flat tire

[jim22]

I have a TT, 26 foot long, weight around 4800 pounds. The jack i have is 1.25 ton is that big enough to jack up the trailer and also am i going to damage anything under the trailer. I take it the frame is around the edges.

Be careful where you put the jack. Keep it on the axle that needs to be lifted and place it as close to the wheel as possible. Do not lift at any of the trailer frame points.
It sounds like the jack you have will be at or near it's limits for your TT weight. A 2 ton or higher weight rated jack would be better.

" Keep it on the axle that needs to be lifted and place it as close to the wheel as possible."

Please don't place a jack on the axle itself, use the u-bolt mounting plate or the frame.

A 2500lb jack will probably work--if the TT wt is 4800lbs, less tongue weight each wheel only carries about 1000-1400 lbs. Now if the 4800 is the factory 'dry' weight, you might be near the capacity of the jack.

Bottle jacks are very cheap for a lot of lifting capacity--might consider a 2-4 ton bottle jack with the adjustable screw top.

I have never done this myself, but I have heard if you have tandem axle, just run the tire that is not flat up on boards and it will lift the flat enough to change it.

That will work on most suspensions, if you don't mind putting the weight of the flat on the other tire.

Has anyone tried this with a Wide-stance axle setup like we have on our Sunset Trails trailer?

What is different about the 'wide-stance' axle setup?

[RVhauler]

The lower the tonnage capacity of the hyd jack the harder it is to lift the load. If you find yourself under the TT then the easier it is to work the jack handle, the easier to lift the load. I personally carry a 12 ton jack (I also have a heavier load) but would recommend not less than a five ton. Size/weight of larger jack is not much more than your present jack. As for driving up on boards some rigs will do it and others will not clear the ground enough. Been there and tried it

Wheel treads are 20 inchs apart, wide trax. This driving on blocks will not lift 2nd tire unless you are on very high blocks. suspention is different setup and will not lift like the normal double axles as the spacing of shackles and pivet points are spread farther
