How long can I drive on a spare tire?
You either have a full-size spare tire or a temporary spare tire, much smaller in size and commonly referred to as a donut. If you have a full-size spare, you can drive up to 30,000 miles or more without a problem. However, if you have a donut, most experts recommend driving no more than 70 miles. Most tire shops will carry spare tires. However, an increasing trend is to avoid the traditional temporary “donut” spare tire in favor of a full-sized tire that can be easily switched on your vehicle without any restrictions.Driving Limitations on Spare Tires Compact spare tires, also known as donut spares, are designed for short-term use only. Most manufacturers recommend not exceeding 50 miles and driving no faster than 50 mph due to their reduced traction, which can affect handling and braking.As such, driving on a spare for an extended period of time can increase wear and tear on various components of your vehicle, including the steering, wheel alignment, and more. Drivers should always keep speeds at 50 miles per hour or less while driving on a temporary spare tire.A vehicle with a donut spare does not handle as well as a regular tire. If you are driving in adverse conditions, such as rain, ice, or snow, you will need to be even more cautious as the donut spare tire doesn’t have much tread and will supply little to no traction.Because donuts are so much smaller, they would be mostly ineffective for heavier vehicles but can do the trick for a light sedan. Full-size spare tires are heavier and can create a drag on the back end of smaller vehicles, adversely affecting gas mileage.
Why do cars no longer have spare tires?
To improve fuel efficiency. Removing the spare can reduce a vehicle’s weight by up to 50 pounds, including the jack and lug wrench. It can also improve aerodynamics by reducing air drag from a spare tire that sits below the undercarriage of a vehicle. Given an opportunity to easily shed weight, car manufacturers are going to take it. And because a spare wheel and associated tools can easily add 20kg, ditching it is seen as a ‘quick fix’ by most design engineers.Today, approximately 30 percent of new cars come without a spare (up from just 5 percent in 2006) and it is estimated there are more than 30 million cars on the road that lack a spare tire. The main reason manufacturers are removing spare tires is tough new government fuel economy standards.To Create More Space Removing the spare tire frees up space in the car. This is especially helpful in smaller cars, electric vehicles, or hybrid cars where every inch of space matters. Automakers can use that extra room for larger batteries, extra cargo space, or other features that appeal to buyers.Not only do car manufacturers view full-size spare tires as dead weight, those tires are also more expensive than space-saver spares and their alternatives. A full-size spare’s larger steel wheel or replacement tire mounted on a factory rim can add significantly to a vehicle’s production costs.
Do spare tires fit all cars?
Temporary/Compact Spares The compact temporary spare tire and wheel that comes with a vehicle is designed to fit that vehicle only.

Do not let the tread wear down to the tread wear indicators built into the spare.The compact temporary spare tire and wheel that comes with a vehicle is designed to fit that vehicle only.

Ideally, you should drive a maximum of 50 miles at a maximum speed of 50 mph on a donut. Pushing it further than this can result in damage to the car or, worse, a blowout.And since they’re smaller than your vehicle’s other tires, they have to spin faster to keep up with the moving vehicle. Because of all that, you shouldn’t drive faster than 50 mph on a donut.However, you need to follow safety precautions when using a spare donut tire. Make sure the air pressure is at 60 PSI and keep your speed under 50 MPH.

Check the Pressure: Ensure your spare is inflated to the correct PSI before hitting the road. You can safely drive up to 100 miles with a full-sized spare tire and only 50 miles with a smaller one. A spare tire is an extra tire stored in a vehicle in case of a flat tire. Driving too long on a spare tire causes excessive wear on various parts, plus an increased chance of blowout and tire damage.You either have a full-size spare tire or a temporary spare tire, much smaller in size and commonly referred to as a donut.
