Spare tires cannot be used as regular tires. Based on size, spare tires are categorized into non-full-size spare tires and full-size spare tires. The details are as follows: 1. Non-full-size spare tires: The main difference compared to regular tires is that their specifications and size are smaller than those of regular tires. If a non-full-size spare tire is used as a regular tire for an extended period, it can cause uneven pressure on one side of the vehicle, increasing the risk of a tire blowout, which is particularly dangerous during high-speed driving. 2. Full-size spare tires: Although full-size spare tires have the same specifications and size as regular tires, they should not be used as regular tires for long-term use. This is because the four regular tires on a vehicle wear out at a similar rate over time, and using a spare tire in place of a regular one can affect the vehicle's stability during driving.

Hey, as a car enthusiast who often drives long distances, I've personally experienced this. The spare tire is designed for emergencies, like temporarily driving a few kilometers to find a repair shop after a flat tire. Using it as a regular tire? Absolutely not. It's smaller in size, has thinner sidewalls, and is made of inferior materials—driving with it long-term feels extremely unstable. It wobbles badly when taking sharp turns at high speeds, is prone to slipping in the rain, and wears out super fast. Once, I drove 100 kilometers on a mountain road with a spare tire and felt the steering wheel shaking uncontrollably. Upon inspection, the tread was almost worn out, and the rim was deformed—costing me over 800 to fix. Spare tires usually have a speed limit of 50 to 80 km/h; exceeding that is dangerous and also consumes more fuel. My advice: use the spare tire for no more than a few dozen kilometers, fix the original tire issue immediately, and don’t neglect regular maintenance like checking the spare tire’s air pressure. Safety first—don’t cut corners and risk big trouble.

Buddy, I've been driving for over a decade, and let me tell you - spare tires are strictly for emergencies, never use them as regular tires. That thin little spare is designed to save space in your trunk for emergencies, but it's full of problems on long drives - thin tread wears fast, excessive vibration damages suspension systems, and with its low speed limit, it starts squeaking if you barely exceed 80 km/h. When I used my SUV's spare once on the highway, the balance was terrible and fuel consumption skyrocketed. From a safety perspective, spares have weaker pressure resistance and traction - if you crash, the damage is worse and your insurance might spike. I remember a friend who got lazy and used his spare for two months, only to have it blow out and leave him stranded. Rather than facing costly tire replacements later, get regular maintenance - make it a habit to ensure safe and worry-free driving.

From a veteran driver's perspective, a spare tire is not a long-term solution. Its material is inferior to regular tires, with smaller size and weaker load-bearing capacity. Driving on it for extended periods leads to rapid wear and deformation, affecting handling. When I drove a taxi, I once tried using a spare tire on city roads. Within two days, I noticed abnormal tire heat and severe vibrations over bumps. Pulling over to check, I found unstable tire pressure. Spare tires usually have speed limits around 60 km/h, posing significant safety risks over time. It's advisable to replace it with a standard tire immediately after emergency use.
