How Many Kilometers Can a Spare Tire Be Driven?

[LeAlan]

Spare tires can be driven for a certain number of kilometers depending on their type: 1. A full-size spare tire can be driven for over 100 kilometers; 2. A compact spare tire can be driven for no more than around 60 kilometers. A spare tire refers to an extra tire for a car, which has the same specifications as the original car tires. Precautions for using a spare tire include: 1. Regularly inspecting the spare tire; 2. Not using it for an extended period; 3. Avoiding rotating the spare tire with other tires; 4. Keeping it away from oil products. Spare tires are categorized into full-size spare tires, compact spare tires, and run-flat tires. Depending on the vehicle model, they are usually placed: under the trunk floor, hanging below the rear of the car, or fixed outside the trunk door.

Last time I changed the spare tire, I asked the repair shop mechanic. The non-full-size spare tire - that small, narrow one - shouldn't exceed 80 kilometers in total distance, and speed must be kept under 80 km/h. For full-size spares that match the original tires, you can go a bit farther but don't exceed 200 kilometers. This is mainly because spare tires have thinner rubber and shallower tread patterns, resulting in poor grip. Prolonged use can cause deformation or even blowouts. Last week my neighbor drove over 100 kilometers on a spare and ended up with scratched wheel rims. My advice is to visit a repair shop immediately when you see one - never treat a spare tire as a regular tire.

As someone who frequently drives long distances, I'd like to remind everyone to pay special attention to the yellow speed limit sticker on the spare tire - the number indicates the maximum speed limit. The spare tire on my SUV is marked 80km/h, but in practice even 80 feels too fast. Spare tires usually have higher tire pressure, making the steering noticeably floaty, especially on highways during rain when you dare not step on the accelerator. I recommend keeping both hands firmly on the wheel when driving with a spare and slowing down well before curves. The longest I've driven on a spare is 50km before rushing to a repair shop - after all, the cost of a tire blowout far exceeds towing fees.

Lessons from changing three spare tires: A non-full-size spare is essentially an emergency tool. Its rubber compound and sidewall strength differ from regular tires, with the maximum safe distance being the trip to a repair shop. In urban areas, it's advised not to exceed 30 kilometers, and in suburbs, no more than 80 kilometers. Last autumn, I deliberately tested it while driving on a spare—beyond 60 kilometers, a burnt rubber smell became noticeable, and the wheel hub was scalding to the touch. Don't hesitate over towing fees; it's best to include roadside assistance when purchasing insurance.

Automotive engineers warn: Most car spare tire wells are only deep enough to accommodate temporary tires. Non-full-size spare tires have 30% less contact area than regular tires, increasing braking distance by 40% during continuous driving. We've seen customers using spare tires for two months, resulting in cracked treads. It's recommended to reset the tire pressure monitoring system immediately after installing the spare tire and prioritize driving to an auto repair shop rather than the destination. If a flat tire occurs in remote areas, drive slowly on the spare tire to a location with mobile signal to call for assistance, and never risk long-distance travel.

Auto repair shop owners often say they dread encountering drivers who drive their spare tires to destruction. In fact, spare tire rims are made of thinner materials and are prone to becoming out-of-round with prolonged use. The most extreme case we've seen in our shop was a customer who drove their spare tire from Lhasa to Chengdu—after 1,600 kilometers, the tire was completely worn through. We recommend checking the condition of your spare tire before setting off; many vehicles have spare tires that haven't been touched in five years and have already aged. After changing to a spare tire due to a flat, you should find a professional shop nearby for inspection. Mixing old and new tires can lead to abnormal wear on the suspension system.
