tire changing jack

[jotityra]

What kind of jack do you carry with you in case of a flat tire on your trailer? I'm looking at a bottle jack that has a jack stand in one assembly. like this: Alltrade Tools 620470 Unijack Hydraulic Jackstand, 2-Ton


I used to take small floor jacks but they are too old so I'm looking to get something just for the camper.

You have the tandom axel, get the trailor aid or just block up one wheel untill the other gets off the ground. . Your not moving so not really stressing the other side. If it was a problem they wouldn't make them. Carry a bottle jack as a back up.

“do you think that a 2 ton jack would be enough?”

This is not the time to save $15 on a 2 ton jack vs. an eight ton. “Just getting by” gets old real fast.

I still use my old 1978 Truckers special 12t hyd bottle jack. It has a 10" X 10" base made for side of the road use. Long jack handle easily slides the jack under the axle tube next to the U bolts. It came with a adapter that cradles the axle tube. Its jacked 1750 lb on up to 11000 lb axles on loaded trailers. I just had it repacked for the 3rd time since '78.
As one poster say just jack one end of the axle just enough to get the spare back on. That way I'm not lifting the whole side of the trailer.

What ever method you use do a dry run at home especially with those drive on blocks. Lots of members over the years found out they didn't work with their trailers suspension.

I was figuring that the camper weighs 4200 dry, 6000 loaded and if it is still connected to the truck, and i'm only lifting 1 wheel do you think that a 2 ton jack would be enough?

I carry a bottle jack, but I find that my Ford F350's jack is a lot easier to use because it is raised with a long crank handle that I can operate without being underneath the trailer. (Each trailer tire supports roughly 2,000 lbs. so the F350 jack is not overloaded.)

Heres a tip. When the bottle jack, or whatever you have is too tall to fit under the axle, use your leveling blocks to drive the good tire up onto or even under the flat to raise the axle enough to get your jack in place. Got the T shirt

3 ton bottle jack and a 2x6x6 piece of wood for ground support

Amazon has the same jack you're considering except it has a 3 ton bottle jack.

Good points, valhalla.

I have 5200 lb axles. TT has 7850 lbs on the axles. 1/2 of 7850 is 3925.
1/2 of 5200 is 2600 lbs.
I'd be supporting 3925 lbs with 2600 lbs of axle using a trailer aid.

You do realize, your axles likely see 10,000lb or more when they hit a pothole at 60mph.

Jacking is for practical purposes a static loading situation. The ratings are based on dynamic loading.

That said, we have a 3 ton floor jack and if it's squishy ground, the leveling planks can be put down to support it.

I've successfully tested and used my tow vehicle jack for my trailer. I'm not sure why it wouldn't work for others.

I carry a 6 ton bottle jack. A 2 ton is barely enough for my light weight TT.

[kellem]

I use trailer aid and have every tool ready on hand.....it's like a pit stop when I flat.

[Lwiddis]

Why do you assume I lift the flat tire more than an inch with my ramp? The tire on the ramp bears weight! Way off on this one, goducks.
