Can I drive 200 miles on a full-size spare tire?
Yes, you can typically drive about 200 miles on a true full-size spare, provided it matches your regular tires in size and load rating. If your spare is not a true full-size tire—such as a donut or one that doesn’t match the other tires—the safe distance is usually much shorter, and you should consult your manual and replace the tire promptly.
What counts as a full-size spare?
To determine whether your spare qualifies as a true full-size tire, verify these factors:
- Size and diameter match your other tires (same overall circumference or very close).
- Load index and speed rating align with your vehicle’s requirements.
- Wheel type and mounting compatibility (same bolt pattern and center bore).
- Condition, tread depth, and absence of damage or bulges.
- Manufacturer guidance in your owner's manual regarding spare use and replacement timelines.
Bottom line: A spare that is truly the same size and capability as your other tires supports normal driving, including longer trips, whereas a mismatched or damaged spare warrants caution.
Distance and safety: driving 200 miles on a spare
When the spare is a genuine full-size tire that matches the other tires, driving 200 miles is generally acceptable, assuming you drive normally and avoid aggressive handling, heavy loads, or extreme weather. If the spare is older, has worn tread, or is different in size or construction, you should reduce distance and seek a proper replacement as soon as possible. Always follow your vehicle’s manual for any quoted limits or recommendations, especially if your car is equipped with advanced systems that rely on uniform tire sizing.
Special considerations for AWD/4WD vehicles
All-wheel-drive and four-wheel-drive vehicles are more sensitive to tire size differences. Using a spare that differs in diameter from the other tires can stress the drivetrain, transfer case, or differentials, potentially causing damage. If your vehicle requires a spare that matches the others exactly, use a true full-size spare that mirrors the regular tires. If you must use a non-matching spare, minimize driving distance and replace with matching tires as soon as feasible; consult the owner’s manual for explicit guidance related to your drivetrain.
Practical steps before you depart with a spare
Before driving with a spare, perform these checks to reduce risk and ensure safety:
- Check that the spare’s tire size matches the other tires and that the wheel is compatible with your vehicle.
- Inspect tread depth and look for cracks, bulges, or signs of age; a spare with poor tread or aging rubber should be replaced.
- Verify proper inflation to the recommended pressure for the spare and ensure the other tires are within their required pressures.
- Ensure lug nuts, lug wrench, and wheel bolts are in good condition and that you know the correct torque specification for your vehicle.
- If you have an AWD/4WD system, review the manual for any special instructions about tire replacement or rotation while using a spare.
Bottom line: Preparing and inspecting the spare before a trip helps ensure that a 200-mile drive remains safe and manageable while you arrange a proper tire replacement.
Summary
A true full-size spare that matches your regular tires allows normal driving, including a 200-mile trip, as long as it is in good condition and properly inflated, and your vehicle’s guidelines are followed. If the spare is a donut or otherwise mismatched in size or rating, limit distances and seek replacement promptly. For AWD/4WD vehicles, matching tire size is especially important to avoid drivetrain damage. Always consult your owner’s manual for model-specific guidance and prioritize replacing tires to restore uniform performance.
How fast can I drive with a full-size spare tire?
You can typically drive at normal speeds, up to 70 mph, on a full-size spare tire because it is the same size as your regular tires. However, always check your vehicle's owner's manual for the specific recommended speed limit and distance, as they can vary by car. Drive cautiously and get a full-size spare replaced or a regular tire repaired as soon as possible.
Full-size spare
- Speed: You can usually drive at normal road speeds, up to 70 mph.
- Distance: There is no distance limitation, as it is designed for long-term use.
- Caution: Even though it's a full-size spare, it's still best to drive cautiously and have your regular tire fixed or replaced as soon as you can.
Temporary spare ("donut")
- Speed: Do not exceed 50 mph.
- Distance: Do not drive more than 50 miles.
- Caution: Temporary spares are not meant to be a permanent replacement and are designed for emergencies only. Driving faster than recommended can cause the tire to overheat and potentially blow out.
How many miles can a full-size spare tire last?
You can drive on a full-size spare tire as long as you need, but you should treat it like a regular tire and replace it as soon as possible. Unlike a "donut" spare, a full-size spare does not have the same distance or speed limitations, but it's crucial to check that it's properly inflated and in good condition. Always prioritize getting your regular tire repaired or replaced, and have your lug nuts checked for proper tightness at the shop.
Driving guidelines for a full-size spare
- Speed and distance: You can drive at normal speeds, but it's still best to drive cautiously. There is no strict mileage limit, but it's not meant to be a permanent replacement for a regular tire.
- Check pressure and condition: Before driving, ensure the tire is fully inflated and free from any damage, such as cracks or bulges.
- Replace promptly: Get your flat tire repaired or replaced as soon as you can, and don't delay in replacing the spare if it's old or damaged.
- Avoid rough roads: Drive cautiously and avoid rough roads to minimize wear and tear.
- Have lug nuts checked: After installing the spare, have the lug nuts tightened to the manufacturer's specifications to ensure they are secure.
Is it okay to drive on a full-size spare tire?
Yes, you can drive on a full-size spare tire, and it is designed to be used like a regular tire, but you should still replace the flat as soon as possible. Full-size spares can be driven for longer distances and at normal speeds because they match the size of your other tires. However, it is recommended to get your regular tire repaired or replaced promptly to maintain the best handling and traction, especially if the spare has been stored for a while.

Driving with a full-size spare
- Driving duration and speed: You can drive on a full-size spare like a regular tire, but it's still best to replace it with a permanent fix as soon as possible.
- Handling and traction: While a full-size spare is a better option than a temporary "donut" spare, it may still affect your car's handling and traction, especially if it's been stored for a long time.
- Tread and condition: A full-size spare should be in good condition. If it has been stored for a long time, it may be degraded, so it is still best to drive cautiously.
- Maintenance: You should get the original tire repaired or replaced as soon as you can.
- Consult your manual: Always check your owner's manual for specific recommendations for your vehicle.
Full-size vs. temporary spare
- Full-size spare: The same size as your other tires, providing a more seamless and safer experience. It can be driven for longer distances and at normal speeds.
- Temporary (donut) spare: Smaller than your other tires and has speed and distance limitations, typically a maximum of 50 miles and 50 mph. It is designed only for a short-term fix to get you to a service center.
How long can I drive 200 miles on a donut?
You should drive no more than 50 miles on a temporary or donut spare tire if possible. If you absolutely must go longer than 50 miles, avoid driving on it longer than 70 miles. A spare tire isn't meant to completely replace a tire, rather, its purpose is to tide you over until you can properly replace it.
