Its up to you of course but I think I will stay with tires that are engineered to do the job. Motorcycle tires are designed to disperse water and maintain grip while cornering where car tires are designed to disperse water in the center of the tread and not so much on the sides of the tread. Just my 2 cents.

You might want to go back and read Wexy's comment on their grip in the wet.

On a CT if the water is dispersed from the center then where does it go if not out to the edges for dispersal? Same as a MC.

In that video it shows a small contact patch in a lean but that can be manipulated. I can do the same thing by over inflating the tire first. Now in other post where folks have actual ran a CT they have posted that they run a lower pressure in the CT versus a higher pressure we run in a MT. CT at 36 psi versus MT at 41 psi. A CT is constructed with more belts normally versus a MT, has a higher rated load capacity and much stiffer, thicker sidewalls than a MT. Hence some's ability to actually ride a flat CT on a bike to a repair location at a reduced speed where as with a flat MT you go no where till it's repaired, replaced or trailered home. Also some of the newer CT's have a more rounded edge than others, like the Kuhmo run flat. Getting my MT's and CT's mixed up hence editing.

I have been running one on my bike for over a year now.It felt weird to me a first handling wise but added a few more pounds and now it feels just like a Mc tire. Nobody has been able to mount one ona 1500? what size wheel is on the back?

It's not so much the size of the wheel, as the sidewall clearance to the swingarm. Just not enough space. there is also differing opinions on the 1500's wheel having the correct bead retaining lip to secure a radial tire.

I have had a car tire on my VTX for more than two years with NO ill effects and really good handling characteristics. Just my two pennies.

There's also the problem that the 15 inch rims on just about all motorcycles are not a true 15 inch. This includes the GL1500's. Over on the sidecar forums they discuss this in more detail and also about folks have actually been killed trying ti fit a 15" CT on the 1500's 15' rims. Too much air pressure needed to get the bead to set.

Michael, I had forgotten that important point. Thanks for bringing that one up.

A while back there as either a link or an image posted. it was a contact patch chart, and it showed that with a car tire on a motorcycle when you lean the bike for cornering the contact patch does not shrink, it simply elongates. It showed that the car tire had a far larger contact patch than an mc tire when at the same angle. The only car tire you want to put on a bike is a run flat. Run flat tires have very strong reinforced sidewalls.

Actually that is not completely correct, A Z rated tire has almost as stiff sidewalls but not so stiff that it you can feel it when leaning like with a run flat. Handles much more like a motorcycle tire. I was really going to leave this thread alone but couldn't help myself.

The weather forcast for this Sunday here in Ireland is horrendous ,so it may be next week before I get the Camera mounted on the bike ,Wingnut is making up a bracket to mount the camera to the tow hitch and then I will take the bike on a good fast run on a very twisty road ,, But so far I am delighted with the grip and comfort of the tyre , Ciaran Attachment: tow bar 1.jpg (Downloaded 99 times)

Can't wait to see the video Ciaran. Maybe it'll help those who don't know grow a better understanding.

Well at least it might put to bed once and for all the fears of having a car tyre on a 1800 wing (not any other motorcycle just an 1800)

Well, you know that as long as the world is flat, those fears will never be put completely to bed. Too bad nobody here remembers the days when putting a gas motor on a common bicycle was considered pure madness.

I made my mind up to go over to the dark side a while ago. Soon as these, over priced, MC tires are worn out.......I'm making the move. That video looked good to me.

Ciaran, that particular tire on your bike almost has the same radius curve as a MC tire, (oops tyre).
