What happens if you drive over 50 on a spare?

You should not drive over 50 mph and no more than 50 miles with a donut-type spare tire. Driving for long distances on a spare tire can potentially cause damage to other car parts, including the transmission.

Why is spare tire pressure so high?

According to TireRack, donut spares have a higher air pressure because of their smaller dimensions. That’s right, a donut spare has about half the contact surface of a full-size tire. To compensate for the reduced surface area, the air pressure in the tires needs to be higher than a full-sized tire.

Do spare tires have pressure sensors?

The spare tire is not equipped with a TPMS sensor, so the TPMS light on the dash comes on because it cannot get a reading from that tire. The light will stay on until you have the normal wheel replaced.

How do I know if my spare tire is good?

Visually check the condition. Whenever you check the spare tire, look for cracking in the sidewalls and in between the tread blocks. If there are light cracks that the edge of a penny don’t catch on, you are alright to use the spare tire and just have it replaced after usage.

Can I put air in a spare?

A matching full-size spare is just like the tires you are using on your vehicle. These should be inflated with the same air pressure as your running tires. In fact, they should be incorporated in with the tire rotation, so that they wear out evenly along with your regular tires.

Does the spare tire have a pressure sensor?

Is a 20 year old spare tire safe?

A 20-year old spare tire is not safe. Car manufacturers recommend replacing tires every six years, and no more than every 10 years, regardless of their remaining tread. Driving on old tires has been the cause of accidents and fatalities.

Why do spare tires have a max speed?

But because the spare is smaller than the opposing wheel on the same axle, it must turn faster to keep up with the speed of the car, making the differential work to account for the variation. It’s as if the car is constantly in a turn.

Is it OK to put a spare tire on the front?

If you have absolutely no other options, and you’re only driving a short distance (only a few blocks), then you’re usually safe attaching a front spare tire—just make sure you drive defensively and refrain from taking any further risks.

How much air should I put in my spare tire?

If you have a full-size spare, the air pressure should be the recommended pressure on the side of the tire; typically between 32 and 38 PSI. If you are looking for an easy to read and accurate tire pressure gauge try the ProReady Digital Tire Pressure Gauge; which you can buy here from Amazon.

What is the PSI of a donut spare tire?

The air pressure or PSI of a donut spare tire is 60 PSI. If you have a full-size spare, the air pressure should be the recommended pressure on the side of the tire; typically between 32 and 38 PSI.

What should the tire pressure be in my car?

In most cases, it should be inflated at 60 psi. It’s a good idea to check the pressure in your tire on occasion, just so you do not try to use it one day only to find out that it doesn’t have enough tire pressure. Make sure you have a spare that’s always ready to go so you aren’t stranded in the middle of nowhere.

How often should you check the tire pressure in your spare tire?

It is recommended that you check the tire pressure in your spare tire every tire rotation; or every 6,000-8,000 miles. Even though your spare tire isn’t doing anything, air can still leak out. Then, when you need it the most, it will not be there for you. Carrying a small air compressor with you may not be a bad idea.
