The concept of long haul puts a lot of pressure on your tires. You will need extremely durable tires to be able to handle the massive loads over very long distances and keep doing that day in and day out. The machines are not purchased to stand still so they are in constant motion as much of the 365 days per year if possible.
You will need to invest in special haul tires regardless if you choose bus tires or heavy truck tires. Durability and low wear is key to ensure a smooth trouble free operation around the year, with minimum downtime and maintenance stops.
