good evening YouTube so this is the original tire that I put on this bike when I built it back in
2012 so it's seven years old and has something like 90 200 miles at least on my bike computer
it's probably more than that fifteen thousand kilometers and so this tire was originally on the
rear of the bike for twenty five hundred miles and then I converted to two blessed and moved it to
the front and so it's got over 6,500 miles on the front probably make out in the camera how crack
the tread is there's these cracks run straight and then there's some that cut across the tread blocks
and this has been cracking like this probably for at least three years and you can probably also
see they're sort of wet spots so less two years roughly I've been noticing a little bit of extra
sealant used so about three or four weeks ago I added some sealant to the tire because I've gone
low and just the other day I was looking and right here it's finally cracked all the way through to
the casing so I think it is time to retire this tire I mean I pumped it up last weekend and it's
still holding air but it's it's letting go along this whole stretch there what I have here this is
the other original tire this one was 2,500 miles on the front like this tire and then when I went
to bliss I put it in the back and it ran about thirty five hundred miles in bath until I got a
puncture I showed you in a video several years ago where I took this tire off and I got a puncher it
was a nail a finish nail went all the way through the tread and came out right on the side of the
side wall where the side wall meets the bead right there and I've been sitting on this tire I haven't
done anything with it but I thought why not give it a try here and this one is same age and it
doesn't have any cracking on it the puncture was down in that groove down there between the fabric
and the sidewall so what I did was I glued several inches of that fabric down just for a little extra
support outside and then on the inside I went and added a patch there why your brushed all
the sealant residue off of there there's not a lot of rubber on the inside of these so you have to be
really careful that you don't go into the casing but I got that patch in there I think that's
pretty good it's a car tyre patched which I think might do better on this thicker rubber because
you're not patching the tube you're patching the tire so I think what I'm gonna do is pull this
tire off I'm gonna put this tire on and then put some sealant in there and see if it holds air okay
you tube got the old tire pulled off of there kind of a mess with all the sealant residue and then
here we got the the rim cleaned up went around with a rag wiped out all the stuck-on sealant
especially along the beads here so just one last check there I think we're looking pretty clean and
they used a rag with some acetone to clean off the bead got the outside edge and then the face there
make sure that's all clean so we get a good seal let's get this mounted and we'll see if it'll air
up yeah being this tire was used already it went on pretty easy didn't have to use any tire irons
that's what I'd like to do is just go around and kind of roll the tire over both directions push
it that direction and then turn it around and go that direction just to get it all centered up in
there okay here we go got the tire hanging here from my hook and big thing you want to watch is
the pressure you don't want to go over 50 psi or even 45 so let's just see what happens here
think I'm quite seated in there yeah okay I think I got it seated in here where I out
of the patch it's a little bit stiffer right down here and I need to hold a little pressure
on there to get it to seal there we go got her to pop yeah see it's still leaking right there
I think that's around the bead I don't have any sealant in here so I'm gonna give them
sealant and we'll shoot it in here okay I got my little bottle of orange seal here that's most of
it let's get the valve core back in there yeah so now I need to put some air in here and then
shake the tire around flap especially over here I need to get some sealant in this area is gonna
be a little stiffer because there's a the patch inside and then I've glued the extra piece of
fabric around the bead okay the trick here when I first put it on there was just bubbles coming out
we've got some leaks around the bead that are seem to be filling up and the other side
had some small leaks but I've pumped it up to about 40 psi and it's probably about 35 now see
we had a pretty good leak along there and then there was one over there and a little bit kind
of that whole half I probably didn't have the bead like perfectly clean I got it as clean as
I could but at some point you just got to stop trying to peel off all the little bits of latex
this is where the leak was right around the valve stem there looks like it's pretty well sealed up
yeah I think I'll let this sit maybe half hour 45 minutes and then I'll probably dump in some
more sealant because I don't hear any sealant sloshing around most of it leaked out trying
to get it to seal up I will probably stick a little more in there and imagine the the old
sealant residue dried-up stuff probably soaked up a lot of the liquid anyway I'm going to let
this sit for a while maybe grab some lunch and then I'll pull the valve core out dump
some more sealant in and pump it back up and just make sure all the little pin holes are
sealed up and I think we can throw it back on the bike and go for a ride later today
