Hey Dan, I was wondering how the Vredestein is holding up on your Concours? I am looking at options on my 2005 Concours. Both front and rear are looking a little thin on the tread, after only 7,500 miles, and prices here in Fairbanks are ridiculous. Chuck ( cam_javaman@hotmail.com )

Chuck,   Have had the Vrdestien tire mounted on the stock Connie wheel for a few months.   BUT have not used it yet. The Federal tire with 15k mi is going fine.   The Vred is a light truck/van tire so not sure how well it will work. Maybe to stiff to conform to road surface compared to the one ply sidewall constructed CT's I have been using. More $ too. I have buyers remorse and i haven't even used it yet! Ha.   Dan

Think either of these tires would fit?  I can't find them anymore on that site, sorry.

 Tire ref # ??   The link would not allow access directly to the tire.

First this experiment has worked for me.I have had good fortune and overall positive results using CT's for 35k mi. It is not recommended by any manufacturer or endorsed by any group. My reports are not intended to rally anyone to try using car tires on a MC but to explain my experience and experimentation.     Finally got to get the  stock 16' wheel and Vredestein tire (mounted months ago) on the Connie and put miles on it.   This tire is more like a MC tire in that it has a more stiff tread and sidewalls compared to the other two CT's I have used because of more plies in both areas. It is a light truck/van tire.   It mounted fine just as the other CT's did. I use 35 psi tho 40 may give better tread life as the others CT's wore slightly faster on the side tread block. Last CT used gave me 19k mi before getting to the first tw indicator on the left side tread block. I am hard on tires and usually get a max of 8k mi on a rear sport radial MC tire.     This Vredestein is approx 9% taller resulting in approx 9% overdrive. Engine is less busy at hwy speeds and first indication is of improved fuel mileage. Slight reduction of the Connie buzz.   I do have some clearance issue as it is minor rubbing on the inner fender at the top that may yet be resolved.   Photos of rubbing:   photos 37 thru 47  http://rides.webshots.com/photo/2230756090033639341nEEdLk   First day of cautious riding was 25 miles low speed town riding. I could hear the tire rubbing over moderate rough pavement. (bumps)   Second day of riding over the Cascade mountains and back of 260 miles including twisty roads with elevation changes.   Rubbing of the tire shoulder on the inner fender near the top where the front and rear 1/2 fenders come together and at that point the fender narrows. This was a minor issue after adjusting preload on rear shock to 3 of 4. I have the ZZR1200 rear shock on that has a mechanical preload (not air as in the stock shock). Using a stock shock will likely have a version of the tire to fender clearance issue.   Above photos taken after the ride. No apparent damage to inner fender from rubbing so far. Eventually the rubbing will abrade some of the plastic fender thickness. I want to see if the fender can be raised... not sure. Normal riding and cruising over light bumps and undulations did not result in any rubbing noise. The exception ids the front lower rubber fender flaps that sometimes touch the outside edge of the tire tread and this is a very minor issue IMO.   Bike handled fine and cornered fine. I have not yet put it into the max sporting mode but rode thru corners at a spirited pace and traction was very good. Speeds below triple digit was stable. More stable that the two prior CT's used. The prior car tires took more initial input to lean over and maintain lean, not radical but a more firm hand. This Vredestein takes slightly more again/ Like riding a different MC. I get used to it after a while and it becomes more natural.   First impression was that the Federal  (2nd) car tire is a better car tire for the sporting mode and max lean traction. The Federal with less tread plies also soaks up harsh bumps better than the Vred and any MC tire.. Still this Vred tire may yet to prove to be better than a MC as far a traction leaned over, more milage and testing required as it is progressive. The Federal was way better traction in all conditions and attitudes than any MC tire I have used including sport radials.     Note: after removing the touring weight after the last 300 mi trip around Mt Rainier and with the ZZR shock still set at 3 of 4 I did not hear any rubbing sounds while riding around the local roads today.      Dan   ;)

 Forgot to add an important item when installing the wheel on the drive with the 16" Vredestein.   The tire sidewall touched the right swingarm before the mating gears became aligned or flush. This would not allow the wheel drive to slide together.   I ended up removing the drive hub. then sliding the wheel onto the drive hub spline and lastly bolting up the drive hub.   Kinda stumped me for a minute but the solution was simple. :)

FWIW, Vulcan Tire says that it will start to carry Kumho Solus KR21's in 165/80R15 soon.  I just put 4 of these KR21's on a Corolla and they seem quite grippy.  Vulcan also carries the Federal 165/80R15.  I'll probably darkside my connie this spring.  :eg:

 Thanks for the tire availability update!   On my 4th CT and still believe that is the the right rear tire for me.

 Onlinetires.com   Best price so far on the Federal brand 165R 80 15. Last I checked none in stock,, now?   Vulcan also back ordered on the Federal until Jan.   Vulcan site shows Kumho brand 'coming soon'?   I do not know of one who has used a Kumho tire on a Connie-10 tho read positive reviews on using one on a power cruiser I recall.

Yeah Dan, The Federal seems to be available from online tires but it's 50% shipping for one from CA to NJ $60.17 total  :(  Still cheaper than a moto tire with more than double the wear, eh? :)

  still,   That is a better price than the $87 I paid at the local tire co, Les Schwab.

Can someone with a car tire installled on their C10 give us a weight for the rear wheel combination?  Just curious how much more mass the clutch and final drive has to deal with when this bigger tire is installed on the bike.

  Jay,     Thought about the weight factor but never weighed the diff.   Carrying the shorter 15" wheel which is wider with the passenger ct mounted on it 'seemed' about the same.    The stock wheel with the light truck Vredestein tire 'seemed' heavier than the mounted stock mc tire. Not much but a couple #?   Unsprung weight is a factor but the additional stress on the drive train is not a factor IMO.

Danodemotoman,    Are you going to be at the National in Tomah, WI?  Pictures are great but I would really like to see this modification on your bike.

Just a thought..   Trying to maybe help some.   My theory with the car tire and the softer sidewall, in a flat tire senerio will be vicious if traveling at any speed.     I have had flats on the dunlop 205 and it stays on the rim and does not flop around.    This tire has a very strong and rigid sidewall                  Thanks                    Don                        :)

It would be a plus if the car tire DIDN"T lower as much as the motorcycle tire when it goes flat.  It is hard enough getting ye old ZG1000 onto the centerstand with a fully inflated tire much less a deflated one.

I'm thinking that a CT is more puncture resistant than a MC tar to start with.

 On "Life is a Road'  Dark Side the man makes a point of not getting (less?) flats on his trips to Alaska using a car tire. He had a few before BCT.    http://lifeisaroad.com/stories/2004/10/27/theDarkSide.html

I felt it, and decided I could get it home. It had 5psi in it and was still rideable, although I wouldn't want to try dragging pegs with pressure that low."

Experimenting with something usefull would make sense but to take a precision handling machine and ruin it for more tread life makes no sense .

It made sense to the Wright brothers.
"Orville, if we cut up a half a dozen of our best bikes and make them do something different so that the tires spent less time on the ground, we could probably eliminate flat tires."
"Wilbur, do you think cutting up a dozen high dollar bikes is really worth a little better tire mileage?"
"Think of it Orville, pneumatic tires that never wear out."
"Well what if we just designed the tires differently?"
"Yeah, you're probably right Big O.  How on earth would we ever get a bike to hold the tires off the ground.  I guess it was a stupid idea."

So, some 80 years later....

Picture a streamlined bicycle with 300 seats and a big logo on the fairing declaring "CONTINENTAL BIKELINES, WE REALLY MOVE OUR PEDALS FOR YOU"
