Yeah, good luck with that Bust, since half of the Canadian FJR Forum and a fifth of the American FJR Forum have already seen your moon!As I only managed just over 2K on my tire I' can't say what the sidewalls will look like after 20 30 Thousand.. Mine looked just fine internally but the left outside had a massive bulge from the pothole.. :blink:
Until solid proof comes in regarding this I ain't going to waste another second thinking about it..
Keyrist! I'm still trying to convince folks the moon landings never happened..
Excellent questions, bum.Just a question in furtherance of understanding the rim crack and interior sidewall damage on Doug's CT:
What do the interior sidewalls look like on CTs (or on the same tire Doug was using) that have been replaced when the tread is worn out? I mean, is anyone sure that the interior sidewall condition on Doug's CT was the result of 1 mile to the Ranger Station or 15 miles riding after he began to feel something wrong?
Since a CT isn't designed in anticipation of having the car wheels on which they're expected to be mounted being torqued away from parallel with the road surface as much as happens in a MC application, is there a chance that CT sidewalls (or those of the brand and model Doug was using) might be inadequate to withstand the sidewall fatigue resulting from MC use (such that it might become unsafe before the tread is toast)?
And a secondary question: What role did the condition of those sidewalls play in the resulting wheel crack? It seems that much of the discussion assumes that there was an impact that caused the crack, maybe that such an impact or other cause occurred after the tire was deflated. If so, what was the cause of deflation, and was the deflation instrumental in the wheel sustaining an unprotected impact?
Don't have a dog in this fight -- just interested in the engineering issues.
Resistance is futile.Except that.... it is a data point.Seems a little whimsical to call that a data point.
The crack rim actually happened.... it was witnessed... and verified.... and photographed.
To be sure, it's not a data point the kool-aid drinkers want to believe.
But the *fact* of the matter is... thousands of FJR wheels have turned millions of miles, and nobody has ever seen or heard of a single occurrence of a cracked rim. Ever.
And the *fact* of the matter is..... after 40,000 miles of CT use, a Darksider has a cracked rim... which was unheard of before now.
I realize the kool-aid drinkers desperately want this CT mis-application to be a success, and take all manner of umbrage when presented with undesired arguments, and want to blame everything under the sun for the crack... except the tire.
But I am reasonably sure that most forum members - who are not clouded by the kool-aid - can draw a reasonable conclusion here. Just as I am reasonable sure all the Darksiders will continue to allege this is a perfectly safe and good idea. At least until the next cracked rim.
No, my friend, I have not. I did do that other little multi-day rally and rode as many or more miles as many of the IBR riders have. FWIW, I rode as many miles over that 14 day period that covered getting to the rally, riding the rally and riding home as you did for your outstanding 13th place, Gold Medal finish in the '09 IBR..... then put another 9k on that front tire and the rear is still on there, still doing fine. Don't kid yourself. The IBR is no different. It's just a day longer and has different rules, it's still just another rally. And I am not diminishing your ride or anyone else's. Sit there, twist that, get the bonus, repeat.Eric, I don't know how you're qualified to make that statement since you haven't actually run in the Iron Butt Rally.You'd have to be a fool to run multiple tires during a multi-day rally. You have better things to be doing than sitting around a bike shop waiting for them to mount a tire. :yahoo:
Absolutely true! And it handled like **** for how many of those miles? Sucked in the wet for how many of those miles?I do know that can run the entire length of the IBR rally on motorcycle specific tires (e.g. the ME-880) even if you're a big guy with heavy rally load. I did this in 2007 with rubber to spare.
It's only money. And you bet that is a very workable solution to the problem of not having a tire that you know will last the entire rally. Many have done just that.I do agree that sitting around a bike shop waiting to mount a tire is lame, but it's so easily remedied by having a spare rear rim with a tire mounted and ready to go shipped to a known checkpoint or stop. Takes about 15 minutes if you don't dither. I did this in 2009 and was the idea way to go as I had known good rubber the last leg to not worry about.
:rofl: At least I did my own testing rather than make a decision based on a data point of ONE.If anything, I'm increasingly convinced with the latest data point that you'd have to be a fool to run a car tire on the FJR in a multi-day rally, on a ride, or anything that isn't straight down a drag strip....+/- <5 degrees....as car tires are designed for.
They look just fine. At 36,600 when I pulled my first CT off, (the same version of Bridgestone BT-019 Grid that Doug was using), I had no dust, no chunks, zero indication of damage or fatigue inside the tire. Nothing out of the ordinary for a moto tire coming off a wheel at 6-10k, except that this CT was coming off at 3.6 to 6 times the mileage. Pictures were posted to this thread at the time.Just a question in furtherance of understanding the rim crack and interior sidewall damage on Doug's CT:
What do the interior sidewalls look like on CTs (or on the same tire Doug was using) that have been replaced when the tread is worn out?
Yes. There is no indication that any other event had ever occurred with that tire that could have possibly caused the damage to the inside of the sidewalls. I even had a low pressure event on mine down to 20 psi, plus two flats where I ran freeway speeds for a brief period, (3-4 miles at 65 mph), w/o any indication of damage. Doug was going much slower and the centrifugal force was not sufficient to keep the tire round, rather than running on the partially collapsed sidewalls.I mean, is anyone sure that the interior sidewall condition on Doug's CT was the result of 1 mile to the Ranger Station or 15 miles riding after he began to feel something wrong?
A reasonable question, but also one that has been discussed in considerable depth earlier in this thread. Real world use suggests that the CT is more than adequate to the task. Not to mention that lateral loads of CTs mounted on car wheels is significantly higher than in moto use. Think skid pad or hard cornering where under low pressures it's not uncommon for people to actually fold the tire over the car wheel and lose air pressure. Auto crossers typically mark the sidewall of their tires with white shoe polish to see how far their tires are folding over and thus determine if more air pressure is needed.Since a CT isn't designed in anticipation of having the car wheels on which they're expected to be mounted being torqued away from parallel with the road surface as much as happens in a MC application, is there a chance that CT sidewalls (or those of the brand and model Doug was using) might be inadequate to withstand the sidewall fatigue resulting from MC use (such that it might become unsafe before the tread is toast)?
Unknown, but it appears unlikely that the crack formed after the deflation event. It may, or may not have gotten worse during that 15 mile run down the mountain. But in absence of any other explanation for the tire losing pressure, it suggests that the crack existed prior to the deflation event and simply got bad enough to cause the loss of pressure in that untimely location.And a secondary question: What role did the condition of those sidewalls play in the resulting wheel crack? It seems that much of the discussion assumes that there was an impact that caused the crack, maybe that such an impact or other cause occurred after the tire was deflated. If so, what was the cause of deflation, and was the deflation instrumental in the wheel sustaining an unprotected impact?
Hence my use of the term "increasingly". I decided it was stupid idea LONG ago. The new data point is just more popcorn for the show.:rofl: At least I did my own testing rather than make a decision based on a data point of ONE.If anything, I'm increasingly convinced with the latest data point that you'd have to be a fool to run a car tire on the FJR in a multi-day rally, on a ride, or anything that isn't straight down a drag strip....+/- <5 degrees....as car tires are designed for.

P.S. Matt - Dude, tongue in cheek mean anything? Don't take every little poke on the forum that seriously.
Fair enough. I'll still stop and help you with your flat next time you get one. Try to avoid the critters, eh?P.S. Eric - Dude...don't take every little observation about Cheap Siders on the forum that seriously.

New first hand data is always welcome. Anyone wear one out yet? If so, how many miles?Yes the Hankook Ventus 110 is 1/2 narrower than the listed specs, we tried a Exalto on the Honda ST1300 and it would't fit in the swing arm but a same size 205/5017 ventus does with 1/4" to spare on each side . There are at least 4 of us with over 50k total running the Hankook and it does work great within its limits !
Are you getting the same amount of grief on the ST-owners forum as darksiders are on this forum?Yes the Hankook Ventus 110 is 1/2 narrower than the listed specs, we tried a Exalto on the Honda ST1300 and it would't fit in the swing arm but a same size 205/5017 ventus does with 1/4" to spare on each side .

I'm pretty sure doctorj the darksider ST-owners are also going to burn for eternal damnation in Hades with the rest of you cat blood drinking and wife swapping Car Tire Cultists, I will have to check in with the Vatican to confirm this. Filthy Heretics!Are you getting the same amount of grief on the ST-owners forum as darksiders are on this forum?Yes the Hankook Ventus 110 is 1/2 narrower than the listed specs, we tried a Exalto on the Honda ST1300 and it would't fit in the swing arm but a same size 205/5017 ventus does with 1/4" to spare on each side .
