why ???

Is it that much of a saving to risk your life or insurance policy by fitting a non bike designed tyre to a bike ? Different carcass structure, sidewalls different, grip different, side angle of tyre different.

For the few dollars you may save ? I don't really think it's worth the risks. Just buy a harder compound tyre if it's that big an issue. If you don't do a lot of k's then the tyre itself when it gets too old will become hard and not as efficient anyway. You would have to only be looking at maybe $50 difference if that over a couple of years in costs, and if that's a big deal then you shouldn't be riding anyway and just take the bus.

Just my 2c.

enuf with the fear mongering and unqualified spouts

with millions of miles with car tires on motorcycles and I'm sure a few accidents, there has never been a report that an insurance company has denied a claim

your estimate of saving only $50 over 2 years is a little off as well, I ran a car tire for 3 years and over that time I saved nearly $2500 in tire, and mounting and balancing cost, without even thinking about all the down time that woulda happened had I choose to go thru 8-10 motorcycle tires instead

that said, I went to the darkside as a winter experiment to ride on snow & ice, an experiment successful beyond my wildest imagination, I have since chosen to only run a car tire in the winter as a car tire isn't that great as an off road tire, if I stuck to street riding only (paved & gravel roads) I would probably stick to the darkside for all 4 seasons

why does somebody always try to muck up darkside threads, nobody is trying to convince anyone to do anything they don't want to do

Gyps, the 2 cents is about what it's worth. Another never tried nay sayer.
If you have a negative opinion, try it first and give first hand experience rather than a naive opinion.
I hold out on an opinion because I haven't tried it yet, i do know several folks that run those tires and swear by them.
Tell you what, be a good religious cult and with hold medical attention to your children because of your faith.
Both are equally uninformed.

I was typing a reply very similar to Randy's when I saw he beat me to the punch.

I'm not a darksider. I've never tried it, and I probably won't. But every time this subject pops up on a motorcycle forum, there is always someone predicting absolute doom and financial ruin, and lots of scientific sounding explanations about tire design and construction invariably offered by someone without any sort of training in a field that would qualify them to make those sorts of assessments.

You know what I've never heard? One single account of an accident on a bike that was a proven to be the direct result of the presence of a car tire on a bike. Not merely a crash involving a darksider, but one where someone with the proper qualifications actually arrived at the conclusion that the car tire was the cause of the accident. Darksiders log thousands and thousands of miles year in, year out; they prove their assertion that it's safe with every single mile they ride. They don't claim it's better; only that it's a safe and cheaper alternative to a motorcycle tire, especially for long distance interstate riding. And with as many doomsayers as there are on forums when the darkside subject comes up, not one of them has ever offered proof as to why it's unsafe. Unsubstantiated, unsupported, unqualified opinions don't constitute proof.

Ah no fear mongering or predicting doom and gloom, just my opinion which obviously doesn't count as much as anyone else's i guess.

For what it's worth, over here if you have an accident and you DO NOT have a motorcycle tyre on your motorcycle then your claim WILL be denied. They will use ANY excuse to deny a claim on insurance if you unfortunately have to claim. We have so many stupid rules and regulations that practically anything you change from standard is more than likely to be illegal.

As for not trying it, well yes I don't want to and I'm never going to and I guess 30+ years of riding doesn't count for anything.

Not trying to stir anything here, just thought this was an open forum for people to discuss things and ideas but maybe I'm wrong.

Just my 2c worth.

LOL, I think the phrase "risking your life" in regard to riding with a car tire could be easily construed as fear mongering, since there's zero proof that doing the darkside thing poses any risks beyond the normal ones associated with motorcycle riding.

And this is an open forum. There are lots of discussions on here with lots of opposing viewpoints. Being an open forum doesn't mean that you can present any idea that you have without it being challenged. Presenting opposing views is pretty much the point of a discussion. There are LOTS of guys on here with 30 plus years of riding experience (I'm one of them) that may not agree with you, and will present their opinions to counter yours. If your comfort level is compromised when you don't have universal agreement for what you post, then you're liable to experience more discomfort down the road. There are a lot of guys on this forum with a lot of knowledge about a wide variety of subjects, and they'll challenge you if they think you're wrong about something. It's not personal.

Your opinion is just as valued as anyone else's. Your sugestion to take a bus might have been a bit misunderstood. :wink2:

I find it curious how all the forums can politely debate knobbies vs track-day tires and the finer points of choosing a 80/20 over a 50/50 depending on how a bike is being used but this choice seems to fall into a adversarial arena.

I think most of the folks who read these discussions from the sidelines are just curious. I have one of those longitudinal four BMWs. It's a bike that you shop for in the husky aisle. It has about 140hp and I can't put together two back-to-back 10 day trips on a rear tire. So I leave a lot of tire on the table every year. So this fall I will at least consider one.

I have spoken to a few IronButt guys and the ones that try them seem to stay with them - for the style of riding they are doing. I followed a couple of those guys down out of Telluride who didn't seem to be struggling at all.
PS: I have seen a Joey Chitwood stunt show. it left a big impression.

I wish I knew how dangerous and horrible the DS was before I put 130,000 (and still going) on DS tires.....
I'm curious about the insurance denial claim....so nobody puts after market parts on their bikes? I have a long long list of non OEM add ons for both bikes. I'm assuming that doesn't happen in Oz?

Can you provide a link to insurance companies not insuring car tires. Thanks

From the looks of how gspy4u is spelling "tyre", he is from Europe. They enjoy very strict laws on stuff like this. For instance, if the tire on your bike isn't on the "approved" list by the bike manufacturer you are liable for all sorts of things. Including the insurance not paying.......

There is enough evidence out there to convince me that car tires are not a danger on a motorcycle. Those that have no experience and have opinions, just don't really know. As far as buying a hard compound tire, there simply are not that many. They may not be a "safe" as a car tire for instance. Just saving money? Well, there are some tires for under $150 per set on a V Strom that work. But not very well. I don't know that they would be any safer than a car tire. At any rate it would not be all about saving money for me. It would be ALL about the mileage I would get. Right now I can put on a new rear tire and make one trip on it. The next trip would have to be short for the tire to last. If I could get 15,000 miles and more on a rear tire with predictable and good handling, I would consider it.

What make/ model tire did you mount?

How hard was it to mount the second side? Did you succeed with your spoons or get it done with a mount bar and the rim in a tire changer?
Also, how wide is the tire on the widest point please? I like to see if there is enough clearance on the V2.

Thanks

that is hard to measure without a friend and a caliper, widest point is at the sidewall when your squishing it down with a load

The tire is aGoodrich Gforce Comp 2 A/S

I did forgot to mention in the video that you have to cut a bit of the tire chain hugger to clear the tire. It barely rubbed, but i took some tin scissors and cut a little triangle, and that was all it took.To get the second side, i needed another set of hands and really long tire levers to get leverage. I dont recommend it, get a auto shop to mount it.

Thanks! Can you guestimate how wide the tire is?

I run a Sumitomo 205/50 ZR 17 93y my fourth on this bike. My last tire got a sneeze under 14,000 miles, I think I could have wrung out the 200 more miles for an even 14,000 but I was going on a trip and needed new rubber. Also, about 3000 of those miles was two up.

I pay $72.00 for the tire.

hmm, my general altimax arctic (same size 205/50-17) had no problem clearing the chain guard or top run of the chain, it's closest point to the chain was along the bottom run

Since im new to the darkside. I was recommended a 205. But, why a 205. Wouldnt a slightly thinner tire work as well?
