It is inadvisable to use non-tubeless tyres without an inner tube as there is otherwise a risk of tyre blow-off. Tubular tyres Used primarily for racing, 700 by 38 bike wheel computer measurement tyres must be fixed to coomputer appropriate rim using glue, wwheel or adhesive tape.

Although these size designations are mathematically equal, they refer to different size tires, which are NOT interchangeable. It is dangerous to generalize when talking about tire sizing, but I would confidently state the following:. If two tires are 700 by 38 bike wheel computer measurement with sizes that are mathematically equal, but one measurementt expressed as a decimal and the other as a fractionthese two tires will not be interchangeable.

Suppose you are in the market for a high-performance x 25 tire; you might reasonably investigate catalogues and advertisements to try to find the lightest available.

If the Pepsi Tire Company and the Coke Tire Company had tires of equal quality and technology, but the Pepsi was actually a marked as a 25, the Pepsi tire would be lighter than the accurately-marked Coke This would put Pepsi at a competitive advantage.

For example, a x 20 C road tire vike be a ; a x 38 hybrid tire would be a The width difference between these sizes would make them less-than ideal replacements for one anotherbut any rim that could messurement one of them would work after a fashion with the other.

If you pull the beads apart and measure the total width from bead to bead, it should be approximately 2. If its too wide for the rim, there's an increase risk of sidewall wear from brake shoes, and a greater risk of loss of control in the event accessories computers a sudden flat.
