How do you replace all the tires on a 5th wheel?

I went by a local "Tire Shop" the other day and saw a 5th wheel in the parking lot getting at least one new tire. It had a floor jack under the axle about 2' inside the spring mount. I made mental note not to buy trailer tires there

I'm just the opposite.
Having operated a five trailer business on the road for several years those are the shops I looked for just to change a single tire.

I would suggest not pulling one tire onto ramps to take off the other same side tire. This overloads the one tire that now carries all of the weight of that side of the trailer, possibly causing damage. Tires are rated for only so much weight, and trailer tires are usually close to the max already...to virtually double the weight isn't a good idea.

Jack up one side, then the other. Don't use the axle tube for jacking.

The poster who commented about tire dealers jacking incorrectly is dead on. My experience has been that most tire dealers have no idea about jacking a trailer.

I put the spare on and leave one on the jack. Take the two down and replace. Repeat for other pair, done. Yes I jack on the axle U-bolt to lift it one inch.

I also supply my own stems and insist on lug centric balance.

I'm still wondering how you change that 5th wheel?? And just why is it a 5th wheel. Inquiring minds need to know.

I take mine to my local tire dealer and they change them.

When I got ready my son brought over 2 ramps made from crossties. Put them in back of the back tires and backed up. Front two tires off the ground, removed and drove in for replacement. Returned home and mounted them and moved the ramps to the front of the front tires. Pulled up and back two off the ground. Repeated. We checked the wheel bearings and brakes while in the air. This was with the Trail Air suspension and had no problems with ground clearance. Very easy and simple except for the 12mi trip into town. An air wrench helps.

I kept the 2 best tires for emergency use. If I have a mountable spare in the bed of the truck in addition the the regular spare it scares Murphy away. He hates people who are prepared. Realize though this is for a month long trip next month, not our usual less than 200 mi runs. For them I'll take my chances.

1. Don't forget to have the bearings packed. I do it once a year.
2. In calif. you call and drive your trailer to a Les Schwab dealer. Done deal:) I suspect you could call any truck shop.

I use Lynx leveler blocks to build ramps under both tires on one axle. Loosen lug nuts on other axles tires, pull up on ramps, remove two tires (one on each side). Take tires to shop for replacement. Upon return, grease wheel bearings, check brake parts, and then put new tires on TT. I then repeat for second set the following day. Note this requires TWO vehicles, as I leave TV and TT attached to do this.

I do the axle with the best old tire last, as that becomes my new spare.

I jack up one side one axle at a time and use jack stands under the axles while I remove tires and go to the tire shop and have new tires mounted. It takes a couple of trips but it works for me at my lesiure.
