I had a most peculiar and frightening experience this weekend that I would
like anyone to comment on that may have had this experience, or heard of it.
I was returning from a backcountry trip on the freeway; speeds were about
75mph. After about 25-30 miles I felt the bike suddenly lurch and heard
this sound that I thought sounded like the engine losing spark for a few
seconds. The bike continued seemingly normal. After about another 40
miles the bike lurched really hard and again I heard that sound. I was in
heavy traffic and it was not safe to stop and again the bike continued
seemingly normal. When I got to my exit and started to slow down I noticed
a pronounced bump in the back wheel as if there was a big lump in the tire.
When I finally came to a stop and got off the bike I could hardly believe my
eyes and a cold chill ran through me! About a foot to foot and a half of
the tread on the rear tire was gone! Yes I mean gone; all that was left was
the smooth black rubber with cord showing through in places. The tread had
peeled off like a skin. I knew then that the sound I heard was the tread
coming off and hitting the frame. The tire was a 2 year old IRC GP-1 that
had lots of tread on it. Does anyone know how/why this happened.

I can't really talk about the cause, but you sure nuff chunked a tire. If you want to see what it looked like when racer Steve Rapp did that in the race at Brainerd, take a look at: http://www.amasuperbike.com/000731a.htm That's a link to the article; there are links to photos at the bottom of the story. And here is a link to the followup article: http://www.amasuperbike.com/000803e.htm Anyway, glad you're ok. That doesn't sound like fun. Ralph Ralph E.

Come on now, that's not fair. When was the last time you heard a Kenda or a Maxxis or whatever else come apart like that? I certainly haven't on this list, and they are priced below the IRC.

There are 2 possible answers. 1)someone allready mentioned - poor quality
control or manufacturing. 2) Low tire (air) pressure. A tire with low
pressure will over heat and seperate the tread from the cord rapings. I have
seen this on cars alot. It doesn't have to be a recap like the truck tire
treads that you see laying in the road.
A kinda funny story - A friend of mine who worked in a gas/service station
that installed new tires would always talk about how dumb some people are
for driving on a tire that was low on air. At least once a week he would
have a tire in his shop that had seperated do to low pressure causing it to
over heat. A steel belted tire look real nasty and you should see what the
fender of the cars look like. Anyway, one day he was going on a weekend
fishing/camping trip with his girlfriend
and stopped at my work to pick up something. I noticed his front tire (big
4x4 35" x 12") was low and told him he should fill it up so it doesn't
seperate like all those other tire stories he told me about. He said it
would be OK. On Monday I saw his truck with new tires on front and one of
the fenders looked like it was beat with a ballpeen hammer from the inside
out. I asked him what happened did his tire sepperate. All he said was
shut-up. His girlfriend told me he didn't fill the tire with air and it
sepperated on him. Now when he talks about dumb people he can add himself to
the list.

they have other problems, namely traction, or lack thereof. the expression "rim protectors" was invented for cheap tires such as these.>>>The tire was a 2 year old IRC GP-1 that had lots of tread on it. >>>Does anyone know how/why this happened. >> >>IRCs are relatively cheap tires. you get what you pay for. > >Come on now, that's not fair.

do what you wish, i'll stick with name-brand tires. call me olde-fashioned, call me conservative, but your tires are the only thing standing between you & a serious crash; thus, i prefer mine to be top-quality. dunlop, metzeler, michelin (for racing), & bridgestone. gears, ye wilde ryder -- wallace@... 99 zx-9r "blue bayou" 98 vtr-1000f "stormy" zwallace@... 86 cr-250 "dirt devil" 00 sv-650 "zipper" "& you were using your friends as a berm." -- RP 83 v65 magna "nasty" FoJ#002...AMA#456832...JHLO#002...COP#000...CCS#SW969...Support the RKBA>I certainly haven't on this list, and they are priced below the IRC.

ride reports are interesting, but i've not been contributing much in that
regard despite lots of time in the saddle so i thought i'd offer up a short
but entertaining one for a laugh. it's funny now anyway...
my friends and i were tearing around our usual riding area, included in
which is a pretty steep and fun climb we call "pork chop hill". sal, a very
funny guy and very good friend, was as usual carting around his 250 lb
carcass on his 1979XR250 (or maybe XL250S, but that's another story...) and
had just climbed pork chop hill for the umpteenth time. however, this time
he decided to turn around and head back down. this is not our usual path,
but hey there aren't any signs (yet) saying "one way only", so there he
went. i was having a ball on my little kx125, churning through the fun
piece of single track approaching the approach to pork chop. around the
turn i came, peeking up the hill (nobody there... i thought...), and
gunning it for the approach. after the last sticker bush slapped me in the
face, i directed my attention up the hill. HOLY #&$@! i can't describe the
feeling in my stomach as i saw, barreling down the hill straight towards me,
this rather big (he's not fat, he's dense) guy (i think he was wearing the
holographic "psycho eyes" goggles too...) on the rattiest rat dirt bike
you've ever seen (we affectionately call it the armageddon bike). i
instantly stalled the bike and (with the help of daul disk brakes heading
uphill with a <200 lb bike) stopped on a dime. too late for poor sal,
though, as he had basically 1/2 a second to make a decision: hit pete, hit
the bush... hmmm... well, at least bushes give. i had about the same
amount of time for the prefrontal lobe in my brain to formulate the thought
"no, sal, wait, i've stopped", but no time to speak...
suffice it to say that a big guy on a little rat bike careening into a
really large sticker bush (which thankfully did a terrific job at halting
his forward momentum in as gentle a fashion as could be expected) at high
speed and then being expelled out the side unharmed is probably one of the
most spectacular sights one can witness from such a perspective.
sal is working on a new bumper sticker at work. it will say "i bush for
brakes".
