How far can you realistically drive on a spare tire?

In most cars, a spare tire is a temporary fix designed to get you to a repair shop. Compact “donut” spares are typically good for about 25–50 miles at a maximum of 50 mph, while a full‑size spare can be driven like a regular tire but should be replaced promptly. Always check your owner’s manual for the exact limits on your model.

The question of distance depends on the spare type you have and the vehicle you drive. This article explains the different spare configurations, their practical driving limits, and best practices so you can plan a safe route to service after a puncture.

Spare tire types and their limits

Spare tires come in several configurations, each with different limits on distance and speed. Here’s a quick guide to what to expect on the road.

Types at a glance

Compact donuts, full-size spares, and kit-based temporary solutions each demand different behavior.

• Compact spare (donut): Typically rated for about 25–50 miles (40–80 km) and a maximum speed of around 50 mph (80 km/h). Exact numbers vary by model; always check the vehicle’s manual or the sidewall for specifics.


• Full-size spare: A genuine full-size spare is usually the same size and tread as your regular tire and has no official mileage limit. Drive normally, but replace it soon and be mindful of any mismatches that could affect handling, especially on AWD/4WD systems.


• Vehicles without a spare (sealant kit or run-flat emphasis): Some newer cars ship without a traditional spare and rely on a tire-sealing kit or run-flat tires. In these cases, distance and speed guidance come from the kit’s instructions and the manual, not from a standard spare tire chart.

Understanding these limits helps you plan your route and approach to service without taking unnecessary risks.

Safety and best practices when using a spare

To stay safe while driving on a spare, follow these guidelines.

• Check spare tire pressure and ensure it is inflated to the recommended level before you drive away.


• Adhere to the speed and distance limits specified for your spare or in your owner’s manual. Spare tires are temporary and not designed for long trips or high-speed driving.


• Avoid highway driving over long distances on a spare; plan to reach a repair facility as soon as possible.


• Once you reach a shop, have the damaged tire repaired or replaced and restore your vehicle’s normal tire configuration if required.


• Do not mix tires of different types or wear on AWD/4WD vehicles unless the manual specifically allows it; mismatches can affect traction and safety.

Following these steps reduces risk and helps you get back to normal driving quickly and safely.

Practical planning for punctures

When you have a puncture, a calm, planned approach matters. The following checklist helps you stay safe and efficient on the way to service.

1. Pull over to a safe location and turn on hazard lights.


2. Inspect the spare, the wheel hardware, and the jack to ensure you can install it correctly.


3. Check and, if needed, adjust the spare’s tire pressure to the recommended level.


4. Install the spare following the vehicle’s manual steps, taking care not to overtighten lug nuts.


5. Drive conservatively to the nearest repair facility and avoid exceeding the spare’s speed limit.

After you reach a shop, have the original tire repaired or replaced and return your vehicle to its standard tire setup as soon as feasible.

Summary

Spare tires are intentionally temporary solutions. Compact donuts are typically limited to about 25–50 miles at up to 50 mph, while full-size spares can be used longer but should be replaced promptly. Some modern vehicles rely on tire-sealant kits or run-flat systems, which come with their own distance rules. Always consult your owner’s manual and the spare’s sidewall for model-specific guidance, and prioritize a quick, safe trip to a repair facility to restore full driving capability.

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. 

Can you go 70 mph on a spare tire?

No, you cannot safely go 70 mph on a spare tire, as most temporary spares have a maximum speed limit of 50 mph. Driving at high speeds on a spare can damage the tire and your vehicle, and it reduces your car's stability and braking performance. Always check the side of the tire for the manufacturer's speed rating, or refer to your owner's manual for specific recommendations. 
Key points for driving on a spare tire

• Speed limit: Do not exceed 50 mph, regardless of the type of spare (compact or full-size). The speed rating on a full-size spare may be higher, but a temporary spare is a "no-go" above 50 mph. 
• Limited use: Spare tires are for emergency, temporary use only and are not a substitute for a normal tire. 
• Replace as soon as possible: Take your car to a mechanic or tire shop to have your regular tire repaired or replaced as soon as possible. 
• Driving behavior: Drive cautiously, avoid sudden stops and sharp turns, and be mindful of the reduced grip and braking performance. 
• Check pressure: Keep the spare tire properly inflated, as it can lose air faster than a regular tire. 

What happens if I drive more than 50 miles on a spare?

Going over 50 mph on a temporary spare tire can lead to a blowout due to excess heat and stress, a loss of vehicle control, or damage to your car's drivetrain. Temporary spares are not designed for high speeds or long distances and have limitations in load capacity and handling compared to standard tires.
 
What can happen

• Tire failure: Excessive speed, especially combined with long distances, can generate heat and stress on the tire, potentially causing it to fail or blow out. 
• Loss of control: Spare tires, particularly "donut" spares, offer less grip and stability. Driving at high speeds significantly increases the risk of losing control of the vehicle, especially during braking or cornering. 
• Vehicle damage: Driving faster or for too long on a spare can cause damage to other components of your car, including the transmission, differential, or stability systems. 
• Safety risks: In addition to tire and vehicle damage, driving a spare beyond its limits can lead to a serious accident, causing injury to yourself and others. 

What to do instead

• Drive cautiously: Drive slowly and carefully, avoiding sudden maneuvers, hard braking, and sharp turns. 
• Find a repair shop: Get your full-size tire repaired or replaced as soon as possible. A spare is meant for temporary use to get you to a safe place or repair shop. 
• Check the speed and distance limitations: Always adhere to the maximum speed limit printed on the tire (usually 50 mph) and the recommended maximum distance, which is often around 50 miles. 
• Use a full-size spare if you have one: If your spare is the same size as your other tires, it can be driven at normal speeds and for longer distances. 

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.
