What Size Bike Inner Tube Do I Need? || REI


hey my name is Katie and today we’re gonna be talking about what to size to use with what bike tire there are a whole wide range of tubes to choose from but luckily your tire is going to give you a little bit of guidance 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 and the second number is the width yes as a mountain bike tire this one is a 26 by 2.1 by mountain bike tires can come in 26 27 v or 29 as far as size goes with my 700 by 32 when it comes to actually choosing a tube to go into it you just want to make sure your numbers match so the diameter will always be a single number for my 700 by 32 I’m going to go ahead and choose the tube that says 700 on it but with is a range of numbers when it comes to your tubes so all you want to do is make sure that your tire width fits inside the range of your tube this one for example is a 28 to 32 I could have also chosen arranged like 28 to 35 but in order to make things easier for myself later on when I go to actually put the tube into the tire you want to choose the smallest range that still has your tire width in it that’s all for today on tubes and tires if you’re curious about psi how much you should pump up your tire and a little bit more information on pressure go ahead and check out some of our other videos but until then thanks for watching and we’ll see you next time
