Spare Tire Buyer’s Guide: How To Choose The Right Backup Tire

An image of a man installing a spare tire on his vehicle on the side of the road.

Most modern vehicles do not include a spare tire anymore but that doesn’t mean you shouldn’t consider one.

The right spare tire depends on your vehicle, driving habits, and what degree of risk you’re willing to take in an emergency. Our guide breaks down how to choose the right spare tire and enjoy peace of mind.

DO YOU NEED TO BUY A SPARE TIRE?

That depends on how you feel about dealing with a potential emergency situation.

Most newer vehicles, which are designed to be as efficient as possible, do not include a spare tire because they take up space and add weight.

Instead, many new vehicles come with inflator kits or run-flat tires. These options save space but they don’t always work in real-world situations, especially with larger punctures or sidewall damage.

Consider buying a spare tire if you:

  • Regularly drive long distances or take road trips
  • Commute in rural or low-service areas
  • Own a truck, SUV, or older vehicle without run-flat tires
  • Want a reliable backup for emergencies

If your vehicle does include a spare tire, regularly check its tire pressure and tread health. Many spare tires go unused for years and may no longer be safe when you eventually need them.

SPARE TIRE TYPES: WHAT ARE YOUR OPTIONS?

There are two main types of spare tires. The best one depends on how you intend to use it.

  1. Full-size spare tire
    A full-size spare matches your regular tires in size and performance.

  2. Best for:
    -Daily drivers
    -Long-distance travel
    -Trucks and SUVs

    Tradeoffs:
    -Takes up more space (some vehicles won’t have room)
    - Heavier than compact spares

  3. Compact temporary spare (donut)
    A compact spare (called a “donut”) is smaller, lighter, and designed for temporary use only.

  4. Best for:
    -Emergency situations
    -Drivers with limited storage space
    -Budget buyers

    Tradeoffs:
    -Lower speed and distance limits
    -Reduced traction and handling

Below is a quick reference guide to the differences between compact spares versus full-size spares.

Comparing Compact Spare vs Full-Size Spare Tires
Type Size Storage Cost Performance
Compact “donut” spare Smaller than typical tire Usually fits under vehicle or in specially designated trunk compartment Can be less expensive
  • Reduced braking and traction
  • Can only go up to 50 miles at 50 mph
  • Only a temporary fix
Full-size spare Same size as regular tire Must be stored on rack or in trunk Can cost as much as regular tire
  • Same performance as a regular tire
  • Can be used as a regular tire; more permanent solution

HOW TO CHOOSE THE RIGHT SPARE TIRE

Keep in mind that many aftermarket spare tires do not come with a wheel. You must purchase the wheel separately and have it mounted at a tire repair shop. Some aftermarket spare tires do come with wheels already mounted.

Not all spare tires fit every vehicle. Just like regular tires, it comes down to tire size and fitment, driving conditions, available storage, and vehicle type.

  1. Match your tire size and fitment
  2. Your spare tire must match your vehicle’s:
  3. Consider your driving conditions
    How and where you drive will have an impact on what type of spare you choose:
    • Highway: Compact or spare, depending on your risk comfort level
    • City: Compact spare may be adequate
    • Off-road or towing: Full-size is recommended
  4. Know your vehicle type
    Your vehicle’s drivetrain type (ex: FWD, AWD) should determine your choice of spare. Mismatched tire sizes in AWD and 4WD vehicles can cause drivetrain damage. In many cases, a full-size spare is the safest option.

  5. Check your storage space
    Before buying, confirm where the spare will go and how much space you have available:
    • Under trunk cargo floor (typical in cars and crossovers)
    • Under passenger area floor (typical in minivans)
    • Mounted under vehicle (typical in pickup trucks, usually full-size)
    • Rear-mounted (SUVs/Jeep style vehicles; typically full-size)

If you want a full-size spare in a car, crossover, or minivan, you may have to give up some valuable trunk storage space.

How Much Is A Spare Tire?

Spare tires can range in price from about $80 and up, depending on the size and brand tire. Full-size spare tires will cost as much as your regular tires. You can also purchase an entry cost tire, such as the Mohave CUV (crossovers), Sentury Touring (passenger vehicle), or Sentury UHP (high performance vehicles) as a full-size spare that will do the job until you can purchase an identical fourth tire.

Do Spare Tires Come With Wheels?

Many aftermarket spare tires do not include a wheel, so you’ll typically need to purchase a compatible wheel separately. A low cost but durable steel wheel is often the preferred choice. We like the Unique 83 or the Liquid Metal Atom.

WHEN A FULL-SIZE SPARE TIRE IS WORTH IT

A full-size spare isn’t necessary (or even practical) for every driver, but in some situations it is the better investment.

Consider upgrading to a full-size spare if you:

  • Take frequent road trips
  • Have adequate storage space
  • Drive in remote areas
  • Tow heavy loads
  • Drive rough roads or off-road trails
  • Want consistent handling after a flat

Unlike compact “donut” spares, full-size tires can be driven long-term and rotated into your tire set.

SPARE TIRE MAINTENANCE

Remember: your spare tire is no help if it’s not ready to use.

Make sure to:

  1. Check the air pressure at least once a month
  2. Regularly inspect for cracks or dry rot
  3. Replace the tire every 6-10 years, even if unused

Keeping your spare tire in good condition ensures it’s ready when you need it most.
