I noticed a small tear in the centre of the rear tyre (OEM Battlewing 1 year old) It is a small tear, less than 1 cm (three-eights inch) long and runs horizontal in the centre, where the tyre touches the ground. The tyre still has 6mm thread on it and the depth of the cut is around half the thickness of the thread. I'm planning a longish ride next month and not sure if I should replace the tyre before that ride. I know that the safest answer would be to replace the tyre. But I'm finding it difficult to just replace it, knowing that it still has 6mm thread and that the cut is small and only around half thread deep. Any shared experiences would be appreciated.
