175/185x16 Thickened Inner Tube
A thicker radial Blockley butyl inner tube we produced to fit tyre size 185R16 size, and nothing else.
We produce this inner tube because we make a 185VR16 tyre and need a good quality wholesome tube to suit. In other words a tube that is only made for a 185R16 tyre and not a host of other sizes. This way the tube will not be crumpled up from being too big, and will not have to stretch into the void getting thin.
In addition for the 185VR16 tyre note we also make an even thicker "600/650x16" tube which many like, which is available with a rubber stem as well as a nickel plated metal "race" stem.
