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.Tyre Safety Guide
