Jacking for a flat tire?

It is quite simple to use a bottle jack under the bottom leaf of the spring pack to lift the wheel. A sizable chunk of lumber might be needed for the jack but not having the right tools when you have to take care of yourself when things go wrong in the middle of nowhere is not an option.

Zero worries about frame damage,axle tube damage,where the jack and handle is(and what's on top of it)or semis rocking you off the little saddle on the jack.

Maybe you're just not thinking hard enough. Lots of triple axles trailers rolling down the road and I don't think your idea will work too well for them. Or do those count as exceptions too?

One can always find exceptions.

I'm just the opposite.
Having split a tread belt a 16.5" load F bias ply tire tire on a flatdeck trailer by ramping the good tire I don't/wont use that method anymore.
I keep it simple and safe by simply jacking one end of the axle from the tube or U bolt. I've jacked more trailers on the road this way than several RV owners.
There are some multi axle leaf spring suspension trailers that a ramp under one tire will not raise the other due mostly to a long equalizer bar setup.
Also a ramp under one tire won't raise a multi axle torsion setup.

Choose the method you like but make a dry run at home.

For those who use bottle jacks, make sure your jack will fit under the spring plate WHEN THE TIRE IS FLAT! Don't ask me how I learned this.

I use the jack that came with my truck.

Read your owners manual. You should place the jack under the frame, not the axle. Using the axle could cause damage and those who recommended using thee axle wont pay for damage to your axle or will the manufacturer pay on the warranty.

I tried that with a 6 ton floor jack, as I don't carry the Jack in the truck when we camp,and the bottom of the frame is 2 feet from the ground,plus the side of trailer is almost off the ground . I will stick to a bottle jack under the u bolts

Just delt with this last week. I used the scissor jack that came with my Expedition placed under the axle tube between the u-bolts. That way I just had to lift that one wheel, and only an inch or so. Took me 20 minutes start to finish.

Every trailer is different. My TT is a spring over axle, and the frame is 16" off the ground. In order to jack from the frame, I would have to first reach it, then unload the suspension, then lift the tire off the ground. I don't think so. The axle tube is plenty strong enough where the u bolts are to take the weight off the one tire.

Just wondering Wandering1, have you ever changed a tire on the side of the road? Do you actually realize how much work it would be to jack the frame up, and how far you'd have to jack it to get the tire off the ground? I can't imagine it with my triple axle toyhauler.

No way would I ever be able to jack on the frame, and I would never feel comfortable jacking in only one spot on the frame.

This is my feeling also on jacking the frame. I guess I need to redesign my home made ramp and make it shorter. I made it long to have a more gentle grade.I bought one of the plastic drive up ramps and the trailer weight smashed it. Thanks everyone for your input.
