How To Fit And Remove Difficult E Bike Tyres


– Now I’m sure all very
familiar with the situation when a tire simply does
not want to play ball. So today we’re gonna look at how to deal with those stubborn tires. (rapid electronic sounds) Now it feels like for my
sins, I’ve been called in to tell you just how to
deal with this situation. It actually feels like I’m on detention. And you know what? That probably is how it feels like when you’ve got a tire, and you’ve got a cold day, you’ve got cold hands, and you’ve got a cold environment and you’re trying to get that tire on. It simply is not happening. But what are the different scenarios which we encounter when a
tire will not go onto a rim? Well, it could be that we’ve got a new rim or we’re fitting an old tire. You maybe might have a new
tire fitting on an old rim. Or maybe it simply is that
you’ve got a resistant tire rim and it will not go on. (swoosh) Now there are certain
tire and rim combinations that are not happy together. They won’t pair up at all. But there’s also some very simple things to look at before that. Maybe, just maybe, you’re trying to fit a 26-inch or a 27-inch sized tire onto a 29-inch rim. Obviously, that will not work. But believe me, I’ve done
that myself several times. So check out you’ve got
your tire sizes right first before you start. (electronic music) Right, so, how to deal with a
particularly difficult tire. Now before we start, I
want to point out that sometimes you might have new tires which have been stored
with a kink in them. Now, that might actually
affect how the tire is mounted. You might also be storing your tires in a really cold environment. I believe that has an
impact on it as well, as I feel that hotter, you know, hotter, more pliable tires
are far more easier to mount than those that are cold. (swoosh) So today we’re gonna
focus on downhill tires because they tend to be heavier casing, probably from one kilo
upwards to 1.5 kilos. Sometimes they’re folding and sometimes they are wire bead. This particular one here is a folding one. It’s nice and warm because
it’s super hot in this studio. Okay, first of all, what are
the tools that you need to use when mounting that difficult tire, or should I say attempting
to mount that difficult tire? Well, tire levers. The only thing you need. Either got plastic ones or
plastic-coated metal ones. Now, you should not really
use these with brute force and certainly not on carbon rims. Now, I’ve got my wheel
and I’ve got my tire. In this instance, I’ve got a
DT Swiss 35-mill width rim, as you can see the profile there. Now it’s worth mentioning that
you can actually get tires which are rim width-specific, particularly when you got
2.5 or 2.8-inch width tires. Okay, what I’ve got here today is a Maxxis 2.4 by 2.75 Minion DHR II. So the first thing to do is get your tire. Now, don’t forget, the
tires are directional. Also, wheels are directional
as well, so make sure… I always try to get the drive
side on the right-hand side when I’m putting my tire on. So, there is drive side right-hand side, tire directional, which is the knobs in the right way. So, where are we? Where’s the little arrow? There’s your arrow. Rotation. So, rotation going
forwards in this instance. Cassette on my right-hand side, tire on my right. So what I’m gonna try
first of all is to get, what I’m trying to do is get the tire into the central part of this rim here. So it gives you as much room
to maneuver as possible. So, on she goes. You can do all this, you should not need to have any tire levers
when you’re doing this. Oh, boy. Now, this is actually quite physical. (electronic music) Right, so I’ve had a
one-minute arm wrestle to get 90% of the first
part of the tire on. However, as you can see,
it’s only gone so far. I’ve got about, I don’t know, what’s that? 200 mill? 200 mill there. At this point, it’s time
to reach for the levers. Now, I can actually a metal
lever in this situation. As I said, it’s definitely
a preference of mine. And I’ll start on the left-hand side. Be careful not to scratch
the rim on your bike. Lever over, and then bit by bit, inch at a time, 25 mill at a time… (lever scraping) On she goes. Finish off with your hands. So… (tire squeaking) As you can see, what
we’re trying to do now is get that bead. Now, when I say bead, it means
the outside edge of the tire which has got a wire insert in there. Get that in all the way. So now, obviously you’re gonna question am I going tubed or tubeless for today? We are going tubeless. As you can see, the valve
is already in place there. And if it is tubeless, you start at the valved end of the tire. So, you simply start
working round like this. Look how easy this is. Absolutely effortless. All right, and this is gonna be one go. There you go, mostly
around, so you can see. I reckon around 75%. As you can see, the valve
is the opposite side to where the last part of the tire needs to be mounted onto the rim. Now, this is where things
normally get difficult. Particularly when it’s really cold, your hands are cold, you might be in the middle of nowhere. This is where tempers start to fray. Now, you can actually get
really angry with the tire and try to really
manhandle it onto the rim, (grunts) but it’s not happening. Okay, so we have got
to that critical point where the tire is 90% on. It doesn’t seem to
wanna go on any further. At this point, you need to
make sure that all that tire is actually in the middle of the rim so it gives you maximum amount of diameter of the tire as possible. So, make sure you put it on like that. (tire squeaking) Work your way round. At this point, it’s a case of working from one side… (exhales) to the other. Now, I’ve had a great tip off Pete, my colleague. And he says you can
actually wedge your tire up against a rock or wall. And you got that last 10%. Get your tire lever and then… I’m out of breath already. (thud) Boom, and I think when
you get to that part, (clicking) it should come on– Boom! Look at that. Easy. (electronic music) Okay, now it’s time to take the tire off. Now, you might even be in your garage in the freezing cold northern hemisphere. Or in fact, you might be sat
in the garden in Arizona. It makes no difference. The first thing you need to do, there’s a system with this, is make sure the tire is located into the center of the rim, which is quite easy. Just like this. Obviously make sure the
tire is completely deflated before you do any of this. It gives you as much room
to maneuver as possible. Now remember, I’ve got a 35-mill rim here and a 2.4-inch tire,
a downhill-cased tire. So they’re normally a
little bit more difficult than skinny rims, say 28-mill
rims with a 2.25 tire. Now, when I take a tire off, I always make sure that the valve end is the opposite side to
where I start taking it off. So what you’re trying to do here is get as much space between the bead– as I mentioned, the bead is the wire outer edge of the tire– as possible. So, I’d actually spend a second or two working some space into that top end… (tire squeaking) We’re gonna start taking it off. So, if you can get like five mill there, it’s gonna help you get
that lever in there. So, I’ve got my lever, plastic
lever in this instance. Get it in there. See, that’s pretty tough. So, got one over. There’s a lot of tire levers
you can have a clip part which allows you to
fix out to your spokes. So you set the tire lever,
that one’s in place. (exhales) In she goes, and over it goes. It really is as easy as that. There you go. So once you’ve done that, little bit of brute force. And what I tend to do
is because it’s plastic, it’s not gonna damage the rim, insert that back in and
push it away from you. (clattering) Towards you. And off she comes. So obviously, there’s
many reasons why you might wanna take the tire off the rim. You might wanna put a
new compound tire in. You might wanna put a new pattern tire on, but ultimately, it needs to come off, so there’s various methods
of taking the tire off if it’s particularly difficult. Some people do it from the outer side, but some people do it from the inner side. So what you’re trying to do
is get hold of that tire. There, can you see that? (electronic music) And then pull it. Oof, just over like that. So you got the tire there, and then it’s just a simple
case of pushing that off. (clattering) Say you got one difficult tire, not in this instant, put on and take it off again. Remember, tools are a critical part of any mountain biker’s arsenal. Now, these Park Tools ones, there are plastic ones and metal ones. Do not use screwdrivers, and definitely do not use
your family’s best silverware, best spoons to take your tires on and off. And I love tires, I love them so much. And I think on an e-mountain bike they’re more important than ever. They give you that grip for doing climbs or if you’ve got a low-profile one, they enable you to get more
range out of your battery. So, yeah. If you wanna see more of our tires, there’s a video I’ve
done, just down by here and it’s pretty in-depth, so bear with it. Let us know your thoughts about this video about fitting tires. If you have any comments,
