What are Bike Tire Tubes

Bike tire tubes are an essential part of a bicycle. They provide the air pressure that keeps the wheels inflated and helps to absorb shock. There are different types of bike tire tubes, each with their own benefits and drawbacks.

The most common type is the Presta valve, which is often used on road bikes. This type of tube is easy to inflate and has a small opening that helps to prevent air leaks. However, Presta valves can be difficult to close if they are not properly aligned.

Another type of bike tire tube is the Schrader valve, which is commonly used on mountain bikes. This type of tube is easier to close than a Presta valve, but it can be more difficult to inflate due to its larger opening.

How To Choose Inner Tubes – GCN's Guide To Road Bike Inner Tubes

Bike tire tubes are usually made of rubber and are inflated with air. They help to protect the inner workings of your bike from the elements and provide a smooth ride. If you get a puncture, you’ll need to replace your bike tire tube.

Here’s a quick guide on how to do it.

What Size Inner Tube Do I Need for 700X38C

When it comes to inner tubes, one size does not fit all. Just as there are different sizes of tires, there are also different sizes of inner tubes. So, what size inner tube do you need for your 700x38c tire?

The first step is to identify the type of valve on your tire. There are two types of valves: Presta and Schrader. Presta valves are typically found on road bikes, while Schrader valves are found on mountain bikes.

If you’re not sure which type of valve you have, take a look at the stem. Presta stems are thinner and have a screw-on cap, while Schrader stems are thicker and have a spring-loaded valve. Once you know the type of valve you have, it’s time to determine the right size tube.

Inner tubes are typically categorized by width (e.g., 18-22mm) and length (e.g., 60mm). The width of the tube should match the width of your tire (700x38c), while the length will vary depending on the depth of your rim. For example, if you have a deep-dish rim, you’ll need a longer tube than someone with a shallower rim.

Do Bike Tires Need Tubes?

No, bike tires do not need tubes. Tubes are only necessary if you are using a rim that is not compatible with tubeless tires. If you have a tubeless-compatible rim, you can simply install your tire without a tube and seal it with some sealant.

What is the Purpose of a Tire Tube?

A tire tube is an inflatable rubber product that fits inside a tire to hold air. It helps give the tire its shape and provides a cushion for the ride. It also helps keep the tire inflated and prevents it from going flat.

How Do I Know If My Bike Tire Has Tubes?

Assuming you’re talking about a bicycle with pneumatic tires, there are a few ways to tell if your bike has tubes or not. The easiest way is to look at the tires themselves. If you see a large metal object (usually called a “valve stem”) protruding from the tire, then it definitely has tubes.

If you don’t see anything sticking out of the tire, it might still have tubes…or it might not. To be sure, you can always check with the manufacturer of your bike or the person who sold you the bike in the first place. They should be able to tell you for sure whether or not your bike has tubes.

Are Tubes Better Than Tubeless?

The debate of tubes versus tubeless has been going on for years in the mountain biking community, with no clear winner. Both have their pros and cons, so it really comes down to personal preference. Here’s a breakdown of each option:

Tubes: Pros: Tubes are cheaper and easier to install than tubeless systems. They also weigh less, so if you’re racing, every ounce counts.

And if you do get a flat, it’s usually an easy fix – just put in a new tube and you’re good to go. Cons: The biggest downside to tubes is that they can puncture more easily than tubeless tires. That’s because there’s nothing sealing the tire to the rim, so any sharp objects can penetrate the tire and cause a flat.

This is especially true if you ride in rocky or rooty terrain. Another drawback is that they don’t hold air as well as tubeless tires, so you may have to pump them up more often. Tubeless:

Pros: Tubeless systems provide a better seal between the tire and rim, which makes it harder for sharp objects to puncture your tire and cause a flat. They also hold air better than tubes, so you won’t have to pump them up as often. And because there’s no tube, you can run lower tire pressures without worry of getting a pinch flat (when the tube gets pinched between the tire and rim).

This not only gives you better traction but can also help protect your rims from impact damage. Cons: The biggest downside to tubeless systems is that they’re more expensive than tubes and can be harder to install (although once you get the hang of it, it’s not too bad).


Bike tire tubes are inner tubes that sit inside your tire and hold air. They typically have a valve stem sticking out of one end that you use to inflate the tube. When you get a flat tire, it’s usually because the tube has punctured and lost air.

You can patch up a hole in a bike tire tube, but if it’s too big or there are too many holes, you’ll need to replace the tube.
