Iv chec.ked on the smallest 17" tire they make and found it to be the 205/50/17. according to specs the tires are almost the same height.the 205 is about 1 1/2 inches wider than the stock harley tire. my thinking is the 205 being low profile would pull in on each side of the stock rim and not be a problem. im also thinking it should get 20,000 miles or better.
has anyone ever done this. i tryed this on honda vtx 1800 and it worked great.i have spoke rims and also wonder if the stock tube would work.any input from someone whos done this would help
Traction or wear you choose your compromise, most choose traction on a motorcycle, thats why you don't see long life motorcycle tires.

I guess that's too much to ask though ...
Actually top brand motorcycle tires are some of the most advanced,tread design, cord construction, compound blends are all state of the art, combine that with higher quality control, and you see why they're more expensive.

It took 68 posts before somebody mentioned one of the biggest reasons for running motorcycle tires on a motorcycle.


You see how many tires the average nascar racer goes through PER RACE?
Yea they must be using old technology tires too!!


PS running car tires isn't a "WHAT ARE YOU F#$$!@ CRAZY" idea, its just a good idea to understand the pros and cons .

Unless they are Dunlops. They try a tread design and if it doesn't work they flip the tire around, give it a new number (D408) and say everhing is ok.

Actually, it's my understanding from tests done with a hardness gauge, that car tires are softer than MC tires. They certainly get better traction in wet or dry conditions.

The MC tire wears faster because it's riding on a 2" wide patch of the tire whereas a CT has much more meat on the ground. You will notice when the MC tire wears out there's generally lots of tread left on the sides unless it's the old style flat-faced tire which is just an early CT.

I'll be disappointed if I get less than 20k on the CT I have picked out but it is a performance tire. Click here to see it.

Have you thought of running a (run-flat) tire? the side wall i very thick and i have heard of guys running it all day w/o air and barely noticing the difference???

I tell my grandkids, the difference between bein cool and bein a fool is that if you have to do something to be cool, yer just bein a fool...

I do like wide tires, but I don't believe I'll be using car tires on my bike just for it to look cool. Simple fact is car tires aren't made for riding so far up the side in cornering. Do what you have to do to be cool, I came by it naturally. Never had to do a damned thing, myself. I seem to get attention no matter where I go without any attempt...

You ride by with yer 12" car tire on the back, and I'll say "damn that looks sweet" then when I ride by you layin next to yer sweet lookin bike layin on it's side on the outside of a curve on I 95, I'll say "damn, glad I don't do **** like that"

That's a good idea, and after checking on the price just now, I think I will go that route. Good extra protection.

I was going to go with "Ride On" tire sealer but a (run flat) is a better option for just a few bucks more.

Might be a stiffer ride but I'm installing some Progressive 422's soon anyway.

Running a car tire you have to counter steer a lot more then using a bike tire. It takes more input then a bike tire. Mounting will have to be done by you as neither a bike shop or tire shop want to mount one for you.
I have a buddy with a big Triumph that runs one and i have ridden it. It's a good handling bike IMHO. If they made a car tire that would fit my bike I would try it without hesitation.
I really don't thnk anyone is saying that a CT will fail on a bike. I think what most of us are saying, is that by putting a CT on a bike, there is a good chance of crashing due to handling. I personally want to put a fork lift tire on my bike so I don't get flats.

Dunlop, and maybe some others, do seem to be making some strides in dual compound tires with harder rubber in the middle and softer on the sides with longer wearing capability.

It's good to see someone finally doing this. On my two bikes I'm running Dunlop E3's exclusively except on the rear of the Train. I'm sold on the E3's. I would consider one for the back of the NT but they don't make one yet.

A little update:: This tire now has almost 56k on it. Still has plenty of tread left but going to replace it in the spring. All the chit about failure of a car tire is just what it is CHIT!! Hail to the Dark Side, live a little, don't be scared!! It's a car tire!
