I recently had a new darkside tire installed. The old one was OK or so I thought. I have been riding with a Bridgestone Potenza G009 for about 10K miles which for me is sadly a few years of riding. I accepted the fact car tires were different and thought you just had to live with the "different feel" of a car tire on the rear. This year I wanted to have the splines lubed and inspected so I went ahead and had a new tire put on as long as as the rear end was apart. As per the advice of a few VRCC friends I selected the Champiro VP1 205/60/16. At a first glance I noticed a more rounded sidewall and a little more of the tire appeared to touch the ground when on the kickstand. I have been out on 2 rides with the new tire one by myself and another with my wife. The new tire doesn't have the odd feeling of wanting to high-side during cornering like my previous tire. Even though these tires are the same size I definitely have found myself scraping the pegs more these last 2 rides. I don't think it's a confidence in the tire as much as a rounded sidewall difference. Every Spring in my first few rides I have felt like I had to get familiar with riding again, not the case this year. Slow speed maneuvering, big corners, and twisties all appear to be easier. This tire is substantially more like the bike tires I rode on years ago. Thanks to all for recommending this tire, the Champiro VP1 is an excellent choice for a Darkside option.   |

I never thought about it but i drug pegs a LOT more when i had my champiro. Great handling tire. My first darkside experience. Got 10k out of it and had a couple miles still left but it was time to lube the splines so i changed it. I currently have a primewell valero touring and hate it. This week its coming off and a michelin mxv4 is going on. Here is a pic on the dragon with the champiro  |

Thanks for the info, Dan. I'm on my second darkside rear tire and just recently went darkside on the front, too. I haven't really found any situation where I wish I had a motorcycle tire on the rear. My hope is to get 15-18k out of the front tire.
You have a very nice looking bike. I hope to see it in person sometime. I understand we have some friends in common. I'm north of you, by the way. Rush City.

Fake News. take away the useless curve at the top of the car rim (only there for curb protection) which gives zero support to the tire bead and it is basically the same height as the m/c rim. It was the tire association yrs ago which did those slight changes to both rims to help the m/c tire industry. riders where always using car tires a lot. millions of miles of car tires on m/c rims proves there isn't a problem.

They are fake news. Despite the repeated use of "dangerous" and "unsafe" there are no examples of failures by these unsafe and dangerous tires resulting in accidents. This in the face of not hundreds or thousands but millions of miles on "not designed for motorcycle" tires. The tires in question provide better traction in rain and in heavy braking. The ones who are a riot are the ones who insist on beating the drum based upon theory while ignoring the evidence. I have a list of riders on "car tires" that I would encourage the detractors to try to keep up with. Interestingly the rear tires I put on my street bike in the late sixties looked a lot like small car tires. We survived.  |

Yep...lots of fake news out there. Here's more: http://tinyurl.com/mqrj5qzRe: Rain and braking: "TrafficSafe examined the following video footage of a car tyre being used on a solo motorcycle and shared it with other experts in tyre safety. We noted the following points:
1 The tread pattern is designed for car use with the maximum volume of water being displaced when the tyre has flat contact with the road surface. Angling the tyre into corners has an enormous impact on the tyre’s ability to displace water on a wet road surface.
2 As the motorcycle leans into the corner, the tyre presents less surface area to the road, reducing the contact patch at moments when firm contact is most needed.
3 The tyre is over-inflated to 40psi, presumably in order to change the tyre profile to make it less square and thus improve cornering performance. Sudden loss of pressure from 40psi would have a devastating effect on handling."Something else to consider: "Finally, we spoke to a UK insurance company on whether fitting a car tyre on a motorcycle would affect any claims. The spokesman said “Such a change to the standard specification of the motorcycle would require prior approval from the insurance company otherwise the policy would be invalidated. In the event of an accident, the rider would lose the right to claim on the insurance. Under current UK law, the insurance company would be obliged to pay third party claims if the motorcycle rider was at fault but the insurance company would rigorously pursue subsequent compensation from the rider at fault”.
We also spoke to the largest insurance company in the USA which specializes in motorcycle insurance who declined our invitation to comment. TrafficSafe would therefore recommend that US motorcyclists check their policies and enquire with their insurance provider regarding the validity of their policy before fitting non-standard equipment to their vehicles."Based on theory? I think not. I don't have to put my finger in a fire to find out if its hot or not. |

I'm so sorry. I didn't imagine I would have to get down to defining terms. Theory is what someone has determined what should happen. Evidence is made up of examples of what actually did happen. By the way, at some point someone did need to experience burning his finger before the rest of us knew it would happen. |

I'm not sure why we are having this discussion. Motorcycle riders across the country have collectively logged on "Millions" of miles on car tires. If there were many examples of flaming deaths out there due to going to the darkside people would be much less likely to use them. I personally do not feel any less safe with a car tire on the rear of my bike. I was always a little nervous riding in wet conditions with my bike tires as they were getting toward the end of their life. I don't feel that way on my bike tire. Like them, don't like them, I will continue to ride with a darkside tire on the rear of my bike. If you don't like the idea of a car tire on the back of your bike keep using a motorcycle tire by all means. |

Sigh. For the "Nay-Sayers" I dare you  to look at the Database of bikes running Car Tires. http://darkside.nwff.info/?p=tiresI bet you don't even get to the bottom of the list before you realize how many bikes are doing this. Then realize the the database reflects only a small number of DarkSiders who have contributed to the list. There are indeed many, many, many more. But from past experiences even when the proof is proven in the puddin, in the end the nay-sayers will continue to nay-say . I can be assured that the 3 C/T's that have been on my bike, and the 63,000 miles that have safely been put on them that no nay-sayer will change my mind. |

Not true. You have drank deeply of the so called Kool-Aid. If you choose to call the experience of miles and miles as emotional rhetoric that is your choice, but don't try to pass your position off as common sense. Nothing could be further from the truth. |

Champiro 6,000 miles  Center has worn a tad more than sides. I had it at 38psi. I've reduced it to 36psi to try to counter the premature wear. |

Lots of us run down into the 20's on pressure.
I have read of numerous fatalities actually CAUSED by motorcycle tire faures.
I have not read of a single accident CAUSED by a car tire on a bike.

I was skeptical at first, but always willing to try something that has been proven. After running my first car tire and getting caught in some heavy rain coming back from a Myrtle Beach ride, I was sold. The car tire just Brakes better, Sheds water better, and I normally get 30K + miles out of a good Darksider. I also run double Darkside and get close to 18K miles out of the front tire as well. I have to do 3 final drive grease jobs on 1 rear tire  . My Buddy just went Darkside on his Wing and is thrilled with the handling, he went thru bike tires every 8K miles or so, and was sick of being ripped off. We just all got back from slaying the Dragon up in NC, and we all rode on Darksider's. So pushing them to the limit on those roads with No issues, is proof enough for us. I have over 60K miles of experience on a Darkside, and never going back |

This was a MOTORCYCLE tire from my F6b that heated up after losing a mushroom plug I put in it due to picking up a nail. It blew into my face and chest from 3 feet away after I just aired it up to 36psi and was pulling the gauge away.  Sooooo, I'll take my chances with a tire originallly designed for cars from now on. My new tire is a Bridgestone Driveguard Runflat also which gives me more peace of mind. |

I have decided that it is not worth my time to argue with the folks that have something to say about those that choose to to run a car tire. I have never heard of a failure or an accident attributed to a car tire on the back of a motorcycle...and I have never heard of an insurance claim being denied because the motorcycle had a car tire on it...like someone else mentioned I would challenge some of the nay-sayers to try and keep up with a few of the car tire shodded Valks on this board. So WTF did I just do, wasted time concerning someone who chooses to not run a car tire... I recently had a pretty serious accident that can be attributed to a car tire...well actually 4 car tires...mounted on a car that hit me and then fled LOL My car tire shod Valk...with a 170/60-17 up front (a rear tire)  |

You got to admit that the charge is funny:  I ride MC tires just because they handle better and is a better fit for the way I ride. I don't think a good DS tire is inherently unsafe and the longer mileage is definitely interesting. Then again, riding motorcycles is not a cheap past time... |

Tens of millions of safe miles when you consider all the big cruisers running them now. They will definitely stop you better and launch harder should you want to. Last one Hell of a lot longer.
Both Lesa and I run DS on the Valks we own. They are more than safe as far as I am concerned.
Good thing we don't hang out at Starbucks for our information.
