Visible damage is a clear sign that a tire needs to be repaired or preferably replaced. Every tire inspection should involve a complete visual inspection for damage. This damage can include, but is not limited to, such things as obvious splits, cracks, and punctures in the casing as well as bulges in the sidewall. The presence of any of these signs is a clear indication that the tire is near the very end of its useful life and that it is time to replace it. While punctures may be repaired, many other types of visible damage may be signs of further damage to the tire's interior which could have compromised its structural integrity without the owner knowing.
