Are all bike inner tubes the same?

Asked by: Alma Lopez

Your inner tube needs to fit the wheel’s diameter and also the width of the tyre fitted, so there are two significant measurements to get right. Let’s start with diameter – make sure you’ve got the right size inner tube for your wheel’s diameter or you’ll find it difficult to fit.

What size inner tube do I need for my bike?

Checking the Inner Tube Size You Need



The best way to check what size inner tube you need is to look on the sidewall of your tyre. Tyre manufacturers print the size on the sidewalls, so look out for numbers such as ‘700x23c’ for a road bike, or ’26×1. 75′ which is for mountain bikes.

Are all inner tubes the same size?

Size. Inner tubes vary in size depending on the circumference of the wheel, and the width of the tyre: Wheel Diameter/Circumference: Depending on whether your bike is a road bike, touring bike, mountain bike, or child’s bike, the diameter and circumference of the wheel can vary.

How do I choose a bike inner tube?

If you check along the sidewall of your tire it'll tell you your size. So for example this my road bike tire is 700 by 32 that first number is the diameter of the tire.

Are bike tubes different sizes?

Sizes such as 26, 24, 20, 27.5, 29 and 700c are common tire diameters. The second number (after the X) is the width of your tire. The range for widths is usually between 1 and 3 inches. For example, a 26 x 1.75 size means the tire diameter is 26 inches and the tire width is 1.75 inches.

Can a 26 inch inner tube fit a 27.5 wheel?

26″ tubes work perfectly well with 27.5″ wheels.

Does inner tube width matter?

All inner tubes will come with a recommended range for tyre width – for example 700 × 20–25 for traditional road tyres, 700 × 25–32 for wider road tyres. A narrower inner tube will balloon out to fill a tyre a few millimetres wider than its recommended width – but don’t take it too far or it might explode.

What is the average size bike tube?

What does 700C mean?

700C tires



The “700” refers to the rough outer diameter of the tire, although the actual outer diameter will vary greatly, depending on the type of tire and tread pattern. The “C” means NOTHING; it does not stand for “centimeters.” Think about it–a 700-centimeter tire would be HUGE, over 21 feet tall!

What means 700x40c?

700x40c is the measurement of your bicycle tire and is sized according to what used to be known as the ‘French system’. ‘700’ is the nominal diameter of your tire, measured in millimeters. ‘x’ just means multiplied by. ’40’ is the second number and is the nominal tire width, also measure in millimeters.

Is a 28 inch tire the same as 700C?

28”/700C/29er



The tyres can differ, but the 28”, 700C and 29er are all the exact same rim diameter. The 700 markings will be followed by the width in mm, and the 28 or 29 markings will be followed by the width in inches. This is the most common wheel size, so look out for familiar markings (such as 28×1.

IS 700C and 29er the same?

29″ (ISO size 622) is actually the same rim diameter as 700C, although most 29″ tires will not fit 700C road rims because they’re too wide.
