Bike Tires Vs A Bed Of Nails // Tubeless Tire Torture Test – Part 1

Bike Tires Vs A Bed Of Nails // Tubeless Tire Torture Test – Part 1


I’m not going to lie. I’m super curious how this is going to go. I don’t know about you guys, but for me, life
can just get well crazy. Juggling work and play can be hard and I always
end up feeling like I have way too much to do and no time to do it. It’s times like that when I need to just get
away and for me that means riding my bike. Whether I’m going to a bike trail, or just
riding around my neighborhood, biking can take all my worries away. It’s at times like this where I get to clear
my head and just think. So the other day I’m riding around my neighborhood
and I started to realize something. Think about the bikes we ride all the time. Look at my hardtail for example. It may look simple with just a front fork
– but actually, there’s a bunch of complex things working together for a great experience. There’s the hydraulic brakes with multiple
pistons, the air sprung fork that’s adjustable for your weight. And even the simplest things like a seat post,
that keep on ticking now matter what happens to them. But the one thing I was thinking about that
takes the most beating out of anything else is probably the simpliest – and that is our
tires. Then I got to thinking about my specific tires. They’re by a brand called Kenda and they’re
called the Havoks, which came stoke on my entry level hardtail. They’re plus size 27.5 tires and traditional
in the sense that they run tubes. Now the rims that came on this bike were tubeless
ready, so I thought, you know what, why not set the tires up as tubeless to see what would
happen. For those of you who don’t know, that just
means putting tire sealant inside of the tire – that plugs up any holes or leaks the tire
may have in place of a tube. The biggest draw backs to doing this on non-tubeless
ready tires is they have thinner sidewalls and will leak fluid through them over time. Oh yeah, and the small fact that you’re running
tires in a way they weren’t meant to be designed and aren’t guaranteed anything as an outcome. But I’ve actually run these for the last several
months and never had a single problem. That’s where this video comes into play. Enter a few of my friends – “say hello to
my little friend” – a piece of spare wood I had laying around, a good old hammer, and
a box of nails. Now going over one nail in a piece of wood
is not that big of a deal because the sealant in the tire seals it up and the tire really
isn’t go through to much stress. But, how much torture can these type of tires
really take. And for that matter, any tires. To answer that question, I decided to take
this piece of wood, and start by putting 15 nails in it. So that I can really see what these tires
are able to do… Alright, so we’re all setup, 15 nails in this
board and I’m ready to do a real torture test on these tires. Now, I’m going to have to keep them inflated
to about 30 PSI which is pretty rock hard for plus size tires, but that will allow the
nails to really grab in. Now the distance of the board is only about
half of that diameter of the tire. So if I were to have another one, one full
pass would be one full time around the tire. So with the one I have, I’m curious what you
guys think. How many times over this board are both me
tires going to get before one of them totally craps out? I’m going to say I can make it 10 times, or
5 full times around the tire, but I think I might actually be able to make it more. There’s only one way to find out. Let’s see. Round one. Alright round one went really well. I could hear the air coming out and I could
quickly hear the sealant closing them up and I’m going to do a couple more passes and I’ll
show you you can see every single dot where a nail went in. But we got to keep going. That was just round 1, there’s a lot more
passes to go through. Round 2. Round 3. Round 4. Those holes took a lot longer to seal. I think the less air pressure the harder it
is to get that sealant where it needs to go. I’m going to show you guys a little profile
of the tire so you can see what they look like after 4 rounds. You can see all the sealant from every time
it’s gone over a nail and it’s doing a really good job. Man, I am impressed. I’m most worried about some of these side
holes because I know the more I do it the more I’m going to get closer to this side. So, we’ll keep trying. Alright I’m starting to have to slow down
to get the sealant in the leaks. But I can’t believe it, it’s still working. I think the front tire is getting a bulk of
it because all my weight over the front tire. So, time to focus a little more on the rear
tire. I don’t know if you can see this but there’s
pools of sealant around all of these main nails that I keep hitting over and over again. Alright, so after 10 attempts I still have
26 PSI in the front wheel and I know the back wheel probably has the same if not a little
more. And I’m not going to lie. 10 passes I’m impressed, I’m amazed, because
remember these aren’t tubeless ready tires. But I’m also a little board. I mean I could do this all day and just go
over it 50 times and the tires still work. But that’s not really what I want to do. I want to torture test these things. So I have an idea. So I upped the ante and put in 30 nails in
this board. But is more nails really going to make that
big of a difference? And I think the answer is no. So what I’m going to do is I’m going to bunny
hope directly on to this board. And try to completely wreck these tires while
trying not to wreck the rim tape on my rims. I’m not going to lie, I’m super curious how
this is going to go. Oh my goodness. Alright I have gone doing 10 normal passes,
probably 10 or more ridiculous passes and these tires are still inflated from the first
time I filled them up. And they’re probably down to about, I don’t
know, 15 to 20 PSI where I would normally ride them. And what I found out from messing around on
here is the slower you go and the more you mess with your tires while they’re on the
board, the more the nails really effect the tire. So now I’m going to end off this experiment
by going painfully slow and turning my wheels as much as I can so that the nails can really
mess with the tire. Let’s see how this goes. Nice and slow. Alright so I just spent the last half hour
going over this board 30/40 times going super fast, pretty fast, I jumped onto the board
with 30 nails in it, I went as slow as I possible could and I haven’t had to fill up the tires
once. Now, I’m going to be honest with you guys
I did this experiment because I bought a new pair of 27.5 plus tires for my tokul I’m super
stoked about. But I’m so impressed I decided this is just
going to be part 1 of this video. And here’s what I mean. I’m going to keep these tires on and I’m so
confident in them I’m going to go trail riding with them. But I need your help. I’m going to do part 2 of this torture test
and I need to hear what else do you guys think I should do. Now obviously if I slash the sidewall or if
I take a knife to it, they’re not going to be tubeless anymore. But here’s what I’m thinking. Is there anything I can take with me on the
trail to really put these tires to the test and even if things go terribly wrong put myself
in a really crappy situation? If you liked this video, hit the like button,
but more importantly down below in the comments let me know what I should do to really put
these tires to the test. And last but not least, click that subscribe
button over in the corner that way when I post my part 2 and, who knows, maybe even
3 we can see. But for now, don’t watch me too much more. Go outside and go ride your bike. And hopefully you have it set up tubeless
so no matter what happens you can ride it every single day. 3 days later, tires still inflated to 25 PSI. Help me out guys.
