety risks.
