What do you call those and do they exist?

We carry pieces cut from 2x10's to put under the jacks but they also double for getting us unstuck in sand or loose, wet places (that we should have stayed out of.) You know the drill. Boards under the jacks to lift the tires out of the holes they dug then boards under the tires to get out. One problem with this id that modern lumber is weak and splits. One thing to do is to build up boards out of plywood but that is a pain. FInding older oak boards might work too if they could be found.

Do they make sturdy plastic supports that are long enough to get under 19.5" dualies and support 13 tons over the sand? two feet would probably do it. What would you call them? I have tried to find them but don't know what to call them.

I believe they are called traction tracks or traction mats. No idea on the weight limits for them, but many can be found easily on Amazon via those search terms and you can evaluate from there.

Something that come to mind are “outrigger pads”.
I bought a set from this company and are made of good material.

Take a look at their website, maybe it will help?

They are called recovery tracks. The premium brands are MaxTrax and Treds. But also lots of other ones that are probably all from the same factory in China.
They work really well but be aware that a major recovery can destroy them in the process of getting you out. But at that point, it will be well worth the money.

For what it's worth when stuck at times over the past 30 years: We've used whatever was to hand: cardboard boxes broken down in, or plastic big rough finish sacks from our wood stash even torn tarps to get out of being stuck in sand on the Oregon coast when we thought we were safe and we'd only gone a few feet off the highway, and same again after a heavy rain stuck us in mud. Found wood we used just split with the weight of vehicles whether dually and fiver or the Moho.

If all above failed we waited for someone to give us a bit of a tug = there's some awesome folks in the world still today

Some folks carry a small stack of asphalt roofing shingles.

Saved my own bacon by having boards a few times. Those lego blocks are only good for what they were designed for, & even that is questionable. Boards have many uses finishing up as firewood at the end of their useful life.

There puppies are lightweight, foldable, and very inexpensive. They’ve gotten me out of several slippery situations, and also work well in loose gravel.

Excellent suggestion. Not the first time I learned from a Marine.

[BuggsMcBuggs]

I call 'em Floor mats.

[Kahoona]

Thanks for all of the suggestions. I might just try one of each to see how they hold up.

There are MaxTrax and then there are the chinese versions which might survive your dually once.
