Bulges in tyres can occur when the sidewall becomes damaged – which is often caused by impact from ‘kerbing’ or from pot holes in the road.
The structrual integrity of the tyre sidewall is weakened and the internal air pressure creates a visible bulge. A lump or bulge usually indicates the tyre has been damaged internally.
If you notice a lump, bulge or cut then the tyre will more than likely need to be replaced or repaired immediately. You may also notice cuts, rips and tears to the tyre as a result of ‘kerbing’ or pot hole damage. If you notice any of these then you should have the tyre checked immediately.
Any cut deep enough to reach internal structure renders tyres unsafe and in need of replacement.
