What Causes Sidewall Bubbles in Tires?

When the bond between the different tire components is compromised, bubbles can form in the sidewalls. tire image by timur1970 from Fotolia.com Tires are composed of rubber compounds, plies of fabric cords, steel wire and adhesives that hold it all together. The plies of fabric cords and the steel wire provide the structure and shape of a tire–the rubber is stretched over the cords and wire, forming the bulk of a tire. If the strength of the bond between the rubber compounds, the fabric cords and the steel wire is compromised, bubbles can form in the tire’s sidewalls. Defects During the manufacturing process, if the rubber compounds, plies of fabric cord, steel wire or adhesives are contaminated, or if the adhesives don’t bond correctly to the rubber, plies and wire, the plies and wire can separate, resulting in air pockets. Such bubbles will form within the first six months of the tire’s use. Underinflation Underinflated tires are more flexible than correctly inflated tires. When tir
