What depth are tyre wear indicators?
The easiest way to check your tyre tread’s legal is to look out for tread wear indicators. These are usually small bars, about 5mm wide, built into the base of the tyre’s main grooves.

Why is my tire wearing on the outside edge?
Front tires wearing on the outside edge is usually a result of aging coil springs. As they lose height, so does the vehicle, causing the whole suspension to misalign, especially in camber. If the leaf springs are also sagging or wearing out, they cause caster misalignment, which may worsen the situation.
