So we have taken this...we still don't have a name for it...we've taken this 4-wheeled
off-road wheelchair...
[Cambry] There have been a lot of suggestions for 'The Cambry.'
[Zack] We can't name it after you.
Anyway, we've taken it 38 miles on a single charge, which is pretty impressive.
The only problem was at the end of the ride we went through a thorn patch and it flattened
3 of the tires...just three.
So I have gone through and I've put a liner between the tire and the tube, and that's
what we're going to show you today.
Do you want to do the snap thing?
[Cambry] [Snap] Lets get... Oh shoot, I messed up!
It's harder than it looks!
[Zack] So the thing with tires is that the rubber on top is pretty thick, but if something
punctures through that rubber and gets to the inner tube, air will slowly leak out.
So there are a couple different ways to keep that from happening.
The first line of defense is with a Tuffy liner.
My buddy Brax has one of those.
And we put that in between the tire and the inner tube.
And then inside of the inner tube we can put something called slime, but we'll deal with
that later.
Alright, let's get that tire off.
So the thing we're doing right now is removing that outer rubber tire from the rim.
Normally we would be able to keep the inner tubes that we had previously, but when Cambry
went over the thorn patch, each tire got punctured like 20 times.
So I feel like the better option for us right now is just to replace that inner tube.
[Braxen] So really the hardest part of getting it off is the initial seat right here.
Once this part's off, it's a lot easier to pull the tube out and get the other side off.
What you gotta do is put a little pressure on it and it's off.
[Zack] Before we put the Tuffy liner or the inner tube underneath this tire, we're going
to take...cuz obviously she ran over a bunch of thorns and they're still poking through
here...little niblets of them.
So I'm going to take my finger and just kind of run it along the underside and make sure
there's nothing sharp still poking down into the tube.
[Braxen] Okay, and then what we're going to do is we're going to take the Tuffy liner,
put it in here.
If anything punctures it, it's going to hit the Tuffy lining first before it actually
goes in and hits the tube.
The Tuffy liners, they come in all different sizes.
This is a 26 by 4.
But you can get them for really any standard sized tire.
Putting the liner in.
It just slides in and then it's going to wrap around the entire tire.
[Zack] So the Tuffy liner doesn't stay in place all by itself, it needs the tube inside
the tire to kind of pin it between the sidewall.
And then I just kind of hold it up like this and make sure, feeling the liner on either
side all the way around, making sure it's centered right on the treads.
So with fat tires, they're a little bit harder, yet also a little bit easier to get them on
the rim.
I've found that it's easiest to lift up the rim, tuck the tire underneath.
Sometimes you can use like 2 screwdrivers for this to keep it in place.
And I'll just work my way around.
Perfect.
Okay, so now we have the brand new inner tube in, the liner between the tire and the tube
itself, and now we're going to put slime inside of the tire, which is pretty cool.
[Cambry] I'm taking the valve stem out.
There we go.
Okay, the valve stem – it keeps the air in the tire.
We're taking it out to put some slime in.
[Zack] Slime is interesting because it stays liquid all the time and it's just going to
be a puddle of slime inside your tire.
And if your tire ever does get punctured, the slime fills the little puncture hole and
plugs it so the air doesn't escape.
The valve stem is back in place.
So the slime is inside the inner tube right now, and we're just gonna kind of like coat
the inside of the tube with it.
And now we can fill the tire up with air and put it back on the bike.
We're set.
Once everything's back into place, drive it like, I don't know, like quarter of a mile
and make sure all the slime's good and coated.
And so that is how you protect your tires against being flat when your driver likes
to go through patches thorns.
Do you feel safe that your tires are going to be intact now?
[Cambry] Yeah, I've got dual protection: liner and slime.
[Zack] A liner and slime.
Huge thanks to Brax for helping me out with this project.
If you haven't seen his channel yet I'll leave it linked right here, and thanks a ton for
watching.
I'll see you around.
[Braxen] Peace.
