Is the Spare Tire the Same as the Original Tire?

[Phoebe]

Spare tires are not the same as original tires. There are two types of spare tires for cars: full-size spare tires and non-full-size spare tires. Generally, vehicles come with non-full-size spare tires. When purchasing a car, it is recommended that owners inquire in detail about the spare tire. The following are precautions for using a spare tire: 1. Regularly inspect the spare tire: Owners should check the spare tire during routine maintenance or before long trips, focusing on tire pressure, wear, and cracks. If the tread wear reaches the wear indicator line during inspection, the spare tire should be replaced promptly. If there are fine cracks on the sidewall of the spare tire, prolonged driving should be avoided as it may lead to a blowout. 2. Keep oil products away from the spare tire: Tires are primarily made of rubber, which can be eroded when mixed with oil products. Many owners often store lubricants and other oil products in the trunk. If these come into contact with the spare tire, the lifespan of the spare tire can be significantly reduced. If oil stains accidentally get on the tire, they should be washed off immediately with detergent. 3. Pay attention to the lifespan of the spare tire: As a rubber product, spare tires age over time. Prolonged storage can lead to severe aging or even failure. Typically, the aging period for tires is about 4 years, after which the spare tire should be replaced.
