Why do my bike tires feel flat?

You don’t actually know your pressure And gauge quality varies; it may be off only by a few PSI for a standard road pressure, but we’ve seen pumps that are off by 10-15PSI. The good: Most gauges are at least consistent even if they’re not totally accurate. So at least you’re inflating to the same pressure each time.

Is 40 psi too high for tires?

Normal tire pressure is usually between 32~40 psi(pounds per square inch) when they are cold. So make sure you check your tire pressure after a long stay and usually, you can do it in the early morning.

Can I use a car tire pump on my bike?

The long answer: The reason you can sometimes use an automotive air-pump on a bicycle tire/tube is because they share an identical valve. (See: Schrader valve/Schrader tube in the Terminology Index). If you have this type, you will definitely be able to get air into your tubes in a pinch.

What air pressure should tires be at?

On newer cars, the recommended tire pressure is most commonly listed on a sticker inside the driver’s door. If there’s no sticker on the door, you can usually find the specs in the owner’s manual. Most passenger cars will recommend 32 psi to 35 psi in the tires when they’re cold.

What is a Presta valve on a bike?

The Presta valve (also French valve (FV) or Sclaverand valve) is a valve commonly found in high pressure road style and some mountain bicycle inner tubes. It comprises an outer valve stem and an inner valve body. A lock nut to secure the stem at the wheel rim and a valve cap may also be present.
