Lift process for removing all 4 tires

If you need to take all of them at once, jack up each axle, take the wheel off then let it down on blocks high enough to get a jack back under it to jack it back up when you get the tires remounted.

Jack up one tire with a bottle jack. Jack it just enough to take the one tire off. Put the spare on that axle. Let the jack down and jack up the tire next to it. Take that tire off and leave the jack under that axle. Take the two tires to the tire place and have them put the new tires on. This process will keep one tire on the ground and allow little stress to any components. Take the two new tires and reverse the process. Do the other side the same way. It takes a little while but is a safe way to do the process.

By far the safest and most stable way to do it.

Takes time & planning but easy to do.

While still on truck jack & block at the frame aft of the rear wheels. Remove the truck or leave it if you don't need it to transport the wheels. The landing leg motors will protest some at the added weight lifting fwd of the blocks so helping with a bottle jack at the fwd frame might be necessary.

Better to transfer trailer weight onto blocks than trust bottle jacks to hold it, especially if the jacks are lifting near their limits.

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.

Stabilizers are not jacks. Think you would crush them. It would be better to use two bottle jacks under each spring perch on one side and take off two wheels at a time.
