Temporary spare tires will not cause pulling. The term 'temporary spare' refers to a tire with a different tread width, typically narrower than the four main tires. For example, while a standard tire might be 205 in width, a temporary spare is usually around 100 to 120 in width. However, the overall diameter (or height) of the temporary spare matches that of a full-size tire. Temporary spares are designed for emergency use only, not for long-term driving. Regardless of width, manufacturers impose specific production and usage requirements on spare tires. Since they are not used continuously on the vehicle and thus experience no wear, a new spare tire behaves differently from a worn-out regular tire. Using a spare tire on the vehicle inherently carries certain safety risks.

Non-full-size spare tires do sometimes pull to one side. After decades of driving, I've seen this happen a lot. These spares are usually smaller in diameter and width than regular tires, creating differences in rolling radius that make the vehicle drift sideways. The effect is more pronounced when mounted on the front wheels - you'll feel the steering go loose. I remember once changing a tire on a provincial highway, and the car just wouldn't track straight - scared me good. For safety, I always recommend mounting spares on the rear axle first; it reduces the pulling. Tire pressure matters too - spares often require higher PSI, so check your manual. Remember, these temporary spares have an 80 km/h speed limit. Driving slower means less risk. They're fine for short distances, but get your regular tire fixed ASAP. Regular tire inspections help prevent issues too.

In daily car repairs, I often hear car owners complain about non-full-size spare tires causing the vehicle to pull to one side. The imbalance caused by wheel differences is usually the main reason, especially when the size mismatch interferes with the vehicle's trajectory control. During installation, it's crucial to place the spare tire on the rear axle first to avoid uneven force distribution on the front wheels, which can exacerbate the issue. Checking tire pressure is essential, as spare tires with different specifications may need to be adjusted to standard values. While the risk of pulling isn't 100%, it's relatively high, especially when handling becomes unstable during turns. Based on experience, it's recommended to keep driving speeds between 60-70 km/h and avoid long-distance travel. Additionally, promptly inspect rim wear, as spare tires have a short lifespan and are only for emergencies. Maintaining low speeds and a stable position are key points.

As a driver, my car comes with a compact spare tire. I've used it twice without encountering severe pulling issues. As long as it's mounted on the rear wheels, the ride remains fairly stable with no major handling problems. Just adjust the tire pressure according to instructions and don't exceed the speed limit – it's generally sufficient for city driving. It's safe for short-term use, but don't rely on it long-term; replace it at the first opportunity. The spare tire is designed as a temporary solution, so there's no need to worry too much about it.

From a safety perspective, non-full-size spare tires pose a significant risk of veering. The size difference may disrupt wheel balance, causing yaw or vibration during driving, especially at high speeds or on curves. I always strictly install them on the rear wheels and ensure correct tire pressure to avoid exacerbating imbalance. During driving, avoid sudden acceleration and sharp turns, maintaining moderate to low speeds for greater stability. Spare tires are for emergency use only; replace them at a repair shop immediately after use to minimize accidents. Personal experience shows that cautious operation can maximize risk control, making journeys more reassuring.
