I had to use the truck to pull a very heavy trailer loaded with drywall. The guys that were loading the trailer had to use one forklift to set one end of the stack on the back end of the trailer while the second forklift pushed it from the rear to slide the stack on the trailer. Usually this presents somewhat of a problem as the forklift will tend to push the truck and trailer forward quite a bit as the load is being pushed on the trailer. I have noticed that the traction with these tires was pretty good and they proved themselves while being loaded this time. As I held the brakes on the truck while the load was being pushed I noticed that the truck didn't even budge. Hats off to these great tires!
