Why is a petrol tanker sometimes connected to the ground by means of a wire before petrol is uploaded?

Most likely, this is to discharge any static electricity that the tanker may have accrued during its journey. Such static can be dangerous because it may cause the petrol to ignite; therefore, the wire 'grounds' the tanker (i.e. it allows the electricity to pass harmlessly into the ground) and removes this threat.
