Lift process for removing all 4 tires
I want to buy 4 new tires for 5er. Want to remove all four tires/wheels, take them and the new tires to a mounting shop. I have hydraulic front landing gear and electric stabilizer jack system in rear...

You can not possibly put 12,000 pounds on the rear jacks, unless you somehow managed to find a way to place the rear jacks midway under a 12,000 pound trailer and balanced all the weight on them.
The front jacks have about 5,000 pounds on them (more than the pin weight for sure, and probably about 20 - 25% more than the pin weight of your trailer. By transferring weight to just the rear jacks and front jacks, you will apply more weight to the front jacks, as the tires leave the ground.
You will be much better off by not putting that much weight on the rear jacks. Instead get some scissor jacks (like used in a car or pickup) and jack up each axle end one at a time, support with a jack stand or some 4X6 on their sides.
You can use the rear jacks to 'stabilize' and remove some weight from the trailer axles. Also you will be raising the back of the trailer as you put each axle on a jackstand. Remember to lower the rear stabilizer as you remove the jackstands, or they will end up with to much weight on them.
Some tire shops will charge extra to install tires you did not purchase there, some will not install tires you bring in at all. Some will install just about anything their machine can handle. Used tire shops are more prone to install anything you bring in, and at a lower price.
I would rather go through the effort to drag the trailer down there, and let them remove the rims and install the new tires. If you have one or two bad tires, then I would make the effort to jack up one side of the trailer at a time, and replace only two tires at a time, unless you are exceptionally far from the tire shop (say more than a 20 mile drive each way).
Good luck,
Fred.
