What is a VSB sidewall?
Puncture repairs are limited to the center of the tread area. If there are punctures or damage in the shoulder or sidewall of the tire, it is not repairable. Not all tires can be repaired.
Road hazards include potholes, debris, and curbs, which can leave a cut or a puncture in the tire. The damage may be immediate, making the tire go flat or explode, or it may be long-lasting. The latter will expand and eventually deflate the tire fully, causing a tire sidewall blowout.
