How Do You Know When to Fill Your Bike Tires With Air

Inflating your wheel tires is a elementary and painless chore, as long as yous know what tools you need. Identify your valve type with the methods beneath and pump accordingly.

1. i

   A Schrader valve is as well called an American valve, or a car valve. The valve stem is surrounded past a threaded valve core; to press down on the stem, you need to use a tool like a pen cap or your thumbnail.^[1] Schrader valves are typically wider in bore and shorter than Presta or Woods valves. They're usually plant on cars, less expensive bikes and mountain bikes. To open a Schrader valve, simply unscrew the rubber cap at the acme.

2. 2

   Figure out the recommended PSI for your tires. This is normally on raised print on the side of your bike tires and volition consist of a range. Don't permit your PSI become any lower than the lowest number; the high number is the recommended maximum PSI.

3. iii

   Locate a pump. If yous don't already have 1, endeavor to use a gas station pump, or borrow ane from a friend.

   • If you have a Schrader valve, you're in luck - you won't need an adapter to use a gas station pump. Inquire the attendant for a pressure guess and inflate your tires in small bursts, checking the pressure afterwards each ane. Gas station pumps are extremely high pressure, and you can popular your tires if you're not conscientious.
   • If yous're using a cycle pump with ii openings, the larger one is meant for the Schrader valve.
   • Smart pumps with one opening volition automatically suit to arrange a Schrader valve.^[2]
   • A pump with ane opening may require yous to contrary an internal safe stop to fit a Schrader valve. Unscrew the face cap and find the rubber stop. The larger end should be facing out for a Schrader valve.

   Inflate the tire. Unscrew the safe cap on elevation of the valve and put it somewhere safe, like your dorsum pocket. Yous don't want to lose it.

   • Put the pump on the valve. If there's a lever almost the nozzle, make sure it's in the open position (parallel to the nozzle) when you're putting it on the valve; snap the lever down into the closed position (perpendicular to the nozzle) when it'southward on. Proceed an middle on the PSI equally you pump.
   • Flip the lever support to remove the pump, so quickly return the rubber cap to the valve.

   To deflate a tire with a Schrader valve, simply printing on the springy valve stalk with a fingernail or other pocket-sized tool until all the air escapes. ^[3]

1. 1

   The Presta valve, likewise called a Sclaverand or French valve, is commonly found on high-end route bikes. Presta valves are longer and narrower in bore than Schrader valves, and feature an external valve stalk that is protected past a valve cap, instead of beingness surrounded past a valve core.^[4]

2. 2

   Open the valve. To open a Presta valve, unscrew the dust cap at the top and put it somewhere safety. And so, loosen the small brass cap on the valve stem - it won't come off completely, but you should be able to raise it a bit. To check if y'all've loosened the bras cap enough, printing on the valve stalk. If you lot can hear air escaping in a sharp burst, yous've loosened information technology enough.^[5]

3. 3

   Figure out the recommended PSI for your tires. This is usually on raised print on the side of your bicycle tires and will consist of a range. Don't let your PSI go whatsoever lower than the everyman number; the high number is the recommended maximum PSI.

4. 4

   Locate a pump. Try to use a gas station pump, or borrow i from a friend. You lot tin also purchase pumps at your local bicycle shop.

   • To use a gas station pump on a Presta valve, you'll demand a Presta adapter. This is a pocket-size cap yous tin screw onto a Presta valve to essentially turn it into a Schrader valve.^[6] Some older bike pumps might also require yous to take a Presta adapter. Y'all tin can purchase i from your local wheel shop. When using a gas station pump, ask the attendant for a pressure gauge and inflate your tires in pocket-size bursts, checking the pressure after each ane. Gas station pumps are extremely high pressure, and you tin popular your tires if you're not careful.
   • If you're using a bike pump with two openings, the smaller 1 is for a Presta valve.
   • Smart pumps with one opening volition automatically accommodate to conform a Presta valve.
   • A pump with one opening may require y'all to reverse an internal rubber stop to fit a Presta valve. Unscrew the confront cap and find the rubber end. The smaller end should be facing out for a Presta valve.

5.

   Inflate the tire. Open the Presta valve by unscrewing the dust cap and loosening the smaller brass cap.

   • Put the pump on the valve. If there'south a lever near the nozzle, make sure it's in the open position (parallel to the nozzle) when y'all're putting information technology on the valve; snap the lever downwardly into the airtight position (perpendicular to the nozzle) when it'south on. Keep an eye on the PSI as y'all pump.
   • Flip the lever back upwardly to remove the pump, and screw the contumely cap closed.
   • Replace the dust cap.

Add New Question

• Question

  How do I know when I have pumped plenty air into the tire?

  

  The tire should feel firm - you shouldn't be able to pinch the sidewalls of the tire together very much. On a mountain bike tire, yous should be able to push in past about a centimeter or so. Check the sidewall of the tire to notice the minimum and maximum pressure values and apply the guess to go the force per unit area between these values.

• Question

  How do you pump upward a tire on the road?

  

  Don't. You volition be hit by a machine. Pull to the side of the road and then follow the steps shown here. You don't demand to know the verbal pressure level recommended for your tires. Simply press down on the tire with your finger and pump until it feels firm, but with a little give left in it.

• Question

  What happens if I pump my tire upwardly too much?

  

  Should you pump the inner tube up too much, it will likely explode inside the tire. Bank check the sidewall of the tire to find the minimum and maximum pressure information technology tin handle.

• Question

  What should I use to seal the rim to the tire?

  

  In that location is no need to utilise anything to seal the tyre to the rim with a clincher setup (one where you have a split inner tube). With a tubeless setup, the tyre is stock-still to the rim.

• Question

  Why practice my tires go down after pumping them upward?

  

  Assuming the tubes are non erstwhile, at that place is perhaps a pocket-size hole in the tube, and possibly something in the tire itself made the pinhole. Older tubes, especially cheap ones, are porous and don't retain pressure level well after several months.

• Question

  Is at that place a way to get it out if I pressed the Schrader valve into the tire ring by accident?

  

  You'd have to unseat 1 dewdrop of the tire and piece of work the tube around slowly to slide it to the pigsty with the bicycle off the bike.

• Question

  What is the tire valve for a Mate bike?

  

  Pretty sure it has Schrader valves. Presta valves are non equally common, and are mostly used on higher-end competitive road bikes.

• Question

  How do I inflate a bike tube with no pin on information technology?

  

  While there are tires without valves, it isn't likely that you'd have one without knowing, as they tend to be heavy, expensive and most of all don't go flat, they are filled solid. Brand sure your valve is non obscured past a dynamo or some other part of your cycle.

• Question

  Is there any danger in inflating to the maximum recommended pressure betoken or should I leave information technology betwixt minimum and maximum recommended pressure level points?

  

  Jayden Watford

  Customs Answer

  There is no danger when inflating to the maximum point merely practise not exceed this amount. Leaving it between the points is also an choice if you notwithstanding fear pumping it to the max.

• Question

  I bought a paw pump, but where do I put the pivot?

  

  The wheel of the back tire has a small cap, like a toothpaste cap. Pull it off and put the pin in that location.

• If you purchase a pump, get one that makes sense for you. Many are the stand-up variety, where you lot stand on office while the handle goes up and down. Others are more compact--"mini" according to a number of companies' labels--which tin be handy when you are on the become.

• Proceed rail of your valve caps. If you lose them, the valves can become dirty, leading to pumping difficulties, and will lose air more quickly.

• Check your air pressure in a few days to brand sure that your tires are however properly inflated. If they are not, you may want to replace your tires or inner tubes.

• If yous cannot make up one's mind the type of your valve, take a photo of it. Bring it in with you when you are going to get your wheel pump.

• Periodically check the pressure as your tire is existence inflated. Some newer bicycle pumps will take a gauge built in that tells yous the pressure of your tire equally you are pumping the air into the tire, however be careful not to pump also much the tire might explode

• If you're unsure about how much air should be put in or y'all don't have a pressure indicator on your pump, only fill the tires until they are business firm, nevertheless so you can nonetheless squeeze them always so slightly. If you retrieve it'due south done, you're probably right.^[9]

• Proceed newly inflated tires from abrupt objects, and vice versa.

Things You'll Need

• A bicycle
• Access to a bike pump
• Possibly a valve adapter
