Re: Car Tires - What people think are the negatives or want to debate
Attack the argument, not the individual.

For 1000 miles of straight road, in hot weather and on a fat arsed bike, I can see the logic in this.RonH said:Hot weather, straight down interstate.......
I know this is old as hell but I finally got around to running a K60 on my S10. I got maybe 8K miles if memory serves while commuting, local playing on and off tarmac and one smallish trip {maybe 2K miles} so the CT which I beat on a lot harder lasted considerably longer. The CT was on a DL650 so not apples to apples but I know how I treated that CT on my DL650 and I will tell you right now, I treated it a lot worse/beat on it a lot harder than the K60 on the Tenere.dcstrom said:A K60 rear will get you there AND BACK, with tread to spare, and handle the dirt much better while doing it. So the mileage argument really doesn't hold water either. Somebody, forget who, said they had a CT for the trip to South America because they couldn't get MT's on the way down. Not true at all. Run K60's and you'll get Prudhoe to Lima or Santiago on one set. K60's have been available in both cities for a while now. Also available at a few other places on the way...
Not that I would run CT's on my Tenere but I have had two sets of rear K60 rubbers on and if I could get at least 8k on them i may have kept buying them.Judd said:I know this is old as hell but I finally got around to running a K60 on my S10.

Traction wise, no contest,,,,, the CT offered traction, a lot more, than the K60 in pretty much every situation except most off tarmac situations. I say "most" because the CT had roughly the same/maybe more traction in the sand and decidedly more traction on typical hard packed/maintained dirt roads like your run of the mill forestry service road. On tarmac there is no comparison, the CT beat the K60 when dry, when wet, when cornering, under acceleration and when braking. Matter of fact, I think the K60 is right up there with the ME880 and "shittiest tire ever for playing in the twisties". The only situation where I would ever be tempted to run a K60 again would be on a trip to Alaska or the like where you would be needing a high mileage tire that also worked OK off tarmac, especially muddyish conditions. Even then, I would rather run a E07 or a CT.
Handling comparison is a moot point since the K60's lack of traction on tarmac would put the damper on the festivities well before the CT's handling deficit showed up. If you regularly run K60s and you are worried about a CT's traction on tarmac,,,,,,,, don't. ::024::

You're funny! You have no direct experience with this stuff, so leave it alone or try it yourself and learn first hand. Apparently you have never talked to an insurance investigator either. The tire is DOT approved, which doesn't really mean anything. Round and black with some tread is about as far as any insurance person will look for. And an investigator won't be looking, or care, about the tires if that isn't a direct aspect of the incident. And really? Started with the Goldwing crowd? You are not well informed. This has been done as long as motorcycles have existed. HDs were running car tires back in the 50's and 60's routinely. Before that, motorcycle tires were essentially the same as car tires in design, just narrower. Many a flat tread design for motorcycles existed long ago.Madhatter said:I'm not impressed , for general riding a dangerous tire set up.... when the insurance checks your wrecked bike wonder if they might have an issue non DOT approved tires mounted on bike.... three wheelers and other machines that don't lean to turn can use a rear tire like that but a motorcycle , this thing started with the Goldwing crowd . wonder how many have crashed out with this set up .... and just because a few get away with this doesn't make this safe....
We built a lot of Choppers back in the 70's with car tires on the rear and one of the first things we learned was to not put a 15" car tire on a 15" MC rim. 16" & 17" car and MC rims are almost exactly the same diameter, but a 15" MC rim is quite a bit bigger than a 15" car rim. I have mounted a few 15" car tires for riders in the past few years (after warning them about the difference), but I refused to seat the bead. I told them they will have to take it somewhere else to put air in it. Most of them end up busting the tubes before the tire pops on the rim or they just give up and put on a MC tire.ace50 said:The only size I won't CT again is a 15". Design is too different from a Cycle rim. Very hard to get on and too much pressure to seat the bead.
16" is a breeze.....so to speak.
Because changing a tire every 5-8K American miles is ridiculous.Nikolajsen said:I did read it all, but I might have missed something, or misunderstod it....sorry...I have one question
Why?
Actually, I've done quite a lot more research than you ever will on this topic. I've spoken to family members of two riders that died in crashes, that happened to be riding on CTs at the time. One was multi-vehicle and the CT had no part of the crash. The other was tire related, but the rider had only minutes before the crash told other riders he dropped his tire pressure to 5 psi. It wasn't the tire that caused the accident. It was the extreme low pressure that led to the tire coming partially off the wheel.Madhatter said:Ericv, your statement that no Goldwing or fjr have had no ct failures is odd , America is a pretty big place you can not possible no whats happening with every rider of said bikes in America .
But not crashes directly attributed to the CT. People crash all the time. Some blame the bike or the stuff they bolted to the bike. A very high percentage are rider error. After that, often it's conditions and animals.ive done a google search and once you get through all the darkside propaganda you can find more than one example of crashes caused by ct
You're missing the point. So what? My needs when I did this were not the specific design parameters of the group of engineers that designed the bike. I knew that. I also knew that I wasn't trying to go as fast as possible around corners or riding the bike at 100% of it's capabilities. There is a huge margin of error if you ride reasonably on public roads. I was looking to improve a specific facet of my riding needs and was prepared to accept some limitations. If you read the thread I started, you'll also see that I was fully prepared to say it was a failure too. I had no need to prove it worked. I wanted to see if it would and the only way to do that was to actually try it myself.but motorcycles work best as designed and that means proper m/c tires
I'm not upset with you, I'm only trying to educate you. And it's only an "idea" to you. It's a proven concept to me. I proved it with my own bike, my own experiments and my own risk. I can tell you exactly how the tire dynamically changes during riding and cornering. Most people assume they know and are nearly always incorrect.when our key boards cool down about this topic , it might or might not , I hold no grudges because someone disagrees with me or I disagree with them .... its a debate on ideas
Seriously? You really believe that the owner's manual is the gospel? I've worked for OEMs. I know exactly what goes on when the manuals are written. The primary purpose is for the OEM to cover their butt legally, secondary is to provide some basic info to the owners. It's about liability. And are you really inferring that you never, not once, ever did anything not fully authorized by the owner's manual? If you say yes, you are mistaken. I don't know you, and can still safely say that. Read your manual. The only approved tire is the one the bike came with and sometimes one other. All other tires are not approved by the OEM, so you're on your own if something bad happens. Never mind just about any other change or accessory you may do.every owners manual of every two wheeled m/c specifies the use of motorcycle tires , and that is from every m/c manufacturer that has ever been on planet earth.... are they correct
Again, you're just wrong. Do you have any first hand experience working with engineers on projects and products?you darksiders say they are not ,millions of dollars spent on engineering degrees and over a hundred years of m/c manufacturing doesn't count for much
I hear that a lot from people that don't even understand what they are saying. Did I say I was trying to go as fast as possible? Did I say I wanted to go out on the race track? No, I didn't. That isn't anyone's goal when they decide to try Darksiding. Please present reasonable arguments if you persist in attempting to rationalize your unsupported opinion. GP racers don't even ride on tires we can buy in most cases. And if I had their tire budget, I would have never worried about how long tires lasted!they should try them on moto gp bikes
Enjoy your bike your way. Just resist the urge to tell others that you know that what they are doing is somehow incorrect or unsafe, when you haven't actually done or tried it yourself. And you know what I mean. No "if they rode off a cliff, would you do it too?" like someone's Mom arguing with a child.I enjoy this forum and I enjoy this debate , I even learn things at times ...... my wife might disagree .... I will close with this, that a car tire mounted on your bike works for you , that's a very good thing......
