Yes, but only as a temporary fix to get to a tire shop

You can drive on a spare tire, but it is not a permanent solution and comes with real limits on speed and distance. A spare tire is designed to get you to a repair shop safely — not to replace a full tire for the long term. How far you can go and how fast you can drive depend on which type of spare you have, what your vehicle manual says, and the road conditions you're facing.

Most drivers do not know their spare's limits until they need it. Driving beyond those limits risks blowouts, loss of traction, and damage to your transmission or differential. Understanding what your spare can handle before you have a flat is the difference between a minor inconvenience and a roadside breakdown that costs hundreds of dollars to fix.

Key Takeaways

  • Temporary spares (the small donut-shaped tires on most cars) are rated for 50 to 70 miles at speeds under 50 mph, though your owner's manual has the exact limits for your vehicle.
  • Full-size spares (matching your other tires) can handle longer distances and higher speeds, but are still meant as temporary solutions unless your manual says otherwise.
  • Driving faster than recommended or farther than rated can damage your transmission, differential, and brakes, especially on all-wheel-drive vehicles.
  • Your spare tire pressure and tread depth matter just as much as the tire itself — check both before you drive, and have your flat repaired or replaced within a day or two.

Temporary spares have strict distance and speed limits

A temporary spare — the small, skinny tire that comes on most modern cars — is rated for 50 to 70 miles of driving at speeds under 50 mph. Some vehicles allow up to 50 mph; others cap it at 45 mph. Your owner's manual or the sidewall of the spare itself will state the exact limit for your car. Driving faster or farther than these limits puts stress on parts designed for normal tire size and weight distribution.

The reason for these limits is straightforward: a temporary spare is thinner and smaller than your regular tires, which means it rotates faster to cover the same distance. That faster rotation puts extra strain on your transmission, differential, and brakes. On all-wheel-drive vehicles, the mismatch between the spare and your other three tires is especially hard on the drivetrain because all four wheels are trying to turn at different speeds. Ignoring these limits can cost you $1,000 to $3,000 in transmission or differential repairs.

If you are more than 70 miles from a tire shop, or if you cannot stay under the speed limit, call a tow truck. It will cost $100 to $300, but it is cheaper than the alternative.

Full-size spares give you more flexibility but are still temporary

Some vehicles come with a full-size spare that matches your other tires in diameter and width. These spares can handle longer distances and higher speeds than temporary spares — often 500 miles or more at normal highway speeds, depending on your manual. A few vehicles are designed so that a full-size spare can be used permanently as a replacement tire, but this is rare and your manual will explicitly say so.

Even with a full-size spare, you should treat it as a temporary solution. A spare tire is often stored under the trunk floor or on the back of the vehicle, exposed to weather and temperature swings. It may have been sitting for years and could have lost air pressure or developed dry rot. Before you drive on it, check the tire pressure with a gauge and look for cracks or bulges in the sidewall. If the spare looks damaged, do not drive on it — call a tow truck instead.

Once you are on the road with a full-size spare, get your flat tire repaired or replaced within a day or two. Driving on a spare for weeks or months puts wear on it that a spare is not designed to handle, and you lose the backup if you get another flat.

Check your spare's pressure and condition before you drive

A spare tire sitting unused for months or years will lose air pressure. A tire that is underinflated by even 10 psi will overheat faster, wear unevenly, and give you less traction. Before you drive on your spare, use a tire pressure gauge to check the psi and compare it to the pressure listed on your driver's door jamb or in your manual. If the spare is low, use an air pump to bring it to the correct pressure.

While you have the spare out, inspect it for visible damage: cracks in the sidewall, bulges, punctures, or areas where the rubber looks dried out or cracked. If you see any of these, the spare is not safe to drive on. Call a tow truck or a mobile tire service to come to you. Do not risk a blowout at highway speed.

Check the tread depth too. A spare with less than 2/32 of an inch of tread is at the legal minimum and may not give you enough grip in wet conditions. If the tread is that low, treat the spare as a last resort and keep your speed and distance to the absolute minimum.

All-wheel-drive vehicles have stricter spare tire rules

If you drive an all-wheel-drive (AWD) vehicle, using a spare tire — especially a temporary one — is harder on your drivetrain than on a two-wheel-drive or front-wheel-drive car. An AWD system sends power to all four wheels and expects them to turn at nearly the same speed. When one tire is smaller or has different tread than the others, the system detects the mismatch and can engage the center differential or transfer case to compensate. This puts extra load on parts not designed for sustained use under those conditions.

Some AWD vehicles have a rule: do not drive on a spare at all, or only for very short distances (under 10 miles) at low speeds. Check your owner's manual for your vehicle's specific rule. If your manual says not to use a spare, or if it limits you to under 10 miles, call a tow truck. The cost of towing is far less than the cost of repairing an AWD transmission or differential.

If your manual allows spare tire use on your AWD vehicle, follow the distance and speed limits exactly. Do not assume that because you drove on a spare before without problems, you can do it again — each vehicle is different, and each spare has limits.

What to do if you cannot reach a tire shop

If you have a flat and the nearest tire shop is more than 70 miles away, or if your spare is damaged or missing, you have a few options. A mobile tire repair service can come to you and patch or replace the tire on the roadside — search "mobile tire repair near me" or call roadside information if you have it through your insurance or an auto club. This usually costs $75 to $150 and takes 30 to 45 minutes.

If the tire cannot be repaired (the puncture is too large, or the damage is in the sidewall), you will need a replacement. A tow truck will take you and your car to a shop, which costs $100 to $300 depending on distance. Once at the shop, a new tire will cost $100 to $300 depending on the brand and size.

If you do not have roadside information and cannot afford a tow, some tire shops offer free towing if you buy a tire from them. Call ahead and ask. You can also check whether your auto insurance includes roadside information — many policies do, and you may not know it.

How to avoid needing a spare in the first place

The best way to handle a spare tire is to not need one. Check your tire pressure once a month using a gauge (not the tire pressure monitoring system light, which comes on only when pressure is very low). Underinflated tires wear faster and are more prone to punctures. Keep your tires inflated to the psi listed on your driver's door jamb, not the number on the tire sidewall.

Inspect your tires visually every few months for uneven wear, cracks, or objects embedded in the tread. Rotate your tires every 5,000 to 7,000 miles to spread wear evenly. Replace tires when tread depth reaches 4/32 of an inch — do not wait until the legal minimum of 2/32. Tires with more tread give you better grip in wet conditions and are less likely to puncture.

Avoid potholes, debris, and rough roads when you can. If you hit a pothole or curb, pull over safely and check your tires for damage before driving on. A small bulge or crack can turn into a blowout within miles.

Frequently Asked Questions

Can I drive on a spare tire for a week or two?

Not safely. A temporary spare is rated for 50 to 70 miles; a full-size spare for longer, but still as a temporary fix. Driving on a spare for a week puts stress on your transmission and differential that can cause expensive damage. Get your flat repaired or replaced within a day or two, or rent a car for longer trips.

What if my spare tire is flat?

A flat spare is useless. Call a tow truck or mobile tire service. Do not try to drive on a flat tire — you will damage the rim and the tire beyond repair. If you discover your spare is flat after a breakdown, you have no choice but to call for help.

Is it okay to drive on a spare tire in the rain or snow?

Temporary spares have less tread and grip than regular tires, so rain and snow make them riskier. Slow down, increase your following distance, and avoid sudden braking. If conditions are severe, do not drive — wait for better weather or call a tow truck.

Do I need to replace my spare tire if it is old?

Yes, if it shows cracks, dry rot, or has been sitting unused for more than six years. Rubber degrades over time even if the tire is not driven on. Before a long road trip, have your spare inspected by a tire shop to make sure it is safe to use.

Can I use a spare tire from a different car?

Only if it is the same size and load rating as your vehicle's spare. Using a mismatched spare can cause the same transmission and differential damage as driving too far on your own spare. Check your owner's manual for the correct tire size and load rating before using any spare.
