Well my C14 is up on lift and getting ready to be transformed.  This summer I have been riding very hard on my Goldwing. I have over 15,000 miles on a car tire on my wing and I love it.  Never had a bike that responded as well.  Handling is unbelievable.  I have a Pirelli 205 50 17 that will be on the Connie tomorrow. I think it will be great but only time will tell.  Will post back here in a couple of days as to how well or not it works on this bike.  I have looked around and have found that most Connie riders do not believe in a CT.  I was that way for years on the same opinion with a Goldwing until I tried it for myself.  I just cant wait to ride the Connie on a Wonky tire.

You, sir, are mad whack! ... just like your car tire brethren!

No comment...

(Well, I guess saying "no comment" is, itself, a comment)

I think a 205/45-17 would give a tad more clearance while maintain other requirements.   

they're called car tyres for a  reason

Tip of the hat to the OP. Am looking forward to a detailed report on his experience doing this. I have gone to the darkside for the past few years on my other bike (a middle-weight V-twin) which admittedly is used for more leisurely rides than the C14. No problems with the handling and love not having to change tires every year. Are those run-flat Pirelli that you are using? I'm wondering if the stiffer sidewalls are better or worse for a motorcycle.

      Can you provide pictures?

Once you join the Darkside who knows what's next.....

Dammit, you've gone and uncovered my daily morning ritual. 

A a Wing owner, I've been considering a car tire also. Just wore out a pair of B-stones in one 4+ week trip. What did you have on the wing?? The size mentioned is, I assume, for the C-14?

  It is on.  I just went out made a 10 mile shake down, came back and checked things over all looked good.  Went back out and ran 50 miles.  did not push bike real hard just enjoying the ride.  Did a combination of country roads, state highways, and Interstate.  YES  I like it.  I figure right now I have 1 of the dozen best riding and handling Connies in the country. The others have a car tire too!  It rides smooth and handles better than any Connie I have owned.  This is my third 1400 and I had 3 1000's.  I will say this is not for everyone.  It is different especially at slow speeds. Rear tire will chase grooves and risers in roads at slow to stopping speeds.  I might be a CVRAZY old man.  But I sure have a big smile on my face right now!  Pics very soon.

 On wing I run a Pirelli P1 195 55 16 run flat.  On the Connie I cant get a P1 in the size.  So I went with a Perelli P7 205 50 17. it is summer performance not a run flat.  Spoke to another Connie rider on a car tire.  He said he had never used a run flat and was happy. Time will tell I may step up to some run flat next time but not sure.  Just look for rounded edge.  I don't like the square cut edge tires.

pics,

looks like you might need a wider mudflap

It is BIG  for sure.

Check with .... Blue One.... he makes a rear extender that looks like it would work...

Here is the previous thread:  http://www.zggtr.org/index.php?topic=6116  has some noise, but an interesting re-read.

  Just to let my thoughts known I posted this.  I in no way am trying to or will ever try to talk someone into running a car tire.  That is a personal choice. I was dead set against it a couple years ago on the Goldwing boards. I rode several times with guys that ran them and one day I decided to just give one a try.  At first I did not care much for it.  After the first 500 miles I started to like it.  The Connie is nothing like the Goldwing but so far it feels OK to me.  Time will tell.

So, the initial post was made on Friday the 13th. That alone took guts. Running a CT on a "Sport bike with bags" also takes some intestinal fortitude.

That being writ, I say bravo to you! Experience is the only way to truly prove any theory/idea.  What I am trying to say is that when there is a genuine need to try something different it must be done or you will never know for sure if it was a good/bad idea in the first place. (My opinion) There are many arguments for and against running a CT on this, or any, motorcycle.  Considering that many riders have crossed over to the Dark Side and haven't returned says something.  Doesn't it?

Since I am a potential convert to a CT I would like to know about the process of making the switch.  Stuff like difficulty with mounting, balancing, tire choices, side clearances, and speed rating to name a few.  Anyone?

What air pressure are you using?    TPS system functions the same, right?
