What size inner tube does a 12 inch bike take?
Made of sturdy rubber, this tire tube will stand up to all kinds of riding. Make it part of your repair kit for unexpected issues while on the trail. This bike tube fits 12″ tires that are 1.75″-2.125″ wide and has a standard Schrader valve stem for easy inflation.
Is a bike inner tube the same size as the tire?
While your diameter measurement needs to be exact, your width measurement does not. Because inner tubes stretch, they typically come in a range of widths. Some tires have dimensions in millimeters, but the basic measurement structure is still the same: Diameter x Width.
Does inner tube width matter?
No, tubes and tires don’t need to match exactly. Tubes are made from butyl rubber which can stretch. Bike inner tubes will accommodate a limited range of sizes. Larger tubes may be more susceptible to getting pinched between the tire and rim.
Does inner tube valve size matter?
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. Likewise, a tube rated a bit wider than your tyre will usually fit, although it can be awkward to fit one that’s a lot wider than the tyre.
Can I use a bigger inner tube?
Bike inner tubes will accommodate a limited range of sizes. Larger tubes may be more susceptible to getting pinched between the tire and rim. It’s always best to try and match as close as you can, but there is some flexibility. Having a slightly smaller or larger tube will be quite fine.
Can I use an inner tube that’s too narrow for the tyre?
Yes, you can, as long as you don’t go more than one size smaller, or the differential is not too extreme. A 1.25 in a 1.5 is fine. A 1.25 in a 2.25 is likely to have issues with flats. Your LBS will have tubes.
Can you use 1.5 tire 1.75 tube?
All tires of 26″ will fit on a 26″ rim. The diameter 1.5″, 1.75″,1.95″ etcetera have tubes which will fall into the range, ie, tire = 26″ x 1.75″ so you can use a tube in the range of 1.5″ – 1.75″.
