How many kilometers can a compact spare tire generally be used for?
1 Answers
Compact spare tires are designed for temporary use with a maximum speed limit of 80 km/h and a recommended travel distance not exceeding 100 kilometers. A compact spare tire is smaller in diameter and narrower in width compared to the regular tires. It differs from the vehicle's four main tires in speed rating and load index, thus cannot serve as a permanent replacement. When driving with a compact spare tire installed, speed restrictions must be strictly observed. Due to specification differences from original tires, compact spares carry explicit speed limit markings (typically 80 km/h). Drivers must adhere to this limit for safety. On highways, always use the rightmost slow lane with hazard lights activated. Compact spares should be mounted on the front axle. Since higher-speed-rated tires are normally installed on the rear axle to prevent potential oversteer (commonly known as "tail swing"), the lower-speed-rated spare belongs on the front axle. Prolonged use of compact spare tires is prohibited. Significant performance differences from original tires may adversely affect braking efficiency and handling stability, compromising driving safety.
