Because no one wipes out on motorcycle tires. If you want to ride so hard that you risk a wipe out, take it to a track. Otherwise you are endangering other people on the road.

As for why they ride, if you have to ask....
Big difference between a car and a motorcycle: mc only has two wheels/tires. Huge difference in traction especially in inclement weather. No bike will ever match a car in terms of generating g forces on a skid run.

I will accept that. One question... since the car tire has more contact area would that not make it more stable during normal riding conditions? Not the knee dragging, peg scraping, unsafe riding conditions described by some posters? With regards to inclement weather, most riders jump in their cage making that arguement a mute point for both of us.

Riding on the dark side is one of those never ending threads. I know some riders who swear by using a car tire on their bikes. One rides all winter in NH in snow storms with a Suzuki DL1000. The problem with saying normal riding is that in normal riding bikes lean to turn or go around curves. As soon as that happens, the car tire starts to leave the pavement and doesn't have the profile or side wall of a bike tire. In straight line riding, sure, there is more contact patch. Many do it so for them it's fine even if they have to deal with some handling issues. There is a previous thread that shows a car tire on a Rocket III with a camera aimed at the tire while riding. I'll have to find it. Another consideration concerning tires is how the rear matches up with the front.

Here's a video of a Rocket III with a car tire. Also check the video on the right column, 4th from the top at this Youtube site. Many comments to read from viewers. For every rider who says car tires are for idiots, there is one that actually uses them who says otherwise.

Is that video an arguement for or against the use of a car tire?

For the Rocket rider, for. I will probably never own a bike that would be a candidate for a car tire so not an issue for me. There's only one way to find out how the tire will perform and that's mounting one.

I'm not ready to go to the Dark Side myself, but I have yet to see anyone who has tried car tires say anything negative about them. Evidently they work pretty well.

I guess you missed my point. I won't argue further.

Here is an interesting article in Cruiser magazine on the issue.

http://m.motorcyclecruiser.com/tech/...les/index.html


But here's the problem; Car tires are fundamentally unsuited for use on motorcycles. Moreover, that's not just my opinion but also the opinion of every tire engineer I've ever discussed this with. We all understand that the dynamics of motorcycles and cars are vastly different. As such, they demand different types of tires and at the risk of great over simplification I'd point out that if a car type tire worked well on a motorcycle everything from a moped to a MotoGP bike would be wearing them as standard equipment. The fact that they can even be used on a big cruiser says more about the way those bikes are designed and ridden than it does about the suitability of using a car tire on one.

According to most of what I read on the Darkside (and similar forums) none of that matters. Some dispute the facts provided by the tire manufacturers and at least one guy said he didn't much care what the facts were. He liked his car tire and even if side by side testing showed that the motorcycle tire was superior, he was going to keep on running it. It's hard to argue with logic like that.
