Car tire on a bike ?
I have seen some video and discussion on the goldwing sites about using a car tire on the rear. Has anyone tried this? I think I am going to try it at the dragstrip but wanted to see if anyone has any firsthand knowledge on the subject.

when i think of a car tire bike i think of an all out drag bike with a 10" slick. goldwing guys are probably talking about a trike as alot of trikes are made from goldwings. what do you have now?

As matter of fact heres one on a supercharged Valkyrie doing the gap. Not a tire for sports, and all car tires are not created equal, but the right one on a heavy cruiser does wonders. This is a Michelin Hydroedge in a 215/60/17. Took some swing arm and fender mods to make it fit.

Sorry, but that's just plain fucking dumb for any bike NOT on the strip..there's no fucking way in hell it will come even remotely close to a bike tire in handling, even in the lamest of turns.

go to the strip and you will get plenty of hook with the bridgestone or the pilot power unless you have some crazy mods

I've seen a bunch of bikes run and the shinko's seem to be the way to go. I haven't seen one slip yet. I'll be running one of these when I stretch mine back out for the track.

This is more for land speed racing where the track is not prepped. My data aquisition is showing that i have the wheel speed varying by more than 10 mph , even at speeds over 180, with the nitrous.
My car also has the same issue and I had to add down force on the rear to get any traction at all. Since I run my 14 naked and I dont think there is any way to add down force, I was looking at improving traction. I did put on swingarm extensions since the bike wheelies too much already and I think that is only going happen more often.
I also see a fair amount of wheel spin on the street . I started looking real hard at that after an unexpected 3rd gear wheelie at the track. The same setup wouldn't wheelie in 2nd on the street due to the wheel spin.
so back to the original question , has any one tried this ?

I dont know anyone using one on a sport type bike, but know many on M109, Rocket 3, Goldwing, Valkyrie, and various and sundry other cruisers. I can tell you this traction is phenominal with the right tread pattern. As for the twistys, I also know many that get it over enough to grind pegs and leave sparks from bag guards. Of course any sporty will out corner and out run about any cruiser. All the naysayers aside, they have been successfully used on cruisers for quite a few years, and many hundreds of thousands of miles. I did the Basic MC course on the one pictured above. In the crusing circles they call it going over to the dark side, and even issue Darth Vader stickers. Lots of long range riders use them. One of my Buds went all the way to Coldfoot, Alaska above the Arctic Circle and back on one. One of the guys I know did the Bonneville thing on a supercharged Valk, and came away with 168 mph on a car tire. Contrairy to what many think, car tire is not sunomous with instant flaming death.

No, it's not, and probably fine on the strip, or at Maxton, or the flats, but I can't think of any reason why it would be good for anything else, or even as good as a tire that's actually designed for a bike....

as soon as you lean, you would be on the corner, and have a tiny contact patch vs a bike tire. fine for straight line stuff as stated(allthough it might be a lot heavier than a bike tire). if you are extended very much, even a good bike tire will spin on the street when it will wheelie on the drag strip. been there done that on a shinko ultra soft R003 190/50

Just for laughs....
Along with the comments of FBA and others on the basic integrity of a tire designed for a bike versus any other, did anyone else notice the minimal contact patch of the rear tire cornering in the photo supplied? Good luck if you deem it advisable on your bike, but no chance I would try it.
Ride safe...

All true.
The back tire on my 2003 VN1600 Classic is a Bridgestone Turanza EL400-2 195/60HR16 bought from tirerack.com for $99 plus shipping.
It *looked* way too big when it was sitting on my living room floor, but it fits the bike almost perfectly.
Six (6) stacked business cards fill the space between the drive shaft and the tire.
I've ridden it on asphalt, concrete, grass, dirt/sand, and a lime rock road. I did S-turns, U-turns, and complete circles through puddles in a Winn Dixie parking lot to see the track it would make. Four inches wide all the way.
At first the bike felt different. It took more lean to drag my floorboards, so I measured the 170/70 bike tire and the 195/60 car tire and found out why.
* 170/70 bike tire = 24-3/8" tall.
* 195/60 car tire = 26" almost exactly.
That's just over 50 fewer revolutions per mile.
I don't even feel tar snakes and most cracks in the roads.
Feels MUCH more stable on all surfaces.
No waffling at all.
That's my $166.72-worth (including installation) on the 'car-tire-on-a-bike' matter.
I put 4 pix of the tire on the bike in the Photos section here:

are you phishing for folks to join your yahoo group or clicky your links, because the fact the pics are buried there and to view one must join tends to point that way.

I've got a friend in san diego that commutes from Hemet *just on the other side of temecula* to coronado every day. His 04 vtx1800 has 120,000 miles on it with no problems. He has been running car tires since he wore his stock tire out. He did say that it handles worse in the corners, but it rides better in a straight line and the wear on them is great. It did require some modification to be done on the wheel in order to get the bead to seat. I say why not. Throw one on there, give it a run and if you don't like it then you're out of a couple hundred dollars at the most. If you do like it, then you save A LOT of money on bike tires to wear out going in a straight line. Like you said, it's not going to be your everyday street tire to go carve twisties with.

I can see it "working" on a bike that can't really turn well....any cruisers fits that compared to the 14, If you over inflate it may give a little contour, but it will never be as good as the bike tire profile.
You are asking for trouble if you do it on a 14 and if you crash.........be prepared to have the insurance company fuck you good......even if it was not your fault.
If the argument is cost...........what is safety worth?
Not that it is really a motorcycle worth riding......but......the Boss Hoss uses a Firestone P225/70R15 radial car tire on the rear as stock.

" the argument is cost..........."
+1
cost is the issue
if you can't afford the right equipment for the right mode of transportation, I suggest stay home or take a bus, maybe even ride with someone
then again, someone told me about ways to eliminate certain aspects of a certain gene pool....
I hope no Motorcycle nOOb reads this crap and thinks its the thing to try to save a dime.
was it Michelin that said your life rides on your tires?

That was in the early years, before the 230 bike tires were available ...in the past several years, they've always come equipped with the Avon 230/60/15 rear, from what I remember. While this isn't a handling machine by any standards, it's quite the beast and there's nothing in the world like a 350 V8 rumble. At Bikeweek last week, the bike that stood out amongst all the Harley's, was that Boss...it has such a distinct sound, no one could mistake that for a low-power-high-noise Harley...
