Can You Use A Hand Pump to inflate car tires?

Mar. 27, 2024

Maybe you've recently noticed that your tires are looking a little low and you're looking for a way to fix the problem. If you've investigated your garage and found a hand pump, I have good news for you: it may be possible to inflate your car tires.

In this guide, I'll talk a little bit about tires, I'll explain how a bike pump can help you, and I'll give you a step-by-step guide to using a hand pump to inflate your tires.

Tire Pressure

Inside your tires, there is "air" that makes the rubber expand. Modern tires contain this air as well as the tire's bead, liner and bead filler.

There is a small passage on the side of the tire for air to pass through, called a valve stem. The valve is designed in such a way as to allow air in but not allow air out.

As a result, you are left with pressurized air inside. This is because when you pump air in, it just keeps coming in and there is no place for it to escape. This is the same reason that balloons expand when you blow them up.

Correct Tire Pressure

The correct tire pressure varies from car to car and also depends on the location of the tires. In many cases, the front two tires require a different pressure than the rear two.

How do you find the correct pressure? This is the manufacturer's recommendation. If you open the driver's door and look at the door frame, you should find a sticker. This sticker will indicate the psi that is best for your tires.

The "Right" Way to Inflate

Typically, you will inflate your tires using an air compressor and a special inner tube attachment. The compressor pumps air through the attachment into the open stem of the tire.

Many of these tools also have a built-in pressure gauge. It will constantly tell you what the internal psi of the tire is so you know when to stop pumping.

If there is no gauge built into the pump, you will need to remove the pump and manually check the tire pressure periodically. After all, over-inflation is just as dangerous as under-inflation.

When to use a pump

After explaining the whole process, you may be wondering what a bicycle pump is for. Well, there are a few reasons to try using a bike pump to inflate your car tires.

It's an emergency

If you get stuck somewhere and your tires are in desperate need of air, you may have to grab a bike pump. This will give you enough temporary pressure to get it home or to the nearest gas station to fill up.

You don't have a compressor

Some people simply don't have access to a compressor and they need to fill up their tires. If you need to get to work or plan to drive somewhere else to use a compressor, you may be tempted to grab a pump - especially if that's all you have access to.

Which leads to the million-dollar question: Can you use a bicycle pump to inflate your car tires? The answer is yes. In fact, I've done it myself, so I can attest that it works. However, it's only for the patient person. What may take two dozen pumps to achieve on a tiny bike tire may take 200 pumps on a car tire.

Professional Advice

There is a great product that can help you avoid this disaster in the future. It's a portable tire inflator for car tires.

I personally own one and it has saved me in some tricky situations. Instead of spending 20 minutes manually inflating your tires, you can just put this tool on your tires and get perfect psi in a minute. if you think you might be in the same situation again in the future, you might want to pick one up today.
