good afternoon YouTube I've got the front tire off my cross bike here this is the rear tire so this
is the tire I patched earlier this summer that had the puncture so I run these tires to bless
their the schwab marathon Mondial tires 700 by 40 see his tire had a puncture in it about
three years ago and at that time the tire was on the back of the bike so I took this one off put
this tire on it was brand new three years ago it now has about four thousand miles on it in light
of trying to prolong the life of these tires I need to move this tire to the front of the bike
because it's starting to get pretty well worn down trails that I ride up here in the summer
get very abrasive on these tires they're kind of a combination a gravel and sand and silt a
really fine powder that builds up on the surface of the trails probably three or four inches deep
and it just grinds away the tread and then you you also slip a lot when you're going uphill
so this tires pretty well ready to go to the front on the front it's not gonna wear very much and
I'll probably get another three or four years out of this so normally I would put a brand new tire
on the back but this tire actually has better tread so I'm thinking I will just swap these
two tires front and rear and I can probably get another year out of this before either the tread
wears out or the rubber starts cracking due to age because next spring this tire will be eight
years old that seems to be about where the rubber starts drying out and cracking so this tire was
on the bike when I first built it in 2012 it was on the front of the bike for 2,500 miles and then
when I converted to bless I moved it to the rear and then it had about another 3,000 miles in back
and then since I patched it this summer it has another 500 miles in the front so this tire has
6,000 miles this one has 4,000 and you can see how the tread wear on this one is much less and that's
partly due to 3,000 and back versus 4,000 but it's also when I first started riding this bike I was
doing more flat riding on the various bike trails down in the valley floor and then when I was doing
the hills I would go up the hill on pavement and then I'd come down the hill on the dirt but the
last three or four years I've been riding more uphill on the dirt and then downhill on the dirt
and going uphill in the this loose sand and gravel mix really chews up the tires oh yeah anyway what
I need to do is let the air out of both of these where you will take this one and this one off and
then flip them around mount them back up add some sealant and see if we can get these to seal up
and then take them out on a ride in the morning okay I got the front tire off and yeah the patch
I put on there is holding up perfectly well so I didn't know how the patch and the glue would
stand up to the ceiling but doesn't look like any real problems and I was pretty well dried out on
the sealant though that's the other thing I was kind of waiting for I wanted to make sure that
I didn't have too much sealant sloshing around inside here so it's pretty well dried up let's
get this valve core out I think I might want to change valve cores they're getting a little bit
sticky yeah this one's the same you get a little bit of buildup in here okay so we're getting the
rear tire off here and I think this tire I've only run orange seal in it it's really amazing
the whole inner surface of the tire was basically just covered with a layer of rubber here look at
that and it's just pulled off totally clean just a little bit left you know I'm trying to get the
bead cleaned off but I mean the rubber is just just like brand-new inside and the whole inside
of the tire was covered like that the front tire wasn't quite the same because it had some of the
dried Stan's sealant in it yes that's about three years worth of orange seal residue out
of the back tire a little bit out of the front but I'd only run one measure of orange seal in
the front tire and it was all cleaned out this summer but that's out of the back tires there's
a fistful of that stuff and it cleans up really well just take your rag and kind of pinch it on
each side of the bead and then just pull it along from the rubber just fall off of there this one
doesn't have any excessive buildup anywhere it doesn't look like there were any places that
it was leaking at all yeah I think we're ready to mount this one up and I just run the same rag over
the bead remove most of the residue and go around you just have to catch your thumbnail here in the
corners and make sure you get that bead seat all cleared out these are directional treads I think
that's right we've got the these or the points going forward and the discs on that side yeah
so there we've got got one side over start here at the valve stem once these have been mounted
they usually go on pretty easy get it knocked down around the rest of the way yeah there we
go I think we're there did that last bit in there no tools required okay let's get some sealing in
this this thing popped right on and I didn't hear any air leaking out even with no sealant in it it
was holding four TPS alright this is the front tire here I just pumped this one up after adding
the sealant got a little bit of leaking and this is the front tire moved to the back and it it was
leaking pretty good when I first pumped it up but in about half an hour it's pretty well set
up not much on that side either got a little bit of sidewall leaking here since this one is the one
I stripped all the rubber out of the inside of it it's probably lost all its sealing but yeah
there's that sorry let's he sit overnight and this should be good to go in the morning that's another
tubeless lesson I've learned that if you take one of these off lean it out while it's fresh don't
let it dry is for example here's the old cracked tire that I took off and this one I didn't clean
up but you can see you know once that rubber dries it just tears into little pieces and it's
very time consuming to clean up because it's it's dry rubber at that point and it just pulls apart
so you have thousands of little pieces to get off versus if it's fresh you take off that much at a
time this one has to get tossed out and probably next year that one will join it finally be able
to put a new tire on the back and then I won't have to touch the front tire now for maybe four
years just leave this one up front add a little sealant every once in a while and we should be
good to go so yeah show you what these look like in the morning and we'll see if they've sealed up
