How fast can a spare tire run on the highway?

Spare tires can run at speeds below 60 mph on the highway. Types of spare tires: Full-size spare tire: Although the tire width is the same, other parameters are different. The material of the full-size spare tire's rim is also different from that of the regular tire. Most original tires have alloy rims, while spare tires have steel rims, which differ in weight, heat dissipation, and other aspects. Therefore, a full-size spare tire cannot be used as a new tire. Non-full-size spare tire: Non-full-size spare tires are narrower than the original tires and cannot be used as regular tires. Otherwise, it will lead to a decrease in braking and driving force, and due to the different treads on both sides, the vehicle may pull to one side. This will have a noticeable impact on the car's braking performance and handling, compromising safety. Purpose of spare tires: To provide a backup tire for the 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.
As someone who drives frequently, let me tell you about the speed at which a spare tire can be used on the highway. Most spare tires are not full-size and are only designed for temporary emergency use. They are typically rated for about 80 kilometers in distance and should not exceed a speed of 80 kilometers per hour. This is because spare tires are not as durable as regular tires and can overheat or deform at high speeds, increasing the risk of a blowout. The last time I used a spare tire on the highway, I noticed the car felt unstable at just 70 km/h, and there was a lot of noise. My advice is to visit a repair shop immediately after installing the spare tire for a proper check-up—don't delay. Also, make sure the spare tire is properly inflated; being too soft or too hard can compromise safety. In summary, spare tires are meant for short-distance, low-speed transitions only. Never attempt to speed or drive long distances with one—safety comes first.
Don't drive too fast on the highway with a spare tire. Based on my personal experience, keep it under 80 km/h. There are two types of spare tires: full-size ones are somewhat better, while non-full-size ones are just temporary helpers. Speeds above 70 km/h can easily cause problems. A friend of mine drove at 90 km/h on the highway with a spare tire, resulting in a deformed wheel rim and repair costs over a thousand yuan. From a safety perspective, high-speed driving poses significant risks. Spare tires are made of thinner material, and the high friction-generated heat may lead to a blowout. It's also advised not to exceed 80 km in distance—head straight to a repair shop after changing it. Additionally, remember to stop in a safe place before changing the spare tire and check if the tire pressure is appropriate. It's okay for temporary emergencies, but don't push your luck if it's unsafe.
How fast can a spare tire run on the highway? I've been driving for many years, and spare tires are generally for temporary use. It's best not to exceed 80 kilometers per hour. Non-full-size spare tires are narrower and unstable at high speeds, which may cause shaking or loss of control. I recommend keeping the speed between 60 and 70 km/h and not driving too far—within 80 kilometers is safer. The key reason is that once the speed is too high, the temperature rises quickly, accelerating tire wear. Remember to check the tire pressure before use to avoid additional issues.
