How long can you realistically drive on a spare tire?
Spare tires are intended as temporary measures to get you to a repair shop, not as long-term replacements. Most temporary spares are designed for short trips—roughly 50 miles (80 kilometers) at a maximum of about 50 mph (80 km/h). Exact limits vary by vehicle and tire, so always check the owner's manual and the tire sidewall for precise guidance. Pushing a spare beyond those limits increases the risk of a blowout or loss of control.
Types of spare tires and their limits
Spare tires come in several common styles, each with its own mileage and speed restrictions. Here is how the main varieties affect how far you can drive on them.
- Temporary spare (donut): A compact, narrow tire intended to get you to a repair facility. Typically up to about 50 miles (80 kilometers) at speeds no higher than 50 mph (80 km/h).
- Space-saver spare: A slightly larger temporary tire that still functions as a short-term fix. Most guidance limits usage to roughly 50–70 miles (80–112 kilometers) and speeds up to about 50–55 mph (80–90 km/h).
- Full-size spare: A tire the same size as the normal tires. You can drive normally with a full-size spare, but you should replace it as soon as possible if it shows wear or age; there is no built-in mileage limit separate from the tire’s condition.
Because limits vary by model, consult your manual and inspect the spare for sidewall markings indicating the exact mileage and speed ratings.
Practical steps to take when driving on a spare
If you must drive on a spare, take precautions to minimize risk and prevent further tire damage. The following steps help you reach a repair facility safely.
- Check the spare’s pressure and inflate to the vehicle’s recommended level before mounting and driving. A low-spare can fail unexpectedly.
- Drive conservatively: accelerate gradually, avoid hard braking, and keep to moderate speeds. Stay well below the spare’s rated limit.
- Plan the shortest, safest route to a tire shop or service center. Avoid long highway trips if possible and stop to recheck the tire if you notice any handling changes.
- When applicable, consider roadside assistance if you have a long distance to travel or poor road conditions.
Driving on a spare should be considered a temporary measure. The goal is to reach a repair facility quickly and have the damaged tire replaced or repaired as soon as possible.
Safety reminders while using a spare
Spare tires, especially donuts and space-savers, have reduced grip and braking performance. Maintain extra distance, avoid high-speed maneuvers, and be aware of the potential for rapid temperature rise in a compromised tire on hot days or at high speeds.
Special cases: All-wheel drive and electric vehicles
All-wheel-drive, four-wheel-drive, and some electric vehicles have additional considerations when using a spare. Using a spare that isn’t matched to the other tires can upset drivetrain balance, traction, and ABS/traction-control systems. Always follow the vehicle-specific guidance in your manual and, if in doubt, contact roadside assistance.
- For AWD and 4WD systems, install the spare on the axle recommended by the manufacturer and drive within the stated limits. Do not mix new and worn tires across axles.
- Electric vehicles often have limited spare options and may require prompt repair to restore proper range and performance. Follow the vehicle’s guidance and avoid extended use of a spare on EVs.
In all cases, seek professional tire service promptly to restore full traction and handling.
Summary
Spare tires are intended as temporary solutions to reach help. Most donuts and space-savers are rated for roughly 50 miles at up to 50 mph, with some variants allowing up to 70 miles and 55 mph. Always verify the exact limits for your vehicle, drive cautiously, and get the damaged tire repaired or replaced as soon as possible, especially if you drive an all-wheel-drive or electric vehicle.
How far is too far to drive on a spare tire?
You should drive a maximum of 50 miles on a compact or "donut" spare tire, or up to 70 miles in some cases, at speeds no greater than 50 mph. A full-size spare can be driven normally as long as it's in good condition and the same size as the other tires. Spare tires are temporary, so a full-size one should also be replaced with a permanent one as soon as possible.
Compact (donut) spare tires
- Maximum distance: 50 to 70 miles
- Maximum speed: 50 mph
- Purpose: These are designed for emergencies only and are not meant for long-term use.
Full-size spare tires
- Distance: As long as it is in good condition and a matching size to your other tires.
- Purpose: These are a long-term solution, but you should still replace your damaged tire as soon as you can.
Important considerations
- Safety: Driving on any spare tire is less safe than driving on a regular one due to reduced traction and handling.
- Damage: Driving on a spare tire beyond its recommended limits could cause further damage to your vehicle.
- Owner's manual: Always check your owner's manual for the specific mileage and speed limitations for your spare tire.
What happens if you drive 150 miles on a spare tire?
Also, the most you should drive on a temporary tire is around 50 miles or less if you can. If you drive too far on a temporary spare, you can not only end up with another flat but also damage your car.
Can I drive on a spare tire for 2 days?
Yes, you can drive on a spare tire for two days, but only if you keep your speed under 50 mph and limit your driving distance to about 50 miles or less. A spare tire is intended as a temporary solution to get you to a repair shop, and long-term use can compromise safety due to the differences in size, tread, and durability compared to your other tires.
Important considerations for using a spare tire
- Speed limit: Do not exceed 50 mph, as this is the recommended maximum speed for most spare tires.
- Distance limit: Stay within 50 miles. Driving longer distances can lead to more flats or even damage to your vehicle.
- Handle with care: Spare tires have less traction and can affect your vehicle's handling, braking, and steering. Give yourself extra space and time to brake.
- Check tire pressure: Make sure the spare is properly inflated before you drive on it.
- Get it replaced ASAP: Visit a tire shop as soon as possible to have your regular tire repaired or replaced.
What happens if you drive over 50 miles an hour on a spare tire?
Additionally, you shouldn't exceed 50 mph for several reasons. One, the smaller wheel puts added pressure on your steering and suspension. Two, the weaker material won't provide the same protection as a full-size spare tire and rim when encountering debris, potholes, or other imperfections in the road.
