Hi,
Heavy vehicles have broad tyres because broad tyres have large area of contact and less pressure on the ground. Because of this, heavy vehicles (like tractor) can move even on soft roads and fields without sinking.

Explanation:
Pressure exerted by an object is inversely proportional to its surface area. So, tractors have broader tires so that the pressure exerted by them on soft soil (typical for farmlands) is comparatively less and they do not sink in as they are very heavy indeed.
