Can I use a smaller tube in my bike tire?

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.

Does tube size match tire size?

The tube should match the tire size diameter closely. However, tires that are close in bead diameter may use the same inner tube. For example, an inner tube for an ISO 630 tire (27-inch) will also fit an ISO 622 (700c) tire.

What are tires with tubes called?

A tubular tire – also called a sew-up, tubie or tub – is exactly what it sounds like: a combination, one-piece tire/tube. You have to mount a tubeless tire to a special tubular rim – typically this is done by gluing the tire to the rim or using a special adhesive rim tape.

What happens if your inner tube is too big?

If the inner tube is a lot larger than the tire, it will cause folds and wrinkles inside the tire, which may affect your ride. If you have a tube that is only a little bit larger, then it probably won’t make a difference. While larger tubes will weigh more, they will retain air better.

Do tubeless tires go flat?

It’s pretty rare to get a flat tire when you have a tubeless setup. The sealant inside your tires will quickly seal small holes and cuts to keep you rolling on the road or trail. However, flats are always possible – even with tubeless.

Why are tubeless tires better?

Tubeless tires offer better traction, allowing you to corner better and climb more easily- Because you don’t have to worry about pinch flats, you can run tubeless tires at a much lower air pressure than tubed tires. Usually, about 10 psi lower is safe.

How do I know what size inner tube I need?

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.
