Fitting


Stopaflat tubes are "Size Specific" to a tyre and care should always be taken when matching the tube to the tyre. Please note that our 1.75 sizes will fit a 1.90 standard tyre. Tyre width markings are clearly embossed on the outside wall of a tyre. However there can be variations between tyre manufacturers and tread designs.
