For what reason do the front tyres of semi trucks typically have spikes attached to them?

When towing huge loads for extended periods of time, semi trucks and other large commercial vehicles benefit from increased traction.

Because of this, many of them have what are called "traction treads" on the outer edges of the front tyres.

Tires with such treads include protruding spikes, typically composed of rubber or a particular type of metal,   

that increase their traction on wet or icy roads.

Spikes can be useful because they can help keep a truck from swaying in strong winds, which is a common occurrence.

It is even possible to customise the side treads of a vehicle to meet the needs of a certain load size and design requirements.

Putting spikes on the tyres of semi trucks is a good way to ensure the safety of the drivers on long trips.
