Tyre Safety Guide
This is the kind of damage that we often see here at Pellon Tyres. Consequently, some of the “eggs” that appear on the sidewall of the tyre are very minor. Never the less, they do worry people. Drivers are always calling in to see us with small bubbles on the side of their tyre.
Most of the damage is caused by the tyre catching the curbside. This often happens when manoeuvring the car. The car may catch the kerb and due to the motor vehicle weight and stresses, the tyre breaks a sidewall cord. Sidewall cords are unyielding and do a lot of work, taking much of the tyres weight.
When the cord breaks, then it allows the rubber surrounding it to form a small lump. This is the air pressure pushing the rubber out, where the cord has broken. The general rule is that the more sidewall cords that break, then the bigger the bulge. Some so-called “eggs” can be huge.
So, I would recommend that is you notice a bump or any other sidewall damage. Then you should get some expert advice and call into your local independent tyre dealer for a second opinion. Whatever you do do not try to prick the bulge. The damage is more like an external “Hernia” and cannot be repaired. Neither should you be unduly worried. If you spot a bulge on your tyre on say, that your holidays. Then put your spare on or drive home carefully. Of course, it is very rare for the tyre to disintegrate completely?.
In the early days of radial tyres. Tyre manufacturers would have; that would cause a similar effect to the side-wall.As a result, the industry now manufactures tyres in immaculate and hygienic factories. This has now eliminated the fault.
