How Far Can You Drive With A Spare Tire?

When you get a flat, having a spare tire could be the difference between maintaining your daily schedule and spending hours at a repair shop. Here are answers to common questions on spare tire usage, including how far you can drive before a replacement is needed.

Does Your Vehicle Contain a Spare?

Assuming a vehicle contains a spare is dangerous for motorists who set out on long journeys with aging tires. According to a 2014 Consumer Reports test, many manufacturers are replacing heavy spares and jacks with smaller, lighter inflator kits in an effort to increase marketable gas mileage. If the car you drive does not have a backup, learn how to use the tire inflator kit before a blowout.

What Type of Spare Tire is Included?

While the most common spare is a thinner, compact version of the original tire, called a “donut,” older vehicle models may have a full-sized tire included as the fifth-wheel backup. If your car does have a full-sized spare, read the owner’s manual to find out the exact specifications. In many cases, the full-sized wheel can be used temporarily, but is made of lesser-quality materials and shouldn’t be depended on as a long-term replacement after a blowout.

Is the Spare Inflated?

After transportation authorities observed an increase in vehicle accidents as a result of low tire pressure, the Transportation Recall Enhancement, Accountability and Documentation Act was passed into law in 2007. Since then, all vehicles must include a pressure monitoring system. By measuring tire revolutions through the braking system, the engine’s computer will alert drivers of low pressure through an indicator dashboard light.

While this measure helps motorists track the condition of their current set of wheels, the spare tire pressure must be manually monitored. It is also useful to fill up the spare tire with air every time the regular wheels require a firming up. Unused, unattended spares in the trunk are exposed to extreme temperatures in the changing seasons and require a tire pressure check so they will be ready when needed. Also, if you own a car over 10 years old, the spare tire may need replacement. Reference the owner’s manual for individual guidance.

What Are the Mileage Limits for a Spare?

Spares are commonly only useful for 50 miles. Since each manufacturer may differ, read the owner’s manual to verify the mileage limits. In addition, when using a compact spare, motorists should always drive under 50 mph and avoid highways.
