Did you put anything inside your rubber tracks to help with tire slip (Either increase it or decrease it)? Mine have what looks like pieces of UHMW "Flatbar" across the inside. I suspect that they were put there to help the tires slip a little bit to reduce chain windup tension. Even with those I still have to closely watch my tire pressures to help ease the windup tension as much as possible. If I don't do that, tension will build and when the tire finally slips a bit inside the track it can make a hell of a BANG and jolt the whole drivetrain.
