Sometimes you might find yourself in a situation where your bike will lose the amount of air it requires, and you will not be able to do much about it because you won’t have a bike pump available.

In situations like these, you will have to do what you have. And, if, by some miracle, you can manage to get your hands on a car tire pump, you’re all set.

Although unconventional, you can sometimes pump your bike tire with a car pump. But does that mean you should do it? Well, the answer is a bit complex, so without further ado, let’s get on with the discussion.

Can I Use a Car Tire Pump on My Bike?

To answer your question- yes, you can. If you are in a pinch and your tire needs to get inflated urgently, you can use a car tire pump on your bike. But only some bike valves are compatible with car tire pumps, so it is better to purchase a bike pump.

Should I Use a Car Tire Pump on My Bike?

Some things are best avoided. Just because you can do them does not mean you should and using a car tire pump to inflate a bike is one of those things.

Since most car tire pumps do not come with the option of adjusting the air pressure, you can easily over-inflate and burst it. That will do you more harm than good, so it is best only to use car tire pumps if you need to.

Things To Remember Before Using a Car Tire Pump on Your Bike

Even though you can use a car tire pump on a bike from time to time, you need to remember things before doing so. These are just some things you need to be cautious about because if they are neglected, you might have a bigger problem than just a deflated bike.

Not All Car Tire Pumps Can Be Used for Bikes

First, you need to remember not all bikes can be inflated using car tire pumps. Only bikes with certain valve types can be, and I will get more into that in the how-to section.

Just keep in mind that forcing your pump onto the wrong valve might damage the valve, and it is better to have a bike pump handy if the bike isn’t compatible.

Car Tire Pumps Have Different Air Pressure

Another thing you will need to remember is that car tire pumps don’t always have the same air pressure as bike pumps.

Often, car tire pumps have a higher air pressure and higher volume, which can be hard to regulate without a pressure gauge. This is especially true if you are trying to inflate your bike at a gas station because their air hoses are usually unregulated.

Using an unregulated air hose can be very dangerous as your tire might get over-inflated very quickly and might even burst before you get a chance to react. So, it is best to get a bike pump or use a car pump with a pressure gauge and regulator.

How To Use a Car Tire Pump for A Bike Properly?

As I have previously mentioned, you can sometimes use a car tire pump to inflate your bike tire. It’s just one of those things that you will never need in your life, or you will need for one day. But when you need it, you will be glad you know how to do it.

Knowing how to use a car tire pump for a bike is a valuable skill to have up your sleeve. After all, it can save you from suddenly being stranded in the middle of nowhere. However, if you don’t know how to do it properly, you might get into big trouble.

And I bet you don’t want to walk around with a deflated or burst tire, so let’s see what some of the ways you can pump your tire are:

Check The Valve

Remember when I said only bikes with certain valve types could be inflated using a car tire pump? Well, it’s time to discuss more on that.

So, bikes mainly have three valves: the Schrader or American valve, the Presta or French/ Sclaverand valve, and the Woods or English/Dunlop valve. Of these three, only the Schrader valve is compatible with car tire pumps as cars also have Schrader valves.

But how do you recognize a Schrader valve? In the case of bicycles, Schrader valves are most seen in mountain bikes. Their key feature is that they have a shorter and thicker nozzle than the other valves and are secured by rubber caps that go over the opening.

If your bike has a Presta valve which is commonly seen in road bikes, there is a way you can use a car tire pump as well. Presta valves have long, and narrow valves secured by caps, and they aren’t compatible with car pumps. So, you will have to use an adapter that will fit between the valve and the air nozzle and create a seal that will allow you to inflate it.

Check The PSI

Pound Per Square Inch (PSI) refers to the amount of air pressure required for the bike to run smoothly. If you are unsure about the PSI of your bike, check the side of the tire where it touches the rim; the recommended air pressure is usually written there.

To check the PSI of your bike, attach it to a pressure gauge so that you can avoid over-inflating it. But if you don’t have a pressure gauge, you can inflate it slowly until the tire is firm yet slightly squeezable. Although measuring by hand won’t give you accurate results, it will provide you with a rough estimate.

And always remember, it is better to slightly under-inflate the tire than to over-inflate it.

Adjust The Pump’s Air Pressure

Only use a car tire pump that has adjustable air pressure. This is because it is very easy to over-inflate and burst the tire. Adjusting the stress will make your life easier as you won’t have to worry about the tire popping.

However, if you really can’t find an adjustable pump, and you are in a pinch, inflate the tire a little at a time, and keep it a tad bit under-inflated to be on the safe side. Also, get a pressure gauge and monitor it to make sure you remain on the recommended PSI range.

Inflate The Bike

If you have a Schrader valve, follow these steps to inflate the tire.

  • Remove the rubber cap sealing the opening.
  • Attach the nozzle of the car pump to the opening of the valve.
  • Slowly inflate the tire and keep an eye on the pressure.
  • Once inflated, take off the pump and put the valve cap back on.

If you have a Presta valve, follow these steps to inflate the tire.

  • Take off the rubber cap.
  • Unscrew the nut and attach the adapter to the valve.
  • Connect the nozzle of the pump to the adapter.
  • Inflate the tire a little at a time and monitor the pressure.
  • Take off the pump and adapter, screw the nut, and put the cap back on.

 

Conclusion

To conclude, yes, you can use a car tire pump on your bike, but it is not recommended. But that does not mean that you shouldn’t learn how to do it. It’s a skill that could save you from a sticky situation, and rest assured, you will at least be able to get home safely by knowing how to do it.

So, what are you waiting for? Acquire the skill of inflating your bike tire with a car tire pump right away!
