Is the Spare Tire the Same as the Original Tire?
1 Answers
Only full-size spare tires have the exact same specifications and size as the original tires, while non-full-size spare tires and run-flat tires differ from the original tires. Below are precautions for using different types of spare tires: 1. Full-size spare tires have identical specifications and size to the other four tires on the vehicle. They can replace any temporarily or permanently unusable tire. 2. Non-full-size spare tires have slightly smaller diameter and width compared to the original tires. They can only be used as a temporary replacement and must be installed on non-driving wheels. The maximum speed should not exceed 80 km/h. Below is extended information on storing car spare tires: 1. Regularly inspect the spare tire: Owners should check the spare tire during routine maintenance or before long trips. Key checks include tire pressure, wear, and cracks. If the tread wear reaches the wear indicator line, the spare tire should be replaced immediately. If minor cracks appear on the sidewall, prolonged use should be avoided to prevent blowouts. 2. Keep oil products away from the spare tire: Tires are primarily made of rubber, which can degrade when exposed to oil. If oil contaminates the spare tire, it significantly reduces its lifespan. Any oil stains should be cleaned promptly with detergent. 3. Monitor the spare tire's lifespan: As a rubber product, spare tires age over time. Prolonged storage can lead to severe aging or even failure. Typically, tires have an aging period of about 4 years, after which the spare tire should be replaced.
