Holes and damages on the tyre side walls cannot be repaired. Do not use the quick
tyre repair kit if damaging is due to running with flat tyre.
Repairs are not possible in case of damages on the wheel rim (bad groove
distortion causing air loss). Do not remove foreign bodies (screws or nails) from the
tyre.
