Ray,
I wouldn't recommend using your TM's scissors jack stabilizers or any jacks to elevate the ends of your TM trailer in order to take the weight off the tires. This appears to be false economy because in trying to extend the life of the tires you may be causing damage to your trailer's frame. Engineeringwise, the steel frame of your trailer functions as a beam. Most of the load on it is concentrated near its center and, therefore, the axle and tires are placed closely underneath most of this load. This design relieves the stress on the frame under ordinary static and towing conditions - and allows the framework to endure the additional stresses caused by bumping along on rough roads, or excessive weight that you may have put into the trailer. If you elevate the ends of the trailer with the stabilizers or jacks and raise the tires off the floor, you're now supporting the "beam" only at its ends. The beam or framework then will be subjected to its greatest bending loads, and, may be permanently deformed or fatigued.
The stabilizers are only for "stabilizing" the corners and to reduce the trailer's movement when you walk around inside of it or the wind hits the outer walls. It's probably okay to use the stabilizers temporarily to raise a flat tire off the ground if you don't have a jack to put under the axle. Raising the tires off the ground over a long term, however, might do significant damage to your trailer's framework.
