Jacking /Support tandem Axle trailer?
Is this the best way to lift my trailer and support for tire /brakes etc ? I think this is best way to distribute the load?

With torflex axles like shown here this is the best way.
General rule of thumb is to try and lift in the same way the trailer is supported when being towed down the road.
Regular axles are lifted directly under the spring. Torflex axles need to be lifted by frame as close to center of load as possible.

I use one of these and do one wheel at a time, but I do like your way. I'm getting ready to replace the brakes and may try it.
Thanks for the post and pic!

Think about it; trailer aid:
You are putting the weight of two tires on one. Even for short periods of time the single tire is over loaded!

I'm interested in hearing from someone with tire engineering experience. It's my understanding that problems resulting from an overloaded tire are primarily caused by the heat generated while running overloaded. Not when stationary, especially for relatively short periods of time.

A tire will hold far more static load than what it will carry while running down the road and subjected to heat generated by flex under load.
There is a test referred to in the tire industry as the "V-1 Test" where a round pin is pressed into the tire. Amount of pressure and deformation that must occur without damage would shock most people.
Running a tire up on a trailer aid doesn't even come close.

JCR if thats your trailer, changing tires are the least of your problems. Most of those axles have been recalled. I would swap to spring axles ASAP. Its an easy conversion and not even expensive.

Tell us more about "most of those" torsion axles being recalled...

Like I posted in another thread. I had a 48 foot trailer with them. Terrible experience. The facts are that torsion axles are not meant for tandem or triple axle trailers. They were never designed as such. It helps if you actually understand how torsion axles work. I dont know why they are still in use on some RV's.
