Radial pencil shaped bulge in the sidewall of a radial tire.
Wider than normal wire spacing. A tire with a repair may show this condition soon after being repaired, or the condition may arise somewhere along a body ply that has been damaged — not necessarily in the repair area.
Determine the cause of the bulge. Repaired tires can often be returned to service on dual positions unless the bulge height exceeds 3/8" when inflated. If the cause of the bulge is not a repair or damage, contact the tire manufacturer.
