tire changing jack

No jack. Homemade wooden ramp. 2x6 board. Loosen lugs. Run good tire up ramp. Block TT’s other wheels. Change tire.

If you have a tandem axle trailer check out something like this:
Trailer Aid

6 ton bottle jack. I won't use those trailer aids as they put all the weight of one side on one axle. A bottle jack only lifts the flat tire an inch or so and the other tire stays on the ground so that side of the trailer is supported by both axles.
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.

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.

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

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

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

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.

Good points, valhalla.

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