What Size Bike Tube Do I Need? – Inner Tube Sizes

The size of bike tube you need is determined by the diameter and width of your tire. The most common sizes are 26 inches by 1.75 inches, 700c by 23mm, and 29 inches by 2.1 inches. You can usually find this information printed on the side of your tire.

If you’re unsure, you can always bring your old tube with you to the store to compare sizes.

Inner tube sizes for bike tires can be confusing. The first thing to know is that there are two different types of inner tubes, Presta and Schrader. If you have a Presta valve, it will have a small diameter and screw on cap.

A Schrader valve has a larger diameter and a spring-loaded pin in the center. Most mountain bikes and road bikes use Presta valves. The second thing to know is that inner tube size is not synonymous with tire size.

Just because you have a 700c tire does not mean you need a 700c inner tube. In fact, many 700c tires can use a range of different sized inner tubes. The best way to determine what size inner tube you need is to look at the sidewall of your tire.

It should list the recommended range of inner tube sizes. For example, a Continental Grand Prix 4000S II tire might list the following: “700 x 23-25C; presta 42mm valve.” This tells us that the ideal inner tube size for this particular tire is between 23-25 millimeters wide with a 42mm Presta valve stem.

If your bike has more than one type of tire (e.g., road tires and mountain bike tires), then you’ll need to make sure you get the right sizeinner tube for each typeof tire . When in doubt, always err on the side of getting an Inner Tube that’s slightly too big rather than one that’s too small–it’s easier to put less air in an overinflated Inner Tube than it isto tryand inflate an underinflated one .

Do Bike Tubes Need to Be Exact Size?

No, bike tubes do not need to be exact size. In fact, there is a range of sizes that will fit most bikes. The important thing is to get the right width and diameter for your wheels.

You can usually find this information on the side of your tires. As long as you get a tube that is within the range of sizes for your tires, it should work just fine.

How Do You Determine Tube Size?

There are a few different ways that you can determine tube size. The most common way is to use a tube sizing chart. This will give you the dimensions of the tube, based on the inner diameter (ID) and outer diameter (OD).

You can also use a tape measure to measure the ID and OD of the tube. Once you have these measurements, you can then match them up to a standard size on the chart. Another way to determine tube size is by using a caliper.

This tool measures the thickness of the wall of the tube. To use a caliper, you’ll need to know the inside and outside diameters of the tube. You can then plug these numbers into a formula to get the wall thickness measurement.

Once you have this measurement, you can find your tubesize on a standard chart. Finally, you can also ask someone at your local hardware store or home improvement center for help in determining Tube Size .

Does Tube Size Have to Match Tire Size?

No, tube size does not have to match tire size. In fact, many riders find that a larger tube works better with a smaller tire. This is because a larger tube can be inflated to a higher pressure, which helps to prevent flats.

Will a 24 Inch Inner Tube Fit a 26 Inch Wheel?

Yes, a 24 inch inner tube will fit a 26 inch wheel. The inner tube is slightly smaller than the tire so it can stretch to fit.

Tire Tube Size Calculator

There are a few different ways to determine what size tire tube you need. The first is by using a tire size calculator like the one found on BikeBandit.com. Simply enter in the information for your bike, including make, model and year, and the site will provide a list of compatible tires.

Once you have your list of tires, look for the width (in inches) and then find the corresponding tube width range listed next to it. For example, if your bike takes a 26 x 2.0-inch tire, you would need a 26 x 1 3/4 – 2 inch tube. If you don’t have access to a calculator or you’re not sure about the size of your tires, another way to determine which tube size you need is by checking out our handy chart below.

Simply match up your tire’s width with the appropriate tube width range and voila! You’ll know exactly which tube size to get. Tire Width (inches) Tube Width Range (inches)

1 3/8 1 3/8 – 1 5/8 1 1/2 1 1/2 – 1 3/4

Bike Tube Sizes 700C

Bike tube sizes can be confusing, especially when trying to figure out what size you need for your bike. 700C is a common size for road bikes and hybrids, but it’s not the only size out there. Here’s a quick guide to help you choose the right bike tube size for your 700C bike.

The first thing to know is that 700C refers to the diameter of the tire, not the width. That means that a 700C tire will fit on a rim that is also 700C in diameter. The width of the tire varies, though, so you’ll need to know what width tires your bike takes before you buy tubes.

Once you know the width of your tires, finding tubes is easy. Just make sure that the tube says “700C” on it and that it matches the width of your tires. For example, if you have 25mm wide tires, look for tubes that say “25-622.”

If you’re still unsure about which bike tube size to get, just bring along your old tube or measure it yourself with a tape measure. Then head to your local bike shop and they’ll be able to help you find the right size tube for your 700C bike!

What Size Inner Tube Do I Need for 700X38C

If you’re riding a 700c road bike and want to know what size inner tube to get, the answer is 700x38c. This size inner tube will fit a 700c wheel with a 38mm tire. If you have a different sized tire, you’ll need a different sized inner tube.

Here’s a chart that shows what size inner tube you need for various tire sizes: Tire Size Inner Tube Size 700×18/23c 28-32mm Presta Valve

700×25/28c 32-40mm Presta Valve 700×30/32c 40-47mm Presta Valve

Does Inner Tube Width Matter

There’s a lot of discussion out there about whether or not inner tube width matters. The short answer is: yes, it does! Here’s a more in-depth look at why:

Inner tubes typically come in two widths – 26mm and 28mm. The difference may not seem like much, but that 2mm can actually make a big difference when you’re riding. Wider tubes provide more contact with the road, which results in better handling and stability.

They also help to absorb shocks better, making for a smoother ride overall. If you’re an experienced rider who is looking for a little bit of an edge, then wider inner tubes are definitely worth considering. However, even if you’re just starting out, they can still be a good option as they’ll help to make your rides more enjoyable from the get-go.

Bike Tire Tubes

Bike tire tubes are one of the most important parts of a bicycle, and yet they are often overlooked. Tire tubes keep your tires inflated and help to protect your rims from bumps and potholes. They also make it possible to change your tire’s width without having to replace the entire wheel.

There are two types of bike tire tubes: inner tubes and outer tubes. Inner tubes are made of rubber and fit inside your tire. Outer tubes are made of metal or plastic and fit over your rim.

Both types of tube have a valve stem that sticks out so you can inflate them. When choosing bike tire tubes, you need to consider the size of your tires and wheels, as well as the type of riding you’ll be doing.

Bike Tubes

If you ride a bike, it’s important to know how to change a bike tire. Bike tires go flat for all sorts of reasons – from punctures to simply running over glass. And, when your bike tire goes flat, you’ll need to change it.

Here’s how to do it: First, you’ll need to remove the wheel from the bike. If you have a quick release lever, this is easy to do.

If not, you’ll need a wrench. Once the wheel is off, take out the old tube. To do this, first remove the tire from the wheel.

You can do this by hand or with a tire lever (we recommend using tire levers). Once the tire is off, find the valve stem and unscrew it. Then gently pull out the tube – being careful not to damage the valve stem in the process.

Now it’s time to put in the new tube. Start by putting a little bit of air into the new tube – just enough so that it holds its shape but isn’t too full (about halfway full is good). Then thread one end of the tube around the circumference of the wheel and tuck it under itself so that it’s secure (this will help prevent pinching when you put on the new tire).

700C Inner Tube

A 700C inner tube is a bicycle inner tube that is designed to fit a700C wheel. This size of inner tube is often used on road bikes and hybrids. The 700C designation refers to the approximate outer diameter of the tire in millimeters.

A typical 700C tire has an outer diameter of around 622mm. Inner tubes are made from either butyl rubber or latex, with butyl being the most common. Butyl rubber inner tubes are less expensive and hold air better than latex tubes, but they’re also heavier.

Latex inner tubes are lighter weight and provide a smoother ride, but they can be more difficult to install and are more expensive. When purchasing a new inner tube, it’s important to know the width of your tire as well as the type of valve you have (Presta or Schrader). Presta valves are typically found on road bikes and have a small diameter opening that requires a special adapter for use with an air pump.

Schrader valves, which look similar to those found on car tires, are more common on mountain bikes and hybrid bikes. Someinner tubes come equipped with removable cores that allow you to change out the valve without having to replace the entire tube.


If you’re new to biking, you might be wondering what size bike tube you need. The good news is that there are only a few things you need to know in order to find the right size inner tube for your bike. In this blog post, we’ll cover everything you need to know about bike tube sizes so that you can get back on the road (or trail) as soon as possible.

The first thing to keep in mind is that there are two types of bike tubes: presta and schrader. Presta valves are typically found on road bikes and schrader valves are usually found on mountain bikes. If you’re not sure which type of valve your bike has, just take a look at the existing tube or ask someone at your local bike shop.

Once you know which type of valve your bike has, finding the right sized tube is a pretty straightforward process. If you have a presta valve, you’ll need to measure the diameter of the valve stem in order to find the right sized tube. On most presta valves, this measurement will be either 6mm or 8mm.

Once you have this measurement, simply match it up with the corresponding width of inner tube (i.e., if your valve stem is 6mm wide, look for a 26″x1-3/8″ tube). Schrader valves are a bit easier to work with because they all use standard sizing (i.e., 26″x1-3/8″). Of course, there’s more than one way to skin a cat and some people prefer using different methods for finding their ideal inner tube size.

If measuring valve stems isn’t your thing or if you’re still unsure about what sizetube would be best for your bike, don’t hesitate to ask someone at your localbike shopfor help.
