I had heard the same thing, so I did as some others had done and put a solid 2x4 across the gate under the rear tire. This is suppose to spread the load out over a wider area than just the foot print of the tire. It must work as I went round trip 1100+ miles with no problems. Have also seen some guys will run a c-channel front to back wide enough for the tires to sit in to take some of the load off.
